Kousuke Saruta 8e92ef825a [SPARK-35749][SPARK-35773][SQL] Parse unit list interval literals as tightest year-month/day-time interval types
### What changes were proposed in this pull request?

This PR allow the parser to parse unit list interval literals like `'3' day '10' hours '3' seconds` or `'8' years '3' months` as `YearMonthIntervalType` or `DayTimeIntervalType`.

### Why are the changes needed?

For ANSI compliance.

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

Yes. I noted the following things in the `sql-migration-guide.md`.

* Unit list interval literals are parsed as `YearMonthIntervaType` or `DayTimeIntervalType` instead of `CalendarIntervalType`.
* `WEEK`, `MILLISECONS`, `MICROSECOND` and `NANOSECOND` are not valid units for unit list interval literals.
* Units of year-month and day-time cannot be mixed like `1 YEAR 2 MINUTES`.

### How was this patch tested?

New tests and modified tests.

Closes #32949 from sarutak/day-time-multi-units.

Gengliang Wang 01ddaf3918 [SPARK-36119][SQL] Add new SQL function to_timestamp_ltz
### What changes were proposed in this pull request?

Add new SQL function `to_timestamp_ltz`
syntax:
```
to_timestamp_ltz(timestamp_str_column[, fmt])
to_timestamp_ltz(timestamp_column)
to_timestamp_ltz(date_column)
```

### Why are the changes needed?

As the result of to_timestamp become consistent with the SQL configuration spark.sql.timestmapType and there is already a SQL function to_timestmap_ntz, we need new function to_timestamp_ltz to construct timestamp with local time zone values.

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

Yes, a new function for constructing timestamp with local time zone values

### How was this patch tested?

Unit test

allisonwang-db 4f760f2b1f [SPARK-35551][SQL] Handle the COUNT bug for lateral subqueries
### What changes were proposed in this pull request?
This PR modifies `DecorrelateInnerQuery` to handle the COUNT bug for lateral subqueries. Similar to SPARK-15370, rewriting lateral subqueries as joins can change the semantics of the subquery and lead to incorrect answers.

However we can't reuse the existing code to handle the count bug for correlated scalar subqueries because it assumes the subquery to have a specific shape (either with Filter + Aggregate or Aggregate as the root node). Instead, this PR proposes a more generic way to handle the COUNT bug. If an Aggregate is subject to the COUNT bug, we insert a left outer domain join between the outer query and the aggregate with a `alwaysTrue` marker and rewrite the final result conditioning on the marker. For example:

```sql
-- t1: [(0, 1), (1, 2)]
-- t2: [(0, 2), (0, 3)]
select * from t1 left outer join lateral (select count(*) from t2 where t2.c1 = t1.c1)
```

Without count bug handling, the query plan is
```
Project [c1#44, c2#45, count(1)#53L]
+- Join LeftOuter, (c1#48 = c1#44)
   :- LocalRelation [c1#44, c2#45]
   +- Aggregate [c1#48], [count(1) AS count(1)#53L, c1#48]
      +- LocalRelation [c1#48]
```
and the answer is wrong:
```
+---+---+--------+
|c1 |c2 |count(1)|
+---+---+--------+
|0  |1  |2       |
|1  |2  |null    |
+---+---+--------+
```

With the count bug handling:
```
Project [c1#1, c2#2, count(1)#10L]
+- Join LeftOuter, (c1#34 <=> c1#1)
   :- LocalRelation [c1#1, c2#2]
   +- Project [if (isnull(alwaysTrue#32)) 0 else count(1)#33L AS count(1)#10L, c1#34]
      +- Join LeftOuter, (c1#5 = c1#34)
         :- Aggregate [c1#1], [c1#1 AS c1#34]
         :  +- LocalRelation [c1#1]
         +- Aggregate [c1#5], [count(1) AS count(1)#33L, c1#5, true AS alwaysTrue#32]
            +- LocalRelation [c1#5]
```
and we have the correct answer:
```
+---+---+--------+
|c1 |c2 |count(1)|
+---+---+--------+
|0  |1  |2       |
|1  |2  |0       |
+---+---+--------+
```

### Why are the changes needed?
Fix a correctness bug with lateral join rewrite.

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

### How was this patch tested?
Added SQL query tests. The results are consistent with Postgres' results.

Gengliang Wang 92bf83ed0a [SPARK-36046][SQL] Support new functions make_timestamp_ntz and make_timestamp_ltz
### What changes were proposed in this pull request?

Support new functions make_timestamp_ntz and make_timestamp_ltz
Syntax:
* `make_timestamp_ntz(year, month, day, hour, min, sec)`: Create local date-time from year, month, day, hour, min, sec fields
* `make_timestamp_ltz(year, month, day, hour, min, sec[, timezone])`: Create current timestamp with local time zone from year, month, day, hour, min, sec and timezone fields

### Why are the changes needed?

As the result of `make_timestamp` become consistent with the SQL configuration `spark.sql.timestmapType`, we need these two new functions to construct timestamp literals. They align to the functions [`make_timestamp` and `make_timestamptz`](https://www.postgresql.org/docs/9.4/functions-datetime.html) in PostgreSQL

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

Yes, two new datetime functions: make_timestamp_ntz and make_timestamp_ltz.

Gengliang Wang 32720dd3e1 [SPARK-36072][SQL] TO_TIMESTAMP: return different results based on the default timestamp type
### What changes were proposed in this pull request?

The SQL function TO_TIMESTAMP should return different results based on the default timestamp type:
* when "spark.sql.timestampType" is TIMESTAMP_NTZ, return TimestampNTZType literal
* when "spark.sql.timestampType" is TIMESTAMP_LTZ, return TimestampType literal

itholic 2537fe8cba [SPARK-35929][PYTHON] Support to infer nested dict as a struct when creating a DataFrame
### What changes were proposed in this pull request?

Currently, inferring nested structs is always using `MapType`.

This behavior causes an issue because it infers the schema with a value type of the first field of the struct as below:

```python
data = [{"inside_struct": {"payment": 100.5, "name": "Lee"}}]
df = spark.createDataFrame(data)
df.show(truncate=False)
+--------------------------------+
|inside_struct                   |
+--------------------------------+
|{name -> null, payment -> 100.5}|
+--------------------------------+
```

The "name" became `null`, but it should've been `"Lee"`.

In this case, we need to be able to infer the schema with a `StructType` instead of a `MapType`.

Therefore, this PR proposes adding an new configuration `spark.sql.pyspark.inferNestedDictAsStruct.enabled` to handle which type is used for inferring nested structs.
- When `spark.sql.pyspark.inferNestedDictAsStruct.enabled` is `false` (by default), inferring nested structs by `MapType`
- When `spark.sql.pyspark.inferNestedDictAsStruct.enabled` is `true`, inferring nested structs by `StructType`

### Why are the changes needed?

Because always inferring the nested structs by `MapType` doesn't work properly for some cases.

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

New configuration `spark.sql.pyspark.inferNestedDictAsStruct.enabled` is added.

### How was this patch tested?

Added an unit test

allisonwang-db ca348e50a4 [SPARK-36028][SQL] Allow Project to host outer references in scalar subqueries
### What changes were proposed in this pull request?
This PR allows the `Project` node to host outer references in scalar subqueries when `decorrelateInnerQuery` is enabled. It is already supported by the new decorrelation framework and the `RewriteCorrelatedScalarSubquery` rule.

Note currently by default all correlated subqueries will be decorrelated, which is not necessarily the most optimal approach. Consider `SELECT (SELECT c1) FROM t`. This should be optimized as `SELECT c1 FROM t` instead of rewriting it as a left outer join. This will be done in a separate PR to optimize correlated scalar/lateral subqueries with OneRowRelation.

### Why are the changes needed?
To allow more types of correlated scalar subqueries.

### Does this PR introduce _any_ user-facing change?
Yes. This PR allows outer query column references in the SELECT cluase of a correlated scalar subquery. For example:
```sql
SELECT (SELECT c1) FROM t;
```
Before this change:
```
org.apache.spark.sql.AnalysisException: Expressions referencing the outer query are not supported
outside of WHERE/HAVING clauses
```

After this change:
```
+------------------+
|scalarsubquery(c1)|
+------------------+
|0                 |
|1                 |
+------------------+
```

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

Linhong Liu 7566db6033 [SPARK-35984][SQL][TEST] Config to force applying shuffled hash join
### What changes were proposed in this pull request?
Add a config `spark.sql.join.forceApplyShuffledHashJoin` to force applying shuffled hash join
during the join selection.

### Why are the changes needed?
In the `SQLQueryTestSuite`, we want to cover 3 kinds of join (BHJ, SHJ, SMJ) in join.sql. But even
if the `spark.sql.join.preferSortMergeJoin` is set to `false`, shuffled hash join is still not guaranteed.
Thus, we need another config to force the selection.

### Does this PR introduce _any_ user-facing change?
No, only for testing

### How was this patch tested?
newly added tests
Verified all queries in join.sql will use `ShuffledHashJoin` when the config set to `true`

Kousuke Saruta def8bc5c96 [SPARK-35999][SQL] Make from_csv/to_csv to handle day-time intervals properly
### What changes were proposed in this pull request?

This PR fixes an issue that `from_csv/to_csv` doesn't handle day-time intervals properly.
`from_csv` throws exception if day-time interval types are given.
```
spark-sql> select from_csv("interval '1 2:3:4' day to second", "a interval day to second");
21/07/03 04:39:13 ERROR SparkSQLDriver: Failed in [select from_csv("interval '1 2:3:4' day to second", "a interval day to second")]
java.lang.Exception: Unsupported type: interval day to second

 at org.apache.spark.sql.catalyst.csv.UnivocityParser.$anonfun$valueConverters$1(UnivocityParser.scala:134)
```

Also, `to_csv` doesn't handle day-time interval types properly though any exception is thrown.
The result of `to_csv` for day-time interval types is not ANSI interval compliant form.

```
spark-sql> select to_csv(named_struct("a", interval '1 2:3:4' day to second));

```
The result above should be `INTERVAL '1 02:03:04' DAY TO SECOND`.

Kousuke Saruta c8ff613c3c [SPARK-35983][SQL] Allow from_json/to_json for map types where value types are day-time intervals
### What changes were proposed in this pull request?

This PR fixes two issues. One is that `to_json` doesn't support `map` types where value types are `day-time` interval types like:
```
spark-sql> select to_json(map('a', interval '1 2:3:4' day to second));
21/07/06 14:53:58 ERROR SparkSQLDriver: Failed in [select to_json(map('a', interval '1 2:3:4' day to second))]
java.lang.RuntimeException: Failed to convert value 93784000000 (class of class java.lang.Long) with the type of DayTimeIntervalType(0,3) to JSON.
```
The other issue is that even if the issue of `to_json` is resolved, `from_json` doesn't support to convert `day-time` interval string to JSON. So the result of following query will be `null`.
```
spark-sql> select from_json(to_json(map('a', interval '1 2:3:4' day to second)), 'a interval day to second');
{"a":null}
```

### Why are the changes needed?

There should be no reason why day-time intervals cannot used as map value types.
`CalendarIntervalTypes` can do it.

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

No.

### How was this patch tested?

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

This is a followup of https://github.com/apache/spark/pull/33113, to do some code cleanup:
1. `UnresolvedFieldPosition` doesn't need to include the field name. We can get it through "context" (`AlterTableAlterColumn.column.name`).
2. Run `ResolveAlterTableCommands` in the main resolution batch, so that the column/field resolution is also unified between v1 and v2 commands (same error message).
3. Fail immediately in `ResolveAlterTableCommands` if we can't resolve the field, instead of waiting until `CheckAnalysis`. We don't expect other rules to resolve fields in ALTER  TABLE commands, so failing immediately is simpler and we can remove duplicated code in `CheckAnalysis`.

Gengliang Wang 2fffec7de8 [SPARK-35979][SQL] Return different timestamp literals based on the default timestamp type
### What changes were proposed in this pull request?

For the timestamp literal, it should have the following behavior.
1. When `spark.sql.timestampType` is TIMESTAMP_NTZ: if there is no time zone part, return timestamp without time zone literal; otherwise, return timestamp with local time zone literal

2. When `spark.sql.timestampType` is TIMESTAMP_LTZ: return timestamp with local time zone literal

### Why are the changes needed?

When the default timestamp type is TIMESTAMP_NTZ, the result of type literal should return TIMESTAMP_NTZ when there is no time zone part in the string.

From setion 5.3 "literal" of ANSI SQL standard 2011:
```
27) The declared type of a <timestamp literal> that does not specify <time zone interval> is TIMESTAMP(P) WITHOUT TIME ZONE, where P is the number of digits in <seconds fraction>, if specified, and 0 (zero) otherwise. The declared type of a <timestamp literal> that specifies <time zone interval> is TIMESTAMP(P) WITH TIME ZONE, where P is the number of digits in <seconds fraction>, if specified, and 0 (zero) otherwise.
```
Since we don't have "timestamp with time zone", we use timestamp with local time zone instead.
### Does this PR introduce _any_ user-facing change?

No, the new timestmap type and the default timestamp configuration is not released yet.

Cheng Su 044dddf288 [SPARK-35794][SQL] Allow custom plugin for AQE cost evaluator
### What changes were proposed in this pull request?

Current AQE has cost evaluator to decide whether to use new plan after replanning. The current used evaluator is `SimpleCostEvaluator` to make decision based on number of shuffle in the query plan. This is not perfect cost evaluator, and different production environments might want to use different custom evaluators. E.g., sometimes we might want to still do skew join even though it might introduce extra shuffle (trade off resource for better latency), sometimes we might want to take sort into consideration for cost as well. Take our own setting as an example, we are using a custom remote shuffle service (Cosco), and the cost model is more complicated. So We want to make the cost evaluator to be pluggable, and developers can implement their own `CostEvaluator` subclass and plug in dynamically based on configuration.

The approach is to introduce a new config to allow define sub-class name of `CostEvaluator` - `spark.sql.adaptive.customCostEvaluatorClass`. And add `CostEvaluator.instantiate` to instantiate the cost evaluator class in `AdaptiveSparkPlanExec.costEvaluator`.

### Why are the changes needed?

Make AQE cost evaluation more flexible.

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

No but an internal config is introduced - `spark.sql.adaptive.customCostEvaluatorClass` to allow custom implementation of `CostEvaluator`.

### How was this patch tested?

Added unit test in `AdaptiveQueryExecSuite.scala`.

Wenchen Fan 0c9c8ff569 [SPARK-35968][SQL] Make sure partitions are not too small in AQE partition coalescing
### What changes were proposed in this pull request?

By default, AQE will set `COALESCE_PARTITIONS_MIN_PARTITION_NUM` to the spark default parallelism, which is usually quite big. This is to keep the parallelism on par with non-AQE, to avoid perf regressions.

However, this usually leads to many small/empty partitions, and hurts performance (although not worse than non-AQE). Users usually blindly set `COALESCE_PARTITIONS_MIN_PARTITION_NUM` to 1, which makes this config quite useless.

This PR adds a new config to set the min partition size, to avoid too small partitions after coalescing. By default, Spark will not respect the target size, and only respect this min partition size, to maximize the parallelism and avoid perf regression in AQE. This PR also adds a bool config to respect the target size when coalescing partitions, and it's recommended to set it to get better overall performance. This PR also deprecates the `COALESCE_PARTITIONS_MIN_PARTITION_NUM` config.

### Why are the changes needed?

AQE is default on now, we should make the perf better in the default case.

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

yes, a new config.

### How was this patch tested?

Rahul Mahadev 47485a3c2d [SPARK-35897][SS] Support user defined initial state with flatMapGroupsWithState in Structured Streaming
### What changes were proposed in this pull request?
This PR aims to add support for specifying a user defined initial state for arbitrary structured streaming stateful processing using [flat]MapGroupsWithState operator.

### Why are the changes needed?
Users can load previous state of their stateful processing as an initial state instead of redoing the entire processing once again.

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

Yes this PR introduces new API
```
  def mapGroupsWithState[S: Encoder, U: Encoder](
      timeoutConf: GroupStateTimeout,
      initialState: KeyValueGroupedDataset[K, S])(
      func: (K, Iterator[V], GroupState[S]) => U): Dataset[U]

  def flatMapGroupsWithState[S: Encoder, U: Encoder](
      outputMode: OutputMode,
      timeoutConf: GroupStateTimeout,
      initialState: KeyValueGroupedDataset[K, S])(
      func: (K, Iterator[V], GroupState[S]) => Iterator[U])

```

### How was this patch tested?

Anton Okolnychyi fceabe2372 [SPARK-35779][SQL] Dynamic filtering for Data Source V2
### What changes were proposed in this pull request?

This PR implemented the proposal per [design doc](https://docs.google.com/document/d/1RfFn2e9o_1uHJ8jFGsSakp-BZMizX1uRrJSybMe2a6M) for SPARK-35779.

### Why are the changes needed?

Spark supports dynamic partition filtering that enables reusing parts of the query to skip unnecessary partitions in the larger table during joins. This optimization has proven to be beneficial for star-schema queries which are common in the industry. Unfortunately, dynamic pruning is currently limited to partition pruning during joins and is only supported for built-in v1 sources. As more and more Spark users migrate to Data Source V2, it is important to generalize dynamic filtering and expose it to all v2 connectors.

Please, see the design doc for more information on this effort.

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

Yes, this PR adds a new optional mix-in interface for `Scan` in Data Source V2.

### How was this patch tested?

This PR comes with tests.

Gengliang Wang a643076d4e [SPARK-35975][SQL] New configuration spark.sql.timestampType for the default timestamp type
### What changes were proposed in this pull request?

Add a new configuration `spark.sql.timestampType`, which configures the default timestamp type of Spark SQL, including SQL DDL and Cast clause. Setting the configuration as `TIMESTAMP_NTZ` will use `TIMESTAMP WITHOUT TIME ZONE` as the default type while putting it as `TIMESTAMP_LTZ` will use `TIMESTAMP WITH LOCAL TIME ZONE`.

The default value of the new configuration is TIMESTAMP_LTZ, which is consistent with previous Spark releases.

### Why are the changes needed?

A new configuration for switching the default timestamp type as timestamp without time zone.

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

No, it's a new feature.

### How was this patch tested?

SaurabhChawla ca1217667c [SPARK-35756][SQL] unionByName supports struct having same col names but different sequence
### What changes were proposed in this pull request?

unionByName does not supports struct having same col names but different sequence
```
val df1 = Seq((1, Struct1(1, 2))).toDF("a", "b")
val df2 = Seq((1, Struct2(1, 2))).toDF("a", "b")
val unionDF = df1.unionByName(df2)
```
it gives the exception

`org.apache.spark.sql.AnalysisException: Union can only be performed on tables with the compatible column types. struct<c2:int,c1:int> <> struct<c1:int,c2:int> at the second column of the second table; 'Union false, false :- LocalRelation [_1#38, _2#39] +- LocalRelation _1#45, _2#46`

In this case the col names are same so this unionByName should have the support to check within in the Struct if col names are same it should not throw this exception and works.

after fix we are getting the result

```
val unionDF = df1.unionByName(df2)
scala>  unionDF.show
+---+------+
|  a|     b|
+---+------+
|  1|{1, 2}|
|  1|{2, 1}|
+---+------+

```

### Why are the changes needed?
As per unionByName functionality based on name, does the union. In the case of struct this scenario was missing where all the columns  names are same but sequence is different,  so added this functionality.

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

Linhong Liu 3c683434fa [SPARK-35686][SQL] Not allow using auto-generated alias when creating view
### What changes were proposed in this pull request?
As described in  #32831, Spark has compatible issues when querying a view created by an
older version. The root cause is that Spark changed the auto-generated alias name. To avoid
this in the future, we could ask the user to specify explicit column names when creating
a view.

### Why are the changes needed?

Linhong Liu 0c34b96541 [SPARK-35685][SQL] Prompt recreating the view when there is an incompatible schema issue
### What changes were proposed in this pull request?
If the user creates a view in 2.4 and reads it in 3.1/3.2, there will be an incompatible schema issue.
So this PR adds a view ddl in the error message to prompt the user recreating the view to fix the
incompatible issue.
For example:
```sql
-- create view in 2.4
CREATE TABLE IF NOT EXISTS t USING parquet AS SELECT '1' as a, '20210420' as b"
CREATE OR REPLACE VIEW v AS SELECT CAST(t.a AS INT), to_date(t.b, 'yyyyMMdd') FROM t
-- select view in master
SELECT * FROM v
```
Then we will get below error:
```
cannot resolve '`to_date(spark_catalog.default.t.b, 'yyyyMMdd')`' given input columns: [a, to_date(b, yyyyMMdd)];
```

### Why are the changes needed?

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

Rename TimestampWithoutTZType to TimestampNTZType

### Why are the changes needed?

The time name of `TimestampWithoutTZType` is verbose. Rename it as `TimestampNTZType` so that
1. it is easier to read and type.
2. As we have the function to_timestamp_ntz, this makes the names consistent.
3. We will introduce a new SQL configuration `spark.sql.timestampType` for the default timestamp type. The configuration values can be "TIMESTMAP_NTZ" or "TIMESTMAP_LTZ" for simplicity.

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

No, the new timestamp type is not released yet.

ulysses-you d46c1e38ec [SPARK-35725][SQL] Support optimize skewed partitions in RebalancePartitions
### What changes were proposed in this pull request?

* Add a new rule `ExpandShufflePartitions` in AQE `queryStageOptimizerRules`
* Add a new config `spark.sql.adaptive.optimizeSkewsInRebalancePartitions.enabled` to decide if should enable the new rule

The new rule `OptimizeSkewInRebalancePartitions` only handle two shuffle origin `REBALANCE_PARTITIONS_BY_NONE` and `REBALANCE_PARTITIONS_BY_COL` for data skew issue. And re-use the exists config `ADVISORY_PARTITION_SIZE_IN_BYTES` to decide what partition size should be.

### Why are the changes needed?

Currently, we don't support expand partition dynamically in AQE which is not friendly for some data skew job.

Let's say if we have a simple query:
```
SELECT /*+ REBALANCE(col) */ * FROM table
```

The column of `col` is skewed, then some shuffle partitions would handle too much data than others.

If we haven't inroduced extra shuffle, we can optimize this case by expanding partitions in AQE.

Yes, a new config

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

Add a new ANSI type coercion rule: when getting a date field from a Timestamp column, cast the column as Date type.

This is Spark's current hack to make the implementation simple. In the default type coercion rules, the implicit cast rule does the work. However, The ANSI implicit cast rule doesn't allow converting Timestamp type as Date type, so we need to have this additional rule to make sure the date field extraction from Timestamp columns works.

1. simplify the pattern match
2. In the default type coercion rules, when implicit casting a type to a TypeCollection type, Spark chooses the first convertible data type as the result. If we are going to make the default timestamp type configurable, having AnyTimestampType is better

This issue happens when aliases are eliminated by `AliasHelper.replaceAliasButKeepName` or `AliasHelper.trimNonTopLevelAliases` called via analyzer/optimizer

I investigated functions which can be affected this issue but I found only `arrays_zip` so far.

To fix this issue, this PR changes the definition of `ArraysZip` to retain field names to avoid being re-written by analyzer/optimizer.

### Why are the changes needed?

This is apparently a bug.

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

No. After this change, the field names are no longer re-written but it should be expected behavior for users.

### How was this patch tested?

New tests.

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

This PR proposes to migrate the following `ALTER TABLE ... CHANGE COLUMN` command to use `UnresolvedTable` as a `child` 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).

### Why are the changes needed?

This is a part of effort to make the relation lookup behavior consistent: [SPARK-29900](https://issues.apache.org/jira/browse/SPARK-29900).

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

Adam Binford 14b1836313 [SPARK-35290][SQL] Append new nested struct fields rather than sort for unionByName with null filling
### What changes were proposed in this pull request?

This PR changes the unionByName with null filling logic to append new nested struct fields from the right side of the union to the schema versus sorting fields alphabetically. It removes the need to use UpdateField expressions, and just directly projects new nested structs from each side of the union with the correct schema. This changes the union'd schema from being alphabetically sorted previously to now "left dominant", where the fields from the left side of the union are included and then the missing ones from the right are added in the same order found originally.

### Why are the changes needed?

Certain nested structs would cause unionByName with null filling to error out due to part of the logic for rewriting the expression tree to sort the structs.

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

Yes, nested struct fields will be in a different order after unionByName with null filling than before, though shouldn't cause much effective difference.

### How was this patch tested?

Updated existing tests based on the new StructField ordering and added a new test for the case that was broken originally.

ulysses-you 1295e8876c [SPARK-35786][SQL] Add a new operator to distingush if AQE can optimize safely
### What changes were proposed in this pull request?

* Add a new repartition operator `RebalanceRepartition`.
* Support a new hint `REBALANCE`

After this patch, user can run this query:
```sql
SELECT /*+ REBALANCE(c) */ * FROM t
```

### Why are the changes needed?

Add a new hint to distingush if we can optimize it safely.

This new hint can let AQE optimize with `CustomShuffleReaderExec` safely. Currently, AQE can only coalesce shuffle partitions but can not expand shuffle partitions due to the semantics of output partitioning.
Let's say we have a query:
```sql
SELECT /*+ REPARTITION(col) */ * FROM t
```
AQE can not expand the shuffle partitions even if `col` is skewed because expanding shuffle partitions will break the hashed output paritioning of `RepartitionByExpression`. But if the query is use`REPARTITION_BY_AQE`, AQE can optimize it without considering the semantics of output partitioning.

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

Yes, a new hint.

### How was this patch tested?

Add test.

dgd-contributor 5b9c5c126f [SPARK-35841][SQL] Casting string to decimal type doesn't work if the…
… sum of the digits is greater than 38
### What changes were proposed in this pull request?
Since Spark 3.1.1, NULL is returned when casting a string with many decimal places to a decimal type. If the sum of the digits before and after the decimal point is less than 39, a value is returned. From 39 digits, however, NULL is returned.
This worked until Spark 3.0.X.

Code to reproduce:

A string with 2 decimal places in front of the decimal point and 37 decimal places after the decimal point returns null

```
val data = Seq(
      "28.9259999999999983799625624669715762138",
      "28.925999999999998379962562466971576213",
      "2.9259999999999983799625624669715762138"
      )
val df = data.toDF("num")
df.withColumn("numConverted", col("num").cast("decimal(38, 5)")).show()
```

before this pull request, the result is
+----------------------+---------------+
|                 num          |numConverted|
+----------------------+---------------+
|28.92599999999999...|                  null|

|2.925999999999998...|           2.92600|
+----------------------+---------------+

the correct result should be

|                 num          |numConverted|

tanel.kiis@gmail.com b3a2cebc2b [SPARK-34807][SQL] Transpose Window nodes with Project between them
### What changes were proposed in this pull request?

Extend the `TransposeWindow` rule to transpose `Window` nodes, that have `Project` between them.

### Why are the changes needed?

The analyzer will turn a `dataset.withColumn("colName", expressionWithWindowFunction)` method call to a `Project - Window - Project` chain in the logical plan. When this method is called multiple times in a row, then the projects can block the `Window` nodes from being transposed by the current `TransposeWindow` rule.

TPCDS q47 and q57 are also improved by this.

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

No

### How was this patch tested?

Gengliang Wang 6f51e37eb5 [SPARK-35857][SQL] The ANSI flag of Cast should be kept after being copied
### What changes were proposed in this pull request?

Make the ANSI flag part of expression `Cast`'s  parameter list, instead of fetching it from the sessional SQLConf.

### Why are the changes needed?

For Views, it is important to show consistent results even the ANSI configuration is different in the running session. This is why many expressions like 'Add'/'Divide' making the ANSI flag part of its case class parameter list.

We should make it consistent for the expression `Cast`

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

Yes, the `Cast` inside a View always behaves the same, independent of the ANSI model SQL configuration in the current session.

### How was this patch tested?

Angerszhuuuu 758b423a31 [SPARK-35860][SQL] Support UpCast between different field of YearMonthIntervalType/DayTimeIntervalType
### What changes were proposed in this pull request?
Support UpCast between different field of YearMonthIntervalType/DayTimeIntervalType

### Why are the changes needed?
Since in our encoder we handle Period/Duration as default  YearMonthIntervalType/DayTimeIntervalType, when we use udf to handle this type, it will upcast all type of YearMonthIntervalType/DayTimeIntervalType to default YearMonthIntervalType/DayTimeIntervalType, so we need to support this.

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

### How was this patch tested?
Added Ut

Peter Toth 79e3d0d98f [SPARK-35855][SQL] Unify reuse map data structures in non-AQE and AQE rules
### What changes were proposed in this pull request?
This PR unifies reuse map data structures in non-AQE and AQE rules to a simple `Map[<canonicalized plan>, <plan>]` based on the discussion here: https://github.com/apache/spark/pull/28885#discussion_r655073897

### Why are the changes needed?
The proposed `Map[<canonicalized plan>, <plan>]` is simpler than the currently used `Map[<schema>, ArrayBuffer[<plan>]]` in `ReuseMap`/`ReuseExchangeAndSubquery` (non-AQE) and consistent with the `ReuseAdaptiveSubquery` (AQE) subquery reuse rule.

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

### How was this patch tested?
Existing UTs.

Wenchen Fan 20edfdd39a [SPARK-35845][SQL] OuterReference resolution should reject ambiguous column names
### What changes were proposed in this pull request?

The current OuterReference resolution is a bit weird: when the outer plan has more than one child, it resolves OuterReference from the output of each child, one by one, left to right.

This is incorrect in the case of join, as the column name can be ambiguous if both left and right sides output this column.

This PR fixes this bug by resolving OuterReference with `outerPlan.resolveChildren`, instead of something like `outerPlan.children.foreach(_.resolve(...))`

### Why are the changes needed?

bug fix

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

The problem only occurs in join, and join condition doesn't support correlated subquery yet. So this PR only improves the error message. Before this PR, people see
```
java.lang.UnsupportedOperationException
Cannot generate code for expression: outer(t1a#291)
```

### How was this patch tested?

a new test

Closes #33004 from cloud-fan/outer-ref.

Kousuke Saruta 4416b4b8ba [SPARK-35734][SQL][FOLLOWUP] IntervalUtils.toDayTimeIntervalString should consider the case a day-time type is casted as another day-time type
### What changes were proposed in this pull request?

This PR fixes an issue that `IntervalUtils.toDayTimeIntervalString` doesn't consider the case that a day-time interval type is casted as another day-time interval type.
if data of `interval day to second` is casted as `interval hour to second`, the value of the day is multiplied by 24 and added to the value of hour. For example, `INTERVAL '1 2' DAY TO HOUR` will be `INTERVAL '26' HOUR` if it's casted.
If this behavior is intended, it should be stringified as `INTERVAL '26' HOUR` but currently, it will be `INTERVAL '2' HOUR`

### Why are the changes needed?

t's a bug if the behavior of cast is intended.

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

No, because this feature is not released yet.

### How was this patch tested?

Modified the tests added in SPARK-35734 (#32891)

Gengliang Wang 960a7e5fce [SPARK-35856][SQL][TESTS] Move new interval type test cases from CastSuite to CastBaseSuite
### What changes were proposed in this pull request?

There are a few test cases that are supposed to be in CastSuiteBase instead of CastSuite:

- SPARK-35112: Cast string to day-time interval
- SPARK-35111: Cast string to year-month interval
- SPARK-35820: Support cast DayTimeIntervalType in different fields
- SPARK-35819: Support cast YearMonthIntervalType in different fields

This PR is to move them to CastSuiteBase. Also, it adds comments for the scope of CastSuiteBase/CastSuite/AnsiCastSuiteBase.
### Why are the changes needed?

Increase test coverage so that we can test the casting under ANSI mode.

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

No

Gengliang Wang ce53b7199d [SPARK-35854][SQL] Improve the error message of to_timestamp_ntz with invalid format pattern
### What changes were proposed in this pull request?

When SQL function `to_timestamp_ntz` has invalid format pattern input, throw a runtime exception with hints for the valid patterns, instead of throwing an upgrade exception with suggestions to use legacy formatters.

### Why are the changes needed?

As discussed in https://github.com/apache/spark/pull/32995/files#r655148980, there is an error message saying
"You may get a different result due to the upgrading of Spark 3.0: Fail to recognize 'yyyy-MM-dd GGGGG' pattern in the DateTimeFormatter. 1) You can set spark.sql.legacy.timeParserPolicy to LEGACY to restore the behavior before Spark 3.0"

This is not true for function to_timestamp_ntz, which only uses the Iso8601TimestampFormatter and added since Spark 3.2. We should improve it.

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

No, the new SQL function is not released yet.

### How was this patch tested?
