Jungtaek Lim 67eddf2ffc [SPARK-35894][BUILD] Introduce new style enforce to not import scala.collection.Seq/IndexedSeq
### What changes were proposed in this pull request?

This PR proposes to add a new scalastyle rule to enforce not importing `scala.collection.Seq` and `scala.collection.IndexedSeq` which conflicts with `scala.Seq` and `scala.IndexedSeq`.

The problem occurs as Scala 2.13 changed the alias of `scala.Seq` and `scala.IndexedSeq`. Before Scala 2.13, they were `scala.collection.Seq` and `scala.collection.IndexedSeq`. After Scala 2.13, they become `scala.collection.immutable.Seq` and `scala.collection.immutable.IndexedSeq`.

Please refer below doc for more details.
https://docs.scala-lang.org/overviews/core/collections-migration-213.html

### Why are the changes needed?

We have seen Seq/IndexedSeq issues on cross-compilation of Scala 2.12 / 2.13. While I'm not sure this can prevent all cases, this will prevent the simple case of breaking cross compilation.

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

No change on end user. Contributors will be restricted but shouldn't block them doing the right thing.

### How was this patch tested?

Ran scalastyle against current master (before #33084)

Terry Kim f1ad34558c [SPARK-35883][SQL] Migrate ALTER TABLE RENAME COLUMN command to use UnresolvedTable to resolve the identifier
### What changes were proposed in this pull request?

This PR proposes to migrate the following `ALTER TABLE ... RENAME 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?

After this PR, the above `ALTER TABLE ... RENAME COLUMN` commands will have a consistent resolution behavior.

### How was this patch tested?

Updated existing tests.

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|
+----------------------+---------------+
|28.92599999999999...|         28.92600|

Vinod KC 4dabba8f76 [SPARK-35747][CORE] Avoid printing full Exception stack trace, if Hbase/Kafka/Hive services are not running in a secure cluster
### What changes were proposed in this pull request?
In a secure Yarn cluster, even though HBase or Kafka, or Hive services are not used in the user application, yarn client unnecessarily trying to generate  Delegations token from these services. This will add additional delays while submitting spark application in a yarn cluster

 Also during HBase delegation token generation step in the application submit stage,  HBaseDelegationTokenProvider prints a full Exception Stack trace and it causes a noisy warning.
 Apart from printing exception stack trace, Application submission taking more time as it retries connection to HBase master multiple times before it gives up. So, if HBase is not used in the user Applications, it is better to suggest User disable HBase Delegation Token generation.

 This PR aims to avoid printing full Exception Stack by just printing just Exception name and also add a suggestion message to disable `Delegation Token generation` if service is not used in the Spark Application.

 eg: `If HBase is not used, set spark.security.credentials.hbase.enabled to false`

### Why are the changes needed?

To avoid printing full Exception stack trace in WARN log

### 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.

Jungtaek Lim (HeartSaVioR) 476197791b [SPARK-34889][SS] Introduce MergingSessionsIterator merging elements directly which belong to the same session
Introduction: this PR is a part of SPARK-10816 (`EventTime based sessionization (session window)`). Please refer #31937 to see the overall view of the code change. (Note that code diff could be diverged a bit.)

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

This PR introduces MergingSessionsIterator, which enables to merge elements belong to the same session directly.

MergingSessionsIterator is a variant of SortAggregateIterator which merges the session windows based on the fact input rows are sorted by "group keys + the start time of session window". When merging windows, MergingSessionsIterator also applies aggregations on merged window, which eliminates the necessity on buffering inputs (which requires copying rows) and update the session spec for each input.

MergingSessionsIterator is quite performant compared to UpdatingSessionsIterator brought by SPARK-34888. Note that MergingSessionsIterator can only apply to the cases aggregation can be applied altogether, so there're still rooms for UpdatingSessionIterator to be used.

This issue also introduces MergingSessionsExec which is the physical node on leveraging MergingSessionsIterator to sort the input rows and aggregate rows according to the session windows.

### Why are the changes needed?

This part is a one of required on implementing SPARK-10816.

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

No.

### How was this patch tested?

New test suite added.

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

Move all the bookkeeping states while scanning a Parquet column chunk into a single class `ParquetReadState`.

### Why are the changes needed?

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

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?

### 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

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.

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

We introduced `SparkSession.withActive` a while ago, and we use it when we need to run some code with a certain SparkSession as the active session.

Somehow we missed `SparkPlan.makeCopy`, which sets active session directly. This PR proposes to call `SparkSession.withActive` there.

### Why are the changes needed?

make sure we don't change the active session unexpectedly.

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

No. `makeCopy` is an internal function and I can't find a real case that this can change the active session. Mostly in an upper level, there is already a `SparkSession.withActive`, like `QueryExecution.executePhase`

Wenchen Fan a2c1a55b1f [SPARK-35700][SQL][FOLLOWUP] Read schema from ORC files should strip CHAR/VARCHAR types
### What changes were proposed in this pull request?

This is a followup of https://github.com/apache/spark/pull/33001 , to provide a more direct fix.

The regression in 3.1 was caused by the fact that we changed the parser and allow the parser to return CHAR/VARCHAR type. We should have replaced CHAR/VARCHAR with STRING before the data type flows into the query engine, however, `OrcUtils` is missed.

When reading ORC files, at the task side we will read the real schema from ORC file metadata, then apply filter pushdown. For some reason, the implementation turns ORC schema to Spark schema before filter pushdown, and this step does not strip CHAR/VARCHAR. Note, for Parquet we use the Parquet schema directly in filter pushdown, and do not this have problem.

This PR proposes to replace the CHAR/VARCHAR with STRING when turning ORC schema to Spark schema.

### Why are the changes needed?

Li Zhang dfd7b026dc [SPARK-35800][SS] Improving GroupState testability by introducing TestGroupState
### What changes were proposed in this pull request?
Proposed changes in this pull request:

1. Introducing the `TestGroupState` interface which is inherited from `GroupState` so that testing related getters can be exposed in a controlled manner
2. Changing `GroupStateImpl` to inherit from `TestGroupState` interface, instead of directly from `GroupState`
3. Implementing `TestGroupState` object with `create()` method to forward inputs to the private `GroupStateImpl` constructor
4. User input validations have been added into `GroupStateImpl`'s `createForStreaming()` method to prevent users from creating invalid GroupState objects.
5. Replacing existing `GroupStateImpl` usages in sql pkg internal unit tests with the newly added `TestGroupState` to give user best practice about `TestGroupState` usage.

With the changes in this PR, the class hierarchy is changed from `GroupStateImpl` -> `GroupState` to `GroupStateImpl` -> `TestGroupState` -> `GroupState` (-> means inherits from)

### Why are the changes needed?
The internal `GroupStateImpl` implementation for the `GroupState` interface has no public constructors accessible outside of the sql pkg. However, the user-provided state transition function for `[map|flatMap]GroupsWithState` requires a `GroupState` object as the prevState input.

Currently, users are calling the Structured Streaming engine in their unit tests in order to instantiate such `GroupState` instances, which makes UTs cumbersome.

The proposed `TestGroupState` interface is to give users controlled access to the `GroupStateImpl` internal implementation to largely improve testability of Structured Streaming state transition functions.

**Usage Example**
```
import org.apache.spark.sql.streaming.TestGroupState

test(“Structured Streaming state update function”) {
  var prevState = TestGroupState.create[UserStatus](
    optionalState = Optional.empty[UserStatus],
    timeoutConf = EventTimeTimeout,
    batchProcessingTimeMs = 1L,
    eventTimeWatermarkMs = Optional.of(1L),
    hasTimedOut = false)

  val userId: String = ...
  val actions: Iterator[UserAction] = ...

  assert(!prevState.hasUpdated)

  updateState(userId, actions, prevState)

  assert(prevState.hasUpdated)
}
```

### Does this PR introduce _any_ user-facing change?
Yes, the `TestGroupState` interface and its corresponding `create()` factory function in its companion object are introduced in this pull request for users to use in unit tests.

### How was this patch tested?
- New unit tests are added
- Existing GroupState unit tests are updated

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.

### What changes were proposed in this pull request?
#32513 added the case class `CommandResult` so as we can eagerly execute command locally. But we forgot to update
`isLocal` of `Dataset`.

### Why are the changes needed?
`Dataset.isLocal` should consider `CommandResult`.

### Does this PR introduce _any_ user-facing change?
Yes. If the SQL plan is `CommandResult`, `Dataset.isLocal` must return true.

### How was this patch tested?
No test.

Venki Korukanti d4d11cfbfb [SPARK-35799][SS] Fix the allUpdatesTimeMs metric measuring in FlatMapGroupsWithStateExec
### What changes were proposed in this pull request?

Fix how we measure the metric `allUpdatesTimeMs` in `FlatMapGroupsWithStateExec` similar to other streaming stateful operators.

### Why are the changes needed?

Metric `allUpdatesTimeMs` meant to capture the start to end walltime of the operator `FlatMapGroupsWithStateExec`, but currently it just [captures](79362c4efc/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/FlatMapGroupsWithStateExec.scala (L121)) the iterator creation time.

Fix it to measure similar to how other stateful operators measure. Example one [here](79362c4efc/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/statefulOperators.scala (L406)). This measurement is not perfect due to the nature of the lazy iterator and also includes the time the consumer operator spent in processing the current operator output, but it should give a good signal when comparing the metric in one microbatch to the metric in another microbatch.

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

No

### How was this patch tested?

Existing UTs for regression. Due to the nature of metric type (time), it is hard to write a UT, but have manually verified.

Gengliang Wang 2bdd9fe5e3 [SPARK-35839][SQL] New SQL function: to_timestamp_ntz
### What changes were proposed in this pull request?

Implement new SQL function: `to_timestamp_ntz`.
The syntax is similar to the built-in function `to_timestamp`:
```
to_timestamp_ntz ( <date_expr> )

to_timestamp_ntz ( <timestamp_expr> )

to_timestamp_ntz ( <string_expr> [ , <format> ] )
```

The naming is from snowflake: https://docs.snowflake.com/en/sql-reference/functions/to_timestamp.html

### Why are the changes needed?

Adds a new SQL function to create a literal/column of timestamp without time zone.
It's convenient for both end-users and developers.

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

Yes, a new SQL function `to_timestamp_ntz`.

### How was this patch tested?

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

Extend the `CollapseWindow` rule to collapse `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 collapsed by the current `CollapseWindow` rule.

Peter Toth 682e7f2033 [SPARK-29375][SPARK-28940][SPARK-32041][SQL] Whole plan exchange and subquery reuse
### What changes were proposed in this pull request?
This PR:
1. Fixes an issue in `ReuseExchange` rule that can result a `ReusedExchange` node pointing to an invalid exchange. This can happen due to the 2 separate traversals in `ReuseExchange` when the 2nd traversal modifies an exchange that has already been referenced (reused) in the 1st traversal.
   Consider the following query:
   ```
   WITH t AS (
     SELECT df1.id, df2.k
     FROM df1 JOIN df2 ON df1.k = df2.k
     WHERE df2.id < 2
   )
   SELECT * FROM t AS a JOIN t AS b ON a.id = b.id
   ```
   Before this PR the plan of the query was (note the `<== this reuse node points to a non-existing node` marker):
   ```
   == Physical Plan ==

2. Fixes an issue with separate consecutive `ReuseExchange` and `ReuseSubquery` rules that can result a `ReusedExchange` node pointing to an invalid exchange. This can happen due to the 2 separate rules when `ReuseSubquery` rule modifies an exchange that has already been referenced (reused) in `ReuseExchange` rule.
   Consider the following query:
   ```
   WITH t AS (
     SELECT df1.id, df2.k
     FROM df1 JOIN df2 ON df1.k = df2.k
     WHERE df2.id < 2
   ),
   t2 AS (
     SELECT * FROM t
     UNION
     SELECT * FROM t
   )
   SELECT * FROM t2 AS a JOIN t2 AS b ON a.id = b.id
   ```
   Before this PR the plan of the query was (note the `<== this reuse node points to a non-existing node` marker):

   (This example contains issue 1 as well.)

3. Improves the reuse of exchanges and subqueries by enabling reuse across the whole plan. This means that the new combined rule utilizes the reuse opportunities between parent and subqueries by traversing the whole plan. The traversal is started on the top level query only.

4. Due to the order of traversal this PR does while adding reuse nodes, the reuse nodes appear in parent queries if reuse is possible between different levels of queries (typical for DPP). This is not an issue from execution perspective, but this also means "forward references" in explain formatted output where parent queries come first. The changes I made to `ExplainUtils` are to handle these references properly.

This PR fixes the above 3 issues by unifying the separate rules into a `ReuseExchangeAndSubquery` rule that does a 1 pass, whole-plan, bottom-up traversal.

### Why are the changes needed?
Performance improvement.

### How was this patch tested?
- New UTs in `ReuseExchangeAndSubquerySuite` to cover 1. and 2.
- New UTs in `DynamicPartitionPruningSuite`, `SubquerySuite` and `ExchangeSuite` to cover 3.
- New `ReuseMapSuite` to test `ReuseMap`.
- Checked new golden files of `PlanStabilitySuite`s for invalid reuse references.
- TPCDS benchmarks.

Kousuke Saruta af20474c67 [SPARK-35827][SQL] Show proper error message when update column types to year-month/day-time interval
### What changes were proposed in this pull request?

This PR fixes error message shown when changing a column type to year-month/day-time interval type is attempted.

### Why are the changes needed?

It's for consistent behavior.
Updating column types to interval types are prohibited for V2 source tables.
So, if we attempt to update the type of a column to the conventional interval type, an error message like `Error in query: Cannot update <table> field <column> to interval type;`.

But, for year-month/day-time interval types, another error message like `Error in query: Cannot update <table> field <column>:<type> cannot be cast to interval year;`.

You can reproduce with the following procedure.
```
$ bin/spark-sql
spark-sql> SET spark.sql.catalog.mycatalog=<a catalog implementation class>;
spark-sql> CREATE TABLE mycatalog.t1(c1 int) USING <V2 datasource implementation class>;
spark-sql> ALTER TABLE mycatalog.t1 ALTER COLUMN c1 TYPE interval year to month;
```

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

No.

Modified an existing test.

Kousuke Saruta 4758dc78a2 [SPARK-35771][SQL][FOLLOWUP] IntervalUtils.toYearMonthIntervalString should consider the case year-month type is casted as month type
### What changes were proposed in this pull request?

This PR fixes an issue that `IntervalUtils.toYearMonthIntervalString` doesn't consider the case that year-month interval type is casted as month interval type.
If a year-month interval data is casted as month interval, the value of the year is multiplied by `12` and added to the value of month. For example, `INTERVAL '1-2' YEAR TO MONTH` will be `INTERVAL '14' MONTH` if  it's casted.
If this behavior is intended, it's stringified to be `'INTERVAL 14' MONTH` but currently, it will be `INTERVAL '2' MONTH`

### Why are the changes needed?

It'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-35771 (#32924).

Liang-Chi Hsieh 882122d6b7 [SPARK-35565][SS] Add config for ignoring metadata directory of FileStreamSink
### What changes were proposed in this pull request?

This patch proposes to add an internal config for ignoring metadata of `FileStreamSink` when reading the output path.

### Why are the changes needed?

`FileStreamSink` produces a metadata directory which logs output files per micro-batch. When we read from the output path, Spark will look at the metadata and ignore other files not in the log.

Normally it works well. But for some use-cases, we may need to ignore the metadata when reading the output path. For example, when we change the streaming query and must to run it with new checkpoint directory, we cannot use previous metadata. If we create a new metadata too, when we read the output path later in Spark, Spark only reads the files listed in the new metadata. The files written before we use new checkpoint and metadata are ignored by Spark.

Although seems we can output to different output directory every time, but it is bad idea as we will produce many directories unnecessarily.

We need a config for ignoring the metadata of `FileStreamSink` when reading the output path.

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

Added a config for ignoring metadata of FileStreamSink when reading the output.

### What changes were proposed in this pull request?
This PR is a follow-up for SPARK-34382. It refines the lateral join syntax to only allow the LATERAL keyword to be in front of subqueries, instead of all `relationPriamry`. For example, `SELECT * FROM t1, LATERAL t2` should not be allowed.

### Why are the changes needed?

Yes. After this PR, the LATERAL keyword can only be in front of subqueries.

Linhong Liu b86a69f026 [SPARK-35792][SQL] View should not capture configs used in RelationConversions
### What changes were proposed in this pull request?
`RelationConversions` is actually an optimization rule while it's executed in the analysis phase.
For view, it's designed to only capture semantic configs, so we should ignore the optimization
configs that will be used in the analysis phase.

This PR also fixes the issue that view resolution will always use the default value for uncaptured config

Wenchen Fan 0c5a01a78c [SPARK-35378][SQL][FOLLOWUP] Restore the command execution name for DataFrameWriterV2
### What changes were proposed in this pull request?

This is a followup of https://github.com/apache/spark/pull/32513

It's hard to keep the command execution name for `DataFrameWriter`, as the command logical plan is a bit messy (DS v1, file source and hive and different command logical plans) and sometimes it's hard to distinguish "insert" and "save".

However, `DataFrameWriterV2` only produce v2 commands which are pretty clean. It's easy to keep the command execution name for them.

Venki Korukanti 8e594f084a [SPARK-35763][SS] Remove the StateStoreCustomMetric subclass enumeration dependency
### What changes were proposed in this pull request?

Remove the usage of the enumerating subclasses of `StateStoreCustomMetric` dependency.

To achieve it, add couple of utility methods to `StateStoreCustomMetric`
* `withNewDesc(desc : String)` to `StateStoreCustomMetric` for cloning the instance with a new `desc` (currently used in `SymmetricHashJoinStateManager`)
* `createSQLMetric(sparkContext: sparkContext): SQLMetric` for creating a corresponding `SQLMetric` to show the metric in UI and accumulate at the query level (currently used in `statefulOperator. stateStoreCustomMetrics`)

### Why are the changes needed?

Code in [SymmetricHashJoinStateManager](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/state/SymmetricHashJoinStateManager.scala#L321) and [StateStoreWriter](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/statefulOperators.scala#L129) rely on the subclass implementations of [StateStoreCustomMetric](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/state/StateStore.scala#L187).

If a new subclass of `StateStoreCustomMetric` is added, it requires code changes to `SymmetricHashJoinStateManager` and `StateStoreWriter`, and we may miss the update if there is no existing test coverage.

To prevent these issues add a couple of utility methods to `StateStoreCustomMetric` as mentioned above.

Wenchen Fan a2961ddfdf [SPARK-35712][SQL] Simplify ResolveAggregateFunctions
### What changes were proposed in this pull request?

Currently, `ResolveAggregateFunctions` is a complicated rule that recursively calls the entire analyzer to resolve aggregate functions in parent nodes of aggregate. It's kind of necessary as we need to do many things to identify the aggregate function and push it down to the aggregate node: resolve columns as if they are in the aggregate node, resolve functions, apply type coercion, etc. However, this is overly complicated and it's hard to fully understand how the resolution is done there. It also leads to hacks such as the [char/varchar hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2396-L2401), [subquery hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2274-L2277), [grouping function hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2465-L2467), etc.

This PR simplifies the `ResolveAggregateFunctions` rule and clarifies the resolution logic. To resolve aggregate functions/grouping columns in HAVING, ORDER BY and `df.where`, we expand the aggregate node below to output these required aggregate functions/grouping columns. In details, when resolving an expression from the parent of an aggregate node:
1. try to resolve columns with `agg.child` and wrap the result with `TempResolvedColumn`.
2. try to resolve subqueries with `agg.child`
3. if the expression is not resolved, return it and wait for other rules to resolve it, such as resolve functions, type coercions, etc.
4. if the expression is resolved, we transform it and push aggregate functions/grouping columns into the aggregate node below.
4.1 the expression may already present in `agg.aggregateExpressions`, we can simply replace the expression with attr ref.
4.2 if a `TempResolvedColumn` is neither inside an aggregate function, or wrap a grouping column, turn it back to an `UnresolvedAttribute`
5. after the main resolution batch, remove all `TempResolvedColumn` and turn them back to `UnresolvedAttribute`.

Venkata krishnan Sowrirajan aaa8a80c9d [SPARK-35613][CORE][SQL] Cache commonly occurring strings in SQLMetrics, JSONProtocol and AccumulatorV2 classes
### What changes were proposed in this pull request?
Cache commonly occurring duplicate Some objects in SQLMetrics by using a Guava cache and reusing the existing Guava String Interner to avoid duplicate strings in JSONProtocol. Also with AccumulatorV2 we have seen lot of Some(-1L) and Some(0L) occurrences in a heap dump that is naively interned by having reusing a already constructed Some(-1L) and Some(0L)

To give some context on the impact and the garbage got accumulated, below are the details of the complex spark job which we troubleshooted and figured out the bottlenecks. **tl;dr - In short, major issues were the accumulation of duplicate objects mainly from SQLMetrics.**

Greater than 25% of the 40G driver heap filled with (a very large number of) **duplicate**, immutable objects.

1. Very large number of **duplicate** immutable objects.

- Type of metric is represented by `'scala.Some("sql")'` - which is created for each metric.
- Fixing this reduced memory usage from 4GB to a few bytes.

2. `scala.Some(0)` and `scala.Some(-1)` are very common metric values (typically to indicate absence of metric)

- Individually the values are all immutable, but spark sql was creating a new instance each time.
- Intern'ing these resulted in saving ~4.5GB for a 40G heap.

3. Using string interpolation for metric names.

- Interpolation results in creation of a new string object.
- We end up with a very large number of metric names - though the number of unique strings is miniscule.
- ~7.5 GB in the 40 GB heap : which went down to a few KB's when fixed.

### Why are the changes needed?
To reduce overall driver memory footprint which eventually reduces the Full GC pauses.

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

### How was this patch tested?
Since these are memory related optimizations, unit tests are not added. These changes are added in our internal platform which made it possible for one of the complex spark job continuously failing to succeed along with other set of optimizations.

Wenchen Fan 11e96dc843 [SPARK-35669][SQL] Quote the pushed column name only when nested column predicate pushdown is enabled
### What changes were proposed in this pull request?

This is a followup of https://github.com/apache/spark/pull/31964

We should only quote the column name when nested column predicate pushdown is enabled, otherwise the data source side may not have the logic to parse the quoted column name and fail. This is not a problem before #31964 , as we don't quote the column name if there is no dot in the name. But #31964 changed it.

Cheng Su 9709ee5ffd [SPARK-35760][SQL] Fix the max rows check for broadcast exchange
### What changes were proposed in this pull request?

This is to fix the maximal allowed number of rows check in `BroadcastExchangeExec`. After https://github.com/apache/spark/pull/27828, the max number of rows is calculated based on max capacity of `BytesToBytesMap` (previous value before the PR is 512000000). This calculation is not accurate as only `UnsafeHashedRelation` is using `BytesToBytesMap`. `LongHashedRelation` (used for broadcast join on key with long data type) has limit of [512000000](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/HashedRelation.scala#L584), and `BroadcastNestedLoopJoinExec` is not depending on `HashedRelation` at all.

The change is to only specialize the max rows limit when needed. Keep other broadcast case with the previous limit - 512000000.

### Why are the changes needed?

Fix code logic and avoid unexpected behavior.

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

No.

### How was this patch tested?

Sumeet Gajjar 864ff67746 [SPARK-35429][CORE] Remove commons-httpclient from Hadoop-3.2 profile due to EOL and CVEs
### What changes were proposed in this pull request?

Remove commons-httpclient as a direct dependency for Hadoop-3.2 profile.
Hadoop-2.7 profile distribution still has it, hadoop-client has a compile dependency on commons-httpclient, thus we cannot remove it for Hadoop-2.7 profile.
```
[INFO] +- org.apache.hadoop:hadoop-client:jar:2.7.4:compile
[INFO] |  +- org.apache.hadoop:hadoop-common:jar:2.7.4:compile

[INFO] |  |  +- xmlenc:xmlenc:jar:0.52:compile
[INFO] |  |  +- commons-httpclient:commons-httpclient:jar:3.1:compile
```

### Why are the changes needed?

Spark is pulling in commons-httpclient as a dependency directly. commons-httpclient went EOL years ago and there are most likely CVEs not being reported against it, thus we should remove it.

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

No

### How was this patch tested?

- Existing unittests
- Checked the dependency tree before and after introducing the changes

Before:
```
./build/mvn dependency:tree -Phadoop-3.2 | grep -i "commons-httpclient"
Using `mvn` from path: /usr/bin/mvn
[INFO] +- commons-httpclient:commons-httpclient:jar:3.1:compile
[INFO] |  +- commons-httpclient:commons-httpclient:jar:3.1:provided
```

After
```
./build/mvn dependency:tree | grep -i "commons-httpclient"
Using `mvn` from path: /Users/sumeet.gajjar/cloudera/upstream-spark/build/apache-maven-3.6.3/bin/mvn
```

P.S. Reopening this since [spark upgraded](463daabd5a) its `hive.version` to `2.3.9` which does not have a dependency on `commons-httpclient`.

Max Gekk 61ce8f7649 [SPARK-35680][SQL] Add fields to YearMonthIntervalType
### What changes were proposed in this pull request?
Extend `YearMonthIntervalType` to support interval fields. Valid interval field values:
- 0 (YEAR)
- 1 (MONTH)

After the changes, the following year-month interval types are supported:
1. `YearMonthIntervalType(0, 0)` or `YearMonthIntervalType(YEAR, YEAR)`
2. `YearMonthIntervalType(0, 1)` or `YearMonthIntervalType(YEAR, MONTH)`. **It is the default one**.
3. `YearMonthIntervalType(1, 1)` or `YearMonthIntervalType(MONTH, MONTH)`

### Does this PR introduce _any_ user-facing change?
Yes but `YearMonthIntervalType` has not been released yet.

Kousuke Saruta aab0c2bf66 [SPARK-35736][SPARK-35737][SQL][FOLLOWUP] Move a common logic to DayTimeIntervalType
### What changes were proposed in this pull request?

This is a followup PR for SPARK-35736(#32893) and SPARK-35737(#32892).
This PR moves a common logic to `object DayTimeIntervalType`.
That logic is like `val strToFieldIndex = DayTimeIntervalType.dayTimeFields.map(i => DayTimeIntervalType.fieldToString(i) -> (i).toMap`, a `Map` which maps each time unit to the corresponding day-time field index.

### Why are the changes needed?

Chao Sun 9c7250fa73 [SPARK-35321][SQL] Don't register Hive permanent functions when creating Hive client
### What changes were proposed in this pull request?

Instantiate a new Hive client through `Hive.getWithoutRegisterFns(conf, false)` instead of `Hive.get(conf)`, if `Hive` version is >= '2.3.9' (the built-in version).

### Why are the changes needed?

[HIVE-10319](https://issues.apache.org/jira/browse/HIVE-10319) introduced a new API `get_all_functions` which is only supported in Hive 1.3.0/2.0.0 and up. As result, when Spark 3.x talks to a HMS service of version 1.2 or lower, the following error will occur:
```
Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: org.apache.thrift.TApplicationException: Invalid method name: 'get_all_functions'
        at org.apache.hadoop.hive.ql.metadata.Hive.getAllFunctions(Hive.java:3897)
        at org.apache.hadoop.hive.ql.metadata.Hive.reloadFunctions(Hive.java:248)
        at org.apache.hadoop.hive.ql.metadata.Hive.registerAllFunctionsOnce(Hive.java:231)
        ... 96 more
Caused by: org.apache.thrift.TApplicationException: Invalid method name: 'get_all_functions'
        at org.apache.thrift.TServiceClient.receiveBase(TServiceClient.java:79)
        at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.recv_get_all_functions(ThriftHiveMetastore.java:3845)
        at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.get_all_functions(ThriftHiveMetastore.java:3833)
```

The `get_all_functions` is called only when `doRegisterAllFns` is set to true:
```java
  private Hive(HiveConf c, boolean doRegisterAllFns) throws HiveException {
    conf = c;
    if (doRegisterAllFns) {
      registerAllFunctionsOnce();
    }
  }
```

what this does is to register all Hive permanent functions defined in HMS in Hive's `FunctionRegistry` class, via iterating through results from `get_all_functions`. To Spark, this seems unnecessary as it loads Hive permanent (not built-in) UDF via directly calling the HMS API, i.e., `get_function`. The `FunctionRegistry` is only used in loading Hive's built-in function that is not supported by Spark. At this time, it only applies to `histogram_numeric`.

[HIVE-21563](https://issues.apache.org/jira/browse/HIVE-21563) introduced a new API `getWithoutRegisterFns` which skips the above registration and is available in Hive 2.3.9. Therefore, Spark should adopt it to avoid the cost.

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

Yes with this fix Spark now should be able to talk to HMS server with Hive 1.2.x and lower.

### How was this patch tested?

Manually started a HMS server of Hive version 1.2.2. Without the PR it failed with the above exception. With the PR the error disappeared and I can successfully perform common operations such as create table, create database, list tables, etc.

4. `DayTimeIntervalType(0, 3)` or `DayTimeIntervalType(DAY, SECOND)`. **It is the default one**. The second fraction precision is microseconds.
5. `DayTimeIntervalType(1, 1)` or `DayTimeIntervalType(HOUR, HOUR)`

RoryQi 57ce64c511 [SPARK-35706][SQL] Consider making the ':' in STRUCT data type definition optional
### What changes were proposed in this pull request?

The STRUCT type syntax is defined like this:

STRUCT(fieldNmae: fileType [NOT NULL][COMMENT stringLiteral][,.....])

So the field list is nearly the same as a column list

if we could make ':' optional it would be so much cleaner an less proprietary

### Why are the changes needed?
ease of use

### Does this PR introduce _any_ user-facing change?
Yes, you can use Struct type list is nearly the same as a column list

### How was this patch tested?
unit tests

Closes #32858 from jerqi/master.

dgd-contributor 6e1aa15679 [SPARK-35652][SQL] joinWith on two table generated from same one
### What changes were proposed in this pull request?
It seems like spark inner join is performing a cartesian join in self joining using `joinWith`

To produce this issues:
```
val df = spark.range(0,3)
df.joinWith(df, df("id") === df("id")).show()
```

Chao Sun e9ccf4a50c [SPARK-35640][SQL] Refactor Parquet vectorized reader to remove duplicated code paths
### What changes were proposed in this pull request?

1. Remove duplicated code in the form of `readXXX` in `VectorizedRleValuesReader`. For instance:
```java
  public void readIntegers(
      int total,
      WritableColumnVector c,
      int rowId,
      int level,
      VectorizedValuesReader data) throws IOException {
    int left = total;
    while (left > 0) {
      if (this.currentCount == 0) this.readNextGroup();
      int n = Math.min(left, this.currentCount);
      switch (mode) {
        case RLE:
          if (currentValue == level) {
            data.readIntegers(n, c, rowId);
          } else {
            c.putNulls(rowId, n);
          }
          break;
        case PACKED:
          for (int i = 0; i < n; ++i) {
            if (currentBuffer[currentBufferIdx++] == level) {
              c.putInt(rowId + i, data.readInteger());
            } else {
              c.putNull(rowId + i);
            }
          }
          break;
      }
      rowId += n;
      left -= n;
      currentCount -= n;
    }
  }
```
and replace with:
```java
  public void readBatch(
       int total,
       int offset,
       WritableColumnVector values,
       int maxDefinitionLevel,
       VectorizedValuesReader valueReader,
       ParquetVectorUpdater updater) throws IOException {
     int left = total;
     while (left > 0) {
       if (this.currentCount == 0) this.readNextGroup();
       int n = Math.min(left, this.currentCount);
       switch (mode) {
         case RLE:
           if (currentValue == maxDefinitionLevel) {
             updater.updateBatch(n, offset, values, valueReader);
           } else {
             values.putNulls(offset, n);
           }
           break;
         case PACKED:
           for (int i = 0; i < n; ++i) {
             if (currentBuffer[currentBufferIdx++] == maxDefinitionLevel) {
               updater.update(offset + i, values, valueReader);
             } else {
               values.putNull(offset + i);
             }
           }
           break;
       }
       offset += n;
       left -= n;
       currentCount -= n;
     }
   }
```
where the `ParquetVectorUpdater` is type specific, and has different implementations under `updateBatch` and `update`. Together, this also changes code paths handling timestamp types to use the batch read API for decoding definition levels.

2. Similar to the above, this removes code duplication in `VectorizedColumnReader.decodeDictionaryIds`. Now different implementations are under `ParquetVectorUpdater.decodeSingleDictionaryId`.

### Why are the changes needed?

`VectorizedRleValuesReader` and `VectorizedColumnReader` are becoming increasingly harder to maintain, as any change touches the above logic **will need to be replicated in 20+ places**. The issue becomes even more serious when we are going to implement column index (for instance, see how the change [here](https://github.com/apache/spark/pull/32753/files#diff-a01e174e178366aadf07f64ee690d47d343b2ca416a4a2b2ea735887c22d5934R191) has to be replicated multiple times) and complex type support (in progress) for the vectorized path.

In addition, currently dictionary decoding (see `VectorizedColumnReader.decodeDictionaryIds`) and non-dictionary decoding are handled separately, and therefore the same (very complicated) branching logic based on input Spark & Parquet types have to be replicated in two places, which is another burden for code maintenance.

The original intention is for performance. However these days JIT compilers tend to be very effective on this and will inline virtual calls aggressively to eliminate the method invocation costs (see [this](https://shipilev.net/blog/2015/black-magic-method-dispatch/) and [this](http://insightfullogic.com/blog/2014/may/12/fast-and-megamorphic-what-influences-method-invoca/)). I've also done benchmarks using a modified `DataSourceReadBenchmark` and `DateTimeRebaseBenchmark` and the result is almost exact the same before and after the change. The results can be found [here](https://gist.github.com/sunchao/674afbf942ccc2370bdcfa33efb4471c), and [here's](https://github.com/sunchao/spark/tree/parquet-refactor) the source code.

Kousuke Saruta 44b695fbb0 [SPARK-35296][SQL] Allow Dataset.observe to work even if CollectMetricsExec in a task handles multiple partitions
### What changes were proposed in this pull request?

This PR fixes an issue that `Dataset.observe` doesn't work if `CollectMetricsExec` in a task handles multiple partitions.
If `coalesce` follows `observe` and the number of partitions shrinks after `coalesce`, `CollectMetricsExec` can handle multiple partitions in a task.

### Why are the changes needed?

The current implementation of `CollectMetricsExec` doesn't consider the case it can handle multiple partitions.
Because new `updater` is created for each partition even though those partitions belong to the same task, `collector.setState(updater)` raise an assertion error.
This is a simple reproducible example.
```
$ bin/spark-shell --master "local[1]"
scala> spark.range(1, 4, 1, 3).observe("my_event", count($"id").as("count_val")).coalesce(2).collect
```

So using a map with cases classes for keys or values and using the interpreted path would incorrect deserialize data from the catalyst representation.

dgd-contributor aa3de40773 [SPARK-35679][SQL] instantToMicros overflow
### Why are the changes needed?
With Long.minValue cast to an instant, secs will be floored in function microsToInstant and cause overflow when multiply with Micros_per_second

```
def microsToInstant(micros: Long): Instant = {
  val secs = Math.floorDiv(micros, MICROS_PER_SECOND)
  // Unfolded Math.floorMod(us, MICROS_PER_SECOND) to reuse the result of
  // the above calculation of `secs` via `floorDiv`.
  val mos = micros - secs * MICROS_PER_SECOND  <- it will overflow here
  Instant.ofEpochSecond(secs, mos * NANOS_PER_MICROS)
}
```

But the overflow is acceptable because it won't produce any change to the result

However, when convert the instant back to micro value, it will raise Overflow Error

```
def instantToMicros(instant: Instant): Long = {
  val us = Math.multiplyExact(instant.getEpochSecond, MICROS_PER_SECOND) <- It overflow here
  val result = Math.addExact(us, NANOSECONDS.toMicros(instant.getNano))
  result
}
```

Code to reproduce this error
```
instantToMicros(microToInstant(Long.MinValue))
```

Kousuke Saruta 94b66f5e28 [MINOR][SQL] Modify the example of rand and randn
### What changes were proposed in this pull request?

This PR fixes the examples of `rand` and `randn`.

### Why are the changes needed?

SPARK-23643 (#20793) fixes an issue which is related to the seed and it causes the result of `rand` and `randn`.
Now the results of `SELECT rand(0)` and `SELECT randn((null)` are `0.7604953758285915` and `1.6034991609278433` respectively, and they should be deterministic because the number of partitions are always 1 (the leaf node is `OneRowRelation`).

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

No.

### How was this patch tested?

allisonwang-db f49bf1a072 [SPARK-34382][SQL] Support LATERAL subqueries
### What changes were proposed in this pull request?
This PR adds support for lateral subqueries. A lateral subquery is a subquery preceded by the `LATERAL` keyword in the FROM clause of a query that can reference columns in the preceding FROM items. For example:
```sql
SELECT * FROM t1, LATERAL (SELECT * FROM t2 WHERE t1.a = t2.c)
```
A new subquery expression`LateralSubquery` is used to represent a lateral subquery. It is similar to `ScalarSubquery` but can return multiple rows and columns. A new logical unary node `LateralJoin` is used to represent a lateral join.

Here is the analyzed plan for the above query:
```scala
Project [a, b, c, d]
+- LateralJoin lateral-subquery [a], Inner
   :  +- Project [c, d]
   :     +- Filter (outer(a) = c)
   :        +- Relation [c, d]
   +- Relation [a, b]
```

Similar to a correlated subquery, a lateral subquery can be viewed as a dependent (nested loop) join where the evaluation of the right subtree depends on the current value of the left subtree.  The same technique to decorrelate a subquery is used to decorrelate a lateral join:
```scala
Project [a, b, c, d]
+- LateralJoin lateral-subquery [a && a = c], Inner  // pull up correlated predicates as join conditions
   :  +- Project [c, d]
   :     +- Relation [c, d]
   +- Relation [a, b]
```
Then the lateral join can be rewritten into a normal join:
```scala
Join Inner (a = c)
:- Relation [a, b]
+- Relation [c, d]
```

#### Follow-ups:
1. Similar to rewriting correlated scalar subqueries, rewriting lateral joins is also subject to the COUNT bug (See SPARK-15370 for more details). This is **not** handled in the current PR as it requires a sizeable amount of refactoring. It will be addressed in a subsequent PR (SPARK-35551).
2. Currently Spark does use outer query references to resolve star expressions in subqueries. This is not lateral subquery specific and can be handled in a separate PR (SPARK-35618)

### Why are the changes needed?
To support an ANSI SQL feature.

### Does this PR introduce _any_ user-facing change?
Yes. It allows users to use lateral subqueries in the FROM clause of a query.

### How was this patch tested?
- Parser test: `PlanParserSuite.scala`
- Analyzer test: `ResolveSubquerySuite.scala`
- Optimizer test: `PullupCorrelatedPredicatesSuite.scala`
- SQL test: `join-lateral.sql`, `postgreSQL/join.sql`

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

Handle type coercion when resolving V2 function. In particular:
- prior to evaluating function arguments, insert cast whenever the argument type doesn't match the expected input type.
- use `BoundFunction.inputTypes()` to lookup magic method for scalar function

### Why are the changes needed?

For V2 functions, the actual argument types should not necessarily match those of the input types, and Spark should handle type coercion whenever it is needed.

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

Yes. Now V2 function resolution should be able to handle type coercion properly.

Yuming Wang ce1636948b [SPARK-35650][SQL] Enhance RepartitionByExpression to make it coalesce partitions efficiently by AQE
### What changes were proposed in this pull request?

This PR enhances `RepartitionByExpression` to make it coalesce partitions efficiently by AQE. Usually used to merge small files.
The basic logic is: Spark first tries to coalesce partitions, if it cannot be coalesced, then use the local shuffle reader to read data to avoid exchange the data over the network.

Usage:
```sql
SELECT /*+ REPARTITION */ * FROM t
```
```scala
df.repartition()
```

For example:
coalesce small output files | local shuffle reader

Gengliang Wang 84c5ca33f9 [SPARK-35664][SQL] Support java.time.LocalDateTime as an external type of TimestampWithoutTZ type
### What changes were proposed in this pull request?

In the PR, I propose to extend Spark SQL API to accept `java.time.LocalDateTime` as an external type of recently added new Catalyst type - `TimestampWithoutTZ`. The Java class `java.time.LocalDateTime` has a similar semantic to ANSI SQL timestamp without timezone type, and it is the most suitable to be an external type for `TimestampWithoutTZType`. In more details:

* Added `TimestampWithoutTZConverter` which converts java.time.LocalDateTime instances to/from internal representation of the Catalyst type `TimestampWithoutTZType` (to Long type). The `TimestampWithoutTZConverter` object uses new methods of DateTimeUtils:
  * localDateTimeToMicros() converts the input date time to the total length in microseconds.
  * microsToLocalDateTime() obtains a java.time.LocalDateTime
* Support new type `TimestampWithoutTZType` in RowEncoder via the methods createDeserializerForLocalDateTime() and createSerializerForLocalDateTime().
* Extended the Literal API to construct literals from `java.time.LocalDateTime` instances.

### Why are the changes needed?

To allow users parallelization of `java.time.LocalDateTime` collections, and construct timestamp without time zone columns. Also to collect such columns back to the driver side.

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

The PR extends existing functionality. So, users can parallelize instances of the java.time.LocalDateTime class and collect them back.
```
scala> val ds = Seq(java.time.LocalDateTime.parse("1970-01-01T00:00:00")).toDS
ds: org.apache.spark.sql.Dataset[java.time.LocalDateTime] = [value: timestampwithouttz]

scala> ds.collect()
res0: Array[java.time.LocalDateTime] = Array(1970-01-01T00:00)
```

gengjiaan 8013f985a4 [SPARK-35378][SQL] Eagerly execute commands in QueryExecution instead of caller sides
### What changes were proposed in this pull request?
Currently, Spark eagerly executes commands on the caller side of `QueryExecution`, which is a bit hacky as `QueryExecution` is not aware of it and leads to confusion.

For example, if you run `sql("show tables").collect()`, you will see two queries with identical query plans in the web UI.
![image](https://user-images.githubusercontent.com/3182036/121193729-a72d0480-c8a0-11eb-8b12-379019607ad5.png)
![image](https://user-images.githubusercontent.com/3182036/121193822-bc099800-c8a0-11eb-9d2a-34ab1329e2f7.png)
![image](https://user-images.githubusercontent.com/3182036/121193845-c0ce4c00-c8a0-11eb-96d0-ef604a4dfab0.png)

The first query is triggered at `Dataset.logicalPlan`, which eagerly executes the command.
The second query is triggered at `Dataset.collect`, which is the normal query execution.

From the web UI, it's hard to tell that these two queries are caused by eager command execution.

This PR proposes to move the eager command execution to `QueryExecution`, and turn the command plan to `CommandResult` to indicate that command has been executed already. Now `sql("show tables").collect()` still triggers two queries, but the quey plans are not identical. The second query becomes:
![image](https://user-images.githubusercontent.com/3182036/121194850-b3659180-c8a1-11eb-9abf-2980f84f089d.png)

In addition to the UI improvements, this PR also has other benefits:
1. Simplifies code as caller side no need to worry about eager command execution. `QueryExecution` takes care of it.
2. It helps https://github.com/apache/spark/pull/32442 , where there can be more plan nodes above commands, and we need to replace commands with something like local relation that produces unsafe rows.

### Why are the changes needed?
Explained above.

No

Kousuke Saruta 93a9dc479c [SPARK-35602][SS] Update state schema to be able to accept long length JSON
### What changes were proposed in this pull request?

This PR fixes an issue that both key and value of state schema cannot accept long length (>65535 bytes) JSON.
To solve the problem explained below, JSON represented schema is divided into chunks whose maximum length is 65535 bytes, and each chunk is written by `DataOutputStream.writeUTF`.

As the solution changes the format of the schema, the version is also changes from `1` to `2` but old version schema is still acceptable to ensures backward compatibility.

### Why are the changes needed?

In the current implementation, writing state schema fails if the length of schema exceeds 65535 bytes and `UTFDataFormatException` is thrown.
It's due to the limitation of `DataOutputStream.writeUTF`.
`writeUTF` writes a length field first and it's 2 bytes width, meaning the maximum content length is limited to `2^16-1`=`65535` bytes.

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

This patch removes the usage of putting null into StateStore.

### Why are the changes needed?

According to `get` method doc in `StateStore` API, it returns non-null row if the key exists. So basically we should avoid write null to `StateStore`. You cannot distinguish if the returned null row is because the key doesn't exist, or the value is actually null. And due to the defined behavior of `get`, it is quite easy to cause NPE error if the caller doesn't expect to get a null if the caller believes the key exists.

Satish Gopalani 2a331177ba [SPARK-35312][SS] Introduce new Option in Kafka source to specify minimum number of records to read per trigger
### What changes were proposed in this pull request?
This patch introduces a new option to specify the minimum number of offsets to read per trigger i.e. minOffsetsPerTrigger and maxTriggerDelay to avoid the infinite wait for the trigger.

This new option will allow skipping trigger/batch when the number of records available in Kafka is low. This is a very useful feature in cases where we have a sudden burst of data at certain intervals in a day and data volume is low for the rest of the day.
'maxTriggerDelay' option will help to avoid cases of infinite delay in scheduling trigger and the trigger will happen irrespective of records available if the maxTriggerDelay time exceeds the last trigger. It would be an optional parameter with a default value of 15 mins. This option will be only applicable if minOffsetsPerTrigger is set.

minOffsetsPerTrigger option would be optional of course, but once specified it would take precedence over maxOffestsPerTrigger which will be honored only after minOffsetsPerTrigger is satisfied.

### Why are the changes needed?
There are many scenarios where there is a sudden burst of data at certain intervals in a day and data volume is low for the rest of the day. Tunning such jobs is difficult as decreasing trigger processing time increasing the number of batches and hence cluster resource usage and adds to small file issues. Increasing trigger processing time adds consumer lag. This patch tries to address this issue.

### How was this patch tested?
This patch was tested by adding test cases as well as manually on a cluster where the job was running for a full one day with a data burst happening once a day.
Here is the picture of databurst and hence consumer lag:
<img width="1198" alt="Screenshot 2021-04-29 at 11 39 35 PM" src="https://user-images.githubusercontent.com/1044003/116997587-9b2ab180-acfa-11eb-91fd-524802ce3316.png">

This is how the job behaved at burst time running every 4.5 mins (which is the specified trigger time):
<img width="1154" alt="Burst Time" src="https://user-images.githubusercontent.com/1044003/116997919-12f8dc00-acfb-11eb-9b0a-98387fc67560.png">

This is job behavior during the non-burst time where it is skipping 2 to 3 triggers and running once every 9 to 13.5 mins
<img width="1154" alt="Non Burst Time" src="https://user-images.githubusercontent.com/1044003/116998244-8b5f9d00-acfb-11eb-8340-33d47149ef81.png">

Here are some more stats from the two-run i.e. one normal run and the other with minOffsetsperTrigger set:

| Run | Data Size | Number of Batch Runs | Number of Files |
| ------------- | ------------- |------------- |------------- |
| Normal Run | 54.2 GB | 320 | 21968 |
| Run with minOffsetsperTrigger | 54.2 GB | 120 | 12104 |

Gengliang Wang 33f26275f4 [SPARK-35663][SQL] Add Timestamp without time zone type
### What changes were proposed in this pull request?

Extend Catalyst's type system by a new type that conforms to the SQL standard (see SQL:2016, section 4.6.2): TimestampWithoutTZType represents the timestamp without time zone type

### Why are the changes needed?

Spark SQL today supports the TIMESTAMP data type. However the semantics provided actually match TIMESTAMP WITH LOCAL TIMEZONE as defined by Oracle. Timestamps embedded in a SQL query or passed through JDBC are presumed to be in session local timezone and cast to UTC before being processed.
These are desirable semantics in many cases, such as when dealing with calendars.
In many (more) other cases, such as when dealing with log files it is desirable that the provided timestamps not be altered.
SQL users expect that they can model either behavior and do so by using TIMESTAMP WITHOUT TIME ZONE for time zone insensitive data and TIMESTAMP WITH LOCAL TIME ZONE for time zone sensitive data.
Most traditional RDBMS map TIMESTAMP to TIMESTAMP WITHOUT TIME ZONE and will be surprised to see TIMESTAMP WITH LOCAL TIME ZONE, a feature that does not exist in the standard.

In this new feature, we will introduce TIMESTAMP WITH LOCAL TIMEZONE to describe the existing timestamp type and add TIMESTAMP WITHOUT TIME ZONE for standard semantic.
Using these two types will provide clarity.
This is a starting PR. See more details in https://issues.apache.org/jira/browse/SPARK-35662

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

Yes, a new data type for Timestamp without time zone type. It is still in development.

### How was this patch tested?

Wenchen Fan a70e66ecfa [SPARK-35665][SQL] Resolve UnresolvedAlias in CollectMetrics
### What changes were proposed in this pull request?

It's a long-standing bug that we forgot to resolve `UnresolvedAlias` in `CollectMetrics`. It's a bit hard to trigger this bug before 3.2 as most likely people won't create `UnresolvedAlias` when calling `Dataset.observe`. However things have been changed after https://github.com/apache/spark/pull/30974

This PR proposes to handle `CollectMetrics` in the rule `ResolveAliases`.

Alkis Polyzotis 6f8c62047c [SPARK-35558] Optimizes for multi-quantile retrieval
### What changes were proposed in this pull request?
Optimizes the retrieval of approximate quantiles for an array of percentiles.
* Adds an overload for QuantileSummaries.query that accepts an array of percentiles and optimizes the computation to do a single pass over the sketch and avoid redundant computation.
* Modifies the ApproximatePercentiles operator to call into the new method.

All formatting changes are the result of running ./dev/scalafmt

### Why are the changes needed?
The existing implementation does repeated calls per input percentile resulting in redundant computation.

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

### How was this patch tested?
Added unit tests for the new method.

Marios Meimaris b5678bee1e [SPARK-35446] Override getJDBCType in MySQLDialect to map FloatType to FLOAT
### What changes were proposed in this pull request?

Override `getJDBCType` method in `MySQLDialect` so that `FloatType` is mapped to `FLOAT` instead of `REAL`

### Why are the changes needed?

MySQL treats `REAL` as a synonym to `DOUBLE` by default (see https://dev.mysql.com/doc/refman/8.0/en/numeric-types.html). Therefore, when creating a table with a column of `REAL` type, it will be created as `DOUBLE`. However, currently, `MySQLDialect` does not provide an implementation for `getJDBCType`, and will thus ultimately fall back to `JdbcUtils.getCommonJDBCType`, which maps `FloatType` to `REAL`. This change is needed so that we can properly map the `FloatType` to `FLOAT` for MySQL.

### Does this PR introduce _any_ user-facing change?
Prior to this PR, when writing a dataframe with a `FloatType` column to a MySQL table, it will create a `DOUBLE` column. After the PR, it will create a `FLOAT` column.

### How was this patch tested?
Added a test case in `JDBCSuite` that verifies the mapping.

Ke Jia 6ce5f2491c [SPARK-35568][SQL] Add the BroadcastExchange after re-optimizing the physical plan to fix the UnsupportedOperationException when enabling both AQE and DPP

This PR is to fix the `UnsupportedOperationException` described in [PR#32705](https://github.com/apache/spark/pull/32705).
When AQE and DPP are turned on at the same time, because the `BroadcastExchange` included in the DPP filter is not added through `EnsureRequirement` rule, Therefore, when AQE optimizes the DPP filter, there is no way to add `BroadcastExchange` through the `EnsureRequirement` rule in `reOptimize` method, which eventually leads to the loss of `BroadcastExchange` in the final physical plan.

Karen Feng 53a758b51b [SPARK-35636][SQL] Lambda keys should not be referenced outside of the lambda function
### What changes were proposed in this pull request?

Sets `references` for `NamedLambdaVariable` and `LambdaFunction`.

| Expression  | NamedLambdaVariable | LambdaFunction |
| --- | --- | --- |
| References before | None | All function references |
| References after | self.toAttribute | Function references minus arguments' references |

In `NestedColumnAliasing`, this means that `ExtractValue(ExtractValue(attr, lv: NamedLambdaVariable), ...)` now references both `attr` and `lv`, rather than just `attr`. As a result, it will not be included in the nested column references.

### Why are the changes needed?

Before, lambda key was referenced outside of lambda function.

#### Example 1

Before:
```
Project [transform(keys#0, lambdafunction(_extract_v1#0, lambda key#0, false)) AS a#0]
+- 'Join Cross
   :- Project [kvs#0[lambda key#0].v1 AS _extract_v1#0]
   :  +- LocalRelation <empty>, [kvs#0]
   +- LocalRelation <empty>, [keys#0]
```

After:
```
Project [transform(keys#418, lambdafunction(kvs#417[lambda key#420].v1, lambda key#420, false)) AS a#419]
+- Join Cross
   :- LocalRelation <empty>, [kvs#417]
   +- LocalRelation <empty>, [keys#418]
```

#### Example 2

Before:
```
Project [transform(keys#0, lambdafunction(kvs#0[lambda key#0].v1, lambda key#0, false)) AS a#0]
+- GlobalLimit 5
  +- LocalLimit 5
    +- Project [keys#0, _extract_v1#0 AS _extract_v1#0]

          +- Project [kvs#0[lambda key#0].v1 AS _extract_v1#0, keys#0]
            +- LocalRelation <empty>, [kvs#0, keys#0]
```

After:
```

Liang-Chi Hsieh 0342dcb628 [SPARK-35580][SQL] Implement canonicalized method for HigherOrderFunction
### What changes were proposed in this pull request?

This patch implements `canonicalized` method for `HigherOrderFunction`. Basically it canonicalizes the name of all `NamedLambdaVariable`s and their `ExprId`. The name and `ExprId` of `NamedLambdaVariable` are unque. But to compare semantic equality between `HigherOrderFunction`, we can canonicalize them.

### Why are the changes needed?

The default `canonicalized` method does not work for `HigherOrderFunction`. It makes subexpression elimination not work for higher functions.

Manual check gen-ed code for:
```scala
val df = Seq(Seq(1, 2, 3)).toDF("a")
df.select(transform($"a", x => x + 1), transform($"a", x => x + 1)).collect()
```

The code for `transform(input[0, array<int>, true], lambdafunction((lambda x_20#19041 + 1), lambda x_20#19041, false)),transform(input[0, array<int>, true], lambdafunction((lambda x_21#19042 + 1), lambda x_21#19042, false))`, generated by `GenerateUnsafeProjection`.

Before:

```java
/* 005 */ class SpecificUnsafeProjection extends org.apache.spark.sql.catalyst.expressions.UnsafeProjection {
...
/* 028 */   public UnsafeRow apply(InternalRow i) {
...
/* 034 */     Object obj_0 = ((Expression) references[0]).eval(i);
...
/* 062 */     Object obj_1 = ((Expression) references[1]).eval(i);
...
/* 093 */ }
```

After:
```java
/* 005 */ class SpecificUnsafeProjection extends org.apache.spark.sql.catalyst.expressions.UnsafeProjection {
...
/* 031 */   public UnsafeRow apply(InternalRow i) {
...
/* 033 */     subExpr_0(i);
...
/* 086 */   private void subExpr_0(InternalRow i) {
/* 087 */     Object obj_0 = ((Expression) references[0]).eval(i);
/* 088 */     boolean isNull_0 = obj_0 == null;
/* 089 */     ArrayData value_0 = null;
/* 090 */     if (!isNull_0) {
/* 091 */       value_0 = (ArrayData) obj_0;

Kent Yao 345d35ed1a [SPARK-21957][SQL] Support current_user function
### What changes were proposed in this pull request?

Currently, we do not have a suitable definition of the `user` concept in Spark. We only have a `sparkUser` app widely but do not support identify or retrieve the user information from a session in STS or a runtime query execution.

`current_user()` is very popular and supported by plenty of other modern or old school databases, and also ANSI compliant.

This PR add `current_user()`  as a SQL function. And, they are the same.  In this PR, we add these functions w/o ambiguity.
1. For a normal single-threaded Spark application, clearly the `sparkUser` is always equivalent to `current_user()` .
2. For a multi-threaded Spark application, e.g. Spark thrift server, we use a `ThreadLocal` variable to store the client-side user(after authenticated) before running the query and retrieve it in the parser.

### Why are the changes needed?

`current_user()` is very popular and supported by plenty of other modern or old school databases, and also ANSI compliant.

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

Liang-Chi Hsieh dbf0b50757 [SPARK-35560][SQL] Remove redundant subexpression evaluation in nested subexpressions
### What changes were proposed in this pull request?

This patch proposes to improve subexpression evaluation under whole-stage codegen for the cases of nested subexpressions.

### Why are the changes needed?

In the cases of nested subexpressions, whole-stage codegen's subexpression elimination will do redundant subexpression evaluation. We should reduce it. For example, if we have two sub-exprs:

1. `simpleUDF($"id")`
2. `functions.length(simpleUDF($"id"))`

We should only evaluate `simpleUDF($"id")` once, i.e.

```java
subExpr1 = simpleUDF($"id");
subExpr2 = functions.length(subExpr1);
```

Gengliang Wang 9d0d4edb43 [SPARK-35595][TESTS] Support multiple loggers in testing method withLogAppender
### What changes were proposed in this pull request?

A test case of AdaptiveQueryExecSuite becomes flaky since there are too many debug logs in RootLogger:
https://github.com/Yikun/spark/runs/2715222392?check_suite_focus=true
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/139125/testReport/

To fix it,  I suggest supporting multiple loggers in the testing method withLogAppender. So that the LogAppender gets clean target log outputs.

### Why are the changes needed?

Fix a flaky test case.
Also, reduce unnecessary memory cost in tests.

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

Max Gekk a59063d544 [SPARK-35581][SQL] Support special datetime values in typed literals only
### What changes were proposed in this pull request?
In the PR, I propose to support special datetime values introduced by #25708 and by #25716 only in typed literals, and don't recognize them in parsing strings to dates/timestamps. The following string values are supported only in typed timestamp literals:
- `epoch [zoneId]` - `1970-01-01 00:00:00+00 (Unix system time zero)`
- `today [zoneId]` - midnight today.
- `yesterday [zoneId]` - midnight yesterday
- `tomorrow [zoneId]` - midnight tomorrow
- `now` - current query start time.

For example:
```sql
spark-sql> SELECT timestamp 'tomorrow';
2019-09-07 00:00:00
```

Similarly, the following special date values are supported only in typed date literals:
- `epoch [zoneId]` - `1970-01-01`
- `today [zoneId]` - the current date in the time zone specified by `spark.sql.session.timeZone`.
- `yesterday [zoneId]` - the current date -1
- `tomorrow [zoneId]` - the current date + 1
- `now` - the date of running the current query. It has the same notion as `today`.

For example:
```sql
spark-sql> SELECT date 'tomorrow' - date 'yesterday';
2
```

### Why are the changes needed?
In the current implementation, Spark supports the special date/timestamp value in any input strings casted to dates/timestamps that leads to the following problems:
- If executors have different system time, the result is inconsistent, and random. Column values depend on where the conversions were performed.
- The special values play the role of distributed non-deterministic functions though users might think of the values as constants.

### Does this PR introduce _any_ user-facing change?
Yes but the probability should be small.

### How was this patch tested?
By running existing test suites:
```
$ build/sbt "sql/testOnly org.apache.spark.sql.SQLQueryTestSuite -- -z interval.sql"
$ build/sbt "sql/testOnly org.apache.spark.sql.SQLQueryTestSuite -- -z date.sql"
$ build/sbt "sql/testOnly org.apache.spark.sql.SQLQueryTestSuite -- -z timestamp.sql"
$ build/sbt "test:testOnly *DateTimeUtilsSuite"
```

itholic 73d4f67145 [SPARK-35433][DOCS] Move CSV data source options from Python and Scala into a single page
### What changes were proposed in this pull request?

This PR proposes move CSV data source options from Python, Scala and Java into a single page.

### Why are the changes needed?

So far, the documentation for CSV data source options is separated into different pages for each language API documents. However, this makes managing many options inconvenient, so it is efficient to manage all options in a single page and provide a link to that page in the API of each language.

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

Yes, the documents will be shown below after this change:

Wenchen Fan bb2a0747d2 [SPARK-35578][SQL][TEST] Add a test case for a bug in janino
### What changes were proposed in this pull request?

This PR adds a unit test to show a bug in the latest janino version which fails to compile valid Java code. Unfortunately, I can't share the exact query that can trigger this bug (includes some custom expressions), but this pattern is not very uncommon and I believe can be triggered by some real queries.

A follow-up is needed before the 3.2 release, to either fix this bug in janino, or revert the janino version upgrade, or work around it in Spark.

### Why are the changes needed?

Gengliang Wang 8e11f5f007 [SPARK-35576][SQL] Redact the sensitive info in the result of Set command
### What changes were proposed in this pull request?

Currently, the results of following SQL queries are not redacted:
```
SET [KEY];
SET;
```
For example:

```
scala> spark.sql("set javax.jdo.option.ConnectionPassword=123456").show()
+--------------------+------+
|                 key| value|
+--------------------+------+
|javax.jdo.option....|123456|
+--------------------+------+

scala> spark.sql("set javax.jdo.option.ConnectionPassword").show()
+--------------------+------+
|                 key| value|
+--------------------+------+
|javax.jdo.option....|123456|
+--------------------+------+

scala> spark.sql("set").show()
+--------------------+--------------------+
|                 key|               value|
+--------------------+--------------------+
|javax.jdo.option....|              123456|

```

We should hide the sensitive information and redact the query output.

### Why are the changes needed?

Security.

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

Yes, the sensitive information in the output of Set commands are redacted

### How was this patch tested?

Unit test

shahid cd2ef9cb43 [SPARK-35567][SQL] Fix: Explain cost is not showing statistics for all the nodes
### What changes were proposed in this pull request?
Explain cost command in spark currently doesn't show statistics for all the nodes. It misses some nodes in almost all the TPCDS queries.
In this PR, we are collecting all the plan nodes including the subqueries and computing  the statistics for each node, if it doesn't exists in stats cache,

### Why are the changes needed?
**Before Fix**
For eg: Query1,  Project node doesn't have statistics

### What changes were proposed in this pull request?
Handle Currying Product while serializing TreeNode to JSON. While processing [Product](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/trees/TreeNode.scala#L820), we may get an assert error for cases like Currying Product because of the mismatch of sizes between field name and field values.

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

This pr add new rule to removes outer join if it only has distinct on streamed side. For example:
```scala
spark.range(200L).selectExpr("id AS a").createTempView("t1")
spark.range(300L).selectExpr("id AS b").createTempView("t2")
spark.sql("SELECT DISTINCT a FROM t1 LEFT JOIN t2 ON a = b").explain(true)
```

Before this pr:
```
== Optimized Logical Plan ==
Aggregate [a#2L], [a#2L]
+- Project [a#2L]
   +- Join LeftOuter, (a#2L = b#6L)
      :- Project [id#0L AS a#2L]
      :  +- Range (0, 200, step=1, splits=Some(2))
      +- Project [id#4L AS b#6L]
         +- Range (0, 300, step=1, splits=Some(2))
```

allisonwang-db 806da9d6fa [SPARK-35545][SQL] Split SubqueryExpression's children field into outer attributes and join conditions
### What changes were proposed in this pull request?
This PR refactors `SubqueryExpression` class. It removes the children field from SubqueryExpression's constructor and adds `outerAttrs` and `joinCond`.

### Why are the changes needed?
Currently, the children field of a subquery expression is used to store both collected outer references in the subquery plan and join conditions after correlated predicates are pulled up.

For example:
`SELECT (SELECT max(c1) FROM t1 WHERE t1.c1 = t2.c1) FROM t2`

During the analysis phase, outer references in the subquery are stored in the children field: `scalar-subquery [t2.c1]`, but after the optimizer rule `PullupCorrelatedPredicates`, the children field will be used to store the join conditions, which contain both the inner and the outer references: `scalar-subquery [t1.c1 = t2.c1]`. This is why the references of SubqueryExpression excludes the inner plan's output:
29ed1a2de4/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/subquery.scala (L68-L69)

This can be confusing and error-prone. The references for a subquery expression should always be defined as outer attribute references.

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

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

### What changes were proposed in this pull request?
After SPARK-29291 and SPARK-33352, there are still some compilation warnings about `procedure syntax is deprecated` as follows:

```
[WARNING] [Warn] /spark/core/src/main/scala/org/apache/spark/MapOutputTracker.scala:723: [deprecation   | origin= | version=2.13.0] procedure syntax is deprecated: instead, add `: Unit =` to explicitly declare `registerMergeResult`'s return type

dgd-contributor 52a1f8c000 [SPARK-33428][SQL] Match the behavior of conv function to MySQL's
### What changes were proposed in this pull request?
Spark conv function is from MySQL and it's better to follow the MySQL behavior. MySQL returns the max unsigned long if the input string is too big, and Spark should follow it.

However, seems Spark has different behavior in two cases:

MySQL allows leading spaces but Spark does not.
If the input string is way too long, Spark fails with ArrayIndexOutOfBoundException

This patch now help conv follow behavior in those two cases
conv allows leading spaces
conv will return the max unsigned long when the input string is way too long

### Why are the changes needed?

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

Add a new data source V2 API: `LocalScan`. It is a special Scan that will happen on Driver locally instead of Executors.

### Why are the changes needed?

The new API improves the flexibility of the DSV2 API. It allows developers to implement connectors for data sources of small data sizes.
For example, we can build a data source for Spark History applications from Spark History Server RESTFUL API. The result set is small and fetching all the results from the Spark driver is good enough. Making it a data source allows us to operate SQL queries with filters or table joins.

ulysses-you dc7b5a99f0 [SPARK-35282][SQL] Support AQE side shuffled hash join formula using rule
### What changes were proposed in this pull request?

The main code change is:
* Change rule `DemoteBroadcastHashJoin` to `DynamicJoinSelection` and add shuffle hash join selection code.
* Specify a join strategy hint `SHUFFLE_HASH` if AQE think a join can be converted to SHJ.
* Skip `preferSortMerge` config check in AQE side if a join can be converted to SHJ.

### Why are the changes needed?

Use AQE runtime statistics to decide if we can use shuffled hash join instead of sort merge join. Currently, the formula of shuffled hash join selection dose not work due to the dymanic shuffle partition number.

Add a new config spark.sql.adaptive.shuffledHashJoinLocalMapThreshold to decide if join can be converted to shuffled hash join safely.

Kousuke Saruta 50fefc6447 [SPARK-35527][SQL][TESTS] Fix HiveExternalCatalogVersionsSuite to pass with Java 11
### What changes were proposed in this pull request?

This PR fixes `HiveExternalCatalogVersionsSuite`.
With this change, only <major>.<minor> version is set to `spark.sql.hive.metastore.version`.

### Why are the changes needed?

I'm personally checking whether all the tests pass with Java 11 for the current `master` and I found `HiveExternalCatalogVersionsSuite` fails.
The reason is that Spark 3.0.2 and 3.1.1 doesn't accept `2.3.8` as a hive metastore version.

`HiveExternalCatalogVersionsSuite` downloads Spark releases from https://dist.apache.org/repos/dist/release/spark/ and run test for each release. The Spark releases are `3.0.2` and `3.1.1` for the current `master` for now.
e47e615c0e/sql/hive/src/test/scala/org/apache/spark/sql/hive/HiveExternalCatalogVersionsSuite.scala (L239-L259)

With Java 11, the suite run with a hive metastore version which corresponds to the builtin Hive version and it's `2.3.8` for the current `master`.
20750a3f9e/sql/hive/src/test/scala/org/apache/spark/sql/hive/HiveExternalCatalogVersionsSuite.scala (L62-L66)

But `branch-3.0` and `branch-3.1` doesn't accept `2.3.8`, the suite with Java 11 fails.

Another solution would be backporting SPARK-34271 (#31371) but after [a discussion](https://github.com/apache/spark/pull/32668#issuecomment-848435170), we prefer to fix the test,

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

No.

itholic 79a6b0cc8a [SPARK-35509][DOCS] Move text data source options from Python and Scala into a single page
### What changes were proposed in this pull request?

This PR proposes move text data source options from Python, Scala and Java into a single page.

### Why are the changes needed?

So far, the documentation for text data source options is separated into different pages for each language API documents. However, this makes managing many options inconvenient, so it is efficient to manage all options in a single page and provide a link to that page in the API of each language.

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

Yes, the documents will be shown below after this change:

Hyukjin Kwon 20750a3f9e [SPARK-32194][PYTHON] Use proper exception classes instead of plain Exception
### What changes were proposed in this pull request?

This PR proposes to use a proper built-in exceptions instead of the plain `Exception` in Python.

While I am here, I fixed another minor issue at `DataFrams.schema` together:

```diff
- except AttributeError as e:
-     raise Exception(
-         "Unable to parse datatype from schema. %s" % e)
+ except Exception as e:
+     raise ValueError(
+         "Unable to parse datatype from schema. %s" % e) from e
```

Now it catches all exceptions during schema parsing, chains the exception with `ValueError`. Previously it only caught `AttributeError` that does not catch all cases.

### Why are the changes needed?

For users to expect the proper exceptions.

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

Yeah, the exception classes became different but should be compatible because previous exception was plain `Exception` which other exceptions inherit.

### How was this patch tested?

Existing unittests should cover,

Wenchen Fan 859a53424a [SPARK-35447][SQL] Optimize skew join before coalescing shuffle partitions
### What changes were proposed in this pull request?

This PR improves the interaction between partition coalescing and skew handling by moving the skew join rule ahead of the partition coalescing rule and making corresponding changes to the two rules:
1. Simplify `OptimizeSkewedJoin` as it doesn't need to handle `CustomShuffleReaderExec` anymore.
2. Update `CoalesceShufflePartitions` to support coalescing non-skewed partitions.

### Why are the changes needed?

It's a bit hard to reason about skew join if partitions have been coalesced. A skewed partition needs to be much larger than other partitions and we need to look at the raw sizes before coalescing.

It also makes `OptimizeSkewedJoin` more robust, as we don't need to worry about a skewed partition being coalesced with a small partition and breaks skew join handling.

It also helps with https://github.com/apache/spark/pull/31653 , which needs to move `OptimizeSkewedJoin` to an earlier phase and run before `CoalesceShufflePartitions`.

Kousuke Saruta d4fb98354a [SPARK-35287][SQL] Allow RemoveRedundantProjects to preserve ProjectExec which generates UnsafeRow for DataSourceV2ScanRelation
### What changes were proposed in this pull request?

This PR fixes an issue that `RemoveRedundantProjects` removes `ProjectExec` which is for generating `UnsafeRow`.
In `DataSourceV2Strategy`, `ProjectExec` will be inserted to ensure internal rows are `UnsafeRow`.

```
  private def withProjectAndFilter(
      project: Seq[NamedExpression],
      filters: Seq[Expression],
      scan: LeafExecNode,
      needsUnsafeConversion: Boolean): SparkPlan = {
    val filterCondition = filters.reduceLeftOption(And)
    val withFilter = filterCondition.map(FilterExec(_, scan)).getOrElse(scan)

    if (withFilter.output != project || needsUnsafeConversion) {
      ProjectExec(project, withFilter)
    } else {
      withFilter
    }
  }
...
    case PhysicalOperation(project, filters, relation: DataSourceV2ScanRelation) =>
      // projection and filters were already pushed down in the optimizer.
      // this uses PhysicalOperation to get the projection and ensure that if the batch scan does
      // not support columnar, a projection is added to convert the rows to UnsafeRow.
      val batchExec = BatchScanExec(relation.output, relation.scan)
      withProjectAndFilter(project, filters, batchExec, !batchExec.supportsColumnar) :: Nil
```
So, the hierarchy of the partial tree should be like `ProjectExec(FilterExec(BatchScan))`.
But `RemoveRedundantProjects` doesn't consider this type of hierarchy, leading `ClassCastException`.

A concreate example to reproduce this issue is reported:

Adam Binford 6c0c617bd0 [SPARK-35449][SQL] Only extract common expressions from CaseWhen values if elseValue is set
### What changes were proposed in this pull request?

This PR fixes a bug with subexpression elimination for CaseWhen statements. https://github.com/apache/spark/pull/30245 added support for creating subexpressions that are present in all branches of conditional statements. However, for a statement to be in "all branches" of a CaseWhen statement, it must also be in the elseValue.

### Why are the changes needed?

Fix a bug where a subexpression can be created and run for branches of a conditional that don't pass. This can cause issues especially with a UDF in a branch that gets executed assuming the condition is true.

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

Yes, fixes a potential bug where a UDF could be eagerly executed even though it might expect to have already passed some form of validation. For example:
```
val col = when($"id" < 0, myUdf($"id"))
spark.range(1).select(when(col > 0, col)).show()
```

`myUdf($"id")` is considered a subexpression and eagerly evaluated, because it is pulled out as a common expression from both executions of the when clause, but if `id >= 0` it should never actually be run.

### How was this patch tested?

Updated existing test with new case.

Liang-Chi Hsieh 9e1b204bcc [SPARK-35410][SQL] SubExpr elimination should not include redundant children exprs in conditional expression
### What changes were proposed in this pull request?

This patch fixes a bug when dealing with common expressions in conditional expressions such as `CaseWhen` during subexpression elimination.

For example, previously we find common expressions among conditions of `CaseWhen`, but children expressions are also counted into. We should not count these children expressions as common expressions.

### Why are the changes needed?

If the redundant children expressions are counted as common expressions too, they will be redundantly evaluated and miss the subexpression elimination opportunity.

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

No

Hyukjin Kwon 1d9f09decb [SPARK-35480][SQL] Make percentile_approx work with pivot
### What changes were proposed in this pull request?

This PR proposes to avoid wrapping if-else to the constant literals for `percentage` and `accuracy` in `percentile_approx`. They are expected to be literals (or foldable expressions).

Pivot works by two phrase aggregations, and it works with manipulating the input to `null` for non-matched values (pivot column and value).

Note that pivot supports an optimized version without such logic with changing input to `null` for some types (non-nested types basically). So the issue fixed by this PR is only for complex types.

```scala
val df = Seq(
  ("a", -1.0), ("a", 5.5), ("a", 2.5), ("b", 3.0), ("b", 5.2)).toDF("type", "value")
  .groupBy().pivot("type", Seq("a", "b")).agg(
    percentile_approx(col("value"), array(lit(0.5)), lit(10000)))
df.show()
```

**Before:**

```
org.apache.spark.sql.AnalysisException: cannot resolve 'percentile_approx((IF((type <=> CAST('a' AS STRING)), value, CAST(NULL AS DOUBLE))), (IF((type <=> CAST('a' AS STRING)), array(0.5D), NULL)), (IF((type <=> CAST('a' AS STRING)), 10000, CAST(NULL AS INT))))' due to data type mismatch: The accuracy or percentage provided must be a constant literal;

**After:**

```

```

### Why are the changes needed?

Liang-Chi Hsieh 066944c1bd [SPARK-35439][SQL] Children subexpr should come first than parent subexpr
### What changes were proposed in this pull request?

This patch sorts equivalent expressions based on their child-parent relation.

### Why are the changes needed?

`EquivalentExpressions` maintains a map of equivalent expressions. It is `HashMap` now so the insertion order is not guaranteed to be preserved later. Subexpression elimination relies on retrieving subexpressions from the map. If there is child-parent relationships among the subexpressions, we want the child expressions come first than parent expressions, so we can replace child expressions in parent expressions with subexpression evaluation.

For example, we have two different expressions `Add(Literal(1), Literal(2))` and `Add(Literal(3), add)`.

Case 1: child subexpr comes first.
```scala
addExprTree(add)
addExprTree(Add(Literal(3), add))
addExprTree(Add(Literal(3), add))
```

Case 2: parent subexpr comes first. For this case, we need to sort equivalent expressions.
```
addExprTree(Add(Literal(3), add))  => We add `Add(Literal(3), add)` into the map first, then add `add` into the map
addExprTree(add)
addExprTree(Add(Literal(3), add))
```

As we are going to sort equivalent expressions at all, we don't need `LinkedHashMap` but just do sorting.

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

No

### How was this patch tested?

Added tests.
