Liang-Chi Hsieh eb9a4390da [SPARK-34338][SQL] Report metrics from Datasource v2 scan
### What changes were proposed in this pull request?

This patch proposes to leverage `CustomMetric`, `CustomTaskMetric` API to report custom metrics from DS v2 scan to Spark.

### Why are the changes needed?

This is related to #31398. In SPARK-34297, we want to add a couple of metrics when reading from Kafka in SS. We need some public API change in DS v2 to make it possible. This extracts only DS v2 change and make it general for DS v2 instead of micro-batch DS v2 API.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

Unit test.

Implement a simple test DS v2 class locally and run it:

```scala
scala> import org.apache.spark.sql.execution.datasources.v2._
import org.apache.spark.sql.execution.datasources.v2._

scala> classOf[CustomMetricDataSourceV2].getName
res0: String = org.apache.spark.sql.execution.datasources.v2.CustomMetricDataSourceV2

scala> val df = spark.read.format(res0).load()
df: org.apache.spark.sql.DataFrame = [i: int, j: int]

scala> df.collect
```

allisonwang-db b6bb24ca1b [SPARK-34974][SQL] Improve subquery decorrelation framework
### What changes were proposed in this pull request?
This PR implements the decorrelation technique in the paper "Unnesting Arbitrary Queries" by T. Neumann; A. Kemper
(http://www.btw-2015.de/res/proceedings/Hauptband/Wiss/Neumann-Unnesting_Arbitrary_Querie.pdf). It currently supports Filter, Project, Aggregate, Join, and UnaryNode that passes CheckAnalysis.

This feature can be controlled by the config `spark.sql.optimizer.decorrelateInnerQuery.enabled` (default: true).

A few notes:
1. This PR does not relax any constraints in CheckAnalysis for correlated subqueries, even though some cases can be supported by this new framework, such as aggregate with correlated non-equality predicates. This PR focuses on adding the new framework and making sure all existing cases can be supported. Constraints can be relaxed gradually in the future via separate PRs.
2. The new framework is only enabled for correlated scalar subqueries, as the first step. EXISTS/IN subqueries can be supported in the future.

### Why are the changes needed?
Currently, Spark has limited support for correlated subqueries. It only allows `Filter` to reference outer query columns and does not support non-equality predicates when the subquery is aggregated. This new framework will allow more operators to host outer column references and support correlated non-equality predicates and more types of operators in correlated subqueries.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Existing unit and SQL query tests and new optimizer plan tests.

Closes #32072 from allisonwang-db/spark-34974-decorrelation.

allisonwang-db bad4b6f025 [SPARK-35080][SQL] Only allow a subset of correlated equality predicates when a subquery is aggregated
### What changes were proposed in this pull request?
This PR updated the `foundNonEqualCorrelatedPred` logic for correlated subqueries in `CheckAnalysis` to only allow correlated equality predicates that guarantee one-to-one mapping between inner and outer attributes, instead of all equality predicates.

### Why are the changes needed?
To fix correctness bugs. Before this fix Spark can give wrong results for certain correlated subqueries that pass CheckAnalysis:
Example 1:
```sql
create or replace view t1(c) as values ('a'), ('b')
create or replace view t2(c) as values ('ab'), ('abc'), ('bc')

select c, (select count(*) from t2 where t1.c = substring(t2.c, 1, 1)) from t1
```
Correct results: [(a, 2), (b, 1)]
Spark results:
```
+---+-----------------+
|c  |scalarsubquery(c)|
+---+-----------------+
|a  |1                |
|a  |1                |
|b  |1                |
+---+-----------------+
```
Example 2:
```sql
create or replace view t1(a, b) as values (0, 6), (1, 5), (2, 4), (3, 3);
create or replace view t2(c) as values (6);

select c, (select count(*) from t1 where a + b = c) from t2;
```
Correct results: [(6, 4)]
Spark results:
```
+---+-----------------+
|c  |scalarsubquery(c)|
+---+-----------------+
|6  |1                |
|6  |1                |
|6  |1                |
|6  |1                |
+---+-----------------+
```
### Does this PR introduce _any_ user-facing change?
Yes. Users will not be able to run queries that contain unsupported correlated equality predicates.

### How was this patch tested?
Added unit tests.

Closes #32179 from allisonwang-db/spark-35080-subquery-bug.

Yingyi Bu 9a6d7730f5 [SPARK-35103][SQL] Make TypeCoercion rules more efficient
## What changes were proposed in this pull request?
This PR fixes a couple of things in TypeCoercion rules:
- Only run the propagate types step if the children of a node have output attributes with changed dataTypes and/or nullability. This is implemented as custom tree transformation. The TypeCoercion rules now only implement a partial function.
- Combine multiple type coercion rules into a single rule. Multiple rules are applied in single tree traversal.
- Reduce calls to conf.get in DecimalPrecision. This now happens once per tree traversal, instead of once per matched expression.
- Reduce the use of withNewChildren.

This brings down the number of CPU cycles spend in analysis by ~28% (benchmark: 10 iterations of all TPC-DS queries on SF10).

## How was this patch tested?
Existing tests.

Max Gekk 1d1ed3eb25 [SPARK-35107][SQL] Parse unit-to-unit interval literals to ANSI intervals
### What changes were proposed in this pull request?
Parse the year-month interval literals like `INTERVAL '1-1' YEAR TO MONTH` to values of `YearMonthIntervalType`, and day-time interval literals to `DayTimeIntervalType` values. Currently, Spark SQL supports:
- DAY TO HOUR
- DAY TO MINUTE
- DAY TO SECOND
- HOUR TO MINUTE
- HOUR TO SECOND
- MINUTE TO SECOND

All such interval literals are converted to `DayTimeIntervalType`, and `YEAR TO MONTH` to `YearMonthIntervalType` while loosing info about `from` and `to` units.

**Note**: new behavior is under the SQL config `spark.sql.legacy.interval.enabled` which is `false` by default. When the config is set to `true`, the interval literals are parsed to `CaledarIntervalType` values.

Closes #32176

### Why are the changes needed?
To conform the ANSI SQL standard which assumes conversions of interval literals to year-month or day-time interval but not to mixed interval type like Catalyst's `CalendarIntervalType`.

### Does this PR introduce _any_ user-facing change?
Yes.

Before:
```sql
spark-sql> SELECT INTERVAL '1 01:02:03.123' DAY TO SECOND;
1 days 1 hours 2 minutes 3.123 seconds
spark-sql> SELECT typeof(INTERVAL '1 01:02:03.123' DAY TO SECOND);
interval
```

After:
```sql
spark-sql> SELECT INTERVAL '1 01:02:03.123' DAY TO SECOND;
1 01:02:03.123000000
spark-sql> SELECT typeof(INTERVAL '1 01:02:03.123' DAY TO SECOND);
day-time interval
```

### How was this patch tested?
1. By running the affected test suites:
```
$ ./build/sbt "test:testOnly *.ExpressionParserSuite"
$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z interval.sql"
$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z create_view.sql"
$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z date.sql"
$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z timestamp.sql"
```
2. PostgresSQL tests are executed with `spark.sql.legacy.interval.enabled` is set to `true` to keep compatibility with PostgreSQL output:
```sql
> SELECT interval '999' second;
0 years 0 mons 0 days 0 hours 16 mins 39.00 secs
```

Terry Kim 7a06cdd53b [SPARK-35122][SQL] Migrate CACHE/UNCACHE TABLE to use AnalysisOnlyCommand
### What changes were proposed in this pull request?

Now that `AnalysisOnlyCommand` in introduced in #32032, `CacheTable` and `UncacheTable` can extend `AnalysisOnlyCommand` to simplify the code base. For example, the logic to handle these commands such that the tables are only analyzed is scattered across different places.

### Does this PR introduce _any_ user-facing change?

No, just internal refactoring.

### How was this patch tested?

The existing tests (e.g., `CachedTableSuite`) cover the changes in this PR. For example, if I make `CacheTable`/`UncacheTable` extend `LeafCommand`, there are few failures in `CachedTableSuite`.

Peter Toth c8d78a70b4 [SPARK-34581][SQL] Don't optimize out grouping expressions from aggregate expressions without aggregate function
### What changes were proposed in this pull request?
This PR:
- Adds a new expression `GroupingExprRef` that can be used in aggregate expressions of `Aggregate` nodes to refer grouping expressions by index. These expressions capture the data type and nullability of the referred grouping expression.
- Adds a new rule `EnforceGroupingReferencesInAggregates` that inserts the references in the beginning of the optimization phase.
- Adds a new rule `UpdateGroupingExprRefNullability` to update nullability of `GroupingExprRef` expressions as nullability of referred grouping expression can change during optimization.

### Why are the changes needed?
If aggregate expressions (without aggregate functions) in an `Aggregate` node are complex then the `Optimizer` can optimize out grouping expressions from them and so making aggregate expressions invalid.

Here is a simple example:
```
SELECT not(t.id IS NULL) , count(*)
FROM t
GROUP BY t.id IS NULL
```
In this case the `BooleanSimplification` rule does this:
```
=== Applying Rule org.apache.spark.sql.catalyst.optimizer.BooleanSimplification ===
!Aggregate [isnull(id#222)], [NOT isnull(id#222) AS (NOT (id IS NULL))#226, count(1) AS c#224L]   Aggregate [isnull(id#222)], [isnotnull(id#222) AS (NOT (id IS NULL))#226, count(1) AS c#224L]
 +- Project [value#219 AS id#222]                                                                 +- Project [value#219 AS id#222]
    +- LocalRelation [value#219]                                                                     +- LocalRelation [value#219]
```
where `NOT isnull(id#222)` is optimized to `isnotnull(id#222)` and so it no longer refers to any grouping expression.

Before this PR:
```
== Optimized Logical Plan ==
Aggregate [isnull(id#222)], [isnotnull(id#222) AS (NOT (id IS NULL))#234, count(1) AS c#232L]
+- Project [value#219 AS id#222]
   +- LocalRelation [value#219]
```
and running the query throws an error:
```
Couldn't find id#222 in [isnull(id#222)#230,count(1)#226L]
java.lang.IllegalStateException: Couldn't find id#222 in [isnull(id#222)#230,count(1)#226L]
```

After this PR:
```
== Optimized Logical Plan ==
Aggregate [isnull(id#222)], [NOT groupingexprref(0) AS (NOT (id IS NULL))#234, count(1) AS c#232L]
+- Project [value#219 AS id#222]
   +- LocalRelation [value#219]
```
and the query works.

### Does this PR introduce _any_ user-facing change?
Yes, the query works.

### How was this patch tested?
Added new UT.

beliefer 03191e8d8f [SPARK-35116][SQL][TESTS] The generated data fits the precision of DayTimeIntervalType in spark
### What changes were proposed in this pull request?
The precision of `java.time.Duration` is nanosecond, but when it is used as `DayTimeIntervalType` in Spark, it is microsecond.
At present, the `DayTimeIntervalType` data generated in the implementation of `RandomDataGenerator` is accurate to nanosecond, which will cause the `DayTimeIntervalType` to be converted to long, and then back to `DayTimeIntervalType` to lose the accuracy, which will cause the test to fail. For example: https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/137390/testReport/org.apache.spark.sql.hive.execution/HashAggregationQueryWithControlledFallbackSuite/udaf_with_all_data_types/

### Does this PR introduce _any_ user-facing change?
'No'. Just change the test class.

This issue fixes an issue that indentation of multiple output JSON records in a single split file are broken except for the first record in the split when `pretty` option is `true`.
```
// Run in the Spark Shell.
// Set spark.sql.leafNodeDefaultParallelism to 1 for the current master.
// Or set spark.default.parallelism for the previous releases.
spark.conf.set("spark.sql.leafNodeDefaultParallelism", 1)
val df = Seq("a", "b", "c").toDF
df.write.option("pretty", "true").json("/path/to/output")

# Run in a Shell
$ cat /path/to/output/*.json
{
  "value" : "a"
}
 {
  "value" : "b"
}
 {
  "value" : "c"
}
```

### Why are the changes needed?

It's not pretty even though `pretty` option is true.

### Does this PR introduce _any_ user-facing change?

I think "No". Indentation style is changed but JSON format is not changed.

### How was this patch tested?

Max Gekk 3f4c32b3ca [SPARK-35099][SQL] Convert ANSI interval literals to SQL string in ANSI style
### What changes were proposed in this pull request?
Handle `YearMonthIntervalType` and `DayTimeIntervalType` in the `sql()` and `toString()` method of `Literal`, and format the ANSI interval in the ANSI style.

### Why are the changes needed?
To improve readability and UX with Spark SQL. For example, a test output before the changes:
```
-- !query
select timestamp'2011-11-11 11:11:11' - interval '2' day
-- !query schema
struct<TIMESTAMP '2011-11-11 11:11:11' - 172800000000:timestamp>
-- !query output
2011-11-09 11:11:11
```

### Does this PR introduce _any_ user-facing change?
Should not since the new intervals haven't been released yet.

### How was this patch tested?
By running new tests:
```
$ ./build/sbt "test:testOnly *LiteralExpressionSuite"
```

Max Gekk de9e8b6c94 [SPARK-35051][SQL] Support add/subtract of a day-time interval to/from a date
### What changes were proposed in this pull request?
Support `date +/- day-time interval`. In the PR, I propose to update the binary arithmetic rules, and cast an input date to a timestamp at the session time zone, and then add a day-time interval to it.

### Why are the changes needed?
1. To conform the ANSI SQL standard which requires to support such operation over dates and intervals:
<img width="811" alt="Screenshot 2021-03-12 at 11 36 14" src="https://user-images.githubusercontent.com/1580697/111081674-865d4900-8515-11eb-86c8-3538ecaf4804.png">
2. To fix the regression comparing to the recent Spark release 3.1 with default settings.

Before the changes:
```sql
spark-sql> select date'now' + (timestamp'now' - timestamp'yesterday');
Error in query: cannot resolve 'DATE '2021-04-14' + subtracttimestamps(TIMESTAMP '2021-04-14 18:14:56.497', TIMESTAMP '2021-04-13 00:00:00')' due to data type mismatch: argument 1 requires timestamp type, however, 'DATE '2021-04-14'' is of date type.; line 1 pos 7;

+- OneRowRelation
```

Spark 3.1:
```sql
spark-sql> select date'now' + (timestamp'now' - timestamp'yesterday');
2021-04-15
```

Hive:
```sql

+------------------------+
| 2021-04-15 18:15:30.0  |

```

### Does this PR introduce _any_ user-facing change?
Should not since new intervals have not been released yet.

After the changes:
```sql
spark-sql> select date'now' + (timestamp'now' - timestamp'yesterday');
2021-04-15 18:13:16.555

Terry Kim b5241c97b1 [SPARK-34701][SQL] Introduce AnalysisOnlyCommand that allows its children to be removed once the command is marked as analyzed
### What changes were proposed in this pull request?

This PR proposes to introduce the `AnalysisOnlyCommand` trait such that a command that extends this trait can have its children only analyzed, but not optimized. There is a corresponding analysis rule `HandleAnalysisOnlyCommand` that marks the command as analyzed after all other analysis rules are run.

This can be useful if a logical plan has children where they need to be only analyzed, but not optimized - e.g., `CREATE VIEW` or `CACHE TABLE AS`. This also addresses the issue found in #31933.

This PR also updates `CreateViewCommand`, `CacheTableAsSelect`, and `AlterViewAsCommand` to use the new trait / rule such that their children are only analyzed.

### Why are the changes needed?

To address the issue where the plan is unnecessarily re-analyzed in `CreateViewCommand`.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Existing tests should cover the changes.

Karen Feng 816f6dd13e [SPARK-34527][SQL] Resolve duplicated common columns from USING/NATURAL JOIN
### What changes were proposed in this pull request?

Adds the duplicated common columns as hidden columns to the Projection used to rewrite NATURAL/USING JOINs.

### Why are the changes needed?

Allows users to resolve either side of the NATURAL/USING JOIN's common keys.
Previously, the user could only resolve the following columns:

| Join type | Left key columns | Right key columns |
| --- | --- | --- |
| Inner | Yes | No |
| Left | Yes | No |
| Right | No | Yes |
| Outer | No | No |

### Does this PR introduce _any_ user-facing change?

Yes. The user can now symmetrically resolve the common columns from a NATURAL/USING JOIN.

### How was this patch tested?

SQL-side tests. The behavior matches PostgreSQL and MySQL.

Kousuke Saruta ef05e89ee5 [SPARK-34977][SQL] LIST FILES/JARS/ARCHIVES cannot handle multiple arguments properly when at least one path is quoted
### What changes were proposed in this pull request?

This PR fixes an issue that `LIST FILES/JARS/ARCHIVES path1 path2 ...` cannot list all paths if at least one path is quoted.
An example here.
```
ADD FILE /tmp/test1;
ADD FILE /tmp/test2;

LIST FILES /tmp/test1 /tmp/test2;
file:/tmp/test1
file:/tmp/test2

LIST FILES /tmp/test1 "/tmp/test2";
file:/tmp/test2
```

In this example, the second `LIST FILES` doesn't show `file:/tmp/test1`.

To resolve this issue, I modified the syntax rule to be able to handle this case.
I also changed `SparkSQLParser` to be able to handle paths which contains white spaces.

### Why are the changes needed?

This is a bug.
I also have a plan which extends `ADD FILE/JAR/ARCHIVE` to take multiple paths like Hive and the syntax rule change is necessary for that.

### Does this PR introduce _any_ user-facing change?

Yes. Users can pass quoted paths when using `ADD FILE/JAR/ARCHIVE`.

### How was this patch tested?

New test.

Chao Sun 1a6708918b [SPARK-34947][SQL] Streaming write to a V2 table should invalidate its associated cache
### What changes were proposed in this pull request?

Populate table catalog and identifier from `DataStreamWriter` to `WriteToMicroBatchDataSource` so that we can invalidate cache for tables that are updated by a streaming write.

This is somewhat related [SPARK-27484](https://issues.apache.org/jira/browse/SPARK-27484) and [SPARK-34183](https://issues.apache.org/jira/browse/SPARK-34183) (#31700), as ideally we may want to replace `WriteToMicroBatchDataSource` and `WriteToDataSourceV2` with logical write nodes and feed them to analyzer. That will potentially change the code path involved in this PR.

### Why are the changes needed?

Currently `WriteToDataSourceV2` doesn't have cache invalidation logic, and therefore, when the target table for a micro batch streaming job is cached, the cache entry won't be removed when the table is updated.

### Does this PR introduce _any_ user-facing change?

Yes now when a DSv2 table which supports streaming write is updated by a streaming job, its cache will also be invalidated.

### How was this patch tested?

Added a new UT.

allisonwang-db 6b8405b574 [SPARK-28379][SQL] Allow non-aggregated single row correlated scalar subquery
### What changes were proposed in this pull request?
This PR allows non-aggregated correlated scalar subquery if the max output row is less than 2. Correlated scalar subqueries need to be aggregated because they are going to be decorrelated and rewritten as LEFT OUTER joins. If the correlated scalar subquery produces more than one output row, the rewrite will yield wrong results.

But this constraint can be relaxed when the subquery plan's the max number of output rows is less than or equal to 1.

To relax a constraint in CheckAnalysis for the correlated scalar subquery.

1. **Union**: number of rows in output will be the sum of number of rows in the output for each child of union, min and max for each column in the output will be the min and max of that particular column coming from its children.
Example:
Table 1
a   b
1   6
2   3
Table 2
a   b
1   3
 4   1
stats for table1 union table2 would be number of rows = 4, columnStats = (a: {min: 1, max: 4}, b: {min: 1, max: 6})

2. **Sort**: row and columns stats would be same as its children.

3. **Range**: number of output rows and distinct count will be equal to number of elements, min and max is calculated from start, end and step param.

### Why are the changes needed?
The change will enhance the feature https://issues.apache.org/jira/browse/SPARK-16026 and will help in other stats based optimizations.

### Does this PR introduce _any_ user-facing change?

Max Gekk 26f312e95f [SPARK-35037][SQL] Recognize sign before the interval string in literals
### What changes were proposed in this pull request?
1. Extend SQL syntax rules to support a sign before the interval strings of ANSI year-month and day-time intervals.
2. Recognize `-` in `AstBuilder` and negate parsed intervals.

### Why are the changes needed?
To conform to the SQL standard which allows a sign before the string interval, see `"5.3 <literal>"`:
```
<interval literal> ::=
  INTERVAL [ <sign> ] <interval string> <interval qualifier>
<interval string> ::=
  <quote> <unquoted interval string> <quote>
<unquoted interval string> ::=
  [ <sign> ] { <year-month literal> | <day-time literal> }
<sign> ::=
    <plus sign>
  | <minus sign>
```

### Does this PR introduce _any_ user-facing change?
Should not because it just extends supported intervals syntax.

### How was this patch tested?
By running new tests in `interval.sql`:
```
$ build/sbt "sql/testOnly *SQLQueryTestSuite -- -z interval.sql"

angerszhu 278203d969 [SPARK-28227][SQL] Support projection, aggregate/window functions, and lateral view in the TRANSFORM clause
### What changes were proposed in this pull request?
For Spark SQL, it can't support script transform SQL with aggregationClause/windowClause/LateralView.
This case we can't directly migration Hive SQL to Spark SQL.

In this PR, we treat all script transform statement's query part (exclude transform about part)  as a  separate query block and solve it as ScriptTransformation's child and pass a UnresolvedStart as ScriptTransform's input. Then in analyzer level, we pass child's output as ScriptTransform's input. Then we can support all kind of normal SELECT query combine with script transformation.

Such as transform with aggregation:
```
SELECT TRANSFORM ( d2, max(d1) as max_d1, sum(d3))
USING 'cat' AS (a,b,c)
FROM script_trans
WHERE d1 <= 100
GROUP BY d2
 HAVING max_d1 > 0
```
When we build AST, we treat it as
```
SELECT TRANSFORM (*)
USING 'cat' AS (a,b,c)
FROM (
     SELECT  d2, max(d1) as max_d1, sum(d3)
     FROM script_trans
    WHERE d1 <= 100
    GROUP BY d2
    HAVING max_d1 > 0
) tmp
```
then in Analyzer's `ResolveReferences`, resolve `* (UnresolvedStar)`, then sql behavior like
```
SELECT TRANSFORM ( d2, max(d1) as max_d1, sum(d3))
USING 'cat' AS (a,b,c)
FROM script_trans
WHERE d1 <= 100
GROUP BY d2
HAVING max_d1 > 0
```

About UT, in this pr we add a lot of different SQL to check we can support all kind of such SQL and  each kind of expressions can work well, such as alias, case when, binary compute etc...

### Why are the changes needed?
Support transform with aggregateClause/windowClause/LateralView etc , make sql migration more smoothly

### Does this PR introduce _any_ user-facing change?
User can write transform with  aggregateClause/windowClause/LateralView.

### How was this patch tested?
Added UT

```
In this pr, we have done two things as below:

1. Support partial grouping analytics such as `group by a, cube(a, b)`
2. Support mixed grouping analytics such as `group by cube(a, b), rollup(b,c)`

*Partial Groupings*

    Partial Groupings means there are both `group_expression` and `CUBE|ROLLUP|GROUPING SETS`
    in GROUP BY clause. For example:
    `GROUP BY warehouse, CUBE(product, location)` is equivalent to
    `GROUP BY GROUPING SETS((warehouse, product, location), (warehouse, product), (warehouse, location), (warehouse))`.
    `GROUP BY warehouse, ROLLUP(product, location)` is equivalent to
    `GROUP BY GROUPING SETS((warehouse, product, location), (warehouse, product), (warehouse))`.
    `GROUP BY warehouse, GROUPING SETS((product, location), (producet), ())` is equivalent to
    `GROUP BY GROUPING SETS((warehouse, product, location), (warehouse, location), (warehouse))`.

*Concatenated Groupings*

    Concatenated groupings offer a concise way to generate useful combinations of groupings. Groupings specified
    with concatenated groupings yield the cross-product of groupings from each grouping set. The cross-product
    operation enables even a small number of concatenated groupings to generate a large number of final groups.
    The concatenated groupings are specified simply by listing multiple `GROUPING SETS`, `CUBES`, and `ROLLUP`,
    and separating them with commas. For example:
    `GROUP BY GROUPING SETS((warehouse), (producet)), GROUPING SETS((location), (size))` is equivalent to
    `GROUP BY GROUPING SETS((warehouse, location), (warehouse, size), (product, location), (product, size))`.
    `GROUP BY CUBE((warehouse), (producet)), ROLLUP((location), (size))` is equivalent to
    `GROUP BY GROUPING SETS((warehouse, product), (warehouse), (producet), ()), GROUPING SETS((location, size), (location), ())`
    `GROUP BY GROUPING SETS(
        (warehouse, product, location, size), (warehouse, product, location), (warehouse, product),
        (warehouse, location, size), (warehouse, location), (warehouse),
        (product, location, size), (product, location), (product),
        (location, size), (location), ())`.
    `GROUP BY order, CUBE((warehouse), (producet)), ROLLUP((location), (size))` is equivalent to
    `GROUP BY order, GROUPING SETS((warehouse, product), (warehouse), (producet), ()), GROUPING SETS((location, size), (location), ())`
    `GROUP BY GROUPING SETS(
        (order, warehouse, product, location, size), (order, warehouse, product, location), (order, warehouse, product),
        (order, warehouse, location, size), (order, warehouse, location), (order, warehouse),
        (order, product, location, size), (order, product, location), (order, product),
        (order, location, size), (order, location), (order))`.

### Why are the changes needed?

Yingyi Bu 3db8ec258c [SPARK-34916][SQL] Add condition lambda and rule id to the transform family for early stopping
### What changes were proposed in this pull request?

This PR contains:
- TreeNode, QueryPlan, AnalysisHelper changes to allow the transform function family to stop earlier without traversing the entire tree;
- Example changes in a few rules to support such pruning, e.g., ReorderJoin and OptimizeIn.

Here is a [design doc](https://docs.google.com/document/d/1SEUhkbo8X-0cYAJFYFDQhxUnKJBz4lLn3u4xR2qfWqk) that elaborates the ideas and benchmark numbers.

### Why are the changes needed?

It's a framework-level change for reducing the query compilation time.
In particular, if we update existing rules and transform call sites as per the examples in this PR, the analysis time and query optimization time can be reduced as described in this [doc](https://docs.google.com/document/d/1SEUhkbo8X-0cYAJFYFDQhxUnKJBz4lLn3u4xR2qfWqk) .

### Does this PR introduce _any_ user-facing change?

Max Gekk 0e761c7307 [SPARK-35016][SQL] Format ANSI intervals in Hive style
### What changes were proposed in this pull request?
1. Extend `IntervalUtils` methods: `toYearMonthIntervalString` and `toDayTimeIntervalString` to support formatting of year-month/day-time intervals in Hive style. The methods get new parameter style which can have to values; `HIVE_STYLE` and `ANSI_STYLE`.
2. Invoke `toYearMonthIntervalString` and `toDayTimeIntervalString` from the `Cast` expression with the `style` parameter is set to `ANSI_STYLE`.
3. Invoke `toYearMonthIntervalString` and `toDayTimeIntervalString` from `HiveResult` with `style` is set to `HIVE_STYLE`.

### Why are the changes needed?
The `spark-sql` shell formats its output in Hive style by using `HiveResult.hiveResultString()`. The changes are needed to match Hive behavior. For instance,

Hive:
```sql
0: jdbc:hive2://localhost:10000/default> select timestamp'2021-01-01 01:02:03.000001' - date'2020-12-31';
+-----------------------+
|          _c0          |
+-----------------------+
| 1 01:02:03.000001000  |
+-----------------------+
```

Spark before the changes:
```sql
spark-sql> select timestamp'2021-01-01 01:02:03.000001' - date'2020-12-31';
INTERVAL '1 01:02:03.000001' DAY TO SECOND
```

Also this should unblock #32099 which enables *.sql tests in `SQLQueryTestSuite`.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes:
```sql
spark-sql> select timestamp'2021-01-01 01:02:03.000001' - date'2020-12-31';
1 01:02:03.000001000
```

### How was this patch tested?
1. Added new tests to `IntervalUtilsSuite`:
```
$  build/sbt "test:testOnly *IntervalUtilsSuite"
```
2. Modified existing tests in `HiveResultSuite`:
```
$  build/sbt -Phive-2.3 -Phive-thriftserver "testOnly *HiveResultSuite"
```
3. By running cast tests:
```
$ build/sbt "testOnly *CastSuite*"
```

### What changes were proposed in this pull request?

This patch proposes a fix of nested column pruning for extracting case-insensitive struct field from array of struct.

### Why are the changes needed?

Under case-insensitive mode, nested column pruning rule cannot correctly push down extractor of a struct field of an array of struct, e.g.,

Ali Afroozeh 0945baf906 [SPARK-34989] Improve the performance of mapChildren and withNewChildren methods
### What changes were proposed in this pull request?
One of the main performance bottlenecks in query compilation is overly-generic tree transformation methods, namely `mapChildren` and `withNewChildren` (defined in `TreeNode`). These methods have an overly-generic implementation to iterate over the children and rely on reflection to create new instances. We have observed that, especially for queries with large query plans, a significant amount of CPU cycles are wasted in these methods. In this PR we make these methods more efficient, by delegating the iteration and instantiation to concrete node types. The benchmarks show that we can expect significant performance improvement in total query compilation time in queries with large query plans (from 30-80%) and about 20% on average.

#### Problem detail
The `mapChildren` method in `TreeNode` is overly generic and costly. To be more specific, this method:
- iterates over all the fields of a node using Scala’s product iterator. While the iteration is not reflection-based, thanks to the Scala compiler generating code for `Product`, we create many anonymous functions and visit many nested structures (recursive calls).
The anonymous functions (presumably compiled to Java anonymous inner classes) also show up quite high on the list in the object allocation profiles, so we are putting unnecessary pressure on GC here.
- does a lot of comparisons. Basically for each element returned from the product iterator, we check if it is a child (contained in the list of children) and then transform it. We can avoid that by just iterating over children, but in the current implementation, we need to gather all the fields (only transform the children) so that we can instantiate the object using the reflection.
- creates objects using reflection, by delegating to the `makeCopy` method, which is several orders of magnitude slower than using the constructor.

#### Solution
The proposed solution in this PR is rather straightforward: we rewrite the `mapChildren` method using the `children` and `withNewChildren` methods. The default `withNewChildren` method suffers from the same problems as `mapChildren` and we need to make it more efficient by specializing it in concrete classes.  Similar to how each concrete query plan node already defines its children, it should also define how they can be constructed given a new list of children. Actually, the implementation is quite simple in most cases and is a one-liner thanks to the copy method present in Scala case classes. Note that we cannot abstract over the copy method, it’s generated by the compiler for case classes if no other type higher in the hierarchy defines it. For most concrete nodes, the implementation of `withNewChildren` looks like this:
```
override def withNewChildren(newChildren: Seq[LogicalPlan]): LogicalPlan = copy(children = newChildren)
```
The current `withNewChildren` method has two properties that we should preserve:

- It returns the same instance if the provided children are the same as its children, i.e., it preserves referential equality.
- It copies tags and maintains the origin links when a new copy is created.

These properties are hard to enforce in the concrete node type implementation. Therefore, we propose a template method `withNewChildrenInternal` that should be rewritten by the concrete classes and let the `withNewChildren` method take care of referential equality and copying:
```
override def withNewChildren(newChildren: Seq[LogicalPlan]): LogicalPlan = {
 if (childrenFastEquals(children, newChildren)) {
   this
 } else {
   CurrentOrigin.withOrigin(origin) {
     val res = withNewChildrenInternal(newChildren)
     res.copyTagsFrom(this)
     res
   }
 }
}
```

With the refactoring done in a previous PR (https://github.com/apache/spark/pull/31932) most tree node types fall in one of the categories of `Leaf`, `Unary`, `Binary` or `Ternary`. These traits have a more efficient implementation for `mapChildren` and define a more specialized version of `withNewChildrenInternal` that avoids creating unnecessary lists. For example, the `mapChildren` method in `UnaryLike` is defined as follows:
```
  override final def mapChildren(f: T => T): T = {
    val newChild = f(child)
    if (newChild fastEquals child) {
      this.asInstanceOf[T]
    } else {
      CurrentOrigin.withOrigin(origin) {
        val res = withNewChildInternal(newChild)
        res.copyTagsFrom(this.asInstanceOf[T])
        res
      }
    }
  }
```

#### Results
With this PR, we have observed significant performance improvements in query compilation time, more specifically in the analysis and optimization phases. The table below shows the TPC-DS queries that had more than 25% speedup in compilation times. Biggest speedups are observed in queries with large query plans.
| Query  | Speedup |
| ------------- | ------------- |
|q4    |29%|
|q9    |81%|
|q14a  |31%|
|q14b  |28%|
|q22   |33%|
|q33   |29%|
|q34   |25%|
|q39   |27%|
|q41   |27%|
|q44   |26%|
|q47   |28%|
|q48   |76%|
|q49   |46%|
|q56   |26%|
|q58   |43%|
|q59   |46%|
|q60   |50%|
|q65   |59%|
|q66   |46%|
|q67   |52%|
|q69   |31%|
|q70   |30%|
|q96   |26%|
|q98   |32%|

#### Binary incompatibility
Changing the `withNewChildren` in `TreeNode` breaks the binary compatibility of the code compiled against older versions of Spark because now it is expected that concrete `TreeNode` subclasses all implement the `withNewChildrenInternal` method. This is a problem, for example, when users write custom expressions. This change is the right choice, since it forces all newly added expressions to Catalyst implement it in an efficient manner and will prevent future regressions.
Please note that we have not completely removed the old implementation and renamed it to `legacyWithNewChildren`. This method will be removed in the future and for now helps the transition. There are expressions such as `UpdateFields` that have a complex way of defining children. Writing `withNewChildren` for them requires refactoring the expression. For now, these expressions use the old, slow method. In a future PR we address these expressions.

### Does this PR introduce _any_ user-facing change?

This PR does not introduce user facing changes but my break binary compatibility of the code compiled against older versions. See the binary compatibility section.

### How was this patch tested?

This PR is mainly a refactoring and passes existing tests.

Tathagata Das c1c9a318c2 [SPARK-34962][SQL] Explicit representation of * in UpdateAction and InsertAction in MergeIntoTable
### What changes were proposed in this pull request?
Change UpdateAction and InsertAction of MergeIntoTable to explicitly represent star,

### Why are the changes needed?
Currently, UpdateAction and InsertAction in the MergeIntoTable implicitly represent `update set *` and `insert *` with empty assignments. That means there is no way to differentiate between the representations of "update all columns" and "update no columns". For SQL MERGE queries, this inability does not matter because the SQL MERGE grammar that generated the MergeIntoTable plan does not allow "update no columns". However, other ways of generating the MergeIntoTable plan may not have that limitation, and may want to allow specifying "update no columns". For example, in the Delta Lake project we provide a type-safe Scala API for Merge, where it is perfectly valid to produce a Merge query with an update clause but no update assignments. Currently, we cannot use MergeIntoTable to represent this plan, thus complicating the generation, and resolution of merge query from scala API.

Side note: fixed another bug where a merge plan with star and no other expressions with unresolved attributes (e.g. all non-optional predicates are `literal(true)`), then resolution will be skipped and star wont expanded. added test for that.

allisonwang-db ac01070a77 [SPARK-34946][SQL] Block unsupported correlated scalar subquery in Aggregate
### What changes were proposed in this pull request?
This PR adds two additional checks in `CheckAnalysis` for correlated scalar subquery in Aggregate. It blocks the cases that Spark do not currently support based on the rewrite logic in `RewriteCorrelatedScalarSubquery`:
aff6c0febb/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/subquery.scala (L618-L624)

### Why are the changes needed?
It can be confusing to users when their queries pass the check analysis but cannot be executed. Also, the error messages are confusing:

#### Case 1: correlated scalar subquery in the grouping expressions but not in aggregate expressions

```sql
SELECT SUM(c2) FROM t t1 GROUP BY (SELECT SUM(c2) FROM t t2 WHERE t1.c1 = t2.c1)
```
We get this error:
```
java.lang.AssertionError: assertion failed: Expects 1 field, but got 2; something went wrong in analysis
```
because the correlated scalar subquery is not rewritten properly:
```scala
== Optimized Logical Plan ==
Aggregate [scalar-subquery#5 [(c1#6 = c1#6#93)]], [sum(c2#7) AS sum(c2)#11L]
:  +- Aggregate [c1#6], [sum(c2#7) AS sum(c2)#15L, c1#6 AS c1#6#93]
:     +- LocalRelation [c1#6, c2#7]
+- LocalRelation [c1#6, c2#7]
```

#### Case 2: correlated scalar subquery in the aggregate expressions but not in the grouping expressions

```sql
SELECT (SELECT SUM(c2) FROM t t2 WHERE t1.c1 = t2.c1), SUM(c2) FROM t t1 GROUP BY c1
```
We get this error:
```
java.lang.IllegalStateException: Couldn't find sum(c2)#69L in [c1#60,sum(c2#61)#64L]
```
because the transformed correlated scalar subquery output is not present in the grouping expression of the Aggregate:
```scala
== Optimized Logical Plan ==
Aggregate [c1#60], [sum(c2)#69L AS scalarsubquery(c1)#70L, sum(c2#61) AS sum(c2)#65L]
+- Project [c1#60, c2#61, sum(c2)#69L]
   +- Join LeftOuter, (c1#60 = c1#60#95)
      :- LocalRelation [c1#60, c2#61]
      +- Aggregate [c1#60], [sum(c2#61) AS sum(c2)#69L, c1#60 AS c1#60#95]

Ryan Blue 3c7d6c38e8 [SPARK-27658][SQL] Add FunctionCatalog API
## What changes were proposed in this pull request?

This adds a new API for catalog plugins that exposes functions to Spark. The API can list and load functions. This does not include create, delete, or alter operations.
- [Design Document](https://docs.google.com/document/d/1PLBieHIlxZjmoUB0ERF-VozCRJ0xw2j3qKvUNWpWA2U/edit?usp=sharing)

There are 3 types of functions defined:
* A `ScalarFunction` that produces a value for every call
* An `AggregateFunction` that produces a value after updates for a group of rows

Functions loaded from the catalog by name as `UnboundFunction`. Once input arguments are determined `bind` is called on the unbound function to get a `BoundFunction` implementation that is one of the 3 types above. Binding can fail if the function doesn't support the input type. `BoundFunction` returns the result type produced by the function.

## How was this patch tested?

This includes a test that demonstrates the new API.

Closes #24559 from rdblue/SPARK-27658-add-function-catalog-api.

allisonwang-db 0aa2c284e4 [SPARK-34678][SQL] Add table function registry
### What changes were proposed in this pull request?
This PR extends the current function registry and catalog to support table-valued functions by adding a table function registry. It also refactors `range` to be a built-in function in the table function registry.

### Why are the changes needed?
Currently, Spark resolves table-valued functions very differently from the other functions. This change is to make the behavior for table and non-table functions consistent. It also allows Spark to display information about built-in table-valued functions:
Before:
```scala
scala> sql("describe function range").show(false)
+--------------------------+
|function_desc             |
+--------------------------+
|Function: range not found.|
+--------------------------+
```
After:
```scala
Function: range
Class: org.apache.spark.sql.catalyst.plans.logical.Range
Usage:
  range(start: Long, end: Long, step: Long, numPartitions: Int)
  range(start: Long, end: Long, step: Long)
  range(start: Long, end: Long)
  range(end: Long)

// Extended
Function: range
Class: org.apache.spark.sql.catalyst.plans.logical.Range
Usage:
  range(start: Long, end: Long, step: Long, numPartitions: Int)
  range(start: Long, end: Long, step: Long)
  range(start: Long, end: Long)
  range(end: Long)

Extended Usage:
  Examples:
    > SELECT * FROM range(1);
      +---+
      | id|
      +---+
      |  0|
      +---+
    > SELECT * FROM range(0, 2);
      +---+
      |id |
      +---+
      |0  |
      |1  |
      +---+
    > SELECT range(0, 4, 2);
      +---+
      |id |
      +---+
      |0  |
      |2  |
      +---+

    Since: 2.0.0
```

### Does this PR introduce _any_ user-facing change?
Yes. User will not be able to create a function with name `range` in the default database:
Before:
```scala
scala> sql("create function range as 'range'")
res3: org.apache.spark.sql.DataFrame = []
```
After:
```
scala> sql("create function range as 'range'")
org.apache.spark.sql.catalyst.analysis.FunctionAlreadyExistsException: Function 'default.range' already exists in database 'default'
```

Tanel Kiis 7c8dc5e0b5 [SPARK-34922][SQL] Use a relative cost comparison function in the CBO
### What changes were proposed in this pull request?

Changed the cost comparison function of the CBO to use the ratios of row counts and sizes in bytes.

### Why are the changes needed?

In #30965 we changed to CBO cost comparison function so it would be "symetric": `A.betterThan(B)` now implies, that `!B.betterThan(A)`.
With that we caused a performance regressions in some queries - TPCDS q19 for example.

The original cost comparison function used the ratios `relativeRows = A.rowCount / B.rowCount` and `relativeSize = A.size / B.size`. The changed function compared "absolute" cost values `costA = w*A.rowCount + (1-w)*A.size` and `costB = w*B.rowCount + (1-w)*B.size`.

Given the input from wzhfy we decided to go back to the relative values, because otherwise one (size) may overwhelm the other (rowCount). But this time we avoid adding up the ratios.

Originally `A.betterThan(B) => w*relativeRows + (1-w)*relativeSize < 1` was used. Besides being "non-symteric", this also can exhibit one overwhelming other.
For `w=0.5` If `A` size (bytes) is at least 2x larger than `B`, then no matter how many times more rows does the `B` plan have, `B` will allways be considered to be better - `0.5*2 + 0.5*0.00000000000001 > 1`.

When working with ratios, then it would be better to multiply them.
The proposed cost comparison function is: `A.betterThan(B) => relativeRows^w  * relativeSize^(1-w) < 1`.

### Does this PR introduce _any_ user-facing change?

Comparison of the changed TPCDS v1.4 query execution times at sf=10:

  | absolute | multiplicative |   | additive |  
-- | -- | -- | -- | -- | --
q12 | 145 | 137 | -5.52% | 141 | -2.76%
q13 | 264 | 271 | 2.65% | 271 | 2.65%
q17 | 4521 | 4243 | -6.15% | 4348 | -3.83%
q18 | 758 | 466 | -38.52% | 480 | -36.68%
q19 | 38503 | 2167 | -94.37% | 2176 | -94.35%
q20 | 119 | 120 | 0.84% | 126 | 5.88%
q24a | 16429 | 16838 | 2.49% | 17103 | 4.10%
q24b | 16592 | 16999 | 2.45% | 17268 | 4.07%
q25 | 3558 | 3556 | -0.06% | 3675 | 3.29%
q33 | 362 | 361 | -0.28% | 380 | 4.97%
q52 | 1020 | 1032 | 1.18% | 1052 | 3.14%
q55 | 927 | 938 | 1.19% | 961 | 3.67%
q72 | 24169 | 13377 | -44.65% | 24306 | 0.57%
q81 | 1285 | 1185 | -7.78% | 1168 | -9.11%
q91 | 324 | 336 | 3.70% | 337 | 4.01%
q98 | 126 | 129 | 2.38% | 131 | 3.97%

All times are in ms, the change is compared to the situation in the master branch (absolute).
The proposed cost function (multiplicative) significantlly improves the performance on q18, q19 and q72. The original cost function (additive) has similar improvements at q18 and q19. All other chagnes are within the error bars and I would ignore them - perhaps q81 has also improved.

Karen Feng 3b634f66c3 [SPARK-34923][SQL] Metadata output should be empty for more plans
### What changes were proposed in this pull request?

Changes the metadata propagation framework.

Previously, most `LogicalPlan`'s propagated their `children`'s `metadataOutput`. This did not make sense in cases where the `LogicalPlan` did not even propagate their `children`'s `output`.

I set the metadata output for plans that do not propagate their `children`'s `output` to be `Nil`. Notably, `Project` and `View` no longer have metadata output.

### Why are the changes needed?

Previously, `SELECT m from (SELECT a from tb)` would output `m` if it were metadata. This did not make sense.

### Does this PR introduce _any_ user-facing change?

Yes. Now, `SELECT m from (SELECT a from tb)` will encounter an `AnalysisException`.

### How was this patch tested?

Added unit tests. I did not cover all cases, as they are fairly extensive. However, the new tests cover major cases (and an existing test already covers Join).

Wenchen Fan 39d5677ee3 [SPARK-34932][SQL] deprecate GROUP BY ... GROUPING SETS (...) and promote GROUP BY GROUPING SETS (...)
### What changes were proposed in this pull request?

GROUP BY ... GROUPING SETS (...) is a weird SQL syntax we copied from Hive. It's not in the SQL standard or any other mainstream databases. This syntax requires users to repeat the expressions inside `GROUPING SETS (...)` after `GROUP BY`, and has a weird null semantic if `GROUP BY` contains extra expressions than `GROUPING SETS (...)`.

This PR deprecates this syntax:
1. Do not promote it in the document and only mention it as a Hive compatible sytax.
2. Simplify the code to only keep it for Hive compatibility.

### Why are the changes needed?

Deprecate a weird grammar.

### Does this PR introduce _any_ user-facing change?

No breaking change, but it removes a check to simplify the code: `GROUP BY a GROUPING SETS(a, b)` fails before and forces users to also put `b` after `GROUP BY`. Now this works just as `GROUP BY GROUPING SETS(a, b)`.

HyukjinKwon ebf01ec3c1 [SPARK-34950][TESTS] Update benchmark results to the ones created by GitHub Actions machines
### What changes were proposed in this pull request?

https://github.com/apache/spark/pull/32015 added a way to run benchmarks much more easily in the same GitHub Actions build. This PR updates the benchmark results by using the way.

**NOTE** that looks like GitHub Actions use four types of CPU given my observations:

- Intel(R) Xeon(R) Platinum 8171M CPU  2.60GHz
- Intel(R) Xeon(R) CPU E5-2673 v4  2.30GHz
- Intel(R) Xeon(R) CPU E5-2673 v3  2.40GHz
- Intel(R) Xeon(R) Platinum 8272CL CPU  2.60GHz

Given my quick research, seems like they perform roughly similarly:

![Screen Shot 2021-04-03 at 9 31 23 PM](https://user-images.githubusercontent.com/6477701/113478478-f4b57b80-94c3-11eb-9047-f81ca8c59672.png)

I couldn't find enough information about Intel(R) Xeon(R) Platinum 8272CL CPU  2.60GHz but the performance seems roughly similar given the numbers.

So shouldn't be a big deal especially given that this way is much easier, encourages contributors to run more and guarantee the same number of cores and same memory with the same softwares.

### Why are the changes needed?

To have a base line of the benchmarks accordingly.

### Does this PR introduce _any_ user-facing change?

No, dev-only.

### How was this patch tested?

It was generated from:

yi.wu f897cc2374 [SPARK-34354][SQL] Fix failure when apply CostBasedJoinReorder on self-join
### What changes were proposed in this pull request?

This PR introduces a new analysis rule `DeduplicateRelations`, which deduplicates any duplicate relations in a plan first and then deduplicates conflicting attributes(which resued the `dedupRight` of `ResolveReferences`).

### Why are the changes needed?

`CostBasedJoinReorder` could fail when applying on self-join, e.g.,

```scala
// test in JoinReorderSuite
test("join reorder with self-join") {
  val plan = t2.join(t1, Inner, Some(nameToAttr("t1.k-1-2") === nameToAttr("t2.k-1-5")))
      .select(nameToAttr("t1.v-1-10"))
      .join(t2, Inner, Some(nameToAttr("t1.v-1-10") === nameToAttr("t2.k-1-5")))

    // this can fail
    Optimize.execute(plan.analyze)
}
```
Besides, with the new rule `DeduplicateRelations`, we'd be able to enable some optimizations, e.g., LeftSemiAnti pushdown, redundant project removal, as reflects in updated unit tests.

### Does this PR introduce _any_ user-facing change?

### How was this patch tested?

Added and updated unit tests.

Cheng Su 1fc66f6870 [SPARK-34862][SQL] Support nested column in ORC vectorized reader
### What changes were proposed in this pull request?

This PR is to support nested column type in Spark ORC vectorized reader. Currently ORC vectorized reader [does not support nested column type (struct, array and map)](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/orc/OrcFileFormat.scala#L138). We implemented nested column vectorized reader for FB-ORC in our internal fork of Spark. We are seeing performance improvement compared to non-vectorized reader when reading nested columns. In addition, this can also help improve the non-nested column performance when reading non-nested and nested columns together in one query.

Before this PR:

* `OrcColumnVector` is the implementation class for Spark's `ColumnVector` to wrap Hive's/ORC's `ColumnVector` to read `AtomicType` data.

After this PR:

* `OrcColumnVector` is an abstract class to keep interface being shared between multiple implementation class of orc column vectors, namely `OrcAtomicColumnVector` (for `AtomicType`), `OrcArrayColumnVector` (for `ArrayType`), `OrcMapColumnVector` (for `MapType`), `OrcStructColumnVector` (for `StructType`). So the original logic to read `AtomicType` data is moved from `OrcColumnVector` to `OrcAtomicColumnVector`. The abstract class of `OrcColumnVector` is needed here because of supporting nested column (i.e. nested column vectors).
* A utility method `OrcColumnVectorUtils.toOrcColumnVector` is added to create Spark's `OrcColumnVector` from Hive's/ORC's `ColumnVector`.
* A new user-facing config `spark.sql.orc.enableNestedColumnVectorizedReader` is added to control enabling/disabling vectorized reader for nested columns. The default value is false (i.e. disabling by default). For certain tables having deep nested columns, vectorized reader might take too much memory for each sub-column vectors, compared to non-vectorized reader. So providing a config here to work around OOM for query reading wide and deep nested columns if any. We plan to enable it by default on 3.3. Leave it disable in 3.2 in case for any unknown bugs.

### Why are the changes needed?

Improve query performance when reading nested columns from ORC file format.
Tested with locally adding a small benchmark in `OrcReadBenchmark.scala`. Seeing more than 1x run time improvement.

Gengliang Wang 3951e3371a [SPARK-34881][SQL] New SQL Function: TRY_CAST
### What changes were proposed in this pull request?

Add a new SQL function `try_cast`.
`try_cast` is identical to  `AnsiCast` (or `Cast` when `spark.sql.ansi.enabled` is true), except it returns NULL instead of raising an error.
This expression has one major difference from `cast` with `spark.sql.ansi.enabled` as true: when the source value can't be stored in the target integral(Byte/Short/Int/Long) type, `try_cast` returns null instead of returning the low order bytes of the source value.
Note that the result of `try_cast` is not affected by the configuration `spark.sql.ansi.enabled`.

This is learned from Google BigQuery and Snowflake:
https://docs.snowflake.com/en/sql-reference/functions/try_cast.html
https://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#safe_casting

### Why are the changes needed?

This is an useful for the following scenarios:
1. When ANSI mode is on, users can choose `try_cast` an alternative way to run SQL without errors for certain operations.
2. When ANSI mode is off, users can use `try_cast` to get a more reasonable result for casting a value to an integral type: when an overflow error happens, `try_cast` returns null while `cast` returns the low order bytes of the source value.

### Does this PR introduce _any_ user-facing change?

Yes, adding a new function `try_cast`

### How was this patch tested?

Unit tests.

yi.wu f05b940749 [SPARK-34354][SQL] Fix failure when apply CostBasedJoinReorder on self-join
### What changes were proposed in this pull request?

This PR introduces a new analysis rule `DeduplicateRelations`, which deduplicates any duplicate relations in a plan first and then deduplicates conflicting attributes(which resued the `dedupRight` of `ResolveReferences`).

### Why are the changes needed?

`CostBasedJoinReorder` could fail when applying on self-join, e.g.,

```scala
// test in JoinReorderSuite
test("join reorder with self-join") {
  val plan = t2.join(t1, Inner, Some(nameToAttr("t1.k-1-2") === nameToAttr("t2.k-1-5")))
      .select(nameToAttr("t1.v-1-10"))
      .join(t2, Inner, Some(nameToAttr("t1.v-1-10") === nameToAttr("t2.k-1-5")))

    // this can fail
    Optimize.execute(plan.analyze)
}
```
Besides, with the new rule `DeduplicateRelations`, we'd be able to enable some optimizations, e.g., LeftSemiAnti pushdown, redundant project removal, as reflects in updated unit tests.

### Does this PR introduce _any_ user-facing change?

Ali Afroozeh bd0990e3e8 [SPARK-34906] Refactor TreeNode's children handling methods into specialized traits
### What changes were proposed in this pull request?
Spark query plan node hierarchy has specialized traits (or abstract classes) for handling nodes with fixed number of children, for example `UnaryExpression`, `UnaryNode` and `UnaryExec` for representing an expression, a logical plan and a physical plan with only one child, respectively. This PR refactors the `TreeNode` hierarchy by extracting the children handling functionality into the following traits. `UnaryExpression` and other similar classes now extend the corresponding new trait:
```
trait LeafLike[T <: TreeNode[T]] { self: TreeNode[T] =>
  override final def children: Seq[T] = Nil
}

trait UnaryLike[T <: TreeNode[T]] { self: TreeNode[T] =>
  def child: T
  transient override final lazy val children: Seq[T] = child :: Nil
}

trait BinaryLike[T <: TreeNode[T]] { self: TreeNode[T] =>
  def left: T
  def right: T
  transient override final lazy val children: Seq[T] = left :: right :: Nil
}

trait TernaryLike[T <: TreeNode[T]] { self: TreeNode[T] =>
  def first: T
  def second: T
  def third: T
  transient override final lazy val children: Seq[T] = first :: second :: third :: Nil
}
```

This refactoring, which is part of a bigger effort to make tree transformations in Spark more efficient, has two benefits:
- It moves the children handling methods to a single place, instead of being spread in specific subclasses, which will help the future optimizations for tree traversals.
- It allows to mix in these traits with some concrete node types that could not extend the previous classes. For example, expressions with one child that extend `AggregateFunction` cannot extend `UnaryExpression` as `AggregateFunction` defines the `foldable` method final while `UnaryExpression` defines it as non final. With the new traits, we can directly extend the concrete class from `UnaryLike` in these cases. Classes with more specific child handling will make tree traversal methods faster.

In this PR we have also updated many concrete node types to extend these traits to benefit from more specific child handling.

### Why are the changes needed?

### Does this PR introduce _any_ user-facing change?

### How was this patch tested?

This is a refactoring, passes existing tests.

angerszhu a98dc60408 [SPARK-33308][SQL] Refactor current grouping analytics
### What changes were proposed in this pull request?
As discussed in
https://github.com/apache/spark/pull/30145#discussion_r514728642
https://github.com/apache/spark/pull/30145#discussion_r514734648

We need to rewrite current Grouping Analytics grammar to support  as flexible as Postgres SQL to support subsequent development.
In  postgres sql, it support
```
select a, b, c, count(1) from t group by cube (a, b, c);
select a, b, c, count(1) from t group by cube(a, b, c);
select a, b, c, count(1) from t group by cube (a, b, c, (a, b), (a, b, c));
select a, b, c, count(1) from t group by rollup(a, b, c);
select a, b, c, count(1) from t group by rollup (a, b, c);
select a, b, c, count(1) from t group by rollup (a, b, c, (a, b), (a, b, c));
```
In this pr,  we have done three things as below, and we will split it to different pr:

 - Refactor CUBE/ROLLUP (regarding them as ANTLR tokens in a parser)
 - Refactor GROUPING SETS (the logical node -> a new expr)
 - Support new syntax for CUBE/ROLLUP (e.g., GROUP BY CUBE ((a, b), (a, c)))

### Why are the changes needed?
Rewrite current Grouping Analytics grammar to support  as flexible as Postgres SQL to support subsequent development.

### Does this PR introduce _any_ user-facing change?
User can  write Grouping Analytics grammar as flexible as Postgres SQL to support subsequent development.

### How was this patch tested?

Some `spark-submit`  commands used to run benchmarks in the user's guide is wrong, we can't use these commands to run benchmarks successful.

So the major changes of this pr is correct these wrong commands, for example, run a benchmark which inherits from `SqlBasedBenchmark`, we must specify `--jars <spark core test jar>,<spark catalyst test jar>` because `SqlBasedBenchmark` based benchmark extends `BenchmarkBase(defined in spark core test jar)` and `SQLHelper(defined in spark catalyst test jar)`.

Another change of this pr is removed the `scalatest Assertions` dependency of Benchmarks because `scalatest-*.jar` are not in the distribution package, it will be troublesome to use.

Jungtaek Lim 43e08b1f0f [SPARK-34255][SQL] Support partitioning with static number on required distribution and ordering on V2 write
### What changes were proposed in this pull request?

This PR proposes to extend the functionality of requirement for distribution and ordering on V2 write to specify the number of partitioning on repartition, so that data source is able to control the parallelism and determine the data distribution per partition in prior.

The partitioning with static number is optional, and by default disabled via default method, so only implementations required to restrict the number of partition statically need to override the method and provide the number.

Note that we don't support static number of partitions with unspecified distribution for this PR, as we haven't found the real use cases, and for hypothetical case the static number isn't good enough. Javadoc clearly describes the limitation.

### Why are the changes needed?

The use case comes from feature parity with DSv1.

I have state data source which enables the state in SS to be rewritten, which enables repartitioning, schema evolution, etc via batch query. The writer requires hash partitioning against group key, with the "desired number of partitions", which is same as what Spark does read and write against state.

This is now implemented as DSv1, and the requirement is simply done by calling repartition with the "desired number".

```
val fullPathsForKeyColumns = keySchema.map(key => new Column(s"key.${key.name}"))
data
  .repartition(newPartitions, fullPathsForKeyColumns: _*)
  .queryExecution
  .toRdd
  .foreachPartition(
    writeFn(resolvedCpLocation, version, operatorId, storeName, keySchema, valueSchema,
      storeConf, hadoopConfBroadcast, queryId))
```

Thanks to SPARK-34026, it's now possible to require the hash partitioning, but still not able to require the number of partitions. This PR will enable to let data source require the number of partitions.

### Does this PR introduce _any_ user-facing change?

Yes, but only for data source implementors. Even for them, this is no breaking change as default method is added.

### How was this patch tested?

Added UTs.

Tanel Kiis 4b9e94c444 [SPARK-34876][SQL] Fill defaultResult of non-nullable aggregates
### What changes were proposed in this pull request?

Filled the `defaultResult` field on non-nullable aggregates

### Why are the changes needed?

The `defaultResult` defaults to `None` and in some situations (like correlated scalar subqueries) it is used for the value of the aggregation.

The UT result before the fix:
```

Gengliang Wang 0515f49018 [SPARK-34856][SQL] ANSI mode: Allow casting complex types as string type
### What changes were proposed in this pull request?

Allow casting complex types as string type in ANSI mode.

### Why are the changes needed?

Currently, complex types are not allowed to cast as string type. This breaks the DataFrame.show() API. E.g
```
scala> sql(“select array(1, 2, 2)“).show(false)
org.apache.spark.sql.AnalysisException: cannot resolve ‘CAST(`array(1, 2, 2)` AS STRING)’ due to data type mismatch:
 cannot cast array<int> to string with ANSI mode on.
```
We should allow the conversion as the extension of the ANSI SQL standard, so that the DataFrame.show() still work in ANSI mode.
### Does this PR introduce _any_ user-facing change?

Yes, casting complex types as string type is now allowed in ANSI mode.

### How was this patch tested?

Takeshi Yamamuro 150769bced [SPARK-34833][SQL] Apply right-padding correctly for correlated subqueries
### What changes were proposed in this pull request?

This PR intends to fix the bug that does not apply right-padding for char types inside correlated subquries.
For example,  a query below returns nothing in master, but a correct result is `c`.
```
scala> sql(s"CREATE TABLE t1(v VARCHAR(3), c CHAR(5)) USING parquet")
scala> sql(s"CREATE TABLE t2(v VARCHAR(5), c CHAR(7)) USING parquet")
scala> sql("INSERT INTO t1 VALUES ('c', 'b')")
scala> sql("INSERT INTO t2 VALUES ('a', 'b')")
scala> val df = sql("""
  |SELECT v FROM t1
  |WHERE 'a' IN (SELECT v FROM t2 WHERE t2.c = t1.c )""".stripMargin)

scala> df.show()
+---+
|  v|
+---+
+---+

```

This is because `ApplyCharTypePadding`  does not handle the case above to apply right-padding into `'abc'`. This PR modifies the code in `ApplyCharTypePadding` for handling it correctly.

```
// Before this PR:
scala> df.explain(true)

In ANSI mode, we can make the behavior more reasonable by returning the closet convertible data type in `TypeCollection`.

In details, we first try to find the all the expected types we can implicitly cast:
1. if there is no convertible data types, return None;
2. if there is only one convertible data type, cast input as it;
3. otherwise if there are multiple convertible data types, find the closet data
type among them. If there is no such closet data type, return None.

Note that if the closet type is Float type and the convertible types contains Double type, simply return Double type as the closet type to avoid potential
precision loss on converting the Integral type as Float type.

### Why are the changes needed?

Make the type coercion rule for TypeCollection more reasonable and ANSI compatible.
E.g. returning Long instead of Double for`implicast(int, TypeCollect(Double, Long))`.

### Does this PR introduce _any_ user-facing change?

Yes, in ANSI mode, implicit casting to a `TypeCollection` returns the narrowest convertible data type instead of the first convertible one.

Kousuke Saruta f7e9b6efc7 [SPARK-34763][SQL] col(), $"<name>" and df("name") should handle quoted column names properly
### What changes were proposed in this pull request?

This PR fixes an issue that `col()`, `$"<name>"` and `df("name")` don't handle quoted column names  like ``` `a``b.c` ```properly.

For example, if we have a following DataFrame.
```
val df1 = spark.sql("SELECT 'col1' AS `a``b.c`")
```

For the DataFrame, this query is successfully executed.
```
scala> df1.selectExpr("`a``b.c`").show
+-----+
|a`b.c|
+-----+
| col1|
+-----+
```

But the following query will fail because ``` df1("`a``b.c`") ``` throws an exception.
```
scala> df1.select(df1("`a``b.c`")).show

Wenchen Fan 3b70829b5b [SPARK-34719][SQL] Correctly resolve the view query with duplicated column names
forward-port https://github.com/apache/spark/pull/31811 to master

### What changes were proposed in this pull request?

For permanent views (and the new SQL temp view in Spark 3.1), we store the view SQL text and re-parse/analyze the view SQL text when reading the view. In the case of `SELECT * FROM ...`, we want to avoid view schema change (e.g. the referenced table changes its schema) and will record the view query output column names when creating the view, so that when reading the view we can add a `SELECT recorded_column_names FROM ...` to retain the original view query schema.

In Spark 3.1 and before, the final SELECT is added after the analysis phase: https://github.com/apache/spark/blob/branch-3.1/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/view.scala#L67

If the view query has duplicated output column names, we always pick the first column when reading a view. A simple repro:
```
scala> sql("create view c(x, y) as select 1 a, 2 a")
res0: org.apache.spark.sql.DataFrame = []

scala> sql("select * from c").show
+---+---+
|  x|  y|
+---+---+
|  1|  1|
+---+---+
```

In the master branch, we will fail at the view reading time due to b891862fb6 , which adds the final SELECT during analysis, so that the query fails with `Reference 'a' is ambiguous`

This PR proposes to resolve the view query output column names from the matching attributes by ordinal.

For example,  `create view c(x, y) as select 1 a, 2 a`, the view query output column names are `[a, a]`. When we reading the view, there are 2 matching attributes (e.g.`[a#1, a#2]`) and we can simply match them by ordinal.

A negative example is
```
create table t(a int)
create view v as select *, 1 as col from t
replace table t(a int, col int)
```
When reading the view, the view query output column names are `[a, col]`, and there are two matching attributes of `col`, and we should fail the query. See the tests for details.

### Why are the changes needed?

bug fix

### Does this PR introduce _any_ user-facing change?

yes

Liang-Chi Hsieh 115ed89a3c [SPARK-34366][SQL] Add interface for DS v2 metrics
### What changes were proposed in this pull request?

This patch proposes to add a few public API change to DS v2, to make DS v2 scan can report metrics to Spark.

Two public interfaces are added.

* `CustomMetric`: metric interface at the driver side. It basically defines how Spark aggregates task metrics with the same metric name.
* `CustomTaskMetric`: task metric reported at executors. It includes a name and long value. Spark will collect these metric values and update internal metrics.

There are two public methods added to existing public interfaces. They are optional to DS v2 implementations.

* `PartitionReader.currentMetricsValues()`: returns an array of CustomTaskMetric. Here is where the actual metrics values are collected. Empty array by default.
* `Scan.supportedCustomMetrics()`: returns an array of supported custom metrics `CustomMetric`. Empty array by default.

### Why are the changes needed?

In order to report custom metrics, we need some public API change in DS v2 to make it possible.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

This only adds interfaces. In follow-up PRs where adding implementation there will be tests added. See #31451 and #31398 for some details and manual test there.

### What changes were proposed in this pull request?

This patch proposes to disable fetching shuffle blocks in batch when io encryption is enabled. Adaptive Query Execution fetch contiguous shuffle blocks for the same map task in batch to reduce IO and improve performance. However, we found that batch fetching is incompatible with io encryption.

yi.wu e4bb97526c [SPARK-34089][CORE] HybridRowQueue should respect the configured memory mode
### What changes were proposed in this pull request?

This PR fixes the `HybridRowQueue ` to respect the configured memory mode.

Besides, this PR also refactored the constructor of `MemoryConsumer` to accept the memory mode explicitly.

### Why are the changes needed?

`HybridRowQueue` supports both onHeap and offHeap manipulation. But it inherited the wrong `MemoryConsumer` constructor, which hard-coded the memory mode to `onHeap`.

### Does this PR introduce _any_ user-facing change?

No. (Maybe yes in some cases where users can't complete the job before could complete successfully after the fix because of `HybridRowQueue` is able to spill under offHeap mode now. )

Max Gekk 089c3b77e1 [SPARK-34793][SQL] Prohibit saving of day-time and year-month intervals
### What changes were proposed in this pull request?
For all built-in datasources, prohibit saving of year-month and day-time intervals that were introduced by SPARK-27793. We plan to support saving of such types at the milestone 2, see SPARK-27790.

### Why are the changes needed?
To improve user experience with Spark SQL, and print nicer error message. Current error message might confuse users:
```

org.apache.spark.sql.AnalysisException: Cannot save interval data type into external storage.
```

### How was this patch tested?
1. Checked nested intervals:
```
scala> spark.range(1).selectExpr("""struct(timestamp'2021-01-02 00:01:02' - timestamp'2021-01-01 00:00:00')""").write.mode("overwrite").parquet("/Users/maximgekk/tmp/123")
org.apache.spark.sql.AnalysisException: Cannot save interval data type into external storage.
scala> Seq(Seq(java.time.Period.ofMonths(1))).toDF.write.mode("overwrite").json("/Users/maximgekk/tmp/123")
org.apache.spark.sql.AnalysisException: Cannot save interval data type into external storage.
```
2. By running existing test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *DataSourceV2DataFrameSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *DataSourceV2SQLSuite"

ulysses-you 58509565f8 [SPARK-34772][SQL] RebaseDateTime loadRebaseRecords should use Spark classloader instead of context
### What changes were proposed in this pull request?

Change context classloader to Spark classloader at `RebaseDateTime.loadRebaseRecords`

### Why are the changes needed?

With custom `spark.sql.hive.metastore.version` and `spark.sql.hive.metastore.jars`.

Spark would use date formatter in `HiveShim` that convert `date` to `string`, if we set `spark.sql.legacy.timeParserPolicy=LEGACY` and the partition type is `date` the `RebaseDateTime` code will be invoked. At that moment, if `RebaseDateTime` is initialized the first time then context class loader is `IsolatedClientLoader`. Such error msg would throw:

Max Gekk a48b2086dd [SPARK-34761][SQL] Support add/subtract of a day-time interval to/from a timestamp
### What changes were proposed in this pull request?
Support `timestamp +/- day-time interval`. In the PR, I propose to extend the `TimeAdd` expression and support `DayTimeIntervalType` as the `interval` parameter. The expression invokes the new method `DateTimeUtils.timestampAddDayTime()` which splits the input day-time interval to `days` and `microsecond adjustment` of a day, and adds `days` (and the microseconds) to a local timestamp derived from the given timestamp at the given time zone.  The resulted local timestamp is converted back to the offset in microseconds since the epoch.

Also I updated the rules that handle `CalendarIntervalType` and produce `TimeAdd` to take into account new type `DateTimeIntervalType` for the `interval` parameter of `TimeAdd`.

### Why are the changes needed?
To conform the ANSI SQL standard which requires to support such operation over timestamps and intervals:

### Does this PR introduce _any_ user-facing change?
Should not since new intervals have not been released yet.

### What changes were proposed in this pull request?

This PR proposes to deduplicate the source table when there're conflicting attributes between the target table and the source table.

### Why are the changes needed?

When resolving the `UpdateAction`, which could reference attributes from both target and source tables,  Spark should know clearly where the attribute comes from when there're conflicting attributes instead of picking up a random one.

### Does this PR introduce _any_ user-facing change?

No.

### What changes were proposed in this pull request?

Push down limit through `Window` when the partitionSpec of all window functions is empty and the same order is used. This is a real case from production:

![image](https://user-images.githubusercontent.com/5399861/109457143-3900c680-7a95-11eb-9078-806b041175c2.png)

This pr support 2 cases:
1. All window functions have same orderSpec:
   ```sql
   SELECT *, ROW_NUMBER() OVER(ORDER BY a) AS rn, RANK() OVER(ORDER BY a) AS rk FROM t1 LIMIT 5;
   == Optimized Logical Plan ==
   Window [row_number() windowspecdefinition(a#9L ASC NULLS FIRST, specifiedwindowframe(RowFrame,          unboundedpreceding$(), currentrow$())) AS rn#4, rank(a#9L) windowspecdefinition(a#9L ASC NULLS FIRST, specifiedwindowframe(RowFrame, unboundedpreceding$(), currentrow$())) AS rk#5], [a#9L ASC NULLS FIRST]
   +- GlobalLimit 5
      +- LocalLimit 5
         +- Sort [a#9L ASC NULLS FIRST], true
            +- Relation default.t1[A#9L,B#10L,C#11L] parquet
   ```
2. There is a window function with a different orderSpec:
   ```sql
   SELECT a, ROW_NUMBER() OVER(ORDER BY a) AS rn, RANK() OVER(ORDER BY b DESC) AS rk FROM t1 LIMIT 5;
   == Optimized Logical Plan ==
   Project [a#9L, rn#4, rk#5]
   +- Window [rank(b#10L) windowspecdefinition(b#10L DESC NULLS LAST, specifiedwindowframe(RowFrame, unboundedpreceding$(), currentrow$())) AS rk#5], [b#10L DESC NULLS LAST]
      +- GlobalLimit 5
         +- LocalLimit 5
            +- Sort [b#10L DESC NULLS LAST], true
               +- Window [row_number() windowspecdefinition(a#9L ASC NULLS FIRST, specifiedwindowframe(RowFrame, unboundedpreceding$(), currentrow$())) AS rn#4], [a#9L ASC NULLS FIRST]
                  +- Project [a#9L, b#10L]
                     +- Relation default.t1[A#9L,B#10L,C#11L] parquet
   ```

### Why are the changes needed?

Improve query performance.

```scala
spark.range(500000000L).selectExpr("id AS a", "id AS b").write.saveAsTable("t1")
spark.sql("SELECT *, ROW_NUMBER() OVER(ORDER BY a) AS rowId FROM t1 LIMIT 5").show

Max Gekk 9809a2f1c5 [SPARK-34739][SQL] Support add/subtract of a year-month interval to/from a timestamp
### What changes were proposed in this pull request?
Support `timestamp +/- year-month interval`. In the PR, I propose to introduce new binary expression `TimestampAddYMInterval` similarly to `DateAddYMInterval`. It invokes new method `timestampAddMonths` from `DateTimeUtils` by passing a timestamp as an offset in microseconds since the epoch, amount of months from the giveb year-month interval, and the time zone ID in which the operation is performed. The `timestampAddMonths()` method converts the input microseconds to a local timestamp, adds months to it, and converts the results back to an instant in microseconds at the given time zone.

### Why are the changes needed?
To conform the ANSI SQL standard which requires to support such operation over timestamps and intervals:

### Does this PR introduce _any_ user-facing change?

This PR aims to make `ExpressionEncoderSuite` to use `deepEquals` instead of `equals` when `input` is `array of array`.

This comparison code itself was added by SPARK-11727 at Apache Spark 1.6.0.

### Why are the changes needed?

Currently, the interpreted mode fails for `array of array` because the following line is used.
```
Arrays.equals(b1.asInstanceOf[Array[AnyRef]], b2.asInstanceOf[Array[AnyRef]])
```

### Does this PR introduce _any_ user-facing change?

No. This is a test-only PR.

### How was this patch tested?

Pass the existing CIs.

Closes #31837 from dongjoon-hyun/SPARK-34743.

Max Gekk 7aaed76125 [SPARK-34737][SQL] Cast input float to double in TIMESTAMP_SECONDS
### What changes were proposed in this pull request?
In the PR, I propose to cast the input float to double in the `SecondsToTimestamp` expression in the same way as in the `Cast` expression.

### Why are the changes needed?
To have the same results from `CAST(<float> AS TIMESTAMP)` and from `TIMESTAMP_SECONDS`:
```sql
spark-sql> SELECT CAST(16777215.0f AS TIMESTAMP);
1970-07-14 07:20:15
spark-sql> SELECT TIMESTAMP_SECONDS(16777215.0f);
1970-07-14 07:20:14.951424
```

### Does this PR introduce _any_ user-facing change?
Yes. After the changes:
```sql
spark-sql> SELECT TIMESTAMP_SECONDS(16777215.0f);
1970-07-14 07:20:15
```

### How was this patch tested?
By running new test:
```
$ build/sbt "test:testOnly *DateExpressionsSuite"
```

Max Gekk e0a1399bd7 [SPARK-34727][SQL] Fix discrepancy in casting float to timestamp
### What changes were proposed in this pull request?
In non-ANSI mode, casting float to timestamp has different implementation for codegen on and off.

Codegen on:
1. Multiply float input by MICROS_PER_SECOND
2. Cast resulting float value to long

Codegen off:
1. CAST float input to double input
2. Multiply double input by MICROS_PER_SECOND
3. Cast resulting double value to long

In the PR, I propose to align to non-codegen code, and cast input float to double in codegen.

### Why are the changes needed?
This fixes the issue which is demonstrated by the code:
```sql
spark-sql> CREATE TEMP VIEW v1 AS SELECT 16777215.0f AS f;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:15
spark-sql> CACHE TABLE v1;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:14.951424
```
The result from the cached view **1970-07-14 07:20:14.951424** is different from un-cached view **1970-07-14 07:20:15**.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above outputs the same timestamp for the cached view:
```sql
spark-sql> CACHE TABLE v1;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:15
```

### How was this patch tested?
By running new test:
```
$ build/sbt "test:testOnly *CastSuite"
```

Liang-Chi Hsieh 86baa36eeb [SPARK-34723][SQL] Correct parameter type for subexpression elimination under whole-stage
### What changes were proposed in this pull request?

This patch proposes to fix incorrect parameter type for subexpression elimination under whole-stage.

### Why are the changes needed?

If the parameter is a byte array, the subexpression elimination under wholestage codegen will use incorrect parameter type and cause compile error. Although Spark can automatically fallback to interpreted mode, we should fix it.

### What changes were proposed in this pull request?

Dongjoon Hyun 9a7977933f [SPARK-34724][SQL] Fix Interpreted evaluation by using getMethod instead of getDeclaredMethod
### What changes were proposed in this pull request?

This bug was introduced by SPARK-23583 at Apache Spark 2.4.0.

This PR aims to use `getMethod` instead of `getDeclaredMethod`.
```scala
- obj.getClass.getDeclaredMethod(functionName, argClasses: _*)
+ obj.getClass.getMethod(functionName, argClasses: _*)
```

### Why are the changes needed?

`getDeclaredMethod` does not search the super class's method. To invoke `GenericArrayData.toIntArray`, we need to use `getMethod` because it's declared at the super class `ArrayData`.

Max Gekk d7bb327aee [SPARK-34695][SQL] Fix long overflow in conversion of minimum duration to microseconds
### What changes were proposed in this pull request?
In the PR, I propose to especially handle the amount of seconds `-9223372036855` in `IntervalUtils. durationToMicros()`. Starting from the amount (any durations with the second field < `-9223372036855`), input durations cannot fit to `Long` in the conversion to microseconds. For example, the amount of microseconds = `Long.MinValue = -9223372036854775808` can be represented in two forms:
1. seconds = -9223372036854, nanoAdjustment = -775808, or
2. seconds = -9223372036855, nanoAdjustment = +224192

And the method `Duration.ofSeconds()` produces the last form but such form causes overflow while converting `-9223372036855` seconds to microseconds.

In the PR, I propose to convert the second form to the first one if the second field of input duration is equal to `-9223372036855`.

### Why are the changes needed?
The changes fix the issue demonstrated by the code:
```scala
scala> durationToMicros(microsToDuration(Long.MinValue))
java.lang.ArithmeticException: long overflow
  at java.lang.Math.multiplyExact(Math.java:892)
  at org.apache.spark.sql.catalyst.util.IntervalUtils$.durationToMicros(IntervalUtils.scala:782)
  ... 49 elided
```
The `durationToMicros()` method cannot handle valid output of `microsToDuration()`.

### Does this PR introduce _any_ user-facing change?
Should not since new interval types has not been released yet.

### How was this patch tested?
By running new UT from `IntervalUtilsSuite`.

ulysses-you 744a73df9e [SPARK-34538][SQL] Hive Metastore support filter by not-in
### What changes were proposed in this pull request?

Add `Not(In)` and `Not(InSet)` pattern when convert filter to metastore.

### Why are the changes needed?

`NOT IN` is a useful condition to prune partition, it would be better to support it.

Technically, we can convert `c not in(x,y)` to `c != x and c != y`, then push it to metastore.

Avoid metastore overflow and respect the config `spark.sql.hive.metastorePartitionPruningInSetThreshold`, `Not(InSet)` won't push to metastore if it's value exceeds the threshold.

No.

Dongjoon Hyun 5c4d8f9538 [SPARK-34696][SQL][TESTS] Fix CodegenInterpretedPlanTest to generate correct test cases
### What changes were proposed in this pull request?

SPARK-23596 added `CodegenInterpretedPlanTest` at Apache Spark 2.4.0 in a wrong way because `withSQLConf` depends on the execution time `SQLConf.get` instead of `test` function declaration time. So, the following code executes the test twice without controlling the `CodegenObjectFactoryMode`. This PR aims to fix it correct and introduce a new function `testFallback`.

```scala
trait CodegenInterpretedPlanTest extends PlanTest {

   override protected def test(
       testName: String,
       testTags: Tag*)(testFun: => Any)(implicit pos: source.Position): Unit = {
     val codegenMode = CodegenObjectFactoryMode.CODEGEN_ONLY.toString
     val interpretedMode = CodegenObjectFactoryMode.NO_CODEGEN.toString

     withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> codegenMode) {
       super.test(testName + " (codegen path)", testTags: _*)(testFun)(pos)
     }
     withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> interpretedMode) {
       super.test(testName + " (interpreted path)", testTags: _*)(testFun)(pos)
     }
   }
 }
```

### Why are the changes needed?

1. We need to use like the following.
```scala
super.test(testName + " (codegen path)", testTags: _*)(
   withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> codegenMode) { testFun })(pos)
super.test(testName + " (interpreted path)", testTags: _*)(
   withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> interpretedMode) { testFun })(pos)
```

2. After we fix this behavior with the above code, several test cases including SPARK-34596 and SPARK-34607 fail because they didn't work at both `CODEGEN` and `INTERPRETED` mode. Those test cases only work at `FALLBACK` mode. So, inevitably, we need to introduce `testFallback`.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Pass the CIs.

### What changes were proposed in this pull request?

This PR adds a default null ordering to public `SortDirection` to match the Catalyst behavior.

### Why are the changes needed?

The SQL standard does not define the default null ordering for a sort direction. That's why it is up to a query engine to assign one. We need to standardize this in our public connector expressions to avoid ambiguity. That's why I propose to match the behavior in our Catalyst expressions.

Terry Kim 2a6e68e1f7 [SPARK-34546][SQL] AlterViewAs.query should be analyzed during the analysis phase, and AlterViewAs should invalidate the cache
### What changes were proposed in this pull request?

This PR proposes the following:
   * `AlterViewAs.query` is currently analyzed in the physical operator `AlterViewAsCommand`, but it should be analyzed during the analysis phase.
   *  When `spark.sql.legacy.storeAnalyzedPlanForView` is set to true, store `TermporaryViewRelation` which wraps the analyzed plan, similar to #31273.
   *  Try to uncache the view you are altering.

### Why are the changes needed?

Analyzing a plan should be done in the analysis phase if possible.

Not uncaching the view (existing behavior) seems like a bug since the cache may not be used again.

### Does this PR introduce _any_ user-facing change?

Yes, now the view can be uncached if it's already cached.

### How was this patch tested?

Added new tests around uncaching.

The existing tests such as `SQLViewSuite` should cover the analysis changes.

Max Gekk e10bf64769 [SPARK-34615][SQL] Support java.time.Period as an external type of the year-month interval type
### What changes were proposed in this pull request?
In the PR, I propose to extend Spark SQL API to accept [`java.time.Period`](https://docs.oracle.com/javase/8/docs/api/java/time/Period.html) as an external type of recently added new Catalyst type - `YearMonthIntervalType` (see #31614). The Java class `java.time.Period` has similar semantic to ANSI SQL year-month interval type, and it is the most suitable to be an external type for `YearMonthIntervalType`. In more details:
1. Added `PeriodConverter` which converts `java.time.Period` instances to/from internal representation of the Catalyst type `YearMonthIntervalType` (to `Int` type). The `PeriodConverter` object uses new methods of `IntervalUtils`:
    - `periodToMonths()` converts the input period to the total length in months. If this period is too large to fit `Int`, the method throws the exception `ArithmeticException`. **Note:** _the input period has "days" precision, the method just ignores the days unit._
    - `monthToPeriod()` obtains a `java.time.Period` representing a number of months.
2. Support new type `YearMonthIntervalType` in `RowEncoder` via the methods `createDeserializerForPeriod()` and `createSerializerForJavaPeriod()`.
3. Extended the Literal API to construct literals from `java.time.Period` instances.

### Why are the changes needed?
1. To allow users parallelization of `java.time.Period` collections, and construct year-month interval columns. Also to collect such columns back to the driver side.
2. This will allow to write tests in other sub-tasks of SPARK-27790.

### Does this PR introduce _any_ user-facing change?
The PR extends existing functionality. So, users can parallelize instances of the `java.time.Duration` class and collect them back:

```scala
scala> val ds = Seq(java.time.Period.ofYears(10).withMonths(2)).toDS
ds: org.apache.spark.sql.Dataset[java.time.Period] = [value: yearmonthinterval]

scala> ds.collect
res0: Array[java.time.Period] = Array(P10Y2M)
```

### How was this patch tested?
- Added a few tests to `CatalystTypeConvertersSuite` to check conversion from/to `java.time.Period`.
- Checking row encoding by new tests in `RowEncoderSuite`.
- Making literals of `YearMonthIntervalType` are tested in `LiteralExpressionSuite`.
- Check collecting by `DatasetSuite` and `JavaDatasetSuite`.
- New tests in `IntervalUtilsSuites` to check conversions `java.time.Period` <-> months.

Wenchen Fan dc78f337cb [SPARK-34609][SQL] Unify resolveExpressionBottomUp and resolveExpressionTopDown
### What changes were proposed in this pull request?

It's a bit confusing to see `resolveExpressionBottomUp` and `resolveExpressionTopDown`, which provide similar functionalities but with different tree traverse order. It turns out that the real difference between these 2 methods is: which attributes should the columns be resolved to? `resolveExpressionTopDown` resolves columns using output attributes of the plan children, `resolveExpressionBottomUp` resolves columns using output attributes of the plan itself.

This PR unifies `resolveExpressionBottomUp` and `resolveExpressionTopDown` and put the common logic in a new method, and let `resolveExpressionBottomUp` and `resolveExpressionTopDown` just call the new method. This PR also renames `resolveExpressionBottomUp` and `resolveExpressionTopDown` to make the difference clear.

```

The root cause that Kris (rednaxelafx) investigated is as follows (Kudos to Kris);

The reason why the test case above is so convoluted is in the way Scala generates the class name for nested classes. In general, Scala generates a class name for a nested class by inserting the dollar-sign ( `$` ) in between each level of class nesting. The problem is that this format can concatenate into a very long string that goes beyond certain limits, so Scala will change the class name format beyond certain length threshold.

For the example above, we can see that the first two levels of class nesting have class names that look like this:
```
org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite$OuterLevelWithVeryVeryVeryLongClassName1$
org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite$OuterLevelWithVeryVeryVeryLongClassName1$OuterLevelWithVeryVeryVeryLongClassName2$
```
If we leave out the fact that Scala uses a dollar-sign ( `$` ) suffix for the class name of the companion object, `OuterLevelWithVeryVeryVeryLongClassName1`'s full name is a prefix (substring) of `OuterLevelWithVeryVeryVeryLongClassName2`.

But if we keep going deeper into the levels of nesting, you'll find names that look like:
```
org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite$OuterLevelWithVeryVeryVeryLongClassNam$$$$2a1321b953c615695d7442b2adb1$$$$ryVeryLongClassName8$OuterLevelWithVeryVeryVeryLongClassName9$OuterLevelWithVeryVeryVeryLongClassName10$

The `java.lang.Class.isMemberClass` method is implemented in JDK8u as:
http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/tip/src/share/classes/java/lang/Class.java#l1425
```
    /**
     * Returns {code true} if and only if the underlying class
     * is a member class.
     *
     * return {code true} if and only if this class is a member class.
     * since 1.5
     */
    public boolean isMemberClass() {
        return getSimpleBinaryName() != null && !isLocalOrAnonymousClass();
    }

    /**
     * Returns the "simple binary name" of the underlying class, i.e.,
     * the binary name without the leading enclosing class name.
     * Returns {code null} if the underlying class is a top level
     * class.
     */
    private String getSimpleBinaryName() {
        Class<?> enclosingClass = getEnclosingClass();
        if (enclosingClass == null) // top level class
            return null;
        // Otherwise, strip the enclosing class' name
        try {
            return getName().substring(enclosingClass.getName().length());
        } catch (IndexOutOfBoundsException ex) {
            throw new InternalError("Malformed class name", ex);
        }
    }
```
and the problematic code is `getName().substring(enclosingClass.getName().length())` -- if a class's enclosing class's full name is *longer* than the nested class's full name, this logic would end up going out of bounds.

The bug has been fixed in JDK9 by https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8057919 , but still exists in the latest JDK8u release. So from the Spark side we'd need to do something to avoid hitting this problem.

Max Gekk cd649e7aef [SPARK-27793][SQL] Add ANSI SQL day-time and year-month interval types
### What changes were proposed in this pull request?
In the PR, I propose to extend Catalyst's type system by two new types that conform to the SQL standard (see SQL:2016, section 4.6.3):
- `DayTimeIntervalType` represents the day-time interval type,
- `YearMonthIntervalType` for SQL year-month interval type.

This PR only adds the two new DataType implementations, and there will be more PRs as sub-tasks of SPARK-27790 to completely support the new ANSI interval types.

### Why are the changes needed?
Spark as it is today supports an INTERVAL datatype. However this type is of very limited use. Existing interval values cannot be compared with any other interval values, or persisted to storage. Spark users request to either implement new or expand existing built-in functions which produce some sort of measures for elapsed time, such as `DATEDIFF()`. Rather than work around the edges to fill the potholes of the existing INTERVAL data type, I would like to propose to deliver a proper ANSI compliant INTERVAL type that can be introduced with minimal incompatibility, is comparable and thus sortable, and can be persisted in tables.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
1. By checking coding style via:
```
$ ./dev/scalastyle
$ ./dev/lint-java
```
2. Run the test for the default sizes:
```
$ build/sbt "test:testOnly *DataTypeSuite"

Kris Mok ecf4811764 [SPARK-34596][SQL] Use Utils.getSimpleName to avoid hitting Malformed class name in NewInstance.doGenCode
### What changes were proposed in this pull request?

Use `Utils.getSimpleName` to avoid hitting `Malformed class name` error in `NewInstance.doGenCode`.

### Why are the changes needed?

On older JDK versions (e.g. JDK8u), nested Scala classes may trigger `java.lang.Class.getSimpleName` to throw an `java.lang.InternalError: Malformed class name` error.
In this particular case, creating an `ExpressionEncoder` on such a nested Scala class would create a `NewInstance` expression under the hood, which will trigger the problem during codegen.

Similar to https://github.com/apache/spark/pull/29050, we should use  Spark's `Utils.getSimpleName` utility function in place of `Class.getSimpleName` to avoid hitting the issue.

There are two other occurrences of `java.lang.Class.getSimpleName` in the same file, but they're safe because they're only guaranteed to be only used on Java classes, which don't have this problem, e.g.:
```scala
    // Make a copy of the data if it's unsafe-backed
    def makeCopyIfInstanceOf(clazz: Class[_ <: Any], value: String) =
      s"$value instanceof ${clazz.getSimpleName}? ${value}.copy() : $value"
    val genFunctionValue: String = lambdaFunction.dataType match {
      case StructType(_) => makeCopyIfInstanceOf(classOf[UnsafeRow], genFunction.value)
      case ArrayType(_, _) => makeCopyIfInstanceOf(classOf[UnsafeArrayData], genFunction.value)
      case MapType(_, _, _) => makeCopyIfInstanceOf(classOf[UnsafeMapData], genFunction.value)
      case _ => genFunction.value
    }
```
The Unsafe-* family of types are all Java types, so they're okay.

### Does this PR introduce _any_ user-facing change?

Fixes a bug that throws an error when using `ExpressionEncoder` on some nested Scala types, otherwise no changes.

### How was this patch tested?

Added a test case to `org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite`. It'll fail on JDK8u before the fix, and pass after the fix.

Karen Feng 2e54d68eb9 [SPARK-34547][SQL] Only use metadata columns for resolution as last resort
### What changes were proposed in this pull request?

Today, child expressions may be resolved based on "real" or metadata output attributes. We should prefer the real attribute during resolution if one exists.

### Why are the changes needed?

Today, attempting to resolve an expression when there is a "real" output attribute and a metadata attribute with the same name results in resolution failure. This is likely unexpected, as the user may not know about the metadata attribute.

### Does this PR introduce _any_ user-facing change?

Yes. Previously, the user would see an error message when resolving a column with the same name as a "real" output attribute and a metadata attribute as below:
```
org.apache.spark.sql.AnalysisException: Reference 'index' is ambiguous, could be: testcat.ns1.ns2.tableTwo.index, testcat.ns1.ns2.tableOne.index.; line 1 pos 71
at org.apache.spark.sql.catalyst.expressions.package$AttributeSeq.resolve(package.scala:363)
at org.apache.spark.sql.catalyst.plans.logical.LogicalPlan.resolveChildren(LogicalPlan.scala:107)
```

Now, resolution succeeds and provides the "real" output attribute.

### How was this patch tested?

Added a unit test.

Richard Penney 7d0743b493 [SPARK-33678][SQL] Product aggregation function
### Why is this change being proposed?
This patch adds support for a new "product" aggregation function in `sql.functions` which multiplies-together all values in an aggregation group.

This is likely to be useful in statistical applications which involve combining probabilities, or financial applications that involve combining cumulative interest rates, but is also a versatile mathematical operation of similar status to `sum` or `stddev`. Other users [have noted](https://stackoverflow.com/questions/52991640/cumulative-product-in-spark) the absence of such a function in current releases of Spark.

This function is both much more concise than an expression of the form `exp(sum(log(...)))`, and avoids awkward edge-cases associated with some values being zero or negative, as well as being less computationally costly.

### Does this PR introduce _any_ user-facing change?
No - only adds new function.

### How was this patch tested?
Built-in tests have been added for the new `catalyst.expressions.aggregate.Product` class and its invocation via the (scala) `sql.functions.product` function. The latter, and the PySpark wrapper have also been manually tested in spark-shell and pyspark sessions. The SparkR wrapper is currently untested, and may need separate validation (I'm not an "R" user myself).

An illustration of the new functionality, within PySpark is as follows:
```
import pyspark.sql.functions as pf, pyspark.sql.window as pw

df = sqlContext.range(1, 17).toDF("x")
win = pw.Window.partitionBy(pf.lit(1)).orderBy(pf.col("x"))

df.withColumn("factorial", pf.product("x").over(win)).show(20, False)

Gabriele Nizzoli b13a4b85d4 [SPARK-34573][SQL] Avoid global locking in SQLConf object for sqlConfEntries map
### What changes were proposed in this pull request?
In the `SQLConf` object, the `sqlConfEntries` map is globally synchronized (it is a Java `Collections.synchronizedMap`): any operation, including a get, will need to acquire the lock.

An example of this is calling the `DatatType.sameType` method. This will trigger a check on `SQLConf.get.caseSensitiveAnalysis`. So every time we compare two datatypes with sameType, we hit a lock.

To avoid having multiple tasks locking on this, a better approach would be to use a map that does not lock on read (like a `ConcurrentHashMap`). This map implementation does not lock on read, and on write it only locks the map partially. The only lock that happens is on write on the same map key.

### Why are the changes needed?
Multiple tasks performing any operation that directly or indirectly trigger a query to the `SQLConf.sqlConfEntries` map, will require acquiring a global lock on that map. Something as easy as calling `DataType.sameType(...)` would be locking on the global `sqlConfEntries` lock of the `Collections.synchronizedMap`.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
No functionality change. Existing unit tests run normally.

scala> show1.join(show2).where(show1("tableName") =!= show2("tableName")).show
org.apache.spark.sql.AnalysisException: Column tableName#17 are ambiguous. It's probably because you joined several Datasets together, and some of these Datasets are the same. This column points to one of the Datasets but Spark is unable to figure out which one. Please alias the Datasets with different names via `Dataset.as` before joining them, and specify the column using qualified name, e.g. `df.as("a").join(df.as("b"), $"a.id" > $"b.id")`. You can also set spark.sql.analyzer.failAmbiguousSelfJoin to false to disable this check.

```

### Does this PR introduce _any_ user-facing change?

Shixiong Zhu 62737e140c [SPARK-34556][SQL] Checking duplicate static partition columns should respect case sensitive conf
### What changes were proposed in this pull request?

This PR makes partition spec parsing respect case sensitive conf.

### Why are the changes needed?

When parsing the partition spec, Spark will call `org.apache.spark.sql.catalyst.parser.ParserUtils.checkDuplicateKeys` to check if there are duplicate partition column names in the list. But this method is always case sensitive and doesn't detect duplicate partition column names when using different cases.

### Does this PR introduce _any_ user-facing change?

Yep. This prevents users from writing incorrect queries such as `INSERT OVERWRITE t PARTITION (c='2', C='3') VALUES (1)` when they don't enable case sensitive conf.

### How was this patch tested?

The new added test will fail without this change.

Wenchen Fan 73857cdd87 [SPARK-34524][SQL] Simplify v2 partition commands resolution
### What changes were proposed in this pull request?

This PR simplifies the resolution of v2 partition commands:
1. Add a common trait for v2 partition commands, so that we don't need to match them one by one in the rules.
2. Make partition spec an expression, so that it's easier to resolve them via tree node transformation.
3. Add `TruncatePartition` so that `TruncateTable` doesn't need to be a v2 partition command.
4. Simplify `CheckAnalysis` to only check if the table is partitioned. For partitioned tables, partition spec is always resolved, so we don't need to check it. The `SupportsAtomicPartitionManagement` check is also done in the runtime. Since Spark eagerly executes commands, exception in runtime will also be thrown at analysis time.

### Why are the changes needed?

Cheng Su 6ef57d31cd [SPARK-34514][SQL] Push down limit for LEFT SEMI and LEFT ANTI join
### What changes were proposed in this pull request?

I found out during code review of https://github.com/apache/spark/pull/31567#discussion_r577379572, where we can push down limit to the left side of LEFT SEMI and LEFT ANTI join, if the join condition is empty.

Why it's safe to push down limit:

The semantics of LEFT SEMI join without condition:
(1). if right side is non-empty, output all rows from left side.
(2). if right side is empty, output nothing.

The semantics of LEFT ANTI join without condition:
(1). if right side is non-empty, output nothing.
(2). if right side is empty, output all rows from left side.

With the semantics of output all rows from left side or nothing (all or nothing), it's safe to push down limit to left side.
NOTE: LEFT SEMI / LEFT ANTI join with non-empty condition is not safe for limit push down, because output can be a portion of left side rows.

Reference: physical operator implementation for LEFT SEMI / LEFT ANTI join without condition - https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/BroadcastNestedLoopJoinExec.scala#L200-L204 .

### Why are the changes needed?

Better performance. Save CPU and IO for these joins, as limit being pushed down before join.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Added unit test in `LimitPushdownSuite.scala` and `SQLQuerySuite.scala`.

Closes #31630 from c21/limit-pushdown.

Terry Kim 714ff73d4a [SPARK-34152][SQL] Make CreateViewStatement.child to be LogicalPlan's children so that it's resolved in analyze phase
### What changes were proposed in this pull request?

This PR proposes to make `CreateViewStatement.child` to be `LogicalPlan`'s `children` so that it's resolved in the analyze phase.

### Why are the changes needed?

Currently, the `CreateViewStatement.child` is resolved when the create view command runs, which is inconsistent with other plan resolutions. For example, you may see the following in the physical plan:
```
== Physical Plan ==
Execute CreateViewCommand (1)
   +- CreateViewCommand (2)
         +- Project (4)
            +- UnresolvedRelation (3)
```

### Does this PR introduce _any_ user-facing change?

Yes. For the example, you will now see the resolved plan:
```
== Physical Plan ==
Execute CreateViewCommand (1)
   +- CreateViewCommand (2)
         +- Project (5)
            +- SubqueryAlias (4)
               +- LogicalRelation (3)
```

### How was this patch tested?

Gengliang Wang 5d9cfd727c [SPARK-34246][SQL] New type coercion syntax rules in ANSI mode
### What changes were proposed in this pull request?

In Spark ANSI mode, the type coercion rules are based on the type precedence lists of the input data types.
As per the section "Type precedence list determination" of "ISO/IEC 9075-2:2011
Information technology — Database languages - SQL — Part 2: Foundation (SQL/Foundation)", the type precedence lists of primitive data types are as following:

- Byte: Byte, Short, Int, Long, Decimal, Float, Double
- Short: Short, Int, Long, Decimal, Float, Double
- Int: Int, Long, Decimal, Float, Double
- Long: Long, Decimal, Float, Double
- Decimal: Any wider Numeric type
- Float: Float, Double
- Double: Double
- String: String
- Date: Date, Timestamp
- Timestamp: Timestamp
- Binary: Binary
- Boolean: Boolean
- Interval: Interval

As for complex data types, Spark will determine the precedent list recursively based on their sub-types.

With the definition of type precedent list, the general type coercion rules are as following:
- Data type S is allowed to be implicitly cast as type T iff T is in the precedence list of S
- Comparison is allowed iff the data type precedence list of both sides has at least one common element. When evaluating the comparison, Spark casts both sides as the tightest common data type of their precedent lists.
- There should be at least one common data type among all the children's precedence lists for the following operators. The data type of the operator is the tightest common precedent data type.
```
 In, Except(odd), Intersect, Greatest, Least, Union, If, CaseWhen, CreateArray, Array Concat,Sequence, MapConcat, CreateMap
```

- For complex types (struct, array, map), Spark recursively looks into the element type and applies the rules above. If the element nullability is converted from true to false, add runtime null check to the elements.

Note: this new type coercion system will allow implicit converting String type literals as other primitive types, in case of breaking too many existing Spark SQL queries. This is a special rule and it is not from the ANSI SQL standard.
### Why are the changes needed?

The current type coercion rules are complex. Also, they are very hard to describe and understand. For details please refer the attached documentation "Default Type coercion rules of Spark"
[Default Type coercion rules of Spark.pdf](https://github.com/apache/spark/files/5874362/Default.Type.coercion.rules.of.Spark.pdf)

This PR is to create a new and strict type coercion system under ANSI mode. The rules are simple and clean, so that users can follow them easily

### Does this PR introduce _any_ user-facing change?

Yes,  new implicit cast syntax rules in ANSI mode. All the details are in the first section of this description.

### How was this patch tested?

### What changes were proposed in this pull request?

In the PR, I propose to extend the `MSCK REPAIR TABLE` command, and support new options `{ADD|DROP|SYNC} PARTITIONS`. In particular:

1. Extend the logical node `RepairTable`, and add two new flags `enableAddPartitions` and `enableDropPartitions`.
2. Add similar flags to the v1 execution node `AlterTableRecoverPartitionsCommand`
3. Add new method `dropPartitions()` to `AlterTableRecoverPartitionsCommand` which drops partitions from the catalog if their locations in the file system don't exist.
4. Updated public docs about the `MSCK REPAIR TABLE` command:
<img width="1037" alt="Screenshot 2021-02-16 at 13 46 39" src="https://user-images.githubusercontent.com/1580697/108052607-7446d280-705d-11eb-8e25-7398254787a4.png">

Closes #31097

### Why are the changes needed?
- The changes allow to recover tables with removed partitions. The example below portraits the problem:
```sql
spark-sql> create table tbl2 (col int, part int) partitioned by (part);
spark-sql> insert into tbl2 partition (part=1) select 1;
spark-sql> insert into tbl2 partition (part=0) select 0;
spark-sql> show table extended like 'tbl2' partition (part = 0);
default	tbl2	false	Partition Values: [part=0]
Location: file:/Users/maximgekk/proj/apache-spark/spark-warehouse/tbl2/part=0
...
```
Remove the partition (part = 0) from the filesystem:
```
$ rm -rf /Users/maximgekk/proj/apache-spark/spark-warehouse/tbl2/part=0
```
Even after recovering, we cannot query the table:
```sql
spark-sql> msck repair table tbl2;
spark-sql> select * from tbl2;
21/01/08 22:49:13 ERROR SparkSQLDriver: Failed in [select * from tbl2]
org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: file:/Users/maximgekk/proj/apache-spark/spark-warehouse/tbl2/part=0
```

- To have feature parity with Hive: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-RecoverPartitions(MSCKREPAIRTABLE)

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, we can query recovered table:
```sql
spark-sql> msck repair table tbl2 sync partitions;
spark-sql> select * from tbl2;
1	1
spark-sql> show partitions tbl2;
part=1
```

### How was this patch tested?
- By running the modified test suite:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *MsckRepairTableParserSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *PlanResolutionSuite"

Linhong Liu be675a052c [SPARK-34490][SQL] Analysis should fail if the view refers a dropped table
### What changes were proposed in this pull request?
When resolving a view, we use the captured view name in `AnalysisContext` to
distinguish whether a relation name is a view or a table. But if the resolution failed,
other rules (e.g. `ResolveTables`) will try to resolve the relation again but without
`AnalysisContext`. So, in this case, the resolution may be incorrect. For example,
if the view refers to a dropped table while a view with the same name exists, the
dropped table will be resolved as a view rather than an unresolved exception.

Sean Owen f78466dca6 [SPARK-7768][CORE][SQL] Open UserDefinedType as a Developer API
### What changes were proposed in this pull request?

UserDefinedType and UDTRegistration become public Developer APIs, not package-private to Spark.

### Why are the changes needed?

This proposes to simply open up the UserDefinedType class as a developer API. It was public in 1.x, but closed in 2.x for some possible redesign that does not seem to have happened.

Other libraries have managed to define UDTs anyway by inserting shims into the Spark namespace, and this evidently has worked OK. But package isolation in Java 9+ breaks this.

The logic here is mostly: this is de facto a stable API, so can at least be open to developers with the usual caveats about developer APIs.

Open questions:

- Is there in fact some important redesign that's needed before opening it? The comment to this effect is from 2016
- Is this all that needs to be opened up? Like PythonUserDefinedType?
- Should any of this be kept package-private?

This was first proposed in https://github.com/apache/spark/pull/16478 though it was a larger change, but, the other API issues it was fixing seem to have been addressed already (e.g. no need to return internal Spark types). It was never really reviewed.

My hunch is that there isn't much downside, and some upside, to just opening this as-is now.

### Does this PR introduce _any_ user-facing change?

UserDefinedType becomes visible to developers to subclass.

### How was this patch tested?

Existing tests; there is no change to the existing logic.

Zhichao Zhang 96bcb4bbe4 [SPARK-34283][SQL] Combines all adjacent 'Union' operators into a single 'Union' when using 'Dataset.union.distinct.union.distinct'
### What changes were proposed in this pull request?

Handled 'Deduplicate(Keys, Union)' operation in rule 'CombineUnions' to combine adjacent 'Union' operators  into a single 'Union' if necessary when using 'Dataset.union.distinct.union.distinct'.
Currently only handle distinct-like 'Deduplicate', where the keys == output, for example:
```
val df1 = Seq((1, 2, 3)).toDF("a", "b", "c")
val df2 = Seq((6, 2, 5)).toDF("a", "b", "c")
val df3 = Seq((2, 4, 3)).toDF("c", "a", "b")
val df4 = Seq((1, 4, 5)).toDF("b", "a", "c")
val unionDF1 = df1.unionByName(df2).dropDuplicates(Seq("b", "a", "c"))
      .unionByName(df3).dropDuplicates().unionByName(df4)
      .dropDuplicates("a")
```
In this case, **all Union operators will be combined**.
but,
```
val df1 = Seq((1, 2, 3)).toDF("a", "b", "c")
val df2 = Seq((6, 2, 5)).toDF("a", "b", "c")
val df3 = Seq((2, 4, 3)).toDF("c", "a", "b")
val df4 = Seq((1, 4, 5)).toDF("b", "a", "c")
val unionDF = df1.unionByName(df2).dropDuplicates(Seq("a"))
      .unionByName(df3).dropDuplicates("c").unionByName(df4)
      .dropDuplicates("b")
```
In this case, **all unions will not be combined, because the Deduplicate.keys doesn't equal to Union.output**.

### Why are the changes needed?

When using 'Dataset.union.distinct.union.distinct', the operator is  'Deduplicate(Keys, Union)', but AstBuilder transform sql-style 'Union' to operator 'Distinct(Union)', the rule 'CombineUnions' in Optimizer only handle 'Distinct(Union)' operator but not Deduplicate(Keys, Union).

Max Gekk 8f7ec4b28e [SPARK-34454][SQL] Mark legacy SQL configs as internal
### What changes were proposed in this pull request?
1. Make the following SQL configs as internal:
    - spark.sql.legacy.allowHashOnMapType
    - spark.sql.legacy.sessionInitWithConfigDefaults
2. Add a test to check that all SQL configs from the `legacy` namespace are marked as internal configs.

### Why are the changes needed?
Assuming that legacy SQL configs shouldn't be set by users in common cases. The purpose of such configs is to allow switching to old behavior in corner cases. So, the configs should be marked as internals.

### Does this PR introduce _any_ user-facing change?
Should not.

### How was this patch tested?

Max Gekk 5957bc18a1 [SPARK-34451][SQL] Add alternatives for datetime rebasing SQL configs and deprecate legacy configs
### What changes were proposed in this pull request?
Move the datetime rebase SQL configs from the `legacy` namespace by:
1. Renaming of the existing rebase configs like `spark.sql.legacy.parquet.datetimeRebaseModeInRead` -> `spark.sql.parquet.datetimeRebaseModeInRead`.
2. Add the legacy configs as alternatives
3. Deprecate the legacy rebase configs.

### Why are the changes needed?
The rebasing SQL configs like `spark.sql.legacy.parquet.datetimeRebaseModeInRead` can be used not only for migration from previous Spark versions but also to read/write datatime columns saved by other systems/frameworks/libs. So, the configs shouldn't be considered as legacy configs.

### Does this PR introduce _any_ user-facing change?
Should not. Users will see a warning if they still use one of the legacy configs.

### How was this patch tested?
1. Manually checking new configs:
```scala
scala> spark.conf.get("spark.sql.parquet.datetimeRebaseModeInRead")
res0: String = EXCEPTION

scala> spark.conf.set("spark.sql.legacy.parquet.datetimeRebaseModeInRead", "LEGACY")

Max Gekk 03161055de [SPARK-34424][SQL][TESTS] Fix failures of HiveOrcHadoopFsRelationSuite
### What changes were proposed in this pull request?
Modify `RandomDataGenerator.forType()` to allow generation of dates/timestamps that are valid in both Julian and Proleptic Gregorian calendars. Currently, the function can produce a date (for example `1582-10-06`) which is valid in the Proleptic Gregorian calendar. Though it cannot be saved to ORC files AS IS since ORC format (ORC libs in fact) assumes Julian calendar. So, Spark shifts `1582-10-06` to the next valid date `1582-10-15` while saving it to ORC files. And as a consequence of that, the test fails because it compares original date `1582-10-06` and the date `1582-10-15` loaded back from the ORC files.

In this PR, I propose to generate valid dates/timestamps in both calendars for ORC datasource till SPARK-34440 is resolved.

### Why are the changes needed?
The changes fix failures of `HiveOrcHadoopFsRelationSuite`. For instance, the test "test all data types" fails with the seed **610710213676**:
```

David Li 9b875ceada [SPARK-32953][PYTHON][SQL] Add Arrow self_destruct support to toPandas
### What changes were proposed in this pull request?

Creating a Pandas dataframe via Apache Arrow currently can use twice as much memory as the final result, because during the conversion, both Pandas and Arrow retain a copy of the data. Arrow has a "self-destruct" mode now (Arrow >= 0.16) to avoid this, by freeing each column after conversion. This PR integrates support for this in toPandas, handling a couple of edge cases:

self_destruct has no effect unless the memory is allocated appropriately, which is handled in the Arrow serializer here. Essentially, the issue is that self_destruct frees memory column-wise, but Arrow record batches are oriented row-wise:

```
Record batch 0: allocation 0: column 0 chunk 0, column 1 chunk 0, ...
Record batch 1: allocation 1: column 0 chunk 1, column 1 chunk 1, ...
```

In this scenario, Arrow will drop references to all of column 0's chunks, but no memory will actually be freed, as the chunks were just slices of an underlying allocation. The PR copies each column into its own allocation so that memory is instead arranged as so:

```
Record batch 0: allocation 0 column 0 chunk 0, allocation 1 column 1 chunk 0, ...
Record batch 1: allocation 2 column 0 chunk 1, allocation 3 column 1 chunk 1, ...
```

The optimization is disabled by default, and can be enabled with the Spark SQL conf "spark.sql.execution.arrow.pyspark.selfDestruct.enabled" set to "true". We can't always apply this optimization because it's more likely to generate a dataframe with immutable buffers, which Pandas doesn't always handle well, and because it is slower overall (since it only converts one column at a time instead of in parallel).

### Why are the changes needed?

This lets us load larger datasets - in particular, with N bytes of memory, before we could never load a dataset bigger than N/2 bytes; now the overhead is more like N/1.25 or so.

### Does this PR introduce _any_ user-facing change?

Yes - it adds a new SQL conf "spark.sql.execution.arrow.pyspark.selfDestruct.enabled"

### How was this patch tested?

See the [mailing list](http://apache-spark-developers-list.1001551.n3.nabble.com/DISCUSS-Reducing-memory-usage-of-toPandas-with-Arrow-quot-self-destruct-quot-option-td30149.html) - it was tested with Python memory_profiler. Unit tests added to check memory within certain bounds and correctness with the option enabled.

gengjiaan 32a523b56f [SPARK-34234][SQL] Remove TreeNodeException that didn't work
### What changes were proposed in this pull request?
`TreeNodeException` causes the error msg not clear and it didn't work well.
Because the `TreeNodeException` looks redundancy, we could remove it.

There are show a case:
```
val df = Seq(("1", 1), ("1", 2), ("2", 3), ("2", 4)).toDF("x", "y")
val hashAggDF = df.groupBy("x").agg(c, sum("y"))
```
The above code will use `HashAggregateExec`. In order to ensure that an exception will be thrown when executing `HashAggregateExec`, I added `throw new RuntimeException("calculate error")` into 72b7f8abfb/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/HashAggregateExec.scala (L85)

So, if the above code is executed, `RuntimeException("calculate error")` will be thrown.
Before this PR, the error is:

Chao Sun 0986f16c8d [SPARK-34347][SQL] CatalogImpl.uncacheTable should invalidate in cascade for temp views
### What changes were proposed in this pull request?

This PR includes the following changes:
1. in `CatalogImpl.uncacheTable`, invalidate caches in cascade when the target table is
 a temp view, and `spark.sql.legacy.storeAnalyzedPlanForView` is false (default value).
2. make `SessionCatalog.lookupTempView` public and return processed temp view plan (i.e., with `View` op).

### Why are the changes needed?

Following [SPARK-34052](https://issues.apache.org/jira/browse/SPARK-34052) (#31107), we should invalidate in cascade for `CatalogImpl.uncacheTable` when the table is a temp view, so that the behavior is consistent.

### Does this PR introduce _any_ user-facing change?

Yes, now `SQLContext.uncacheTable` will drop temp view in cascade by default.

### How was this patch tested?

Added a UT

Angerszhuuuu 123365e05c [SPARK-34240][SQL] Unify output of SHOW TBLPROPERTIES clause's output attribute's schema and ExprID
### What changes were proposed in this pull request?
Passing around the output attributes should have more benefits like keeping the exprID unchanged to avoid bugs when we apply more operators above the command output DataFrame.

This PR did 2 things :

1. After this pr, a `SHOW TBLPROPERTIES` clause's output shows `key` and `value` columns whether you specify the table property `key`. Before this pr, a `SHOW TBLPROPERTIES` clause's output only show a `value` column when you specify the table property `key`..
2. Keep `SHOW TBLPROPERTIES` command's output attribute exprId unchanged.

### Why are the changes needed?
 1. Keep `SHOW TBLPROPERTIES`'s output schema consistence
 2. Keep `SHOW TBLPROPERTIES` command's output attribute exprId unchanged.

### Does this PR introduce _any_ user-facing change?
After this pr, a `SHOW TBLPROPERTIES` clause's output shows `key` and `value` columns whether you specify the table property `key`. Before this pr, a `SHOW TBLPROPERTIES` clause's output only show a `value` column when you specify the table property `key`.

Before this PR:
```
sql > SHOW TBLPROPERTIES tabe_name('key')
value
value_of_key
```

After this PR
```
sql > SHOW TBLPROPERTIES tabe_name('key')
key value
key value_of_key
```

yikf 37fe8c6d3c [SPARK-34395][SQL] Clean up unused code for code simplifications
### What changes were proposed in this pull request?
Currently, we pass the default value `EmptyRow` to method `checkEvaluation` in the `StringExpressionsSuite`, but the default value of the 'checkEvaluation' method parameter is the `emptyRow`.

We can clean the parameter for Code Simplifications.

### Why are the changes needed?
for Code Simplifications

**before**:
```
def testConcat(inputs: String*): Unit = {
  val expected = if (inputs.contains(null)) null else inputs.mkString
  checkEvaluation(Concat(inputs.map(Literal.create(_, StringType))), expected, EmptyRow)
}
```
**after**:
```
def testConcat(inputs: String*): Unit = {
  val expected = if (inputs.contains(null)) null else inputs.mkString
  checkEvaluation(Concat(inputs.map(Literal.create(_, StringType))), expected)
}
```

Terry Kim c92e408aa1 [SPARK-34388][SQL] Propagate the registered UDF name to ScalaUDF, ScalaUDAF and ScalaAggregator
### What changes were proposed in this pull request?

This PR proposes to propagate the name used for registering UDFs to `ScalaUDF`, `ScalaUDAF` and `ScaalAggregator`.

Note that `PythonUDF` gets the name correctly: 466c045bfa/python/pyspark/sql/udf.py (L358-L359)
, and same for Hive UDFs:
466c045bfa/sql/hive/src/main/scala/org/apache/spark/sql/hive/HiveSessionCatalog.scala (L67)
### Why are the changes needed?

This PR can help in the following scenarios:
1) Better EXPLAIN output
2) By adding  `def name: String` to `UserDefinedExpression`, we can match an expression by `UserDefinedExpression` and look up the catalog, an use case needed for #31273.

### Does this PR introduce _any_ user-facing change?

The EXPLAIN output involving udfs will be changed to use the name used for UDF registration.

For example, for the following:
```
sql("CREATE TEMPORARY FUNCTION test_udf AS 'org.apache.spark.examples.sql.Spark33084'")
sql("SELECT test_udf(col1) FROM VALUES (1), (2), (3)").explain(true)
```
The output of the optimized plan will change from:
```
Aggregate [spark33084(cast(col1#223 as bigint), org.apache.spark.examples.sql.Spark330846906be0f, 1, 1) AS spark33084(col1)#237]
+- LocalRelation [col1#223]
```
to
```
Aggregate [test_udf(cast(col1#223 as bigint), org.apache.spark.examples.sql.Spark330847a62d697, 1, 1, Some(test_udf)) AS test_udf(col1)#237]
+- LocalRelation [col1#223]
```

### How was this patch tested?

Added new tests.

Linhong Liu 037bfb2dbc [SPARK-33438][SQL] Eagerly init objects with defined SQL Confs for command set -v
### What changes were proposed in this pull request?
In Spark, `set -v` is defined as "Queries all properties that are defined in the SQLConf of the sparkSession".
But there are other external modules that also define properties and register them to SQLConf. In this case,
it can't be displayed by `set -v` until the conf object is initiated (i.e. calling the object at least once).

In this PR, I propose to eagerly initiate all the objects registered to SQLConf, so that `set -v` will always output
the completed properties.

### Why are the changes needed?
Improve the `set -v` command to produces completed and  deterministic results

### Does this PR introduce _any_ user-facing change?
`set -v` command will dump more configs

### How was this patch tested?
existing tests

gengjiaan 2c243c93d9 [SPARK-34157][SQL] Unify output of SHOW TABLES and pass output attributes properly
### What changes were proposed in this pull request?
The current implement of some DDL not unify the output and not pass the output properly to physical command.
Such as: The `ShowTables` output attributes `namespace`, but `ShowTablesCommand` output attributes `database`.

As the query plan, this PR pass the output attributes from `ShowTables` to `ShowTablesCommand`, `ShowTableExtended ` to `ShowTablesCommand`.

Take `show tables` and `show table extended like 'tbl'` as example.
The output before this PR:
`show tables`
|database|tableName|isTemporary|
-- | -- | --
| default|      tbl|      false|

If catalog is v2 session catalog, the output before this PR:
|namespace|tableName|
-- | --
| default|      tbl

`show table extended like 'tbl'`
|database|tableName|isTemporary|         information|
-- | -- | -- | --
| default|      tbl|      false|Database: default...|

The output after this PR:
`show tables`
|namespace|tableName|isTemporary|
-- | -- | --
|  default|      tbl|      false|

`show table extended like 'tbl'`
|namespace|tableName|isTemporary|         information|
-- | -- | -- | --
|  default|      tbl|      false|Database: default...|

### Why are the changes needed?
This PR have benefits as follows:
First, Unify schema for the output of SHOW TABLES.
Second, pass the output attributes could keep the expr ID unchanged, so that avoid bugs when we apply more operators above the command output dataframe.

### Does this PR introduce _any_ user-facing change?
Yes.
The output schema of `SHOW TABLES` replace `database` by `namespace`.

### How was this patch tested?
Jenkins test.

Closes #31245 from beliefer/SPARK-34157.

tanel.kiis@gmail.com c73f70bb0d [SPARK-34141][SQL] Remove side effect from ExtractGenerator
### What changes were proposed in this pull request?

Rewrote one `ExtractGenerator` case such that it would not rely on a side effect of the flatmap function.

### Why are the changes needed?

With the dataframe api it is possible to have a lazy sequence as the `output` of a `LogicalPlan`. When exploding a column on this dataframe using the `withColumn("newName", explode(col("name")))` method, the `ExtractGenerator` does not extract the generator and `CheckAnalysis` would throw an exception.

Wenchen Fan 989eb6884d [SPARK-34331][SQL] Speed up DS v2 metadata col resolution
### What changes were proposed in this pull request?

This is a follow-up of https://github.com/apache/spark/pull/28027

https://github.com/apache/spark/pull/28027 added a DS v2 API that allows data sources to produce metadata/hidden columns that can only be seen when it's explicitly selected. The way we integrate this API into Spark is:
1. The v2 relation gets normal output and metadata output from the data source, and the metadata output is excluded from the plan output by default.
2. column resolution can resolve `UnresolvedAttribute` with metadata columns, even if the child plan doesn't output metadata columns.
3. An analyzer rule searches the query plan, trying to find a node that has missing inputs. If such node is found, transform the sub-plan of this node, and update the v2 relation to include the metadata output.

The analyzer rule in step 3 brings a perf regression, for queries that do not read v2 tables at all. This rule will calculate `QueryPlan.inputSet` (which builds an `AttributeSet` from outputs of all children) and `QueryPlan.missingInput` (which does a set exclusion and creates a new `AttributeSet`) for every plan node in the query plan. In our benchmark, the TPCDS query compilation time gets increased by more than 10%

This PR proposes a simple way to improve it: we add a special metadata entry to the metadata attribute, which allows us to quickly check if a plan needs to add metadata columns: we just check all the references of this plan, and see if the attribute contains the special metadata entry, instead of calculating `QueryPlan.missingInput`.

This PR also fixes one bug: we should not change the final output schema of the plan, if we only use metadata columns in operators like filter, sort, etc.

### Why are the changes needed?

Fix perf regression in SQL query compilation, and fix a bug.

### Does this PR introduce _any_ user-facing change?

No

Terry Kim 3d7e1397d6 [SPARK-34317][SQL][FOLLOW-UP] Use relationTypeMismatchHint when UnresolvedTable is resolved to a temp view
### What changes were proposed in this pull request?

This is a follow up to #31424, and proposes to use `UnresolvedTable.relationTypeMismatchHint` when `UnresolvedTable` is resolved to a temp view.

### Why are the changes needed?

This change utilizes the type mismatch hint when a relation is resolved to a temp view when a table is expected.

For example, `ALTER TABLE tmpView SET TBLPROPERTIES ('p' = 'an')` will now include `Please use ALTER VIEW instead.` in the exception message: `tmpView is a temp view. 'ALTER TABLE ... SET TBLPROPERTIES' expects a table. Please use ALTER VIEW instead.`

### Does this PR introduce _any_ user-facing change?

Terry Kim f024d3051c [SPARK-34317][SQL] Introduce relationTypeMismatchHint to UnresolvedTable for a better error message
### What changes were proposed in this pull request?

This PR proposes to add `relationTypeMismatchHint` to `UnresolvedTable` so that if a relation is resolved to a view when a table is expected, a hint message can be included as a part of the analysis exception message. Note that the same feature is already introduced to `UnresolvedView` in #30636.

This mostly affects `ALTER TABLE` commands where the analysis exception message will now contain `Please use ALTER VIEW as instead`.

### Why are the changes needed?

To give a better error message. (The hint used to exist but got removed for commands that migrated to the new resolution framework)

### Does this PR introduce _any_ user-facing change?

Yes, now `ALTER TABLE` commands include a hint to use `ALTER VIEW` instead.
```
sql("ALTER TABLE v SET SERDE 'whatever'")
```
Before:
```
"v is a view. 'ALTER TABLE ... SET [SERDE|SERDEPROPERTIES]' expects a table.
```
After this PR:
```
"v is a view. 'ALTER TABLE ... SET [SERDE|SERDEPROPERTIES]' expects a table. Please use ALTER VIEW instead.

Linhong Liu bb9bf66bb6 [SPARK-34199][SQL] Block table.* inside function to follow ANSI standard and other SQL engines
### What changes were proposed in this pull request?
In spark, the `count(table.*)` may cause very weird result, for example:
```
select count(*) from (select 1 as a, null as b) t;
output: 1
select count(t.*) from (select 1 as a, null as b) t;
output: 0
```
 This is because spark expands `t.*` while converts `*` to count(1), this will confuse
users. After checking the ANSI standard, `count(*)` should always be `count(1)` while `count(t.*)`
is not allowed. What's more, this is also not allowed by common databases, e.g. MySQL, Oracle.

So, this PR proposes to block the ambiguous behavior and print a clear error message for users.

### Why are the changes needed?
to avoid ambiguous behavior and follow ANSI standard and other SQL engines

### Does this PR introduce _any_ user-facing change?
Yes, `count(table.*)` behavior will be blocked and output an error message.

### How was this patch tested?

HyukjinKwon 30468a9015 [SPARK-34306][SQL][PYTHON][R] Use Snake naming rule across the function APIs
### What changes were proposed in this pull request?

This PR completes snake_case rule at functions APIs across the languages, see also SPARK-10621.

In more details, this PR:
- Adds `count_distinct` in Scala Python, and R, and document that `count_distinct` is encouraged. This was not deprecated because `countDistinct` is pretty commonly used. We could deprecate in the future releases.
- (Scala-specific) adds `typedlit` but doesn't deprecate `typedLit` which is arguably commonly used. Likewise, we could deprecate in the future releases.
- Deprecates and renames:
  - `sumDistinct` -> `sum_distinct`
  - `bitwiseNOT` -> `bitwise_not`
  - `shiftLeft` -> `shiftleft` (matched with SQL name in `FunctionRegistry`)
  - `shiftRight` -> `shiftright` (matched with SQL name in `FunctionRegistry`)
  - `shiftRightUnsigned` -> `shiftrightunsigned` (matched with SQL name in `FunctionRegistry`)
  - (Scala-specific) `callUDF` -> `call_udf`

### Why are the changes needed?

To keep the consistent naming in APIs.

### Does this PR introduce _any_ user-facing change?

Yes, it deprecates some APIs and add new renamed APIs as described above.

### How was this patch tested?

Unittests were added.

Closes #31408 from HyukjinKwon/SPARK-34306.

Wenchen Fan b891862fb6 [SPARK-34269][SQL] Simplify SQL view resolution
### What changes were proposed in this pull request?

The currently SQL (temp or permanent) view resolution is done in 2 steps:
1. In `SessionCatalog`, we get the view metadata, parse the view SQL string, and wrap it with `View`.
2. At the beginning of the optimizer, we run `EliminateView`, which drops the wrapper `View`, and apply some special logic to match the view schema.

Step 2 is tricky, as we need to retain the output attr expr id, while we need to add an extra `Project` to add cast and alias. This PR simplifies the view solution by building a completed plan (with cast and alias added) in `SessionCatalog`, so that we only have 1 step.

### Why are the changes needed?

Code simplification. It also fixes issues like https://github.com/apache/spark/pull/31352

### Does this PR introduce _any_ user-facing change?

This is not right for null partition values, and cause the problem like below because `ConstantFolding` converts it to lit(null)

Kent Yao d1177b5230 [SPARK-34192][SQL] Move char padding to write side and remove length check on read side too
### What changes were proposed in this pull request?

On the read-side, the char length check and padding bring issues to CBO and predicate pushdown and other issues to the catalyst.

This PR reverts 6da5cdf1db  that added read side length check) so that we only do length check for the write side, and data sources/vendors are responsible to enforce the char/varchar constraints for data import operations like ADD PARTITION. It doesn't make sense for Spark to report errors on the read-side if the data is already dirty.

This PR also moves the char padding to the write-side, so that it 1) avoids read side issues like CBO and filter pushdown. 2) the data source can preserve char type semantic better even if it's read by systems other than Spark.

### Why are the changes needed?

closes #31278
### Does this PR introduce _any_ user-facing change?

yes, spark will not raise error for oversized char/varchar values in read side

Max Gekk bfc0235013 [SPARK-34203][SQL] Convert null partition values to __HIVE_DEFAULT_PARTITION__ in v1 In-Memory catalog
### What changes were proposed in this pull request?
In the PR, I propose to convert `null` partition values to `"__HIVE_DEFAULT_PARTITION__"` before storing in the `In-Memory` catalog internally. Currently, the `In-Memory` catalog maintains null partitions as `"__HIVE_DEFAULT_PARTITION__"` in file system but as `null` values in memory that could cause some issues like in SPARK-34203.

### Why are the changes needed?
`InMemoryCatalog` stores partitions in the file system in the Hive compatible form, for instance, it converts the `null` partition value to `"__HIVE_DEFAULT_PARTITION__"` but at the same time it keeps null as is internally. That causes an issue demonstrated by the example below:
```
$ ./bin/spark-shell -c spark.sql.catalogImplementation=in-memory
```
```scala
scala> spark.conf.get("spark.sql.catalogImplementation")
res0: String = in-memory

scala> sql("CREATE TABLE tbl (col1 INT, p1 STRING) USING parquet PARTITIONED BY (p1)")
res1: org.apache.spark.sql.DataFrame = []

scala> sql("INSERT OVERWRITE TABLE tbl VALUES (0, null)")
res2: org.apache.spark.sql.DataFrame = []

scala> sql("ALTER TABLE tbl DROP PARTITION (p1 = null)")
org.apache.spark.sql.catalyst.analysis.NoSuchPartitionsException: The following partitions not found in table 'tbl' database 'default':
Map(p1 -> null)
  at org.apache.spark.sql.catalyst.catalog.InMemoryCatalog.dropPartitions(InMemoryCatalog.scala:440)
```

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, `ALTER TABLE .. DROP PARTITION` can drop the `null` partition in `In-Memory` catalog:
```scala
scala> spark.table("tbl").show(false)
+----+----+
|col1|p1  |
+----+----+
|0   |null|
+----+----+

scala> sql("ALTER TABLE tbl DROP PARTITION (p1 = null)")
res4: org.apache.spark.sql.DataFrame = []

scala> spark.table("tbl").show(false)
+----+---+
|col1|p1 |
+----+---+
+----+---+
```

### How was this patch tested?
Added new test to `AlterTableDropPartitionSuiteBase`:
```

```

Max Gekk 6fe5a8a2ae [SPARK-34197][SQL] SessionCatalog.refreshTable() should not invalidate the relation cache for temporary views
### What changes were proposed in this pull request?
Check the name passed to `SessionCatalog.refreshTable`, and if it belongs to a temporary view, do not invalidate the relation cache.

### Why are the changes needed?
When `SessionCatalog.refreshTable` refreshes a temporary or global temporary view, it should not invalidate an entry in the relation cache associated to a table with the same name.

### Does this PR introduce _any_ user-facing change?
Should not. The change might improve performance slightly.

### How was this patch tested?
By running new UT:
```

```

yliou 512cacf7c6 [SPARK-33726][SQL] Fix for Duplicate field names during Aggregation
### What changes were proposed in this pull request?
The `RowBasedKeyValueBatch` has two different implementations depending on whether the aggregation key and value uses only fixed length data types (`FixedLengthRowBasedKeyValueBatch`) or not (`VariableLengthRowBasedKeyValueBatch`).

Before this PR the decision about the used implementation was based on by accessing the schema fields by their name.
But if two fields has the same name and one with variable length and the other with fixed length type (and all the other fields are with fixed length types) a bad decision could be made.

When `FixedLengthRowBasedKeyValueBatch` is chosen but there is a variable length field then an aggregation function could calculate with invalid values. This case is illustrated by the example used in the unit test:

`with T as (select id as a, -id as x from range(3)),
        U as (select id as b, cast(id as string) as x from range(3))
select T.x, U.x, min(a) as ma, min(b) as mb from T join U on a=b group by U.x, T.x`
where the 'x' column in the left side of the join is a Long but on the right side is a String.

### Why are the changes needed?
Fixes the issue where duplicate field name aggregation has null values in the dataframe.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Added UT, tested manually on spark shell.

Max Gekk e79c1cde1b [SPARK-34138][SQL] Keep dependants cached while refreshing v1 tables
### What changes were proposed in this pull request?
This PR changes cache refreshing of v1 tables in v1 commands. In particular, v1 table dependents are not removed from the cache after this PR. Comparing to current implementation, we just clear cached data of all dependents and keep them in the cache. So, the next actions will fill in the cached data of the original v1 table and its dependents. In more details:
1. Modified the `CatalogImpl.refreshTable()` method to use `recacheByPlan()` instead of `lookupCachedData()`, `uncacheQuery()` and `cacheQuery()`. Users can call this method via public API like `spark.catalog.refreshTable()`.
2. Rewritten the part in `CatalogImpl.refreshTable()` which was responsible for table meta-data refreshing because this code stopped to work properly after removing of the second `sparkSession.table(tableIdent)`.
3. Added new private method `invalidateCachedTable()` to `SessionCatalog`. Comparing to the existing `SessionCatalog.refreshTable`, it invalidates the relation cache only. If we called `SessionCatalog.refreshTable` from `CatalogImpl.refreshTable()`, we would refresh temporary and global temporary views twice (that could lead to refreshing file index twice).

### Why are the changes needed?
1. This should improve user experience with table/view caching. For example, let's imagine that an user has cached v1 table and cached view based on the table. And the user passed the table to external library which drops/renames/adds partitions in the v1 table. Unfortunately, the user gets the view uncached after that even he/she hasn't uncached the view explicitly.
2. To improve code maintenance.
3. To reduce the amount of calls to Hive external catalog.
4. Also this should speed up table recaching.
5. To have the same behavior as for v2 tables supported by https://github.com/apache/spark/pull/31172

### Does this PR introduce _any_ user-facing change?
From the view of the correctness of query results, there are no behavior changes but the changes might influence on consuming memory and query execution time. For example:

Before:
```scala
scala> sql("CREATE TABLE tbl (c int)")
scala> sql("CACHE TABLE tbl")
scala> sql("CREATE VIEW v AS SELECT * FROM tbl")
scala> sql("CACHE TABLE v")

scala> spark.catalog.isCached("v")
res6: Boolean = true
scala> spark.catalog.refreshTable("tbl")

scala> spark.catalog.isCached("v")
res8: Boolean = false
```

After:
```scala
scala> spark.catalog.refreshTable("tbl")

scala> spark.catalog.isCached("v")
res8: Boolean = true
```

### How was this patch tested?
1. Added new unit tests that create a view, a temporary view and a global temporary view on top of v1/v2 tables, and refresh the base table via `ALTER TABLE .. ADD/DROP/RENAME PARTITION`.
2. By running the unified test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableAddPartitionSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableDropPartitionSuite"

yi.wu f498977222 [SPARK-34178][SQL] Copy tags for the new node created by MultiInstanceRelation.newInstance
### What changes were proposed in this pull request?

Call `copyTagsFrom` for the new node created by `MultiInstanceRelation.newInstance()`.

### Why are the changes needed?

```scala
val df = spark.range(2)
df.join(df, df("id") <=> df("id")).show()
```

For this query, it's supposed to be non-ambiguous join by the rule `DetectAmbiguousSelfJoin` because of the same attribute reference in the condition:

537a49fc09/sql/core/src/main/scala/org/apache/spark/sql/execution/analysis/DetectAmbiguousSelfJoin.scala (L125)

However, `DetectAmbiguousSelfJoin` can not apply this prediction due to the right side plan doesn't contain the dataset_id TreeNodeTag, which is missing after `MultiInstanceRelation.newInstance`. That's why we should preserve the tags info for the copied node.

Fortunately, the query is still considered as non-ambiguous join because `DetectAmbiguousSelfJoin` only checks the left side plan and the reference is the same as the left side plan. However, this's not the expected behavior but only a coincidence.

### Does this PR introduce _any_ user-facing change?

No.

Chao Sun 902a08b9e6 [SPARK-34052][SQL] store SQL text for a temp view created using "CACHE TABLE .. AS SELECT"
### What changes were proposed in this pull request?

This passes original SQL text to `CacheTableAsSelect` command in DSv1 and v2 so that it will be stored instead of the analyzed logical plan, similar to `CREATE VIEW` command.

In addition, this changes the behavior of dropping temporary view to also invalidate dependent caches in a cascade, when the config `SQLConf.STORE_ANALYZED_PLAN_FOR_VIEW` is false (which is the default value).

### Why are the changes needed?

Currently, after creating a temporary view with `CACHE TABLE ... AS SELECT` command, the view can still be queried even after the source table is dropped or replaced (in v2). This can cause correctness issue.

For instance, in the following:
```sql
> CREATE TABLE t ...;
> CACHE TABLE v AS SELECT * FROM t;
> DROP TABLE t;
> SELECT * FROM v;
```
The last select query still returns the old (and stale) result instead of fail. Note that the cache is already invalidated as part of dropping table `t`, but the temporary view `v` still exist.

On the other hand, the following:
```sql
> CREATE TABLE t ...;
> CREATE TEMPORARY VIEW v AS SELECT * FROM t;
> CACHE TABLE v;
> DROP TABLE t;
> SELECT * FROM v;
```
will throw "Table or view not found" error in the last select query.

This is related to #30567 which aligns the behavior of temporary view and global view by storing the original SQL text for temporary view, as opposed to the analyzed logical plan. However, the PR only handles `CreateView` case but not the `CacheTableAsSelect` case.

This also changes uncache logic and use cascade invalidation for temporary views created above. This is to align its behavior to how a permanent view is handled as of today, and also to avoid potential issues where a dependent view becomes invalid while its data is still kept in cache.

### Does this PR introduce _any_ user-facing change?

Yes, now when `SQLConf.STORE_ANALYZED_PLAN_FOR_VIEW` is set to false (the default value), whenever a table/permanent view/temp view that a cached view depends on is dropped, the cached view itself will become invalid during analysis, i.e., user will get "Table or view not found" error. In addition, when the dependent is a temp view in the previous case, the cache itself will also be invalidated.

### How was this patch tested?

Modified/Enhanced some existing tests.

Kent Yao 6fa2fb9eb5 [SPARK-34130][SQL] Impove preformace for char varchar padding and length check with StaticInvoke
### What changes were proposed in this pull request?

This could reduce the `generate.java` size to prevent codegen fallback which causes performance regression.

here is a case from tpcds that could be fixed by this improvement
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/133964/testReport/org.apache.spark.sql.execution/LogicalPlanTagInSparkPlanSuite/q41/

The original case generate 20K bytes, we are trying to reduce it to less than 8k
### Why are the changes needed?

performance improvement as in the PR benchmark test, the performance  w/ codegen is 2~3x better than w/o codegen.

### Does this PR introduce _any_ user-facing change?

no

### How was this patch tested?

yes, it's a code reflect so the existing ut should be enough

cross-check with https://github.com/apache/spark/pull/31012 where the tpcds shall all pass

benchmark compared with master

Max Gekk a98e77c113 [SPARK-34143][SQL][TESTS] Fix adding partitions to fully partitioned v2 tables
### What changes were proposed in this pull request?
While adding new partition to v2 `InMemoryAtomicPartitionTable`/`InMemoryPartitionTable`, add single row to the table content when the table is fully partitioned.

### Why are the changes needed?
The `ALTER TABLE .. ADD PARTITION` command does not change content of fully partitioned v2 table. For instance, `INSERT INTO` changes table content:
```scala
      sql(s"CREATE TABLE t (p0 INT, p1 STRING) USING _ PARTITIONED BY (p0, p1)")
      sql(s"INSERT INTO t SELECT 1, 'def'")
      sql(s"SELECT * FROM t").show(false)

+---+---+
|p0 |p1 |
+---+---+
|1  |def|
+---+---+
```
but `ALTER TABLE .. ADD PARTITION` doesn't change v2 table content:
```scala
      sql(s"ALTER TABLE t ADD PARTITION (p0 = 0, p1 = 'abc')")
      sql(s"SELECT * FROM t").show(false)

+---+---+
|p0 |p1 |
+---+---+
+---+---+
```

### Does this PR introduce _any_ user-facing change?
No, the changes impact only on tests but for the example above in tests:
```scala
      sql(s"ALTER TABLE t ADD PARTITION (p0 = 0, p1 = 'abc')")
      sql(s"SELECT * FROM t").show(false)

+---+---+
|p0 |p1 |
+---+---+
|0  |abc|
+---+---+
```

### How was this patch tested?
By running the unified tests for `ALTER TABLE .. ADD PARTITION`.

ulysses-you 055124a048 [SPARK-34150][SQL] Strip Null literal.sql in resolve alias
### What changes were proposed in this pull request?

Change null Literal to PrettyAttribute during ResolveAlias.

### Why are the changes needed?

We will convert `Literal(null)` to target data type during analysis. Then the generated alias name will include something like `CAST(NULL AS String)` instead of `NULL`.
```
spark.sql("SELECT RAND(null)").columns

-- before
rand(CAST(NULL AS INT))

-- after
rand(NULL)
```

### Does this PR introduce _any_ user-facing change?

Yes, the default column name maybe changed.

### How was this patch tested?

Add test and pass exists test.

Terry Kim 78893b8dc9 [SPARK-34139][SQL] UnresolvedRelation should retain SQL text position for DDL commands
### What changes were proposed in this pull request?

Currently, there are many DDL commands where the position of the unresolved identifiers are incorrect:
```
scala> sql("CACHE TABLE unknown")
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 0;
```
, whereas the `pos` should be `12`.

This PR proposes to fix this issue for commands using `UnresolvedRelation`:
```
CACHE TABLE unknown
UNCACHE TABLE unknown
DELETE FROM unknown
UPDATE unknown SET name='abc'
MERGE INTO unknown1 AS target USING unknown2 AS source ON target.col = source.col WHEN MATCHED THEN DELETE
INSERT INTO TABLE unknown SELECT 1
INSERT OVERWRITE TABLE unknown VALUES (1, 'a')
```

### Why are the changes needed?

To fix a bug.

### Does this PR introduce _any_ user-facing change?

Yes, now the above example will print the following:
```
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 12;
```

### How was this patch tested?

Add a new test.

Max Gekk c3d81fbe79 [SPARK-34060][SQL][FOLLOWUP] Preserve serializability of canonicalized CatalogTable
### What changes were proposed in this pull request?
Replace `toMap` by `map(identity).toMap` while getting canonicalized representation of `CatalogTable`. `CatalogTable` became not serializable after https://github.com/apache/spark/pull/31112 due to usage of `filterKeys`. The workaround was taken from https://github.com/scala/bug/issues/7005.

### Why are the changes needed?
This prevents the errors like:
```
[info]   org.apache.spark.SparkException: Job aborted due to stage failure: Task not serializable: java.io.NotSerializableException: scala.collection.immutable.MapLike$$anon$1

```

### Does this PR introduce _any_ user-facing change?
Should not.

Chao Sun b6f46ca297 [SPARK-33212][BUILD] Upgrade to Hadoop 3.2.2 and move to shaded clients for Hadoop 3.x profile
### What changes were proposed in this pull request?

This:
1. switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x.
2. upgrade built-in version for Hadoop 3.x to Hadoop 3.2.2

Note that for Hadoop 2.7, we'll still use the same modules such as hadoop-client.

In order to still keep default Hadoop profile to be hadoop-3.2, this defines the following Maven properties:

```
hadoop-client-api.artifact
hadoop-client-runtime.artifact
hadoop-client-minicluster.artifact
```

which default to:
```
hadoop-client-api
hadoop-client-runtime
hadoop-client-minicluster
```
but all switch to `hadoop-client` when the Hadoop profile is hadoop-2.7. A side affect from this is we'll import the same dependency multiple times. For this I have to disable Maven enforcer `banDuplicatePomDependencyVersions`.

Besides above, there are the following changes:
- explicitly add a few dependencies which are imported via transitive dependencies from Hadoop jars, but are removed from the shaded client jars.
- removed the use of `ProxyUriUtils.getPath` from `ApplicationMaster` which is a server-side/private API.
- modified `IsolatedClientLoader` to exclude `hadoop-auth` jars when Hadoop version is 3.x. This change should only matter when we're not sharing Hadoop classes with Spark (which is _mostly_ used in tests).

### Why are the changes needed?

Hadoop 3.2.2 is released with new features and bug fixes, so it's good for the Spark community to adopt it. However, latest Hadoop versions starting from Hadoop 3.2.1 have upgraded to use Guava 27+. In order to resolve Guava conflicts, this takes the approach by switching to shaded client jars provided by Hadoop. This also has the benefits of avoid pulling other 3rd party dependencies from Hadoop side so as to avoid more potential future conflicts.

### Does this PR introduce _any_ user-facing change?

When people use Spark with `hadoop-provided` option, they should make sure class path contains `hadoop-client-api` and `hadoop-client-runtime` jars. In addition, they may need to make sure these jars appear before other Hadoop jars in the order. Otherwise, classes may be loaded from the other non-shaded Hadoop jars and cause potential conflicts.

### How was this patch tested?

Relying on existing tests.

The type-coercion for numeric types of average and sum is not necessary at all, as the resultType and sumType can prevent the overflow.

### Why are the changes needed?

rm unnecessary logic which may cause potential performance regressions

### Does this PR introduce _any_ user-facing change?

no
### How was this patch tested?

tpcds tests for plan

Kent Yao acd6c1271b [SPARK-34114][SQL] should not trim right for read-side char length check and padding
### What changes were proposed in this pull request?

On the read-side, we should respect the original data instead of trimming it first.

It brings extra overhead on the code-gen code side, trimming and padding for the same field, and it's also unnecessary and a bug

### Why are the changes needed?

bugfix and perf regression

Kousuke Saruta bec80d7eec [SPARK-34101][SQL] Make spark-sql CLI configurable for the behavior of printing header by SET command
### What changes were proposed in this pull request?

This PR introduces a new property `spark.sql.cli.print.header` to let users change the behavior of printing header for spark-sql CLI by SET command.

### Why are the changes needed?

Like Hive CLI, spark-sql CLI accepts `hive.cli.print.header` property and we can change the behavior of printing header.
But spark-sql CLI doesn't allow users to change Hive specific configurations dynamically by SET command.
So, it's better to support the way to change the behavior by SET command.

### Does this PR introduce _any_ user-facing change?

Yes. Users can dynamically change the behavior by SET command.

### How was this patch tested?

I confirmed with the following commands/queries.
```
spark-sql> select (1) as a, (2) as b, (3) as c, (4) as d;
1	2	3	4
Time taken: 3.218 seconds, Fetched 1 row(s)
spark-sql> set spark.sql.cli.print.header=true;
key	value
spark.sql.cli.print.header	true
Time taken: 1.506 seconds, Fetched 1 row(s)
spark-sql> select (1) as a, (2) as b, (3) as c, (4) as d;
a	b	c	d
1	2	3	4
Time taken: 0.79 seconds, Fetched 1 row(s)
```

ulysses-you 92e5cfd58d [SPARK-33989][SQL] Strip auto-generated cast when using Cast.sql
### What changes were proposed in this pull request?

This PR aims to strip auto-generated cast. The main logic is:
1. Add tag if Cast is specified by user.
2. Wrap `PrettyAttribute` in usePrettyExpression.

### Why are the changes needed?

Make sql consistent with dsl. Here is an inconsistent example before this PR:

```
-- output field name: FLOOR(1)
spark.emptyDataFrame.select(floor(lit(1)))

-- output field name: FLOOR(CAST(1 AS DOUBLE))
spark.sql("select floor(1)")
```

Note that, we don't remove the `Cast` so the auto-generated `Cast` can still work. The only changed place is `usePrettyExpression`, we use `PrettyAttribute` replace `Cast` to give a better sql string.

### Does this PR introduce _any_ user-facing change?

Yes, the default field name may change.

### How was this patch tested?

Add test and pass exists test.

We need to look recursively into children to find char/varchars.

In this PR,  we try to resolve the full attributes including the original `Aggregate` expressions and the candidates in `SortOrder` together, then use the new re-resolved `Aggregate` expressions to determine which candidate in the `SortOrder` shall be pushed. This can avoid mismatch for the same attributes w/o this change, as the expressions returned by `executeSameContext` will change when `PaddingAndLengthCheckForCharVarchar` takes effects. W/ this change, the expressions can be matched correctly.

For those unmatched, w need to look recursively into children to find char/varchars instead of the expression itself only.

Liang-Chi Hsieh 0bcbafb4b8 [SPARK-34002][SQL] Fix the usage of encoder in ScalaUDF
### What changes were proposed in this pull request?

This patch fixes few issues when using encoders to serialize input/output in `ScalaUDF`.

### Why are the changes needed?

This fixes a bug when using encoders in Scala UDF. First, the output data type should be corrected to the corresponding data type of the object serializer. Second, `catalystConverter` should not serialize `Option[_]` as the ordinary row because in `ScalaUDF` case it is serialized to a column, not the top-level row. Otherwise, there will be a redundant `value` struct wrapping the serialized `Option[_]` object.

### Does this PR introduce _any_ user-facing change?

Yes, fixing a bug of `ScalaUDF`.

### How was this patch tested?

Unit test.

Max Gekk d97e99157e [SPARK-34060][SQL] Fix Hive table caching while updating stats by ALTER TABLE .. DROP PARTITION
### What changes were proposed in this pull request?
Fix canonicalisation of `HiveTableRelation` by normalisation of `CatalogTable`, and exclude table stats and temporary fields from the canonicalized plan.

### Why are the changes needed?
This fixes the issue demonstrated by the example below:
```scala
scala> spark.conf.set("spark.sql.statistics.size.autoUpdate.enabled", true)
scala> sql(s"CREATE TABLE tbl (id int, part int) USING hive PARTITIONED BY (part)")
scala> sql("INSERT INTO tbl PARTITION (part=0) SELECT 0")
scala> sql("INSERT INTO tbl PARTITION (part=1) SELECT 1")
scala> sql("CACHE TABLE tbl")
scala> sql("SELECT * FROM tbl").show(false)
+---+----+
|id |part|
+---+----+
|0  |0   |
|1  |1   |
+---+----+

scala> spark.catalog.isCached("tbl")
scala> sql("ALTER TABLE tbl DROP PARTITION (part=0)")
scala> spark.catalog.isCached("tbl")
res19: Boolean = false
```
`ALTER TABLE .. DROP PARTITION` must keep the table in the cache.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the drop partition command keeps the table in the cache while updating table stats:
```scala
scala> sql("ALTER TABLE tbl DROP PARTITION (part=0)")
scala> spark.catalog.isCached("tbl")
res19: Boolean = true
```

### How was this patch tested?
By running new UT in `AlterTableDropPartitionSuite`.

, whereas the `pos` should be `11`.

This PR proposes to fix this issue for commands using `UnresolvedTableOrView`:
```
DROP TABLE unknown
DESCRIBE TABLE unknown
ANALYZE TABLE unknown COMPUTE STATISTICS
ANALYZE TABLE unknown COMPUTE STATISTICS FOR COLUMNS col
ANALYZE TABLE unknown COMPUTE STATISTICS FOR ALL COLUMNS
SHOW CREATE TABLE unknown
REFRESH TABLE unknown
SHOW COLUMNS FROM unknown
SHOW COLUMNS FROM unknown IN db
ALTER TABLE unknown RENAME TO t
ALTER VIEW unknown RENAME TO v
```

### Why are the changes needed?

To fix a bug.

### Does this PR introduce _any_ user-facing change?

Yes, now the above example will print the following:
```
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 11;
```

### How was this patch tested?

Add a new test.

HyukjinKwon 830249284d [SPARK-34059][SQL][CORE] Use for/foreach rather than map to make sure execute it eagerly
### What changes were proposed in this pull request?

This PR is basically a followup of https://github.com/apache/spark/pull/14332.
Calling `map` alone might leave it not executed due to lazy evaluation, e.g.)

```
scala> val foo = Seq(1,2,3)
foo: Seq[Int] = List(1, 2, 3)

scala> foo.map(println)
1
2
3
res0: Seq[Unit] = List((), (), ())

scala> foo.view.map(println)
res1: scala.collection.SeqView[Unit,Seq[_]] = SeqViewM(...)

scala> foo.view.foreach(println)
1
2
3
```

We should better use `foreach` to make sure it's executed where the output is unused or `Unit`.

### Why are the changes needed?

To prevent the potential issues by not executing `map`.

### Does this PR introduce _any_ user-facing change?

No, the current codes look not causing any problem for now.

### How was this patch tested?

I found these item by running IntelliJ inspection, double checked one by one, and fixed them. These should be all instances across the codebase ideally.

ulysses-you 48cd11c483 [SPARK-34030][SQL] Fold RepartitionByExpression num partition should at Optimizer
### What changes were proposed in this pull request?

Move `RepartitionByExpression` fold partition number code to a new rule at `Optimizer`.

### Why are the changes needed?

We meet some ploblem when backport SPARK-33806. It is because the UnresolvedFunction.foldable will throw a exception. It's ok with master branch, but it's better to do it at Optimizer. Some reason:

1. It's not always safe to call Expression.foldable before analysis.
2. fold num partition to 1 more like a optimize behavior.

### Does this PR introduce _any_ user-facing change?

No.

### What changes were proposed in this pull request?

This PR makes `StreamExecution` use the `Write` abstraction introduced in SPARK-33779.

Note: we will need separate plans for streaming writes in order to support the required distribution and ordering in SS. This change only migrates to the `Write` abstraction.

### Why are the changes needed?

These changes prevent exceptions from data sources that implement only the `build` method in `WriteBuilder`.

This PR fixes an incorrect unicode literal test in `ParserUtilsSuite`.
In that suite, string literals in queries have unicode escape characters like `\u7328` but the backslash should be escaped because
the queriy strings are given as Java strings.

Max Gekk 157b72ac9f [SPARK-33591][SQL] Recognize null in partition spec values
### What changes were proposed in this pull request?
1. Recognize `null` while parsing partition specs, and put `null` instead of `"null"` as partition values.
2. For V1 catalog: replace `null` by `__HIVE_DEFAULT_PARTITION__`.
3. For V2 catalogs: pass `null` AS IS, and let catalog implementations to decide how to handle `null`s as partition values in spec.

### Why are the changes needed?
Currently, `null` in partition specs is recognized as the `"null"` string which could lead to incorrect results, for example:
```sql
spark-sql> CREATE TABLE tbl5 (col1 INT, p1 STRING) USING PARQUET PARTITIONED BY (p1);
spark-sql> INSERT INTO TABLE tbl5 PARTITION (p1 = null) SELECT 0;
spark-sql> SELECT isnull(p1) FROM tbl5;
false
```
Even we inserted a row to the partition with the `null` value, **the resulted table doesn't contain `null`**.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above works as expected:
```sql
spark-sql> SELECT isnull(p1) FROM tbl5;
true
```

### How was this patch tested?
1. By running the affected test suites `SQLQuerySuite`, `AlterTablePartitionV2SQLSuite` and `v1/ShowPartitionsSuite`.
2. Compiling by Scala 2.13:
```
$  ./dev/change-scala-version.sh 2.13
$ ./build/sbt -Pscala-2.13 compile
```

Kent Yao 0f8e5dd445 [SPARK-34003][SQL] Fix Rule conflicts between PaddingAndLengthCheckForCharVarchar and ResolveAggregateFunctions
### What changes were proposed in this pull request?

ResolveAggregateFunctions is a hacky rule and it calls `executeSameContext` to generate a `resolved agg` to determine which unresolved sort attribute should be pushed into the agg. However, after we add the PaddingAndLengthCheckForCharVarchar rule which will rewrite the query output, thus, the `resolved agg` cannot match original attributes anymore.

It causes some dissociative sort attribute to be pushed in and fails the query

This compilation warning is due to `NoSuchPermanentFunctionException` is sub-class of `AnalysisException` and if there is `NoSuchPermanentFunctionException` be thrown out,  it will be catch by `case _: AnalysisException => failFunctionLookup(name)`,  so `case _: NoSuchPermanentFunctionException => failFunctionLookup(name)` is `unreachable code`.

yangjie01 45a4ff8e54 [SPARK-33948][SQL] Fix CodeGen error of MapObjects.doGenCode method in Scala 2.13
### What changes were proposed in this pull request?
`MapObjects.doGenCode` method will generate wrong code when `inputDataType` is `ArrayBuffer`.

For example `encode/decode for Tuple2: (ArrayBuffer[(String, String)],ArrayBuffer((a,b))) (codegen path)` in `ExpressionEncoderSuite`, the error generated code part as follow:

```
/* 126 */   private scala.collection.mutable.ArrayBuffer MapObjects_0(InternalRow i) {
/* 127 */     boolean isNull_4 = i.isNullAt(1);
/* 128 */     ArrayData value_4 = isNull_4 ?
/* 129 */     null : (i.getArray(1));
/* 130 */     scala.collection.mutable.ArrayBuffer value_3 = null;
/* 131 */
/* 132 */     if (!isNull_4) {
/* 133 */
/* 134 */       int dataLength_0 = value_4.numElements();
/* 135 */
/* 136 */       scala.Tuple2[] convertedArray_0 = null;
/* 137 */       convertedArray_0 = new scala.Tuple2[dataLength_0];
/* 138 */
/* 139 */
/* 140 */       int loopIndex_0 = 0;
/* 141 */
/* 142 */       while (loopIndex_0 < dataLength_0) {
/* 143 */         value_MapObject_lambda_variable_1 = (InternalRow) (value_4.getStruct(loopIndex_0, 2));
/* 144 */         isNull_MapObject_lambda_variable_1 = value_4.isNullAt(loopIndex_0);
/* 145 */
/* 146 */         boolean isNull_5 = false;
/* 147 */         scala.Tuple2 value_5 = null;
/* 148 */         if (!false && isNull_MapObject_lambda_variable_1) {
/* 149 */
/* 150 */           isNull_5 = true;
/* 151 */           value_5 = ((scala.Tuple2)null);
/* 152 */         } else {
/* 153 */           scala.Tuple2 value_13 = NewInstance_0(i);
/* 154 */           isNull_5 = false;
/* 155 */           value_5 = value_13;
/* 156 */         }
/* 157 */         if (isNull_5) {
/* 158 */           convertedArray_0[loopIndex_0] = null;
/* 159 */         } else {
/* 160 */           convertedArray_0[loopIndex_0] = value_5;
/* 161 */         }
/* 162 */
/* 163 */         loopIndex_0 += 1;
/* 164 */       }
/* 165 */
/* 166 */       value_3 = new org.apache.spark.sql.catalyst.util.GenericArrayData(convertedArray_0);
/* 167 */     }
/* 168 */     globalIsNull_0 = isNull_4;
/* 169 */     return value_3;
/* 170 */   }

```

Line 166 in generated code try to assign `GenericArrayData`  to `value_3(ArrayBuffer)` because `ArrayBuffer` type can't match `s.c.i.Seq` branch in Scala 2.13 in `MapObjects.doGenCode` method now.

So this pr change to use `s.c.Seq` instead of `Seq` alias to let `ArrayBuffer` type can enter  the same branch as Scala 2.12.

After this pr the generate code when `inputDataType` is `ArrayBuffer` as follow:

```
/* 126 */   private scala.collection.mutable.ArrayBuffer MapObjects_0(InternalRow i) {
/* 127 */     boolean isNull_4 = i.isNullAt(1);
/* 128 */     ArrayData value_4 = isNull_4 ?
/* 129 */     null : (i.getArray(1));
/* 130 */     scala.collection.mutable.ArrayBuffer value_3 = null;
/* 131 */
/* 132 */     if (!isNull_4) {
/* 133 */
/* 134 */       int dataLength_0 = value_4.numElements();
/* 135 */
/* 136 */       scala.collection.mutable.Builder collectionBuilder_0 = scala.collection.mutable.ArrayBuffer$.MODULE$.newBuilder();
/* 137 */       collectionBuilder_0.sizeHint(dataLength_0);
/* 138 */
/* 139 */
/* 140 */       int loopIndex_0 = 0;
/* 141 */
/* 142 */       while (loopIndex_0 < dataLength_0) {
/* 143 */         value_MapObject_lambda_variable_1 = (InternalRow) (value_4.getStruct(loopIndex_0, 2));
/* 144 */         isNull_MapObject_lambda_variable_1 = value_4.isNullAt(loopIndex_0);
/* 145 */
/* 146 */         boolean isNull_5 = false;

/* 154 */           isNull_5 = false;
/* 155 */           value_5 = value_13;
/* 156 */         }
/* 157 */         if (isNull_5) {

/* 163 */         loopIndex_0 += 1;
/* 164 */       }
/* 165 */
/* 166 */       value_3 = (scala.collection.mutable.ArrayBuffer) collectionBuilder_0.result();
/* 167 */     }
/* 168 */     globalIsNull_0 = isNull_4;

tanel.kiis@gmail.com f252a9334e [SPARK-33935][SQL] Fix CBO cost function
### What changes were proposed in this pull request?

Changed the cost function in CBO to match documentation.

### Why are the changes needed?

The parameter `spark.sql.cbo.joinReorder.card.weight` is documented as:
```
The weight of cardinality (number of rows) for plan cost comparison in join reorder: rows * weight + size * (1 - weight).
```
The implementation in `JoinReorderDP.betterThan` does not match this documentaiton:
```
def betterThan(other: JoinPlan, conf: SQLConf): Boolean = {
      if (other.planCost.card == 0 || other.planCost.size == 0) {
        false
      } else {
        val relativeRows = BigDecimal(this.planCost.card) / BigDecimal(other.planCost.card)
        val relativeSize = BigDecimal(this.planCost.size) / BigDecimal(other.planCost.size)
        relativeRows * conf.joinReorderCardWeight +
          relativeSize * (1 - conf.joinReorderCardWeight) < 1
      }
    }
```

This different implementation has an unfortunate consequence:
given two plans A and B, both A betterThan B and B betterThan A might give the same results. This happes when one has many rows with small sizes and other has few rows with large sizes.

A example values, that have this fenomen with the default weight value (0.7):
A.card = 500, B.card = 300
A.size = 30, B.size = 80
Both A betterThan B and B betterThan A would have score above 1 and would return false.

This happens with several of the TPCDS queries.

The new implementation does not have this behavior.

Chongguang LIU 976e97a80d [SPARK-33794][SQL] NextDay expression throw runtime IllegalArgumentException when receiving invalid input under ANSI mode
### What changes were proposed in this pull request?

Instead of returning NULL, the next_day function throws runtime IllegalArgumentException when ansiMode is enable and receiving invalid input of the dayOfWeek parameter.

### Why are the changes needed?

For ansiMode.

### Does this PR introduce _any_ user-facing change?

Yes.
When spark.sql.ansi.enabled = true, the next_day function will throw IllegalArgumentException when receiving invalid input of the dayOfWeek parameter.
When spark.sql.ansi.enabled = false, same behaviour as before.

### How was this patch tested?

Ansi mode is tested with existing tests.
End-to-end tests have been added.

tanel.kiis@gmail.com bb6d6b5602 [SPARK-33964][SQL] Combine distinct unions in more cases
### What changes were proposed in this pull request?

Added the `RemoveNoopOperators` rule to optimization batch `Union`.  Also made sure that the `RemoveNoopOperators` would be idempotent.

### Why are the changes needed?

In several TPCDS queries the `CombineUnions` rule does not manage to combine unions, because they have noop `Project`s between them.
The `Project`s will be removed by `RemoveNoopOperators`, but by then `ReplaceDistinctWithAggregate` has been applied and there are aggregates between the unions. Adding a copy of `RemoveNoopOperators` earlier in the optimization chain allows `CombineUnions` to work on more queries.

### Does this PR introduce _any_ user-facing change?

No

New UTs and the output of `PlanStabilitySuite`

### What changes were proposed in this pull request?
In the `saveAsTable()` and `insertInto()` methods of `DataFrameWriter`, recognize `spark_catalog` as the default session catalog in table names.

### Why are the changes needed?
1. To simplify writing of unified v1 and v2 tests
2. To improve Spark SQL user experience. `insertInto()` should have feature parity with the `INSERT INTO` sql command. Currently, `insertInto()` fails on a table from a namespace in `spark_catalog`:
```scala
scala> sql("CREATE NAMESPACE spark_catalog.ns")
scala> Seq(0).toDF().write.saveAsTable("spark_catalog.ns.tbl")
org.apache.spark.sql.AnalysisException: Couldn't find a catalog to handle the identifier spark_catalog.ns.tbl.
  at org.apache.spark.sql.DataFrameWriter.saveAsTable(DataFrameWriter.scala:629)
  ... 47 elided
scala> Seq(0).toDF().write.insertInto("spark_catalog.ns.tbl")
org.apache.spark.sql.AnalysisException: Couldn't find a catalog to handle the identifier spark_catalog.ns.tbl.
  at org.apache.spark.sql.DataFrameWriter.insertInto(DataFrameWriter.scala:498)
  ... 47 elided
```
but `INSERT INTO` succeed:
```sql
spark-sql> create table spark_catalog.ns.tbl (c int);
spark-sql> insert into spark_catalog.ns.tbl select 0;
spark-sql> select * from spark_catalog.ns.tbl;
0
```

### Does this PR introduce _any_ user-facing change?
Yes. After the changes for the example above:
```scala
scala> Seq(0).toDF().write.saveAsTable("spark_catalog.ns.tbl")
scala> Seq(1).toDF().write.insertInto("spark_catalog.ns.tbl")
scala> spark.table("spark_catalog.ns.tbl").show(false)
+-----+
|value|
+-----+
|0    |
|1    |
+-----+
```

### How was this patch tested?
By running the affected test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *.ShowPartitionsSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *.FileFormatWriterSuite"
```

Terry Kim fe33262c91 [SPARK-33918][SQL] UnresolvedView should retain SQL text position for DDL commands
### What changes were proposed in this pull request?

Currently, there are many DDL commands where the position of the unresolved identifiers are incorrect:
```
scala> sql("DROP VIEW unknown")

```
, whereas the `pos` should be `10`.

This PR proposes to fix this issue for commands using `UnresolvedTable`:
```
DROP VIEW v
ALTER VIEW v SET TBLPROPERTIES ('k'='v')
ALTER VIEW v UNSET TBLPROPERTIES ('k')
ALTER VIEW v AS SELECT 1
```

### Why are the changes needed?

To fix a bug.

### Does this PR introduce _any_ user-facing change?

kozakana 2553d53dc8 [SPARK-33897][SQL] Can't set option 'cross' in join method
### What changes were proposed in this pull request?

[The PySpark documentation](https://spark.apache.org/docs/3.0.1/api/python/pyspark.sql.html#pyspark.sql.DataFrame.join) says "Must be one of: inner, cross, outer, full, fullouter, full_outer, left, leftouter, left_outer, right, rightouter, right_outer, semi, leftsemi, left_semi, anti, leftanti and left_anti."
However, I get the following error when I set the cross option.

```
scala> val df1 = spark.createDataFrame(Seq((1,"a"),(2,"b")))
df1: org.apache.spark.sql.DataFrame = [_1: int, _2: string]

scala> val df2 = spark.createDataFrame(Seq((1,"A"),(2,"B"), (3, "C")))
df2: org.apache.spark.sql.DataFrame = [_1: int, _2: string]

scala> df1.join(right = df2, usingColumns = Seq("_1"), joinType = "cross").show()
java.lang.IllegalArgumentException: requirement failed: Unsupported using join type Cross
  at scala.Predef$.require(Predef.scala:281)
  at org.apache.spark.sql.catalyst.plans.UsingJoin.<init>(joinTypes.scala:106)
  at org.apache.spark.sql.Dataset.join(Dataset.scala:1025)
  ... 53 elided
```

### Why are the changes needed?

The documentation says cross option can be set, but when I try to set it, I get an java.lang.IllegalArgumentException.

### Does this PR introduce _any_ user-facing change?

Accepting this PR fix will behave the same as the documentation.

### How was this patch tested?

There is already a test for [JoinTypes](1b9fd67904/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/plans/JoinTypesTest.scala), but I can't find a test for the join option itself.

ulysses-you 9c30116fb4 [SPARK-33857][SQL] Unify the default seed of random functions
### What changes were proposed in this pull request?

Unify the seed of random functions
1. Add a hold place expression `UnresolvedSeed ` as the defualt seed.
2. Change `Rand`,`Randn`,`Uuid`,`Shuffle` default seed to `UnresolvedSeed `.
3. Replace `UnresolvedSeed ` to real seed at `ResolveRandomSeed` rule.

### Why are the changes needed?

`Uuid` and `Shuffle` use the `ResolveRandomSeed` rule to set the seed if user doesn't give a seed value. `Rand` and `Randn` do this at constructing.

It's better to unify the default seed at Analyzer side since we have used `ExpressionWithRandomSeed` at streaming query.

### Does this PR introduce _any_ user-facing change?

No.

gengjiaan 3e9821edfd [SPARK-33443][SQL] LEAD/LAG should support [ IGNORE NULLS | RESPECT NULLS ]
### What changes were proposed in this pull request?
The mainstream database support `[ IGNORE NULLS | RESPECT NULLS ]` for `LEAD`/`LAG`/`NTH_VALUE`/`FIRST_VALUE`/`LAST_VALUE`.
But the current implement of `LEAD`/`LAG` don't support this syntax.

Terry Kim f1d3797291 [SPARK-33886][SQL] UnresolvedTable should retain SQL text position for DDL commands
### What changes were proposed in this pull request?

Currently, there are many DDL commands where the position of the unresolved identifiers are incorrect:
```
scala> sql("MSCK REPAIR TABLE unknown")
org.apache.spark.sql.AnalysisException: Table not found: unknown; line 1 pos 0;
```
, whereas the `pos` should be 18.

This PR proposes to fix this issue for commands using `UnresolvedTable`:
```
MSCK REPAIR TABLE t
LOAD DATA LOCAL INPATH 'filepath' INTO TABLE t
TRUNCATE TABLE t
SHOW PARTITIONS t
ALTER TABLE t RECOVER PARTITIONS
ALTER TABLE t ADD PARTITION (p=1)
ALTER TABLE t PARTITION (p=1) RENAME TO PARTITION (p=2)
ALTER TABLE t DROP PARTITION (p=1)
ALTER TABLE t SET SERDEPROPERTIES ('a'='b')
COMMENT ON TABLE t IS 'hello'"
```

### Why are the changes needed?

To fix a bug.

### Does this PR introduce _any_ user-facing change?

Yes, now the above example will print the following:
```
org.apache.spark.sql.AnalysisException: Table not found: unknown; line 1 pos 18;
```

### How was this patch tested?

Add a new suite of tests.

Yuming Wang 7ffcfcf7db [SPARK-33847][SQL] Simplify CaseWhen if elseValue is None
### What changes were proposed in this pull request?

1. Enhance `ReplaceNullWithFalseInPredicate` to replace None of elseValue inside `CaseWhen` with `FalseLiteral` if all branches are `FalseLiteral` . The use case is:
```sql
create table t1 using parquet as select id from range(10);
explain select id from t1 where (CASE WHEN id = 1 THEN 'a' WHEN id = 3 THEN 'b' end) = 'c';
```

Before this pr:
```
== Physical Plan ==
*(1) Filter CASE WHEN (id#1L = 1) THEN false WHEN (id#1L = 3) THEN false END
+- *(1) ColumnarToRow
   +- FileScan parquet default.t1[id#1L] Batched: true, DataFilters: [CASE WHEN (id#1L = 1) THEN false WHEN (id#1L = 3) THEN false END], Format: Parquet, Location: InMemoryFileIndex[file:/Users/yumwang/opensource/spark/spark-warehouse/org.apache.spark.sql.DataF..., PartitionFilters: [], PushedFilters: [], ReadSchema: struct<id:bigint>

```

After this pr:
```
== Physical Plan ==
LocalTableScan <empty>, [id#1L]
```

2. Enhance `SimplifyConditionals` if elseValue is None and all outputs are null.

### Why are the changes needed?

Improve query performance.

### Does this PR introduce _any_ user-facing change?

No.

Max Gekk cc23581e26 [SPARK-33858][SQL][TESTS] Unify v1 and v2 ALTER TABLE .. RENAME PARTITION tests
### What changes were proposed in this pull request?
1. Move the `ALTER TABLE .. RENAME PARTITION` parsing tests to `AlterTableRenamePartitionParserSuite`
2. Place the v1 tests for `ALTER TABLE .. RENAME PARTITION` from `DDLSuite` to `v1.AlterTableRenamePartitionSuite` and v2 tests from `AlterTablePartitionV2SQLSuite` to `v2.AlterTableRenamePartitionSuite`, so, the tests will run for V1, Hive V1 and V2 DS.

### Why are the changes needed?
- The unification will allow to run common `ALTER TABLE .. RENAME PARTITION` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
By running new test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableRenamePartitionParserSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableRenamePartitionSuite"

### What changes were proposed in this pull request?
1. Add new methods `purgePartition()`/`purgePartitions()` to the interfaces `SupportsPartitionManagement`/`SupportsAtomicPartitionManagement`.
2. Default implementation of new methods throw the exception `UnsupportedOperationException`.
3. Add tests for new methods to `SupportsPartitionManagementSuite`/`SupportsAtomicPartitionManagementSuite`.
4. Add `ALTER TABLE .. DROP PARTITION` tests for DS v1 and v2.

Closes #30776
Closes #30821

### Why are the changes needed?
Currently, the `PURGE` option that user can set in `ALTER TABLE .. DROP PARTITION` is completely ignored. We should pass this flag to the catalog implementation, so, the catalog should decide how to handle the flag.

### Does this PR introduce _any_ user-facing change?
The changes can impact on behavior of `ALTER TABLE .. DROP PARTITION` for v2 tables.

### How was this patch tested?
By running the affected test suites, for instance:
```

ulysses-you e853f068f6 [SPARK-33526][SQL][FOLLOWUP] Fix flaky test due to timeout and fix docs
### What changes were proposed in this pull request?

### Why are the changes needed?

Query timeout sometime since we set an another config after set query timeout.
```
sbt.ForkMain$ForkError: java.sql.SQLTimeoutException: Query timed out after 0 seconds
	at org.apache.hive.jdbc.HiveStatement.waitForOperationToComplete(HiveStatement.java:381)
	at org.apache.hive.jdbc.HiveStatement.execute(HiveStatement.java:254)
	at org.apache.spark.sql.hive.thriftserver.ThriftServerWithSparkContextSuite.$anonfun$$init$$13(ThriftServerWithSparkContextSuite.scala:107)
	at org.apache.spark.sql.hive.thriftserver.ThriftServerWithSparkContextSuite.$anonfun$$init$$13$adapted(ThriftServerWithSparkContextSuite.scala:106)

	at org.apache.spark.sql.hive.thriftserver.SharedThriftServer.$anonfun$withJdbcStatement$4$adapted(SharedThriftServer.scala:95)
```

The reason is:
1. we execute `set spark.sql.thriftServer.queryTimeout = 1`, then all the option will be limited in 1s.
2. we execute `set spark.sql.thriftServer.interruptOnCancel = false/true`. This sql will get timeout exception if there is something hung within 1s. It's not our expected.

Reset the timeout before we do the step2 can avoid this problem.

Wenchen Fan ec1560af25 [SPARK-33364][SQL][FOLLOWUP] Refine the catalog v2 API to purge a table
### What changes were proposed in this pull request?

This is a followup of https://github.com/apache/spark/pull/30267

Inspired by https://github.com/apache/spark/pull/30886, it's better to have 2 methods `def dropTable` and `def purgeTable`, than `def dropTable(ident)` and `def dropTable(ident, purge)`.

### Why are the changes needed?

1. make the APIs orthogonal. Previously, `def dropTable(ident, purge)` calls `def dropTable(ident)` and is a superset.
2. simplifies the catalog implementation a little bit. Now the `if (purge) ... else ...` check is done at the Spark side.

### Does this PR introduce _any_ user-facing change?

No.

Erik Krogen 303b8c8773 [SPARK-23862][SQL] Support Java enums from Scala Dataset API
### What changes were proposed in this pull request?
Add support for Java Enums (`java.lang.Enum`) from the Scala typed Dataset APIs. This involves adding an implicit for `Encoder` creation in `SQLImplicits`, and updating `ScalaReflection` to handle Java Enums on the serialization and deserialization pathways.

Enums are mapped to a `StringType` which is just the name of the Enum value.

### Why are the changes needed?
In [SPARK-21255](https://issues.apache.org/jira/browse/SPARK-21255), support for (de)serialization of Java Enums was added, but only when called from Java code. It is common for Scala code to rely on Java libraries that are out of control of the Scala developer. Today, if there is a dependency on some Java code which defines an Enum, it would be necessary to define a corresponding Scala class. This change brings closer feature parity between Scala and Java APIs.

### Does this PR introduce _any_ user-facing change?
Yes, previously something like:
```
val ds = Seq(MyJavaEnum.VALUE1, MyJavaEnum.VALUE2).toDS
// or
val ds = Seq(CaseClass(MyJavaEnum.VALUE1), CaseClass(MyJavaEnum.VALUE2)).toDS
```
would fail. Now, it will succeed.

### How was this patch tested?
Additional unit tests are added in `DatasetSuite`. Tests include validating top-level enums, enums inside of case classes, enums inside of arrays, and validating that the Enum is stored as the expected string.

Closes #30877 from xkrogen/xkrogen-SPARK-23862-scalareflection-java-enums.

### What changes were proposed in this pull request?
This PR adds the length check to the existing ApplyCharPadding rule. Tables will have external locations when users execute
SET LOCATION or CREATE TABLE ... LOCATION. If the location contains over length values we should FAIL ON READ.

### Why are the changes needed?

```sql

### What changes were proposed in this pull request?

```scala
val nestedStruct = new StructType()
  .add(StructField("b", StringType).withComment("Nested comment"))
val struct = new StructType()
  .add(StructField("a", nestedStruct).withComment("comment"))

struct.toDDL
```

Currently, returns:
```
`a` STRUCT<`b`: STRING> COMMENT 'comment'`
```

With this PR, the code above returns:
```
`a` STRUCT<`b`: STRING COMMENT 'Nested comment'> COMMENT 'comment'`
```

### Why are the changes needed?

My team is using nested columns as first citizens, and I thought it would be nice to have comments for nested columns.

### Does this PR introduce _any_ user-facing change?

Now, when users call something like this,
```scala
spark.table("foo.bar").schema.fields.map(_.toDDL).mkString(", ")
```
they will get comments for the nested columns.

### How was this patch tested?

I added unit tests under `org.apache.spark.sql.types.StructTypeSuite`. They test if nested StructType's comment is included in the DDL string.

Yuming Wang 1c77605682 [SPARK-33848][SQL] Push the UnaryExpression into (if / case) branches
### What changes were proposed in this pull request?

This pr push the `UnaryExpression` into (if / case) branches. The use case is:
```sql
create table t1 using parquet as select id from range(10);
explain select id from t1 where (CASE WHEN id = 1 THEN '1' WHEN id = 3 THEN '2' end) > 3;
```

Before this pr:
```
== Physical Plan ==
*(1) Filter (cast(CASE WHEN (id#1L = 1) THEN 1 WHEN (id#1L = 3) THEN 2 END as int) > 3)
+- *(1) ColumnarToRow
   +- FileScan parquet default.t1[id#1L] Batched: true, DataFilters: [(cast(CASE WHEN (id#1L = 1) THEN 1 WHEN (id#1L = 3) THEN 2 END as int) > 3)], Format: Parquet, Location: InMemoryFileIndex[file:/Users/yumwang/opensource/spark/spark-warehouse/org.apache.spark.sql.DataF..., PartitionFilters: [], PushedFilters: [], ReadSchema: struct<id:bigint>

```

After this pr:
```
== Physical Plan ==
LocalTableScan <empty>, [id#1L]
```

This change can also improve this case:

Takeshi Yamamuro 69aa727ff4 [SPARK-33124][SQL] Fills missing group tags and re-categorizes all the group tags for built-in functions
### What changes were proposed in this pull request?

This PR proposes to fill missing group tags and re-categorize all the group tags for built-in functions.
New groups below are added in this PR:
 - binary_funcs
 - bitwise_funcs
 - collection_funcs
 - predicate_funcs
 - conditional_funcs
 - conversion_funcs
 - csv_funcs
 - generator_funcs
 - hash_funcs
 - lambda_funcs
 - math_funcs
 - misc_funcs
 - string_funcs
 - struct_funcs
 - xml_funcs

A basic policy to re-categorize functions is that functions in the same file are categorized into the same group. For example, all the functions in `hash.scala` are categorized into `hash_funcs`. But, there are some exceptional/ambiguous cases when categorizing them. Here are some special notes:
 - All the aggregate functions are categorized into `agg_funcs`.
 - `array_funcs` and `map_funcs` are  sub-groups of `collection_funcs`. For example, `array_contains` is used only for arrays, so it is assigned to `array_funcs`. On the other hand, `reverse` is used for both arrays and strings, so it is assigned to `collection_funcs`.
 - Some functions logically belong to multiple groups. In this case, these functions are categorized based on the file that they belong to. For example, `schema_of_csv` can be grouped into both `csv_funcs` and `struct_funcs` in terms of input types, but it is assigned to `csv_funcs` because it belongs to the `csvExpressions.scala` file that holds the other CSV-related functions.
 - Functions in `nullExpressions.scala`, `complexTypeCreator.scala`, `randomExpressions.scala`, and `regexExpressions.scala` are categorized based on their functionalities. For example:
   - `isnull` in `nullExpressions`  is assigned to `predicate_funcs` because this is a predicate function.
   - `array` in `complexTypeCreator.scala` is assigned to `array_funcs`based on its output type (The other functions in `array_funcs` are categorized based on their input types though).

A category list (after this PR) is as follows (the list below includes the exprs that already have a group tag in the current master):

Yuming Wang 4b19f49dd0 [SPARK-33845][SQL] Remove unnecessary if when trueValue and falseValue are foldable boolean types
### What changes were proposed in this pull request?

Improve `SimplifyConditionals`.
   Simplify `If(cond, TrueLiteral, FalseLiteral)` to `cond`.
   Simplify `If(cond, FalseLiteral, TrueLiteral)` to `Not(cond)`.

The use case is:
```sql
create table t1 using parquet as select id from range(10);
select if (id > 2, false, true) from t1;
```
Before this pr:
```

Wenchen Fan b4bea1aa89 [SPARK-28863][SQL][FOLLOWUP] Make sure optimized plan will not be re-analyzed
### What changes were proposed in this pull request?

It's a known issue that re-analyzing an optimized plan can lead to various issues. We made several attempts to avoid it from happening, but the current solution `AlreadyOptimized` is still not 100% safe, as people can inject catalyst rules to call analyzer directly.

This PR proposes a simpler and safer idea: we set the `analyzed` flag to true after optimization, and analyzer will skip processing plans whose `analyzed` flag is true.

### Why are the changes needed?

make the code simpler and safer

### Does this PR introduce _any_ user-facing change?

no

Max Gekk b313a1e9e6 [SPARK-33849][SQL][TESTS] Unify v1 and v2 DROP TABLE tests
### What changes were proposed in this pull request?
1. Move the `DROP TABLE` parsing tests to `DropTableParserSuite`
2. Place the v1 tests for `DROP TABLE` from `DDLSuite` and v2 tests from `DataSourceV2SQLSuite` to the common trait `DropTableSuiteBase`, so, the tests will run for V1, Hive V1 and V2 DS.

### Why are the changes needed?
- The unification will allow to run common `DROP TABLE` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
By running new test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *DropTableParserSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *DropTableSuite"

Terry Kim 1c7b79c057 [SPARK-33856][SQL] Migrate ALTER TABLE ... RENAME TO PARTITION to use UnresolvedTable to resolve the identifier
### What changes were proposed in this pull request?

This PR proposes to migrate `ALTER TABLE ... RENAME TO PARTITION` to use `UnresolvedTable` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

Note that `ALTER TABLE ... RENAME TO PARTITION` is not supported for v2 tables.

### Why are the changes needed?

The PR makes the resolution consistent behavior consistent. For example,
```
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint, val string) USING csv PARTITIONED BY (id)")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE spark_catalog.test")
sql("ALTER TABLE t PARTITION (id=1) RENAME TO PARTITION (id=2)") // works fine assuming id=1 exists.
```
, but after this PR:
```
sql("ALTER TABLE t PARTITION (id=1) RENAME TO PARTITION (id=2)")
org.apache.spark.sql.AnalysisException: t is a temp view. 'ALTER TABLE ... RENAME TO PARTITION' expects a table; line 1 pos 0
```
, which is the consistent behavior with other commands.

### Does this PR introduce _any_ user-facing change?

After this PR, `ALTER TABLE` in the above example is resolved to a temp view `t` first instead of `spark_catalog.test.t`.

### How was this patch tested?

Updated existing tests.

Wenchen Fan de234eec8f [SPARK-33812][SQL] Split the histogram column stats when saving to hive metastore as table property
### What changes were proposed in this pull request?

Hive metastore has a limitation for the table property length. To work around it, Spark split the schema json string into several parts when saving to hive metastore as table properties. We need to do the same for histogram column stats as it can go very big.

This PR refactors the table property splitting code, so that we can share it between the schema json string and histogram column stats.

### Why are the changes needed?

To be able to analyze table when histogram data is big.

### Does this PR introduce _any_ user-facing change?

no

### What changes were proposed in this pull request?
There are a lot of mainstream databases support regex function `REGEXP_LIKE`.
Currently, Spark supports `RLike` and we just need add a new alias `REGEXP_LIKE` for it.
**Oracle**

**Snowflake**
https://docs.snowflake.com/en/sql-reference/functions/regexp_like.html

**Additional modifications**

1. Because test case named `check outputs of expression examples` in ExpressionInfoSuite executes the example SQL of built-in function, so the below SQL be executed:
`SELECT '%SystemDrive%\Users\John' regexp_like '%SystemDrive%\\Users.*'`
But Spark SQL not supports this syntax yet.
2. Another reason: `SELECT '%SystemDrive%\Users\John' _FUNC_ '%SystemDrive%\\Users.*';`  is an SQL syntax, not the usecase for function `RLike`.
As the above reason, this PR changes the example SQL of `RLike`.

### Why are the changes needed?
No

### Does this PR introduce _any_ user-facing change?
Make the behavior of Spark SQL consistent with mainstream databases.

### How was this patch tested?
Jenkins test

Terry Kim 0f1a18370a [SPARK-33817][SQL] CACHE TABLE uses a logical plan when caching a query to avoid creating a dataframe
### What changes were proposed in this pull request?

This PR proposes to update `CACHE TABLE` to use a `LogicalPlan` when caching a query to avoid creating a `DataFrame` as suggested here: https://github.com/apache/spark/pull/30743#discussion_r543123190

For reference, `UNCACHE TABLE` also uses `LogicalPlan`: 0c12900120/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/v2/CacheTableExec.scala (L91-L98)

### Why are the changes needed?

To avoid creating an unnecessary dataframe and make it consistent with `uncacheQuery` used in `UNCACHE TABLE`.

### Does this PR introduce _any_ user-facing change?

No, just internal changes.

### How was this patch tested?

Kent Yao 728a1298af [SPARK-33806][SQL] limit partition num to 1 when distributing by foldable expressions
### What changes were proposed in this pull request?

It seems a very popular way that people use DISTRIBUTE BY clause with a literal to coalesce partition in the pure SQL data processing.

For example
```
insert into table src select * from values (1), (2), (3) t(a) distribute by 1
```

Users may want the final output to be one single data file, but if the reality is not always true. Spark will always create a file for partition 0 whether it contains data or not, so when the data all goes to a partition(IDX >0), there will be always 2 files there and the part-00000 is empty. On the other hand, a lot of empty tasks will be launched too, this is unnecessary.

When users repeat the insert statement daily, hourly, or minutely, it causes small file issues.

```
spark-sql> set spark.sql.shuffle.partitions=3;drop table if exists test2;create table test2 using parquet as select * from values (1), (2), (3) t(a) distribute by 1;

To avoid this, there are some options you can take.

1. use `distribute by null`, let the data go to the partition 0
2. set spark.sql.adaptive.enabled to true for Spark to automatically coalesce
3. using hints instead of `distribute by`
4. set spark.sql.shuffle.partitions to 1

In this PR, we set the partition number to 1 in this particular case.

### Why are the changes needed?

1. avoid small file issues
2. avoid unnecessary empty tasks when no adaptive execution

### Does this PR introduce _any_ user-facing change?

Terry Kim 8666d1c39c [SPARK-33800][SQL] Remove command name in AnalysisException message when a relation is not resolved
### What changes were proposed in this pull request?

Based on the discussion https://github.com/apache/spark/pull/30743#discussion_r543124594, this PR proposes to remove the command name in AnalysisException message when a relation is not resolved.

For some of the commands that use `UnresolvedTable`, `UnresolvedView`, and `UnresolvedTableOrView` to resolve an identifier, when the identifier cannot be resolved, the exception will be something like `Table or view not found for 'SHOW TBLPROPERTIES': badtable`. The command name (`SHOW TBLPROPERTIES` in this case) should be dropped to be consistent with other existing commands.

### Why are the changes needed?

To make the exception message consistent.

### Does this PR introduce _any_ user-facing change?

Yes, the exception message will be changed from
```
Table or view not found for 'SHOW TBLPROPERTIES': badtable
```
to
```
Table or view not found: badtable
```
for commands that use `UnresolvedTable`, `UnresolvedView`, and `UnresolvedTableOrView` to resolve an identifier.

### How was this patch tested?

Updated existing tests.

Kent Yao 205d8e40bc [SPARK-32991][SQL] [FOLLOWUP] Reset command relies on session initials first
### What changes were proposed in this pull request?

As a follow-up of https://github.com/apache/spark/pull/30045, we modify the RESET command here to respect the session initial configs per session first then fall back to the `SharedState` conf, which makes each session could maintain a different copy of initial configs for resetting.

### Why are the changes needed?

to make reset command saner.
### Does this PR introduce _any_ user-facing change?

yes, RESET will respect session initials first not always go to the system defaults

HyukjinKwon 7845865b8d [SPARK-33803][SQL] Sort table properties by key in DESCRIBE TABLE command
### What changes were proposed in this pull request?

This PR proposes to sort table properties in DESCRIBE TABLE command. This is consistent with DSv2 command as well:
e3058ba17c/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/v2/DescribeTableExec.scala (L63)

This PR fixes the test case in Scala 2.13 build as well where the table properties have different order in the map.

### Why are the changes needed?

To keep the deterministic and pretty output, and fix the tests in Scala 2.13 build.
See https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-maven-hadoop-3.2-scala-2.13/49/testReport/junit/org.apache.spark.sql/SQLQueryTestSuite/describe_sql/

```
describe.sql&#010;Expected "...spark_catalog, view.[query.out.col.2=c, view.referredTempFunctionsNames=[], view.catalogAndNamespace.part.1=default]]", but got "...spark_catalog, view.[catalogAndNamespace.part.1=default, view.query.out.col.2=c, view.referredTempFunctionsNames=[]]]" Result did not match for query #29&#010;DESC FORMATTED v
```

### Does this PR introduce _any_ user-facing change?

Yes, it will change the text output from `DESCRIBE [EXTENDED|FORMATTED] table_name`.
Now the table properties are sorted by its key.

### How was this patch tested?

Related unittests were fixed accordingly.

Max Gekk 141e26d65b [SPARK-33767][SQL][TESTS] Unify v1 and v2 ALTER TABLE .. DROP PARTITION tests
### What changes were proposed in this pull request?
1. Move the `ALTER TABLE .. DROP PARTITION` parsing tests to `AlterTableDropPartitionParserSuite`
2. Place v1 tests for `ALTER TABLE .. DROP PARTITION` from `DDLSuite` and v2 tests from `AlterTablePartitionV2SQLSuite` to the common trait `AlterTableDropPartitionSuiteBase`, so, the tests will run for V1, Hive V1 and V2 DS.

### Why are the changes needed?
- The unification will allow to run common `ALTER TABLE .. DROP PARTITION` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
By running new test suites:
```

Terry Kim 366beda54a [SPARK-33785][SQL] Migrate ALTER TABLE ... RECOVER PARTITIONS to use UnresolvedTable to resolve the identifier
### What changes were proposed in this pull request?

This PR proposes to migrate `ALTER TABLE ... RECOVER PARTITIONS` to use `UnresolvedTable` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

Note that `ALTER TABLE ... RECOVER PARTITIONS` is not supported for v2 tables.

### Why are the changes needed?

The PR makes the resolution consistent behavior consistent. For example,
```scala
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint, val string) USING csv PARTITIONED BY (id)")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE spark_catalog.test")
sql("ALTER TABLE t RECOVER PARTITIONS") // works fine
```
, but after this PR:
```
sql("ALTER TABLE t RECOVER PARTITIONS")
org.apache.spark.sql.AnalysisException: t is a temp view. 'ALTER TABLE ... RECOVER PARTITIONS' expects a table; line 1 pos 0
```
, which is the consistent behavior with other commands.

### Does this PR introduce _any_ user-facing change?

After this PR, `ALTER TABLE t RECOVER PARTITIONS` in the above example is resolved to a temp view `t` first instead of `spark_catalog.test.t`.

### How was this patch tested?

Updated existing tests.

Anton Okolnychyi 82aca7eb8f [SPARK-33779][SQL] DataSource V2: API to request distribution and ordering on write
### What changes were proposed in this pull request?

This PR adds connector interfaces proposed in the [design doc](https://docs.google.com/document/d/1X0NsQSryvNmXBY9kcvfINeYyKC-AahZarUqg3nS1GQs/edit#) for SPARK-23889.

**Note**: This PR contains a subset of changes discussed in PR #29066.

### Why are the changes needed?

Data sources should be able to request a specific distribution and ordering of data on write. In particular, these scenarios are considered useful:
- global sort
- cluster data and sort within partitions
- local sort within partitions
- no sort

Please see the design doc above for a more detailed explanation of requirements.

### Does this PR introduce _any_ user-facing change?

This PR introduces public changes to the DS V2 by adding a logical write abstraction as we have on the read path as well as additional interfaces to represent distribution and ordering of data (please see the doc for more info).

The existing `Distribution` interface in `read` package is read-specific and not flexible enough like discussed in the design doc. The current proposal is to evolve these interfaces separately until they converge.

### How was this patch tested?

This patch adds only interfaces.

### What changes were proposed in this pull request?

The deterministic field is wider than `NonDerterministic`, we should keep same range between pull out and check analysis.

### Why are the changes needed?

For example
```
select * from values(1), (4) as t(c1) order by java_method('java.lang.Math', 'abs', c1)
```

We will get exception since `java_method` deterministic field is false but not a `NonDeterministic`

Terry Kim a84c8d842c [SPARK-33751][SQL] Migrate ALTER VIEW ... AS command to use UnresolvedView to resolve the identifier
### What changes were proposed in this pull request?

This PR migrates `ALTER VIEW ... AS` to use `UnresolvedView` to resolve the view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

The `TempViewOrV1Table` extractor in `ResolveSessionCatalog.scala` can now be removed as well.

### Why are the changes needed?

To use `UnresolvedView` for view resolution.

### Does this PR introduce _any_ user-facing change?

The exception message changes if a table is found instead of view:
```
// OLD
`tab1` is not a view"
```
```
// NEW
"tab1 is a table. 'ALTER VIEW ... AS' expects a view."
```

### How was this patch tested?

Updated existing tests.

xuewei.linxuewei e7fe92f129 [SPARK-33546][SQL] Enable row format file format validation in CREATE TABLE LIKE
### What changes were proposed in this pull request?

[SPARK-33546] stated the there are three inconsistency behaviors for CREATE TABLE LIKE.

1. CREATE TABLE LIKE does not validate the user-specified hive serde. e.g., STORED AS PARQUET can't be used with ROW FORMAT SERDE.
2. CREATE TABLE LIKE requires STORED AS and ROW FORMAT SERDE to be specified together, which is not necessary.
3. CREATE TABLE LIKE does not respect the default hive serde.

This PR fix No.1, and after investigate, No.2 and No.3 turn out not to be issue.

Within Hive.

CREATE TABLE abc ... ROW FORMAT SERDE 'xxx.xxx.SerdeClass' (Without Stored as) will have
following result. Using the user specific SerdeClass and fetch default input/output format from default textfile format.

```
SerDe Library:          xxx.xxx.SerdeClass
InputFormat:            org.apache.hadoop.mapred.TextInputFormat
OutputFormat:           org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat
```

But for
CREATE TABLE dst LIKE src ROW FORMAT SERDE 'xxx.xxx.SerdeClass' (Without Stored as) will just ignore user specific SerdeClass and using (input, output, serdeClass) from src table.

It's better to just throw an exception on such ambiguous behavior, so No.2 is not an issue, but in the PR, we add some comments.

For No.3, in fact, CreateTableLikeCommand is using following logical to try to follow src table's storageFormat if current fileFormat.inputFormat is empty

```
val newStorage = if (fileFormat.inputFormat.isDefined) {
      fileFormat
    } else {
      sourceTableDesc.storage.copy(locationUri = fileFormat.locationUri)
    }
```

If we try to fill the new target table with HiveSerDe.getDefaultStorage if file format and row format is not explicity spefified, it will break the CREATE TABLE LIKE semantic.

### Why are the changes needed?

### Does this PR introduce any user-facing change?

No.

### How was this patch tested?

Max Gekk 817f58ddcb [SPARK-33768][SQL] Remove retainData from AlterTableDropPartition
### What changes were proposed in this pull request?
Remove the `retainData` parameter from the logical node `AlterTableDropPartition`.

### Why are the changes needed?
The `AlterTableDropPartition` command reflects the sql statement (see SqlBase.g4):
```
    | ALTER (TABLE | VIEW) multipartIdentifier
        DROP (IF EXISTS)? partitionSpec (',' partitionSpec)* PURGE?    #dropTablePartitions
```
but Spark doesn't allow to specify data retention. So, the parameter can be removed to improve code maintenance.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
By running the test suite `DDLParserSuite`.

Max Gekk 9160d59ae3 [SPARK-33770][SQL][TESTS] Fix the ALTER TABLE .. DROP PARTITION tests that delete files out of partition path
### What changes were proposed in this pull request?
Modify the tests that add partitions with `LOCATION`, and where the number of nested folders in `LOCATION` doesn't match to the number of partitioned columns. In that case, `ALTER TABLE .. DROP PARTITION` tries to access (delete) folder out of the "base" path in `LOCATION`.

The problem belongs to Hive's MetaStore method `drop_partition_common`:
8696c82d07/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java (L4876)
which tries to delete empty partition sub-folders recursively starting from the most deeper partition sub-folder up to the base folder. In the case when the number of sub-folder is not equal to the number of partitioned columns `part_vals.size()`, the method will try to list and delete folders out of the base path.

### Why are the changes needed?
To fix test failures like https://github.com/apache/spark/pull/30643#issuecomment-743774733:
```
org.apache.spark.sql.hive.execution.command.AlterTableAddPartitionSuite.ALTER TABLE .. ADD PARTITION Hive V1: SPARK-33521: universal type conversions of partition values

	at sun.reflect.GeneratedMethodAccessor304.invoke(Unknown Source)
```

The issue can be reproduced by the following steps:
1. Create a base folder, for example: `/Users/maximgekk/tmp/part-location`
2. Create a sub-folder in the base folder and drop permissions for it:
```
$ mkdir /Users/maximgekk/tmp/part-location/aaa
$ chmod a-rwx chmod a-rwx /Users/maximgekk/tmp/part-location/aaa
$ ls -al /Users/maximgekk/tmp/part-location
total 0
drwxr-xr-x   3 maximgekk  staff    96 Dec 13 18:42 .
drwxr-xr-x  33 maximgekk  staff  1056 Dec 13 18:32 ..
d---------   2 maximgekk  staff    64 Dec 13 18:42 aaa
```
3. Create a table with a partition folder in the base folder:
```sql
spark-sql> create table tbl (id int) partitioned by (part0 int, part1 int);
spark-sql> alter table tbl add partition (part0=1,part1=2) location '/Users/maximgekk/tmp/part-location/tbl';
```
4. Try to drop this partition:
```
spark-sql> alter table tbl drop partition (part0=1,part1=2);
20/12/13 18:46:07 ERROR HiveClientImpl:
======================
Attempt to drop the partition specs in table 'tbl' database 'default':
Map(part0 -> 1, part1 -> 2)
In this attempt, the following partitions have been dropped successfully:

The remaining partitions have not been dropped:
[1, 2]
======================

Error in query: org.apache.hadoop.hive.ql.metadata.HiveException: Error accessing file:/Users/maximgekk/tmp/part-location/aaa;
org.apache.spark.sql.AnalysisException: org.apache.hadoop.hive.ql.metadata.HiveException: Error accessing file:/Users/maximgekk/tmp/part-location/aaa;
```
The command fails because it tries to access to the sub-folder `aaa` that is out of the partition path `/Users/maximgekk/tmp/part-location/tbl`.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
By running the affected tests from local IDEA which does not have access to folders out of partition paths.

This PR add a new config `spark.sql.thriftServer.forceCancel` to give user a way to interrupt task when cancel statement.

### Why are the changes needed?

After [#29933](https://github.com/apache/spark/pull/29933), we support cancel query if timeout, but the default behavior of `SparkContext.cancelJobGroups` won't interrupt task and just let task finish by itself. In some case it's dangerous, e.g., data skew or exists a heavily shuffle. A task will hold in a long time after do cancel and the resource will not release.

Max Gekk 8b97b19ffa [SPARK-33706][SQL] Require fully specified partition identifier in partitionExists()
### What changes were proposed in this pull request?
1. Check that the partition identifier passed to `SupportsPartitionManagement.partitionExists()` is fully specified (specifies all values of partition fields).
2. Remove the custom implementation of `partitionExists()` from `InMemoryPartitionTable`, and re-use the default implementation from `SupportsPartitionManagement`.

### Why are the changes needed?
The method is supposed to check existence of one partition but currently it can return `true` for partially specified partition. This can lead to incorrect commands behavior, for instance the commands could modify or place data in the middle of partition path.

Terry Kim b112e2bfa6 [SPARK-33714][SQL] Migrate ALTER VIEW ... SET/UNSET TBLPROPERTIES commands to use UnresolvedView to resolve the identifier
### What changes were proposed in this pull request?

This PR adds `allowTemp` flag to `UnresolvedView` so that `Analyzer` can check whether to resolve temp views or not.

This PR also migrates `ALTER VIEW ... SET/UNSET TBLPROPERTIES` to use `UnresolvedView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

### Why are the changes needed?

To use `UnresolvedView` for view resolution.

One benefit is that the exception message is better for `ALTER VIEW ... SET/UNSET TBLPROPERTIES`. Before, if a temp view is passed, you will just get `NoSuchTableException` with `Table or view 'tmpView' not found in database 'default'`. But with this PR, you will get more description exception message: `tmpView is a temp view. ALTER VIEW ... SET TBLPROPERTIES expects a permanent view`.

### Does this PR introduce _any_ user-facing change?

The exception message changes as describe above.

### How was this patch tested?

Updated existing tests.

Max Gekk af37c7f411 [SPARK-33558][SQL][TESTS] Unify v1 and v2 ALTER TABLE .. ADD PARTITION tests
### What changes were proposed in this pull request?
1. Move the `ALTER TABLE .. ADD PARTITION` parsing tests to `AlterTableAddPartitionParserSuite`
2. Place v1 tests for `ALTER TABLE .. ADD PARTITION` from `DDLSuite` and v2 tests from `AlterTablePartitionV2SQLSuite` to the common trait `AlterTableAddPartitionSuiteBase`, so, the tests will run for V1, Hive V1 and V2 DS.

### Why are the changes needed?
- The unification will allow to run common `ALTER TABLE .. ADD PARTITION` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
By running new test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableAddPartitionSuite"
```

Terry Kim 29fed23ba1 [SPARK-33703][SQL] Migrate MSCK REPAIR TABLE to use UnresolvedTable to resolve the identifier
### What changes were proposed in this pull request?

This PR proposes to migrate `MSCK REPAIR TABLE` to use `UnresolvedTable` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

Note that `MSCK REPAIR TABLE` is not supported for v2 tables.

### Why are the changes needed?

The PR makes the resolution consistent behavior consistent. For example,
```scala
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint, val string) USING csv PARTITIONED BY (id)")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE spark_catalog.test")
sql("MSCK REPAIR TABLE t") // works fine
```
, but after this PR:
```
sql("MSCK REPAIR TABLE t")
org.apache.spark.sql.AnalysisException: t is a temp view. 'MSCK REPAIR TABLE' expects a table; line 1 pos 0
```
, which is the consistent behavior with other commands.

### Does this PR introduce _any_ user-facing change?

After this PR, `MSCK REPAIR TABLE t` in the above example is resolved to a temp view `t` first instead of `spark_catalog.test.t`.

### How was this patch tested?

Updated existing tests.

[SPARK-32110][SQL] normalize special floating numbers in HyperLogLog++
### What changes were proposed in this pull request?

Currently, Spark treats 0.0 and -0.0 semantically equal, while it still retains the difference between them so that users can see -0.0 when displaying the data set.

The comparison expressions in Spark take care of the special floating numbers and implement the correct semantic. However, Spark doesn't always use these comparison expressions to compare values, and we need to normalize the special floating numbers before comparing them in these places:
1. GROUP BY
2. join keys
3. window partition keys

This PR fixes one more place that compares values without using comparison expressions: HyperLogLog++

### Why are the changes needed?

Fix the query result

### Does this PR introduce _any_ user-facing change?

Yes, the result of HyperLogLog++ becomes correct now.

### How was this patch tested?

a new test case, and a few more test cases that pass before this PR to improve test coverage.

Terry Kim c05ee06f5b [SPARK-33685][SQL] Migrate DROP VIEW command to use UnresolvedView to resolve the identifier
### What changes were proposed in this pull request?

This PR introduces `UnresolvedView` in the resolution framework to resolve the identifier.

This PR then migrates `DROP VIEW` to use `UnresolvedView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

### What changes were proposed in this pull request?
1. Remove old statement `ShowTableStatement`
2. Introduce new command `ShowTableExtended` for  `SHOW TABLE EXTENDED`.

This PR is the first step of new V2 implementation of `SHOW TABLE EXTENDED`, see SPARK-33393.

### Why are the changes needed?
This is a part of effort to make the relation lookup behavior consistent: SPARK-29900.

### Does this PR introduce _any_ user-facing change?
The changes should not affect V1 tables. For V2, Spark outputs the error:
```
SHOW TABLE EXTENDED is not supported for v2 tables.

Max Gekk 26c0493318 [SPARK-33676][SQL] Require exact matching of partition spec to the schema in V2 ALTER TABLE .. ADD/DROP PARTITION
### What changes were proposed in this pull request?
Check that partitions specs passed to v2 `ALTER TABLE .. ADD/DROP PARTITION` exactly match to the partition schema (all partition fields from the schema are specified in partition specs).

### Why are the changes needed?
1. To have the same behavior as V1 `ALTER TABLE .. ADD/DROP PARTITION` that output the error:
```sql
spark-sql> create table tab1 (id int, a int, b int) using parquet partitioned by (a, b);
spark-sql> ALTER TABLE tab1 ADD PARTITION (A='9');
Error in query: Partition spec is invalid. The spec (a) must match the partition spec (a, b) defined in table '`default`.`tab1`';
```
2. To prevent future errors caused by not fully specified partition specs.

### Does this PR introduce _any_ user-facing change?
Yes. The V2 implementation of `ALTER TABLE .. ADD/DROP PARTITION` output the same error as V1 commands.

### How was this patch tested?
By running the test suite with new UT:
```
$ build/sbt "test:testOnly *AlterTablePartitionV2SQLSuite"
```

[SPARK-33652][SQL] DSv2: DeleteFrom should refresh cache
### What changes were proposed in this pull request?

This changes `DeleteFromTableExec` to also refresh caches referencing the original table, by passing the `refreshCache` callback to the class. Note that in order to construct the callback, I have to change `DataSourceV2ScanRelation` to contain a `DataSourceV2Relation` instead of a `Table`.

### Why are the changes needed?

Currently DSv2 delete from table doesn't refresh caches. This could lead to correctness issue if the staled cache is queried later.

### Does this PR introduce _any_ user-facing change?

Yes. Now delete from table in v2 also refreshes cache.

### How was this patch tested?

[SPARK-33651][SQL] Allow CREATE EXTERNAL TABLE with LOCATION for data source tables
### What changes were proposed in this pull request?

This PR removes the restriction and allows CREATE EXTERNAL TABLE with LOCATION for data source tables. It also moves the check from the analyzer rule `ResolveSessionCatalog` to `SessionCatalog`, so that v2 session catalog can overwrite it.

### Why are the changes needed?

It's an unnecessary behavior difference that Hive serde table can be created with `CREATE EXTERNAL TABLE` if LOCATION is present, while data source table doesn't allow `CREATE EXTERNAL TABLE` at all.

### Does this PR introduce _any_ user-facing change?

Yes, now `CREATE EXTERNAL TABLE ... USING ... LOCATION ...` is allowed.

Jungtaek Lim (HeartSaVioR) 233a8494c8 [SPARK-27237][SS] Introduce State schema validation among query restart
## What changes were proposed in this pull request?

Please refer the description of [SPARK-27237](https://issues.apache.org/jira/browse/SPARK-27237) to see rationalization of this patch.

This patch proposes to introduce state schema validation, via storing key schema and value schema to `schema` file (for the first time) and verify new key schema and value schema for state are compatible with existing one. To be clear for definition of "compatible", state schema is "compatible" when number of fields are same and data type for each field is same - Spark has been allowing rename of field.

This patch will prevent query run which has incompatible state schema, which would reduce the chance to get indeterministic behavior (actually renaming of field is also the smell of semantically incompatible, but end users could just modify its name so we can't say) as well as providing more informative error message.

## How was this patch tested?

Added UTs.

Closes #24173 from HeartSaVioR/SPARK-27237.

### What changes were proposed in this pull request?
Currently, in spark, the temp view is saved as its analyzed logical plan, while the permanent view
is kept in HMS with its origin SQL text. As a result, permanent and temporary views have

Max Gekk 85949588b7 [SPARK-33650][SQL] Fix the error from ALTER TABLE .. ADD/DROP PARTITION for non-supported partition management table
### What changes were proposed in this pull request?
In the PR, I propose to change the order of post-analysis checks for the `ALTER TABLE .. ADD/DROP PARTITION` command, and perform the general check (does the table support partition management at all) before specific checks.

### Why are the changes needed?
The error message for the table which doesn't support partition management can mislead users:
```java
PartitionSpecs are not resolved;;
'AlterTableAddPartition [UnresolvedPartitionSpec(Map(id -> 1),None)], false
+- ResolvedTable org.apache.spark.sql.connector.InMemoryTableCatalog2fd64b11, ns1.ns2.tbl, org.apache.spark.sql.connector.InMemoryTable5d3ff859
```
because it says nothing about the root cause of the issue.

### Does this PR introduce _any_ user-facing change?
Yes. After the change, the error message will be:
```

```

[SPARK-33623][SQL] Add canDeleteWhere to SupportsDelete
### What changes were proposed in this pull request?

This PR provides us with a way to check if a data source is going to reject the delete via `deleteWhere` at planning time.

### Why are the changes needed?

The only way to support delete statements right now is to implement ``SupportsDelete``. According to its Javadoc, that interface is meant for cases when we can delete data without much effort (e.g. like deleting a complete partition in a Hive table).

This PR actually provides us with a way to check if a data source is going to reject the delete via `deleteWhere` at planning time instead of just getting an exception during execution. In the future, we can use this functionality to decide whether Spark should rewrite this delete and execute a distributed query or it can just pass a set of filters.

Consider an example of a partitioned Hive table. If we have a delete predicate like `part_col = '2020'`, we can just drop the matching partition to satisfy this delete. In this case, the data source should return `true` from `canDeleteWhere` and use the filters it accepts in `deleteWhere` to drop the partition. I consider this as a delete without significant effort. At the same time, if we have a delete predicate like `id = 10`, Hive tables would not be able to execute this delete using a metadata only operation without rewriting files. In that case, the data source should return `false` from `canDeleteWhere` and we should use a more sophisticated row-level API to find out which records should be removed (the API is yet to be discussed, but we need this PR as a basis).

If we decide to support subqueries and all delete use cases by simply extending the existing API, this will mean all data sources will have to implement a lot of Spark logic to determine which records changed. I don't think we want to go that way as the Spark logic to determine which records should be deleted is independent of the underlying data source. So the assumption is that Spark will execute a plan to find which records must be deleted for data sources that return `false` from `canDeleteWhere`.
### Does this PR introduce _any_ user-facing change?

Yes but it is backward compatible.

Wenchen Fan 0706e64c49 [SPARK-30098][SQL] Add a configuration to use default datasource as provider for CREATE TABLE command
### What changes were proposed in this pull request?

For CRETE TABLE [AS SELECT] command, creates native Parquet table if neither USING nor STORE AS is specified and `spark.sql.legacy.createHiveTableByDefault` is false.

This is a retry after we unify the CREATE TABLE syntax. It partially reverts d2bec5e265

This PR allows `CREATE EXTERNAL TABLE` when `LOCATION` is present. This was not allowed for data source tables before, which is an unnecessary behavior different with hive tables.

### Why are the changes needed?

Changing from Hive text table to native Parquet table has many benefits:
1. be consistent with `DataFrameWriter.saveAsTable`.
2. better performance
3. better support for nested types (Hive text table doesn't work well with nested types, e.g. `insert into t values struct(null)` actually inserts a null value not `struct(null)` if `t` is a Hive text table, which leads to wrong result)
4. better interoperability as Parquet is a more popular open file format.

### Does this PR introduce _any_ user-facing change?

No by default. If the config is set, the behavior change is described below:

Behavior-wise, the change is very small as the native Parquet table is also Hive-compatible. All the Spark DDL commands that works for hive tables also works for native Parquet tables, with two exceptions: `ALTER TABLE SET [SERDE | SERDEPROPERTIES]` and `LOAD DATA`.

char/varchar behavior has been taken care by https://github.com/apache/spark/pull/30412, and there is no behavior difference between data source and hive tables.

One potential issue is `CREATE TABLE ... LOCATION ...` while users want to directly access the files later. It's more like a corner case and the legacy config should be good enough.

Another potential issue is users may use Spark to create the table and then use Hive to add partitions with different serde. This is not allowed for Spark native tables.

### How was this patch tested?

Re-enable the tests

### What changes were proposed in this pull request?

Add new functions DATE_FROM_UNIX_DATE and UNIX_DATE for conversion between Date type and Numeric types.

### Why are the changes needed?

2. We have introduced new functions from Bigquery for conversion between Timestamp type and Numeric types: TIMESTAMP_SECONDS, TIMESTAMP_MILLIS, TIMESTAMP_MICROS , UNIX_SECONDS, UNIX_MILLIS, and UNIX_MICROS. It makes sense to add functions for conversion between Date type and Numeric types as well.

yi.wu a082f4600b [SPARK-33071][SPARK-33536][SQL] Avoid changing dataset_id of LogicalPlan in join() to not break DetectAmbiguousSelfJoin
### What changes were proposed in this pull request?

Currently, `join()` uses `withPlan(logicalPlan)` for convenient to call some Dataset functions. But it leads to the `dataset_id` inconsistent between the `logicalPlan` and the original `Dataset`(because `withPlan(logicalPlan)` will create a new Dataset with the new id and reset the `dataset_id` with the new id of the `logicalPlan`). As a result, it breaks the rule `DetectAmbiguousSelfJoin`.

In this PR, we propose to drop the usage of `withPlan` but use the `logicalPlan` directly so its `dataset_id` doesn't change.

Besides, this PR also removes related metadata (`DATASET_ID_KEY`,  `COL_POS_KEY`) when an `Alias` tries to construct its own metadata. Because the `Alias` is no longer a reference column after converting to an `Attribute`.  To achieve that, we add a new field, `deniedMetadataKeys`, to indicate the metadata that needs to be removed.

### Why are the changes needed?

For the query below, it returns the wrong result while it should throws ambiguous self join exception instead:

```scala
val emp1 = Seq[TestData](
  TestData(1, "sales"),
  TestData(2, "personnel"),
  TestData(3, "develop"),
  TestData(4, "IT")).toDS()
val emp2 = Seq[TestData](
  TestData(1, "sales"),
  TestData(2, "personnel"),
  TestData(3, "develop")).toDS()
val emp3 = emp1.join(emp2, emp1("key") === emp2("key")).select(emp1("*"))
emp1.join(emp3, emp1.col("key") === emp3.col("key"), "left_outer")
  .select(emp1.col("*"), emp3.col("key").as("e2")).show()

// wrong result

### What changes were proposed in this pull request?

This PR is a followup of https://github.com/apache/spark/pull/30504. It proposes:

- Rename `NoSideEffect` to `NoThrow`, and use `Expression.deterministic` together where it is used.
- Clarify, in the docs in the expressions, that it means they don't throw exceptions

### Why are the changes needed?

`NoSideEffect` virtually means that `Expression.eval` does not throw an exception, and the expressions are deterministic.
It's best to be explicit so `NoThrow` was proposed -  I looked if there's a similar name to represent this concept and borrowed the name of [nothrow](https://clang.llvm.org/docs/AttributeReference.html#nothrow).
For determinism, we already have a way to note it under `Expression.deterministic`.

Cheng Su 51ebcd95a5 [SPARK-32863][SS] Full outer stream-stream join
### What changes were proposed in this pull request?

This PR is to add full outer stream-stream join, and the implementation of full outer join is:
* For left side input row, check if there's a match on right side state store.
  * if there's a match, output the joined row, o.w. output nothing. Put the row in left side state store.
* For right side input row, check if there's a match on left side state store.
  * if there's a match, output the joined row, o.w. output nothing. Put the row in right side state store.
* State store eviction: evict rows from left/right side state store below watermark, and output rows never matched before (a combination of left outer and right outer join).

### Why are the changes needed?

Enable more use cases for spark stream-stream join.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Added unit tests in `UnsupportedOperationChecker.scala` and `StreamingJoinSuite.scala`.

Closes #30395 from c21/stream-foj.

Thomas Graves f71f34572d [SPARK-33544][SQL] Optimize size of CreateArray/CreateMap to be the size of its children
### What changes were proposed in this pull request?

https://issues.apache.org/jira/browse/SPARK-32295 added in an optimization to insert a filter for not null and size > 0 when using inner explode/inline. This is fine in most cases but the extra filter is not needed if the explode is with a create array and not using Literals (it already handles LIterals).  When this happens you know that the values aren't null and it has a size.  It already handles the empty array.

The not null check is already optimized out because Createarray and createMap are not nullable, that leaves the size > 0 check. To handle that this PR makes it so that the size > 0 check gets optimized in ConstantFolding to be the size of the children in the array or map.  That makes it a literal and then makes it ultimately be optimized out.

### Why are the changes needed?
remove unneeded filter

### Does this PR introduce _any_ user-facing change?
no

### How was this patch tested?
Unit tests added and manually tested various cases

[SPARK-33612][SQL] Add dataSourceRewriteRules batch to Optimizer
### What changes were proposed in this pull request?

This PR adds a new batch to the optimizer for executing rules that rewrite plans for data sources.

### Why are the changes needed?

Right now, we have a special place in the optimizer where we construct v2 scans. As time shows, we need more rewrite rules that would be executed after the operator optimization and before any stats-related rules for v2 tables. Not all rules will be specific to reads. One option is to rename the current batch into something more generic but it would require changing quite some places. That's why it seems better to introduce a new batch and use it for all rewrites. The name is generic so that we don't limit ourselves to v2 data sources only.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

The change is trivial and SPARK-23889 will depend on it.

Anton Okolnychyi 478fb7f528 [SPARK-33608][SQL] Handle DELETE/UPDATE/MERGE in PullupCorrelatedPredicates
### What changes were proposed in this pull request?

This PR adds logic to handle DELETE/UPDATE/MERGE plans in `PullupCorrelatedPredicates`.
### Why are the changes needed?

Right now, `PullupCorrelatedPredicates` applies only to filters and unary nodes. As a result, correlated predicates in DELETE/UPDATE/MERGE are not rewritten.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

The PR adds 3 new test cases.

Prakhar Jain cf4ad212b1 [SPARK-33503][SQL] Refactor SortOrder class to allow multiple childrens
### What changes were proposed in this pull request?
This is a followup of #30302 . As part of this PR, sameOrderExpressions set is made part of children of SortOrder node - so that they don't need any special handling as done in #30302 .

### Why are the changes needed?
sameOrderExpressions should get same treatment as child. So making them part of children helps in transforming them easily.

### Does this PR introduce _any_ user-facing change?
No

gengjiaan 9273d4250d [SPARK-33045][SQL][FOLLOWUP] Support built-in function like_any and fix StackOverflowError issue
### What changes were proposed in this pull request?
Spark already support `LIKE ANY` syntax, but it will throw `StackOverflowError` if there are many elements(more than 14378 elements). We should implement built-in function for LIKE ANY to fix this issue.

Why the stack overflow can happen in the current approach ?
The current approach uses reduceLeft to connect each `Like(e, p)`, this will lead the the call depth of the thread is too large, causing `StackOverflowError` problems.

Why the fix in this PR can avoid the error?
This PR support built-in function for `LIKE ANY` and avoid this issue.

### Why are the changes needed?
1.Fix the `StackOverflowError` issue.
2.Support built-in function `like_any`.

### Does this PR introduce _any_ user-facing change?
'No'.

### How was this patch tested?
Jenkins test.

Closes #30465 from beliefer/SPARK-33045-like_any-bak.

Gabor Somogyi e5bb2937f6 [SPARK-32032][SS] Avoid infinite wait in driver because of KafkaConsumer.poll(long) API
### What changes were proposed in this pull request?
Deprecated `KafkaConsumer.poll(long)` API calls may cause infinite wait in the driver. In this PR I've added a new `AdminClient` based offset fetching which is turned off by default. There is a new flag named `spark.sql.streaming.kafka.useDeprecatedOffsetFetching` (default: `true`) which can be set to `false` to reach the newly added functionality. The Structured Streaming migration guide contains more information what migration consideration must be done. Please see the following [doc](https://docs.google.com/document/d/1gAh0pKgZUgyqO2Re3sAy-fdYpe_SxpJ6DkeXE8R1P7E/edit?usp=sharing) for further details.

The PR contains the following changes:
* Added `AdminClient` based offset fetching
* GroupId prefix feature removed from driver but only in `AdminClient` based approach (`AdminClient` doesn't need any GroupId)
* GroupId override feature removed from driver but only in `AdminClient` based approach  (`AdminClient` doesn't need any GroupId)
* Additional unit tests
* Code comment changes
* Minor bugfixes here and there
* Removed Kafka auto topic creation feature but only in `AdminClient` based approach (please see doc for rationale). In short, it's super hidden, not sure anybody ever used in production + error prone.
* Added documentation to `ss-migration-guide` and `structured-streaming-kafka-integration`

### Why are the changes needed?
Driver may hang forever.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
Existing + additional unit tests.
Cluster test with simple Kafka topic to another topic query.
Documentation:
```
cd docs/
SKIP_API=1 jekyll build
```
Manual webpage check.

Max Gekk 6fd148fea8 [SPARK-33569][SQL] Remove getting partitions by an identifier prefix
### What changes were proposed in this pull request?
1. Remove the method `listPartitionIdentifiers()` from the `SupportsPartitionManagement` interface. The method lists partitions by ident prefix.
2. Rename `listPartitionByNames()` to `listPartitionIdentifiers()`.
3. Re-implement the default method `partitionExists()` using new method.

### Why are the changes needed?
Getting partitions by ident prefix only is not used, and it can be removed to improve code maintenance. Also this makes the `SupportsPartitionManagement` interface cleaner.

### Does this PR introduce _any_ user-facing change?
Should not.

### How was this patch tested?
By running the affected test suites:
```
$ build/sbt "test:testOnly org.apache.spark.sql.connector.catalog.*"
