### 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.
Fallback to use reflection to get all the values for constructor parameters when we meet such cases.
### Why are the changes needed?
Avoid throwing error while serializing TreeNode to JSON, try to output as much information as possible.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?

### 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))
```
After this pr:
```

This is a minor change to update how `StateStoreRestoreExec` computes its number of output rows. Previously we only count input rows, but the optionally restored rows are not counted in.
### Why are the changes needed?
Currently the number of output rows of `StateStoreRestoreExec` only counts the each input row. But it actually outputs input rows + optional restored rows. We should provide correct number of output rows.

### 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.

### 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

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.

### 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.

### 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,

### 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.

### 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`.

### 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`.

### What changes were proposed in this pull request?
Use `SpecificInternalRow` instead of `GenericInternalRow` to avoid boxing / unboxing cost.
### Why are the changes needed?
Since it doesn't know the input row schema, `GenericInternalRow` potentially need to apply boxing for input arguments. It's better to use `SpecificInternalRow` instead since we know input data types.

### 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.

### 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.

No

### 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;

### 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.

### What changes were proposed in this pull request?
Change the type of `DATASET_ID_TAG` from `Long` to `HashSet[Long]` to allow the logical plan to match multiple datasets.
### Why are the changes needed?
During the transformation from one Dataset to another Dataset, the DATASET_ID_TAG of logical plan won't change if the plan itself doesn't change:
b5241c97b1/sql/core/src/main/scala/org/apache/spark/sql/Dataset.scala (L234-L237)
However, dataset id always changes even if the logical plan doesn't change:
b5241c97b1/sql/core/src/main/scala/org/apache/spark/sql/Dataset.scala (L207-L208)
And this can lead to the mismatch between dataset's id and col's __dataset_id. E.g.,
```scala
test("SPARK-28344: fail ambiguous self join - Dataset.colRegex as column ref") {
// The test can fail if we change it to:
// val df1 = spark.range(3).toDF()
// val df2 = df1.filter($"id" > 0).toDF()
val df1 = spark.range(3)
val df2 = df1.filter($"id" > 0)
withSQLConf(
SQLConf.FAIL_AMBIGUOUS_SELF_JOIN_ENABLED.key -> "true",
SQLConf.CROSS_JOINS_ENABLED.key -> "true") {
assertAmbiguousSelfJoin(df1.join(df2, df1.colRegex("id") > df2.colRegex("id")))
}
}
```

### What changes were proposed in this pull request?
CTAS with location clause acts as an insert overwrite. This can cause problems when there are subdirectories within a location directory.
This causes some users to accidentally wipe out directories with very important data. We should not allow CTAS with location to a non-empty directory.
### Why are the changes needed?
Hive already handled this scenario: HIVE-11319
Steps to reproduce:
```scala
sql("""create external table `demo_CTAS`( `comment` string) PARTITIONED BY (`col1` string, `col2` string) STORED AS parquet location '/tmp/u1/demo_CTAS'""")
sql("""INSERT OVERWRITE TABLE demo_CTAS partition (col1='1',col2='1') VALUES ('abc')""")
sql("select* from demo_CTAS").show
sql("""create table ctas1 location '/tmp/u2/ctas1' as select * from demo_CTAS""")
sql("select* from ctas1").show
sql("""create table ctas2 location '/tmp/u2' as select * from demo_CTAS""")
```
Before the fix: Both create table operations will succeed. But values in table ctas1 will be replaced by ctas2 accidentally.
After the fix: `create table ctas2...` will throw `AnalysisException`:
```
org.apache.spark.sql.AnalysisException: CREATE-TABLE-AS-SELECT cannot create table with location to a non-empty directory /tmp/u2 . To allow overwriting the existing non-empty directory, set 'spark.sql.legacy.allowNonEmptyLocationInCTAS' to true.
```
### Does this PR introduce _any_ user-facing change?
Yes, if the location directory is not empty, CTAS with location will throw AnalysisException
```
sql("""create table ctas2 location '/tmp/u2' as select * from demo_CTAS""")
```
```
org.apache.spark.sql.AnalysisException: CREATE-TABLE-AS-SELECT cannot create table with location to a non-empty directory /tmp/u2 . To allow overwriting the existing non-empty directory, set 'spark.sql.legacy.allowNonEmptyLocationInCTAS' to true.
```
`CREATE TABLE AS SELECT` with non-empty `LOCATION` will throw `AnalysisException`. To restore the behavior before Spark 3.2, need to set `spark.sql.legacy.allowNonEmptyLocationInCTAS` to `true`. , default value is `false`.
Updated SQL migration guide.

### What changes were proposed in this pull request?
AQE has an optimization where it attempts to reuse compatible exchanges but it does not take into account whether the exchanges are columnar or not, resulting in incorrect reuse under some circumstances.
This PR simply changes the key used to lookup cached stages. It now uses the canonicalized form of the new query stage (potentially created by a plugin) rather than using the canonicalized form of the original exchange.
### Why are the changes needed?
When using the [RAPIDS Accelerator for Apache Spark](https://github.com/NVIDIA/spark-rapids) we sometimes see a new query stage correctly create a row-based exchange and then Spark replaces it with a cached columnar exchange, which is not compatible, and this causes queries to fail.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
The patch has been tested with the query that highlighted this issue. I looked at writing unit tests for this but it would involve implementing a mock columnar exchange in the tests so would be quite a bit of work. If anyone has ideas on other ways to test this I am happy to hear them.

### What changes were proposed in this pull request?
1. In HadoopMapReduceCommitProtocol, create parent directory before renaming custom partition path staging files
2. In InMemoryCatalog and HiveExternalCatalog, create new partition directory before renaming old partition path
3. Check return value of FileSystem#rename, if false, throw exception to avoid silent data loss cause by rename failure
4. Change DebugFilesystem#rename behavior to make it match HDFS's behavior (return false without rename when dst parent directory not exist)
### Why are the changes needed?
Depends on FileSystem#rename implementation, when destination directory does not exist, file system may
1. return false without renaming file nor throwing exception (e.g. HDFS), or
2. create destination directory, rename files, and return true (e.g. LocalFileSystem)
In the first case above, renames in HadoopMapReduceCommitProtocol for custom partition path will fail silently if the destination partition path does not exist. Failed renames can happen when
1. dynamicPartitionOverwrite == true, the custom partition path directories are deleted by the job before the rename; or
2. the custom partition path directories do not exist before the job; or
3. something else is wrong when file system handle `rename`
The renames in MemoryCatalog and HiveExternalCatalog for partition renaming also have similar issue.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Modified DebugFilesystem#rename, and added new unit tests.

### What changes were proposed in this pull request?
SPARK-35253 upgraded janino from 3.0.16 to 3.1.4, `ClassBodyEvaluator` provides the `getBytecodes` method to get
the mapping from `ClassFile#getThisClassName` to `ClassFile#toByteArray` directly in this version and we don't need to get this variable by reflection api anymore.
So the main purpose of this pr is simplify the way to get `bytecodes` from `ClassBodyEvaluator` in `CodeGenerator#updateAndGetCompilationStats` method.
### Why are the changes needed?
Code simplification.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
- Pass the Jenkins or GitHub Action
- Manual test:
1. Define a code fragment to be tested, for example:
```
val codeBody = s"""
public java.lang.Object generate(Object[] references) {
return new TestMetricCode(references);
}
class TestMetricCode {
public TestMetricCode(Object[] references) {
}
public long sumOfSquares(long left, long right) {
return left * left + right * right;
}
}
"""
```
2. Create a `ClassBodyEvaluator` and `cook` the `codeBody` as above, the process of creating `ClassBodyEvaluator` can extract from `CodeGenerator#doCompile` method.
3. Get `bytecodes` using `ClassBodyEvaluator#getBytecodes` api(after this pr) and reflection api(before this pr) respectively, then assert that they are the same. If the `bytecodes` not changed, we can be sure that metrics state will not change. The test code example as follows:
```
import scala.collection.JavaConverters._
val bytecodesFromApi = evaluator.getBytecodes.asScala
val bytecodesFromReflectionApi = {
val scField = classOf[ClassBodyEvaluator].getDeclaredField("sc")
scField.setAccessible(true)
val compiler = scField.get(evaluator).asInstanceOf[SimpleCompiler]
val loader = compiler.getClassLoader.asInstanceOf[ByteArrayClassLoader]
val classesField = loader.getClass.getDeclaredField("classes")

### What changes were proposed in this pull request?
Write out Seq of product objects which contain TreeNode, to avoid the cases as described in https://issues.apache.org/jira/browse/SPARK-35411 that essential information will be ignored and just written out as null values. These information are necessary to understand the query plans.
### Why are the changes needed?

### What changes were proposed in this pull request?
To pass the TPCDS-related plan stability tests in scala-2.13, this PR proposes to fix two things below;
- (1) Sorts elements in the predicate `InSet` and the source filter `In` for printing their nodes.
- (2) Formats nested collection elements (`Seq`, `Array`, and `Set`) recursively in `TreeNode.argString`.
As for (1), it seems v2.12/v2.13 prints `Set` elements with a different order, so we need to sort them explicitly. As for (2), the `Seq` implementation is different between v2.12/v2.13, so we need to format nested `Seq` elements correctly to hide the name of its implementation (See an example below);

### What changes were proposed in this pull request?
When creating `Invoke` and `StaticInvoke` for `ScalarFunction`'s magic method, set `propagateNull` to false.
### Why are the changes needed?
When `propgagateNull` is true (which is the default value), `Invoke` and `StaticInvoke` will return null if any of the argument is null. For scalar function this is incorrect, as we should leave the logic to function implementation instead.
### Does this PR introduce _any_ user-facing change?
Yes. Now null arguments shall be properly handled with magic method.

### What changes were proposed in this pull request?
Fix test failure under Scala 2.13 by making test `ScalaFunction` `StrLenMagic` public.
### Why are the changes needed?
A few tests are failing when using Scala 2.13 with error message like the following:
```
[info] Cause: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 35, Column 121: failed to compile: org.codehaus.commons.compiler.CompileException: File 'generated.java', Line 35, Column 121: No a

[info] at org.apache.spark.sql.catalyst.expressions.codegen.CodeGenerator$$anon$1.load(CodeGenerator.scala:1501)
```
This seems to be caused by the fact that the `StrLenMagic` is using `private` scope. After removing the `private` keyword the tests are now passing.

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 UpdatingSessionsIterator, which analyzes neighbor elements and adjust session information on elements.
UpdatingSessionsIterator calculates and updates the session window for each element in the given iterator, which makes elements in the same session window having same session spec. Downstream can apply aggregation to finally merge these elements bound to the same session window.
UpdatingSessionsIterator works on the precondition that given iterator is sorted by "group keys + start time of session window", and the iterator still retains the characteristic of the sort.
UpdatingSessionsIterator copies the elements to safely update on each element, as well as buffers elements which are bound to the same session window. Due to such overheads, MergingSessionsIterator which will be introduced via SPARK-34889 should be used whenever possible.
This PR also introduces UpdatingSessionsExec which is the physical node on leveraging UpdatingSessionsIterator to sort the input rows and updates session information on input rows.

Here is an extract from IEEE 754:
> The two zeros are distinguishable arithmetically only by either division-byzero ( producing appropriately signed infinities ) or else by the CopySign function recommended by IEEE 754 /854. Infinities, SNaNs, NaNs and Subnormal numbers necessitate four more special cases
From this, I deduce that the hash function must produce the same result for 0 and -0.

### What changes were proposed in this pull request?
Add New SQL functions:
* TRY_ADD
* TRY_DIVIDE
These expressions are identical to the following expression under ANSI mode except that it returns null if error occurs:
* ADD
* DIVIDE
Note: it is easy to add other expressions like `TRY_SUBTRACT`/`TRY_MULTIPLY` but let's control the number of these new expressions and just add `TRY_ADD` and `TRY_DIVIDE` for now.
### Why are the changes needed?
1. Users can manage to finish queries without interruptions in ANSI mode.
2. Users can get NULLs instead of unreasonable results if overflow occurs when ANSI mode is off.
For example, the behavior of the following SQL operations is unreasonable:
```
2147483647 + 2 => -2147483647
```
With the new safe version SQL functions:
```
TRY_ADD(2147483647, 2) => null
```
Note: **We should only add new expressions to important operators, instead of adding new safe expressions for all the expressions that can throw errors.**

### What changes were proposed in this pull request?
In Spark, we have an extension in the MERGE syntax: INSERT/UPDATE *. This is not from ANSI standard or any other mainstream databases, so we need to define the behaviors by our own.
The behavior today is very weird: assume the source table has `n1` columns, target table has `n2` columns. We generate the assignments by taking the first `min(n1, n2)` columns from source & target tables and pairing them by ordinal.
This PR proposes a more reasonable behavior: take all the columns from target table as keys, and find the corresponding columns from source table by name as values.
### Why are the changes needed?
Fix the MEREG INSERT/UPDATE * to be more user-friendly and easy to do schema evolution.
### Does this PR introduce _any_ user-facing change?
Yes, but MERGE is only supported by very few data sources.
### How was this patch tested?

### What changes were proposed in this pull request?
In https://github.com/yaooqinn/itachi/issues/8, we had a discussion about the current extension injection for the spark session. We've agreed that the current way is not that convenient for both third-party developers and end-users.
It's much simple if third-party developers can provide a resource file that contains default extensions for Spark to load ahead

### What changes were proposed in this pull request?
Change `map` in `InvokeLike.invoke` to a while loop to improve performance, following Spark [style guide](https://github.com/databricks/scala-style-guide#traversal-and-zipwithindex).
### Why are the changes needed?
`InvokeLike.invoke`, which is used in non-codegen path for `Invoke` and `StaticInvoke`, currently uses `map` to evaluate arguments:
```scala
val args = arguments.map(e => e.eval(input).asInstanceOf[Object])
if (needNullCheck && args.exists(_ == null)) {
// return null if one of arguments is null
null
} else {
...
```
which is pretty expensive if the method itself is trivial. We can change it to a plain while loop.

### What changes were proposed in this pull request?
This PR proposes to bump up the janino version from 3.0.16 to v3.1.4.
The major changes of this upgrade are as follows:
- Fixed issue #131: Janino 3.1.2 is 10x slower than 3.0.11: The Compiler's IClassLoader was initialized way too eagerly, thus lots of classes were loaded from the class path, which is very slow.
- Improved the encoding of stack map frames according to JVMS11 4.7.4: Previously, only "full_frame"s were generated.
- Fixed issue #107: Janino requires "org.codehaus.commons.compiler.io", but commons-compiler does not export this package
- Fixed the promotion of the array access index expression (see JLS7 15.13 Array Access Expressions).
For all the changes, please see the change log: http://janino-compiler.github.io/janino/changelog.html
NOTE1: I've checked that there is no obvious performance regression. For all the data, see a link: https://docs.google.com/spreadsheets/d/1srxT9CioGQg1fLKM3Uo8z1sTzgCsMj4pg6JzpdcG6VU/edit?usp=sharing
NOTE2: We upgraded janino to 3.1.2 (#27860) once before, but the commit had been reverted in #29495 because of the correctness issue. Recently, #32374 had checked if Spark could land on v3.1.3 or not, but a new bug was found there. These known issues has been fixed in v3.1.4 by following PRs:
- janino-compiler/janino#145
- janino-compiler/janino#146
### Why are the changes needed?
janino v3.0.X is no longer maintained.

### What changes were proposed in this pull request?
In `ApplyFunctionExpression`, move `zipWithIndex` out of the loop for each input row.

When the `ScalarFunction` is trivial, `zipWithIndex` could incur significant costs, as shown below:

By removing it out of the loop, I'm seeing sometimes 2x speedup from `V2FunctionBenchmark`. For instance:

### What changes were proposed in this pull request?
This PR proposes to filter out TPCDS v1.4 q6 and q75 in `TPCDSQueryTestSuite`.
I saw`TPCDSQueryTestSuite` failed nondeterministically because output row orders were different with those in the golden files. For example, the failure in the GA job, https://github.com/linhongliu-db/spark/runs/2507928605?check_suite_focus=true, happened because the `tpcds/q6.sql` query output rows were only sorted by `cnt`:
a0c76a8755/sql/core/src/test/resources/tpcds/q6.sql (L20)
Actually, `tpcds/q6.sql` and `tpcds-v2.7.0/q6.sql` are almost the same and the only difference is that `tpcds-v2.7.0/q6.sql` sorts both `cnt` and `a.ca_state`:
a0c76a8755/sql/core/src/test/resources/tpcds-v2.7.0/q6.sql (L22)
So, I think it's okay just to test `tpcds-v2.7.0/q6.sql` in this case (q75 has the same issue).

### What changes were proposed in this pull request?
This allows `ScalarFunction` implemented in Java to optionally specify the magic method `invoke` to be static, which can be used if the UDF is stateless. Comparing to the non-static method, it can potentially give better performance due to elimination of dynamic dispatch, etc.
Also added a benchmark to measure performance of: the default `produceResult`, non-static magic method and static magic method.
### Why are the changes needed?
For UDFs that are stateless (e.g., no need to maintain intermediate state between each function call), it's better to allow users to implement the UDF function as static method which could potentially give better performance.
### Does this PR introduce _any_ user-facing change?
Yes. Spark users can now have the choice to define static magic method for `ScalarFunction` when it is written in Java and when the UDF is stateless.

### What changes were proposed in this pull request?
Instantiate a new Hive client through `Hive.getWithFastCheck(conf, false)` instead of `Hive.get(conf)`.
### 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`.
### 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 (with HIVE-24608 too)
### How was this patch tested?
Manually started a HMS server of Hive version 1.2.2, with patched Hive 2.3.8 using HIVE-24608. 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.

### What changes were proposed in this pull request?
This patch proposes to make StaticInvoke able to find method with given method name even the parameter types do not exactly match to argument classes.
### Why are the changes needed?
Unlike `Invoke`, `StaticInvoke` only tries to get the method with exact argument classes. If the calling method's parameter types are not exactly matched with the argument classes, `StaticInvoke` cannot find the method.
`StaticInvoke` should be able to find the method under the cases too.
### Does this PR introduce _any_ user-facing change?

This is a follow up to https://github.com/apache/spark/pull/32032#discussion_r620928086. Basically, `children`/`innerChildren` should be mutually exclusive for `AlterViewAsCommand` and `CreateViewCommand`, which extend `AnalysisOnlyCommand`. Otherwise, there could be an issue in the `EXPLAIN` command. Currently, this is not an issue, because these commands will be analyzed (children will always be empty) when the `EXPLAIN` command is run.
### Why are the changes needed?

### What changes were proposed in this pull request?
`EXPLAIN CODEGEN <query>` (and Dataset.explain("codegen")) prints out the generated code for each stage of plan. The current implementation is to match `WholeStageCodegenExec` operator in query plan and prints out generated code (https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/debug/package.scala#L111-L118 ). This does not work with AQE as we wrap the whole query plan inside `AdaptiveSparkPlanExec` and do not run whole stage code-gen physical plan rule eagerly (`CollapseCodegenStages`). This introduces unexpected behavior change for EXPLAIN query (and Dataset.explain), as we enable AQE by default now.
The change is to explain code-gen for the current executed plan of AQE.
### Why are the changes needed?
Make `EXPLAIN CODEGEN` work same as before.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
This patch changes a few places using `FileSystem` API to manipulate checkpoint file to `CheckpointFileManager`.
### Why are the changes needed?
`CheckpointFileManager` is designed to handle checkpoint file manipulation. However, there are a few places exposing `FileSystem` from checkpoint files/paths. We should use `CheckpointFileManager` to manipulate checkpoint files. For example, we may want to have one storage system for checkpoint file. If all checkpoint file manipulation is performed through `CheckpointFileManager`, we can only implement `CheckpointFileManager` for the storage system, and don't need to implement `FileSystem` API for it.

### What changes were proposed in this pull request?
This pull request proposes a new API for streaming sources to signal that they can report metrics, and adds a use case to support Kafka micro batch stream to report the stats of # of offsets for the current offset falling behind the latest.
A public interface is added.
`metrics`: returns the metrics reported by the streaming source with given offset.
### Why are the changes needed?
The new API can expose any custom metrics for the "current" offset for streaming sources. Different from #31398, this PR makes metrics available to user through progress report, not through spark UI. A use case is that people want to know how the current offset falls behind the latest offset.

### What changes were proposed in this pull request?
To fix lambda variable name issues in nested DataFrame functions, this PR modifies code to use a global counter for `LambdaVariables` names created by higher order functions.
This is the rework of #31887. Closes#31887.
### Why are the changes needed?
This moves away from the current hard-coded variable names which break on nested function calls. There is currently a bug where nested transforms in particular fail (the inner variable shadows the outer variable)
For this query:
```
val df = Seq(
(Seq(1,2,3), Seq("a", "b", "c"))
).toDF("numbers", "letters")
df.select(
f.flatten(
f.transform(
$"numbers",
(number: Column) => { f.transform(
$"letters",
(letter: Column) => { f.struct(
number.as("number"),
letter.as("letter")
) }
) }
)
).as("zipped")
).show(10, false)
```
This is the current (incorrect) output:
```
+------------------------------------------------------------------------+
|zipped |
+------------------------------------------------------------------------+
|[{a, a}, {b, b}, {c, c}, {a, a}, {b, b}, {c, c}, {a, a}, {b, b}, {c, c}]|
+------------------------------------------------------------------------+
```
And this is the correct output after fix:
```
+------------------------------------------------------------------------+
|zipped |
+------------------------------------------------------------------------+
|[{1, a}, {1, b}, {1, c}, {2, a}, {2, b}, {2, c}, {3, a}, {3, b}, {3, c}]|
+------------------------------------------------------------------------+
```

### What changes were proposed in this pull request?
1. Extend Spark SQL parser to support parsing of:
- `INTERVAL YEAR TO MONTH` to `YearMonthIntervalType`
- `INTERVAL DAY TO SECOND` to `DayTimeIntervalType`
2. Assign new names to the ANSI interval types according to the SQL standard to be able to parse the names back by Spark SQL parser. Override the `typeName()` name of `YearMonthIntervalType`/`DayTimeIntervalType`.
### Why are the changes needed?
To be able to use new ANSI interval types in SQL. The SQL standard requires the types to be defined according to the rules:
```
<interval type> ::= INTERVAL <interval qualifier>
<interval qualifier> ::= <start field> TO <end field> | <single datetime field>
<start field> ::= <non-second primary datetime field> [ <left paren> <interval leading field precision> <right paren> ]
<end field> ::= <non-second primary datetime field> | SECOND [ <left paren> <interval fractional seconds precision> <right paren> ]
<primary datetime field> ::= <non-second primary datetime field | SECOND
<non-second primary datetime field> ::= YEAR | MONTH | DAY | HOUR | MINUTE
<interval fractional seconds precision> ::= <unsigned integer>
<interval leading field precision> ::= <unsigned integer>
```
Currently, Spark SQL supports only `YEAR TO MONTH` and `DAY TO SECOND` as `<interval qualifier>`.
### Does this PR introduce _any_ user-facing change?
Should not since the types has not been released yet.
### How was this patch tested?
By running the affected tests such as:
```
$ build/sbt "sql/testOnly *SQLQueryTestSuite -- -z interval.sql"
$ build/sbt "sql/testOnly *SQLQueryTestSuite -- -z datetime.sql"
$ build/sbt "test:testOnly *ExpressionTypeCheckingSuite"

### What changes were proposed in this pull request?
This PR proposes to port minimal code to generate TPC-DS data from [databricks/spark-sql-perf](https://github.com/databricks/spark-sql-perf). The classes in a new class file `tpcdsDatagen.scala` are basically copied from the `databricks/spark-sql-perf` codebase.
Note that I've modified them a bit to follow the Spark code style and removed unnecessary parts from them.
The code authors of these classes are:
juliuszsompolski
npoggi
wangyum
### Why are the changes needed?
We frequently use TPCDS data now for benchmarks/tests, but the classes for the TPCDS schemas of datagen and benchmarks/tests are managed separately, e.g.,
- https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/TPCDSBase.scala
- https://github.com/databricks/spark-sql-perf/blob/master/src/main/scala/com/databricks/spark/sql/perf/tpcds/TPCDSTables.scala
I think this causes some inconveniences, e.g., we need to update both files in the separate repositories if we update the TPCDS schema #32037. So, it would be useful for the Spark codebase to generate them by referring to the same schema definition.

### What changes were proposed in this pull request?
This PR adds a new rule `PullOutGroupingExpressions` to pull out complex grouping expressions to a `Project` node under an `Aggregate`. These expressions are then referenced in both grouping expressions and aggregate expressions without aggregate functions to ensure that optimization rules don't change the aggregate expressions to invalid ones that no longer refer to any grouping expressions.
### Why are the changes needed?
If aggregate expressions (without aggregate functions) in an `Aggregate` node are complex then the `Optimizer` can optimize out grouping expressions from them and so making aggregate expressions invalid.
Here is a simple example:
```
SELECT not(t.id IS NULL) , count(*)
FROM t
GROUP BY t.id IS NULL
```
In this case the `BooleanSimplification` rule does this:
```
=== Applying Rule org.apache.spark.sql.catalyst.optimizer.BooleanSimplification ===
!Aggregate [isnull(id#222)], [NOT isnull(id#222) AS (NOT (id IS NULL))#226, count(1) AS c#224L] Aggregate [isnull(id#222)], [isnotnull(id#222) AS (NOT (id IS NULL))#226, count(1) AS c#224L]
+- Project [value#219 AS id#222] +- Project [value#219 AS id#222]
+- LocalRelation [value#219] +- LocalRelation [value#219]
```
where `NOT isnull(id#222)` is optimized to `isnotnull(id#222)` and so it no longer refers to any grouping expression.
Before this PR:
```
== Optimized Logical Plan ==
Aggregate [isnull(id#222)], [isnotnull(id#222) AS (NOT (id IS NULL))#234, count(1) AS c#232L]
+- Project [value#219 AS id#222]
+- LocalRelation [value#219]
```
and running the query throws an error:
```
Couldn't find id#222 in [isnull(id#222)#230,count(1)#226L]
java.lang.IllegalStateException: Couldn't find id#222 in [isnull(id#222)#230,count(1)#226L]
```
After this PR:
```
== Optimized Logical Plan ==
Aggregate [_groupingexpression#233], [NOT _groupingexpression#233 AS (NOT (id IS NULL))#230, count(1) AS c#228L]
+- Project [isnull(value#219) AS _groupingexpression#233]
+- LocalRelation [value#219]
```
and the query works.

### What changes were proposed in this pull request?
~~This PR aims to add a new AQE optimizer rule `DynamicJoinSelection`. Like other AQE partition number configs, this rule add a new broadcast threshold config `spark.sql.adaptive.autoBroadcastJoinThreshold`.~~
This PR amis to add a flag in `Statistics` to distinguish AQE stats or normal stats, so that we can make some sql configs isolation between AQE and normal.
### Why are the changes needed?
The main idea here is that make join config isolation between normal planner and aqe planner which shared the same code path.
Actually we do not very trust using the static stats to consider if it can build broadcast hash join. In our experience it's very common that Spark throw broadcast timeout or driver side OOM exception when execute a bit large plan. And due to braodcast join is not reversed which means if we covert join to braodcast hash join at first time, we(AQE) can not optimize it again, so it should make sense to decide if we can do broadcast at aqe side using different sql config.
### Does this PR introduce _any_ user-facing change?
Yes, a new config `spark.sql.adaptive.autoBroadcastJoinThreshold` added.

To enable/disable this feature, I introduce a new option `writeNonAsciiCharacterAsCodePoint` for JSON datasources.
### Why are the changes needed?
JSON specification allows codepoints as literal but Spark SQL's JSON datasources don't support the way to do it.
It's great if we can write non-ascii characters as codepoints, which is a platform neutral representation.
### Does this PR introduce _any_ user-facing change?
Yes. Users can write non-ascii characters as codepoints with JSON datasources.
### How was this patch tested?
New test.

### What changes were proposed in this pull request?
This PR extends `ADD FILE/JAR/ARCHIVE` commands to be able to take multiple path arguments like Hive.
### Why are the changes needed?
To make those commands more useful.
### Does this PR introduce _any_ user-facing change?
Yes. In the current implementation, those commands can take a path which contains whitespaces without enclose it by neither `'` nor `"` but after this change, users need to enclose such paths.
I've note this incompatibility in the migration guide.

### What changes were proposed in this pull request?
This PR proposes to introduce a new JDBC option `refreshKrb5Config` which allows to reflect the change of `krb5.conf`.
### Why are the changes needed?
In the current master, JDBC datasources can't accept `refreshKrb5Config` which is defined in `Krb5LoginModule`.
So even if we change the `krb5.conf` after establishing a connection, the change will not be reflected.
The similar issue happens when we run multiple `*KrbIntegrationSuites` at the same time.
`MiniKDC` starts and stops every KerberosIntegrationSuite and different port number is recorded to `krb5.conf`.
Due to `SecureConnectionProvider.JDBCConfiguration` doesn't take `refreshKrb5Config`, KerberosIntegrationSuites except the first running one see the wrong port so those suites fail.
You can easily confirm with the following command.
```
build/sbt -Phive Phive-thriftserver -Pdocker-integration-tests "testOnly org.apache.spark.sql.jdbc.*KrbIntegrationSuite"
```
### Does this PR introduce _any_ user-facing change?
Yes. Users can set `refreshKrb5Config` to refresh krb5 relevant configuration.

### What changes were proposed in this pull request?
This implements function resolution and evaluation for functions registered through V2 FunctionCatalog [SPARK-27658](https://issues.apache.org/jira/browse/SPARK-27658). In particular:
- Added documentation for how to define the "magic method" in `ScalarFunction`.
- Added a new expression `ApplyFunctionExpression` which evaluates input by delegating to `ScalarFunction.produceResult` method.
- added a new expression `V2Aggregator` which is a type of `TypedImperativeAggregate`. It's a wrapper of V2 `AggregateFunction` and mostly delegate methods to the implementation of the latter. It also uses plain Java serde for intermediate state.
- Added function resolution logic for `ScalarFunction` and `AggregateFunction` in `Analyzer`.
+ For `ScalarFunction` this checks if the magic method is implemented through Java reflection, and create a `Invoke` expression if so. Otherwise, it checks if the default `produceResult` is overridden. If so, it creates a `ApplyFunctionExpression` which evaluates through `InternalRow`. Otherwise an analysis exception is thrown.
+ For `AggregateFunction`, this checks if the `update` method is overridden. If so, it converts it to `V2Aggregator`. Otherwise an analysis exception is thrown similar to the case of `ScalarFunction`.
- Extended existing `InMemoryTableCatalog` to add the function catalog capability. Also renamed it to `InMemoryCatalog` since it no longer only covers tables.
**Note**: this currently can successfully detect whether a subclass overrides the default `produceResult` or `update` method from the parent interface **only for Java implementations**. It seems in Scala it's hard to differentiate whether a subclass overrides a default method from its parent interface. In this case, it will be a runtime error instead of analysis error.
A few TODOs:
- Extend `V2SessionCatalog` with function catalog. This seems a little tricky since API such V2 `FunctionCatalog`'s `loadFunction` is different from V1 `SessionCatalog`'s `lookupFunction`.
- Add magic method for `AggregateFunction`.
- Type coercion when looking up functions
### Why are the changes needed?
As V2 FunctionCatalog APIs are finalized, we should integrate it with function resolution and evaluation process so that they are actually useful.
### Does this PR introduce _any_ user-facing change?
Yes, now a function exposed through V2 FunctionCatalog can be analyzed and evaluated.
### How was this patch tested?
Added new unit tests.

### What changes were proposed in this pull request?
In this PR, we add extract/date_part support for ANSI Intervals
The `extract` is an ANSI expression and `date_part` is NON-ANSI but exists as an equivalence for `extract`
#### expression
```
<extract expression> ::=
EXTRACT <left paren> <extract field> FROM <extract source> <right paren>
```
#### <extract field> for interval source
```
<primary datetime field> ::=
<non-second primary datetime field>
| SECOND
<non-second primary datetime field> ::=
YEAR
| MONTH
| DAY
| HOUR
| MINUTE
```
#### dataType
```
If <extract field> is a <primary datetime field> that does not specify SECOND or <extract field> is not a <primary datetime field>, then the declared type of the result is an implementation-defined exact numeric type with scale 0 (zero)
Otherwise, the declared type of the result is an implementation-defined exact numeric type with scale not less than the specified or implied <time fractional seconds precision> or <interval fractional seconds precision>, as appropriate, of the SECOND <primary datetime field> of the <extract source>.
```
### Why are the changes needed?

### What changes were proposed in this pull request?
This is a re-proposal of https://github.com/apache/spark/pull/23163. Currently spark always requires a [local sort](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/FileFormatWriter.scala#L188) before writing to output table with dynamic partition/bucket columns. The sort can be unnecessary if cardinality of partition/bucket values is small, and can be avoided by keeping multiple output writers concurrently.
This PR introduces a config `spark.sql.maxConcurrentOutputFileWriters` (which disables this feature by default), where user can tune the maximal number of concurrent writers. The config is needed here as we cannot keep arbitrary number of writers in task memory which can cause OOM (especially for Parquet/ORC vectorization writer).
The feature is to first use concurrent writers to write rows. If the number of writers exceeds the above config specified limit. Sort rest of rows and write rows one by one (See `DynamicPartitionDataConcurrentWriter.writeWithIterator()`).
In addition, interface `WriteTaskStatsTracker` and its implementation `BasicWriteTaskStatsTracker` are also changed because previously they are relying on the assumption that only one writer is active for writing dynamic partitions and bucketed table.
### Why are the changes needed?
Avoid the sort before writing output for dynamic partitioned query and bucketed table.
Help improve CPU and IO performance for these queries.
### Does this PR introduce _any_ user-facing change?
No.

### What changes were proposed in this pull request?
This is another attempt to fix the flaky test "query without test harness" on ContinuousSuite.
`query without test harness` is flaky because it starts a continuous query with two partitions but assumes they will run at the same speed.
In this test, 0 and 2 will be written to partition 0, 1 and 3 will be written to partition 1. It assumes when we see 3, 2 should be written to the memory sink. But this is not guaranteed. We can add `if (currentValue == 2) Thread.sleep(5000)` at this line b2a2b5d820/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/continuous/ContinuousRateStreamSource.scala (L135) to reproduce the failure: `Result set Set([0], [1], [3]) are not a superset of Set(0, 1, 2, 3)!`
The fix is changing `waitForRateSourceCommittedValue` to wait until all partitions reach the desired values before stopping the query.

### What changes were proposed in this pull request?
This patch proposes an improvement on nested column pruning if the pruning target is generator's output. Previously we disallow such case. This patch allows to prune on it if there is only one single nested column is accessed after `Generate`.
E.g., `df.select(explode($"items").as('item)).select($"item.itemId")`. As we only need `itemId` from `item`, we can prune other fields out and only keep `itemId`.
In this patch, we only address explode-like generators. We will address other generators in followups.

### What changes were proposed in this pull request?
Modifies the UpdateFields optimizer to fix correctness issues with certain nested and chained withField operations. Examples for recreating the issue are in the new unit tests as well as the JIRA issue.
### Why are the changes needed?
Certain withField patterns can cause Exceptions or even incorrect results. It appears to be a result of the additional UpdateFields optimization added in https://github.com/apache/spark/pull/29812. It traverses fieldOps in reverse order to take the last one per field, but this can cause nested structs to change order which leads to mismatches between the schema and the actual data. This updates the optimization to maintain the initial ordering of nested structs to match the generated schema.
### Does this PR introduce _any_ user-facing change?
It fixes exceptions and incorrect results for valid uses in the latest Spark release.
### How was this patch tested?
Added new unit tests for these edge cases.

DayTimeIntervalType/YearMonthIntervalString show different between Hive SerDe and row format delimited.
Create this pr to add a test and have disscuss.
For this problem I think we have two direction:
1. leave it as current and add a item t explain this in migration guide docs.
2. Since we should not change hive serde's behavior, so we can cast spark row format delimited's behavior to use cast DayTimeIntervalType/YearMonthIntervalType as HIVE_STYLE

### What changes were proposed in this pull request?
This patch proposes to add a couple of metrics in scan node for Kafka batch streaming query.
### Why are the changes needed?
When testing SS, I found it is hard to track data loss of SS reading from Kafka. The micro batch scan node has only one metric, number of output rows. Users have no idea how many offsets to fetch are out of Kafka, how many times data loss happens. These metrics are important for users to know the quality of SS query running.
### Does this PR introduce _any_ user-facing change?
Yes, adding two metrics to micro batch scan node for Kafka batch streaming.
### How was this patch tested?
Currently I tested on internal cluster with Kafka:

I was trying to add unit test. But as our batch streaming query disallows to specify ending offsets. If I only specify an out-of-range starting offset, when we get offset range in `getRanges`, any negative size range will be filtered out. So it cannot actually test the case of fetched non-existing offset.

### What changes were proposed in this pull request?
For partial hash aggregation (code-gen path), we have two level of hash map for aggregation. First level is from `RowBasedHashMapGenerator`, which is computation faster compared to the second level from `UnsafeFixedWidthAggregationMap`. The introducing of two level hash map can help improve CPU performance of query as the first level hash map normally fits in hardware cache and has cheaper hash function for key lookup.
For final hash aggregation, we can also support two level of hash map, to improve query performance further.
The original two level of hash map code works for final aggregation mostly out of box. The major change here is to support testing fall back of final aggregation (see change related to `bitMaxCapacity` and `checkFallbackForGeneratedHashMap`).
Example:
An aggregation query:
```
spark.sql(
"""
|SELECT key, avg(value)
|FROM agg1
|GROUP BY key
""".stripMargin)
```
The generated code for final aggregation is [here](https://gist.github.com/c21/20c10cc8e2c7e561aafbe9b8da055242).
An aggregation query with testing fallback:
```
withSQLConf("spark.sql.TungstenAggregate.testFallbackStartsAt" -> "2, 3") {
spark.sql(
"""
|SELECT key, avg(value)
|FROM agg1
|GROUP BY key
""".stripMargin)
}
```
The generated code for final aggregation is [here](https://gist.github.com/c21/dabf176cbc18a5e2138bc0a29e81c878). Note the no more counter condition for first level fast map.
### Why are the changes needed?
Improve the CPU performance of hash aggregation query in general.
For `AggregateBenchmark."Aggregate w multiple keys"`, seeing query performance improved by 10%.
`codegen = T` means whole stage code-gen is enabled.
`hashmap = T` means two level maps is enabled for partial aggregation.
`finalhashmap = T` means two level maps is enabled for final aggregation.

It will remove `StructField` when [pruning nested columns](0f2c0b53e8/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/SchemaPruning.scala (L28-L42)). For example:

spark.sql(
"""

spark.sql("INSERT INTO t1 values(1, '2', struct('a', 'b', 'c', 10L))")
spark.sql("SELECT _col0, _col2.c1 FROM t1").show
```
Before this pr. The returned schema is: ``` `_col0` INT,`_col2` STRUCT<`c1`: STRING> ``` add it will throw exception:
```

### What changes were proposed in this pull request?
* Add `Not(In)` and `Not(InSet)` check in `NullPropagation` rule.
* Add more test for `In` and `Not(In)` in `Project` level.
### Why are the changes needed?
The semantics of `Not(In)` could be seen like `And(a != b, a != c)` that match the `NullIntolerant`.
As we already simplify the `NullIntolerant` expression to null if it's children have null. E.g. `a != null` => `null`. It's safe to do this with `Not(In)`/`Not(InSet)`.
Note that, we can only do the simplify in predicate which `ReplaceNullWithFalseInPredicate` rule do.
Let's say we have two sqls:
```
select 1 not in (2, null);
select 1 where 1 not in (2, null);
```
The first sql we cannot optimize since it would return `NULL` instead of `false`. The second is postive.

This patch proposes to leverage `CustomMetric`, `CustomTaskMetric` API to report custom metrics from DS v2 scan to Spark.
### Why are the changes needed?
This is related to #31398. In SPARK-34297, we want to add a couple of metrics when reading from Kafka in SS. We need some public API change in DS v2 to make it possible. This extracts only DS v2 change and make it general for DS v2 instead of micro-batch DS v2 API.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Unit test.
Implement a simple test DS v2 class locally and run it:
```scala
scala> import org.apache.spark.sql.execution.datasources.v2._
import org.apache.spark.sql.execution.datasources.v2._
scala> classOf[CustomMetricDataSourceV2].getName
res0: String = org.apache.spark.sql.execution.datasources.v2.CustomMetricDataSourceV2
scala> val df = spark.read.format(res0).load()
df: org.apache.spark.sql.DataFrame = [i: int, j: int]
scala> df.collect
```

### What changes were proposed in this pull request?
This PR implements the decorrelation technique in the paper "Unnesting Arbitrary Queries" by T. Neumann; A. Kemper
(http://www.btw-2015.de/res/proceedings/Hauptband/Wiss/Neumann-Unnesting_Arbitrary_Querie.pdf). It currently supports Filter, Project, Aggregate, Join, and UnaryNode that passes CheckAnalysis.
This feature can be controlled by the config `spark.sql.optimizer.decorrelateInnerQuery.enabled` (default: true).
A few notes:
1. This PR does not relax any constraints in CheckAnalysis for correlated subqueries, even though some cases can be supported by this new framework, such as aggregate with correlated non-equality predicates. This PR focuses on adding the new framework and making sure all existing cases can be supported. Constraints can be relaxed gradually in the future via separate PRs.
2. The new framework is only enabled for correlated scalar subqueries, as the first step. EXISTS/IN subqueries can be supported in the future.
### Why are the changes needed?
Currently, Spark has limited support for correlated subqueries. It only allows `Filter` to reference outer query columns and does not support non-equality predicates when the subquery is aggregated. This new framework will allow more operators to host outer column references and support correlated non-equality predicates and more types of operators in correlated subqueries.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Existing unit and SQL query tests and new optimizer plan tests.

### What changes were proposed in this pull request?
This PR updated the `foundNonEqualCorrelatedPred` logic for correlated subqueries in `CheckAnalysis` to only allow correlated equality predicates that guarantee one-to-one mapping between inner and outer attributes, instead of all equality predicates.
### Why are the changes needed?
To fix correctness bugs. Before this fix Spark can give wrong results for certain correlated subqueries that pass CheckAnalysis:
Example 1:
```sql
create or replace view t1(c) as values ('a'), ('b')
create or replace view t2(c) as values ('ab'), ('abc'), ('bc')
select c, (select count(*) from t2 where t1.c = substring(t2.c, 1, 1)) from t1
```
Correct results: [(a, 2), (b, 1)]
Spark results:
```
+---+-----------------+
|c |scalarsubquery(c)|
+---+-----------------+
|a |1 |
|a |1 |
|b |1 |
+---+-----------------+
```
Example 2:
```sql
create or replace view t1(a, b) as values (0, 6), (1, 5), (2, 4), (3, 3);
create or replace view t2(c) as values (6);
select c, (select count(*) from t1 where a + b = c) from t2;
```
Correct results: [(6, 4)]
Spark results:
```
+---+-----------------+
|c |scalarsubquery(c)|
+---+-----------------+
|6 |1 |
|6 |1 |
|6 |1 |
|6 |1 |
+---+-----------------+
```
### Does this PR introduce _any_ user-facing change?
Yes. Users will not be able to run queries that contain unsupported correlated equality predicates.
### How was this patch tested?
Added unit tests.

## What changes were proposed in this pull request?
This PR fixes a couple of things in TypeCoercion rules:
- Only run the propagate types step if the children of a node have output attributes with changed dataTypes and/or nullability. This is implemented as custom tree transformation. The TypeCoercion rules now only implement a partial function.
- Combine multiple type coercion rules into a single rule. Multiple rules are applied in single tree traversal.
- Reduce calls to conf.get in DecimalPrecision. This now happens once per tree traversal, instead of once per matched expression.
- Reduce the use of withNewChildren.
This brings down the number of CPU cycles spend in analysis by ~28% (benchmark: 10 iterations of all TPC-DS queries on SF10).

### What changes were proposed in this pull request?
Firstly let's take a look at the definition and comment.
```
// A fake config which is only here for backward compatibility reasons. This config has no effect
// to Spark, just for reporting the builtin Hive version of Spark to existing applications that
// already rely on this config.
val FAKE_HIVE_VERSION = buildConf("spark.sql.hive.version")
.doc(s"deprecated, please use ${HIVE_METASTORE_VERSION.key} to get the Hive version in Spark.")
.version("1.1.1")
.fallbackConf(HIVE_METASTORE_VERSION)
```
It is used for reporting the built-in Hive version but the current status is unsatisfactory, as it is could be changed in many ways e.g. --conf/SET syntax.
It is marked as deprecated but kept a long way until now. I guess it is hard for us to remove it and not even necessary.
On second thought, it's actually good for us to keep it to work with the `spark.sql.hive.metastore.version`. As when `spark.sql.hive.metastore.version` is changed, it could be used to report the compiled hive version statically, it's useful when an error occurs in this case. So this parameter should be fixed to compiled hive version.
### Why are the changes needed?
`spark.sql.hive.version` is useful in certain cases and should be read-only
### Does this PR introduce _any_ user-facing change?
`spark.sql.hive.version` now is read-only

### What changes were proposed in this pull request?
Parse the year-month interval literals like `INTERVAL '1-1' YEAR TO MONTH` to values of `YearMonthIntervalType`, and day-time interval literals to `DayTimeIntervalType` values. Currently, Spark SQL supports:
- DAY TO HOUR
- DAY TO MINUTE
- DAY TO SECOND
- HOUR TO MINUTE
- HOUR TO SECOND
- MINUTE TO SECOND
All such interval literals are converted to `DayTimeIntervalType`, and `YEAR TO MONTH` to `YearMonthIntervalType` while loosing info about `from` and `to` units.
**Note**: new behavior is under the SQL config `spark.sql.legacy.interval.enabled` which is `false` by default. When the config is set to `true`, the interval literals are parsed to `CaledarIntervalType` values.
Closes#32176
### Why are the changes needed?
To conform the ANSI SQL standard which assumes conversions of interval literals to year-month or day-time interval but not to mixed interval type like Catalyst's `CalendarIntervalType`.
### Does this PR introduce _any_ user-facing change?
Yes.
Before:
```sql
spark-sql> SELECT INTERVAL '1 01:02:03.123' DAY TO SECOND;
1 days 1 hours 2 minutes 3.123 seconds
spark-sql> SELECT typeof(INTERVAL '1 01:02:03.123' DAY TO SECOND);
interval
```
After:
```sql
spark-sql> SELECT INTERVAL '1 01:02:03.123' DAY TO SECOND;
1 01:02:03.123000000
spark-sql> SELECT typeof(INTERVAL '1 01:02:03.123' DAY TO SECOND);
day-time interval
```
### How was this patch tested?
1. By running the affected test suites:
```
$ ./build/sbt "test:testOnly *.ExpressionParserSuite"
$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z interval.sql"
$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z create_view.sql"

$ SPARK_GENERATE_GOLDEN_FILES=1 build/sbt "sql/testOnly *SQLQueryTestSuite -- -z timestamp.sql"
```
2. PostgresSQL tests are executed with `spark.sql.legacy.interval.enabled` is set to `true` to keep compatibility with PostgreSQL output:
```sql
> SELECT interval '999' second;
0 years 0 mons 0 days 0 hours 16 mins 39.00 secs

### What changes were proposed in this pull request?
This PR:
- Adds a new expression `GroupingExprRef` that can be used in aggregate expressions of `Aggregate` nodes to refer grouping expressions by index. These expressions capture the data type and nullability of the referred grouping expression.
- Adds a new rule `EnforceGroupingReferencesInAggregates` that inserts the references in the beginning of the optimization phase.
- Adds a new rule `UpdateGroupingExprRefNullability` to update nullability of `GroupingExprRef` expressions as nullability of referred grouping expression can change during optimization.
### Why are the changes needed?
If aggregate expressions (without aggregate functions) in an `Aggregate` node are complex then the `Optimizer` can optimize out grouping expressions from them and so making aggregate expressions invalid.
Here is a simple example:
```
SELECT not(t.id IS NULL) , count(*)
FROM t
GROUP BY t.id IS NULL
```
In this case the `BooleanSimplification` rule does this:
```
=== Applying Rule org.apache.spark.sql.catalyst.optimizer.BooleanSimplification ===
!Aggregate [isnull(id#222)], [NOT isnull(id#222) AS (NOT (id IS NULL))#226, count(1) AS c#224L] Aggregate [isnull(id#222)], [isnotnull(id#222) AS (NOT (id IS NULL))#226, count(1) AS c#224L]
+- Project [value#219 AS id#222] +- Project [value#219 AS id#222]
+- LocalRelation [value#219] +- LocalRelation [value#219]
```
where `NOT isnull(id#222)` is optimized to `isnotnull(id#222)` and so it no longer refers to any grouping expression.
Before this PR:
```
== Optimized Logical Plan ==
Aggregate [isnull(id#222)], [isnotnull(id#222) AS (NOT (id IS NULL))#234, count(1) AS c#232L]
+- Project [value#219 AS id#222]
+- LocalRelation [value#219]
```
and running the query throws an error:
```
Couldn't find id#222 in [isnull(id#222)#230,count(1)#226L]
java.lang.IllegalStateException: Couldn't find id#222 in [isnull(id#222)#230,count(1)#226L]
```
After this PR:
```
== Optimized Logical Plan ==
Aggregate [isnull(id#222)], [NOT groupingexprref(0) AS (NOT (id IS NULL))#234, count(1) AS c#232L]
+- Project [value#219 AS id#222]
+- LocalRelation [value#219]
```
and the query works.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
The precision of `java.time.Duration` is nanosecond, but when it is used as `DayTimeIntervalType` in Spark, it is microsecond.
At present, the `DayTimeIntervalType` data generated in the implementation of `RandomDataGenerator` is accurate to nanosecond, which will cause the `DayTimeIntervalType` to be converted to long, and then back to `DayTimeIntervalType` to lose the accuracy, which will cause the test to fail.

### What changes were proposed in this pull request?
In current code, if we run spark sql with
```
./bin/spark-sql --verbose
```
It won't be passed to end SparkSQLCliDriver, then the SessionState won't call `setIsVerbose`
In the CLI option, it shows
```
CLI options:
-v,--verbose Verbose mode (echo executed SQL to the
console)
```
It's not consistent. This pr fix this issue
### Why are the changes needed?

### What changes were proposed in this pull request?
This PR refactors three parts of the comments in `HiveClientImpl.withHiveState`
One is about the following comment.
```
// The classloader in clientLoader could be changed after addJar, always use the latest
// classloader.
```
The comment was added in SPARK-10810 (#8909) because `IsolatedClientLoader.classLoader` was declared as `var`.
But the field is now `val` and cannot be changed after instanciation.
So, the comment can confuse developers.
One is about the following code and comment.
```
// classloader. We explicitly set the context class loader since "conf.setClassLoader" does
// not do that, and the Hive client libraries may need to load classes defined by the client's
// class loader.
Thread.currentThread().setContextClassLoader(clientLoader.classLoader)
```
It's not trivial why this part is necessary and it's difficult when we can remove this code in the future.
So, I revised the comment by adding the reference of the related JIRA.
And the last one is about the following code and comment.
```
// Replace conf in the thread local Hive with current conf
Hive.get(conf)
```
It's also not trivial why this part is necessary.
I revised the comment by adding the reference of the related discussion.
### Why are the changes needed?
To make code more readable.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
It's just a comment refactoring so I add no new test.

### What changes were proposed in this pull request?
Currently, pure SQL users are short of ways to see the Hadoop configurations which may affect their jobs a lot, they are only able to get the Hadoop configs that exist in `SQLConf` while other defaults in `SharedState.hadoopConf` display wrongly and confusingly with `<undefined>`.
The pre-loaded ones from `core-site.xml, hive-site.xml` etc., will only stay in `sparkSession.sharedState.hadoopConf` or `sc._hadoopConfiguation` not `SQLConf`. Some of them that related the Hive Metastore connection(never change it spark runtime), e.g. `hive.metastore.uris`, are clearly global static and unchangeable but displayable I guess. Some of the ones that might be related to, for example, the output codec/compression, preset in Hadoop/hive config files like core-site.xml shall be still changeable from case to case, table to table, file to file, etc. It' meaningfully to show the defaults for users to change based on that.
In this PR, I propose to support get a Hadoop configuration by SET syntax, for example
```
SET mapreduce.map.output.compress.codec;
```
### Why are the changes needed?
better user experience for pure SQL users
### Does this PR introduce _any_ user-facing change?
yes, where retrieving a conf only existing in sessionState.hadoopConf, before is `undefined` and now you see it

### What changes were proposed in this pull request?
Support `date +/- day-time interval`. In the PR, I propose to update the binary arithmetic rules, and cast an input date to a timestamp at the session time zone, and then add a day-time interval to it.
### Why are the changes needed?
1. To conform the ANSI SQL standard which requires to support such operation over dates and intervals:
<img width="811" alt="Screenshot 2021-03-12 at 11 36 14" src="https://user-images.githubusercontent.com/1580697/111081674-865d4900-8515-11eb-86c8-3538ecaf4804.png">
2. To fix the regression comparing to the recent Spark release 3.1 with default settings.
Before the changes:
```sql
spark-sql> select date'now' + (timestamp'now' - timestamp'yesterday');
Error in query: cannot resolve 'DATE '2021-04-14' + subtracttimestamps(TIMESTAMP '2021-04-14 18:14:56.497', TIMESTAMP '2021-04-13 00:00:00')' due to data type mismatch: argument 1 requires timestamp type, however, 'DATE '2021-04-14'' is of date type.; line 1 pos 7;

```
Spark 3.1:
```sql

2021-04-15
```
Hive:

```
### Does this PR introduce _any_ user-facing change?
Should not since new intervals have not been released yet.
After the changes:
```sql

### What changes were proposed in this pull request?
This PR proposes to introduce the `AnalysisOnlyCommand` trait such that a command that extends this trait can have its children only analyzed, but not optimized. There is a corresponding analysis rule `HandleAnalysisOnlyCommand` that marks the command as analyzed after all other analysis rules are run.
This can be useful if a logical plan has children where they need to be only analyzed, but not optimized - e.g., `CREATE VIEW` or `CACHE TABLE AS`. This also addresses the issue found in #31933.
This PR also updates `CreateViewCommand`, `CacheTableAsSelect`, and `AlterViewAsCommand` to use the new trait / rule such that their children are only analyzed.
### Why are the changes needed?
To address the issue where the plan is unnecessarily re-analyzed in `CreateViewCommand`.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
Adds the duplicated common columns as hidden columns to the Projection used to rewrite NATURAL/USING JOINs.
### Why are the changes needed?
Allows users to resolve either side of the NATURAL/USING JOIN's common keys.
Previously, the user could only resolve the following columns:
| Join type | Left key columns | Right key columns |
| --- | --- | --- |
| Inner | Yes | No |
| Left | Yes | No |
| Right | No | Yes |
| Outer | No | No |
### Does this PR introduce _any_ user-facing change?
Yes. The user can now symmetrically resolve the common columns from a NATURAL/USING JOIN.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR fixes an issue that `LIST FILES/JARS/ARCHIVES path1 path2 ...` cannot list all paths if at least one path is quoted.
An example here.
```
ADD FILE /tmp/test1;
ADD FILE /tmp/test2;
LIST FILES /tmp/test1 /tmp/test2;
file:/tmp/test1
file:/tmp/test2
LIST FILES /tmp/test1 "/tmp/test2";
file:/tmp/test2
```
In this example, the second `LIST FILES` doesn't show `file:/tmp/test1`.
To resolve this issue, I modified the syntax rule to be able to handle this case.
I also changed `SparkSQLParser` to be able to handle paths which contains white spaces.
### Why are the changes needed?
This is a bug.
I also have a plan which extends `ADD FILE/JAR/ARCHIVE` to take multiple paths like Hive and the syntax rule change is necessary for that.
### Does this PR introduce _any_ user-facing change?
Yes. Users can pass quoted paths when using `ADD FILE/JAR/ARCHIVE`.

### What changes were proposed in this pull request?
Populate table catalog and identifier from `DataStreamWriter` to `WriteToMicroBatchDataSource` so that we can invalidate cache for tables that are updated by a streaming write.
This is somewhat related [SPARK-27484](https://issues.apache.org/jira/browse/SPARK-27484) and [SPARK-34183](https://issues.apache.org/jira/browse/SPARK-34183) (#31700), as ideally we may want to replace `WriteToMicroBatchDataSource` and `WriteToDataSourceV2` with logical write nodes and feed them to analyzer. That will potentially change the code path involved in this PR.
### Why are the changes needed?
Currently `WriteToDataSourceV2` doesn't have cache invalidation logic, and therefore, when the target table for a micro batch streaming job is cached, the cache entry won't be removed when the table is updated.
### Does this PR introduce _any_ user-facing change?
Yes now when a DSv2 table which supports streaming write is updated by a streaming job, its cache will also be invalidated.
### How was this patch tested?

This PR allows non-aggregated correlated scalar subquery if the max output row is less than 2. Correlated scalar subqueries need to be aggregated because they are going to be decorrelated and rewritten as LEFT OUTER joins. If the correlated scalar subquery produces more than one output row, the rewrite will yield wrong results.
But this constraint can be relaxed when the subquery plan's the max number of output rows is less than or equal to 1.

1. **Union**: number of rows in output will be the sum of number of rows in the output for each child of union, min and max for each column in the output will be the min and max of that particular column coming from its children.
Example:
Table 1
a b
1 6
2 3
Table 2
a b
1 3
4 1
stats for table1 union table2 would be number of rows = 4, columnStats = (a: {min: 1, max: 4}, b: {min: 1, max: 6})
2. **Sort**: row and columns stats would be same as its children.
3. **Range**: number of output rows and distinct count will be equal to number of elements, min and max is calculated from start, end and step param.

2.2.2 Datatype
2.2.2.1 Each column employs one of the following datatypes:
a) Identifier means that the column shall be able to hold any key value generated for that column.
b) Integer means that the column shall be able to exactly represent integer values (i.e., values in increments of
1) in the range of at least ( − 2n − 1) to (2n − 1 − 1), where n is 64.
c) Decimal(d, f) means that the column shall be able to represent decimal values up to and including d digits,
of which f shall occur to the right of the decimal place; the values can be either represented exactly or
interpreted to be in this range.
d) Char(N) means that the column shall be able to hold any string of characters of a fixed length of N.
Comment: If the string that a column of datatype char(N) holds is shorter than N characters, then trailing
spaces shall be stored in the database or the database shall automatically pad with spaces upon retrieval such
that a CHAR_LENGTH() function will return N.
e) Varchar(N) means that the column shall be able to hold any string of characters of a variable length with a
maximum length of N. Columns defined as "varchar(N)" may optionally be implemented as "char(N)".
f) Date means that the column shall be able to express any calendar day between January 1, 1900 and
December 31, 2199.
2.2.2.2 The datatypes do not correspond to any specific SQL-standard datatype. The definitions are provided to
highlight the properties that are required for a particular column. The benchmark implementer may employ any internal representation or SQL datatype that meets those requirements.
```
This PR proposes that we use int for identifiers instead of bigint to reach a compromise with TPC-DS Standard Specification.

### What changes were proposed in this pull request?
For Spark SQL, it can't support script transform SQL with aggregationClause/windowClause/LateralView.
This case we can't directly migration Hive SQL to Spark SQL.
In this PR, we treat all script transform statement's query part (exclude transform about part) as a separate query block and solve it as ScriptTransformation's child and pass a UnresolvedStart as ScriptTransform's input. Then in analyzer level, we pass child's output as ScriptTransform's input. Then we can support all kind of normal SELECT query combine with script transformation.
Such as transform with aggregation:
```
SELECT TRANSFORM ( d2, max(d1) as max_d1, sum(d3))
USING 'cat' AS (a,b,c)
FROM script_trans
WHERE d1 <= 100
GROUP BY d2
HAVING max_d1 > 0
```
When we build AST, we treat it as
```
SELECT TRANSFORM (*)
USING 'cat' AS (a,b,c)
FROM (
SELECT d2, max(d1) as max_d1, sum(d3)
FROM script_trans
WHERE d1 <= 100
GROUP BY d2
HAVING max_d1 > 0
) tmp
```
then in Analyzer's `ResolveReferences`, resolve `* (UnresolvedStar)`, then sql behavior like
```
SELECT TRANSFORM ( d2, max(d1) as max_d1, sum(d3))
USING 'cat' AS (a,b,c)
FROM script_trans
WHERE d1 <= 100
GROUP BY d2
HAVING max_d1 > 0
```
About UT, in this pr we add a lot of different SQL to check we can support all kind of such SQL and each kind of expressions can work well, such as alias, case when, binary compute etc...
### Why are the changes needed?
Support transform with aggregateClause/windowClause/LateralView etc , make sql migration more smoothly
### Does this PR introduce _any_ user-facing change?
User can write transform with aggregateClause/windowClause/LateralView.
### How was this patch tested?

Support GROUP BY use Separate columns and CUBE/ROLLUP
In postgres sql, it support
```
select a, b, c, count(1) from t group by a, b, cube (a, b, c);
select a, b, c, count(1) from t group by a, b, rollup(a, b, c);
select a, b, c, count(1) from t group by cube(a, b), rollup (a, b, c);
select a, b, c, count(1) from t group by a, b, grouping sets((a, b), (a), ());
```
In this pr, we have done two things as below:
1. Support partial grouping analytics such as `group by a, cube(a, b)`
2. Support mixed grouping analytics such as `group by cube(a, b), rollup(b,c)`
*Partial Groupings*
Partial Groupings means there are both `group_expression` and `CUBE|ROLLUP|GROUPING SETS`
in GROUP BY clause. For example:
`GROUP BY warehouse, CUBE(product, location)` is equivalent to
`GROUP BY GROUPING SETS((warehouse, product, location), (warehouse, product), (warehouse, location), (warehouse))`.
`GROUP BY warehouse, ROLLUP(product, location)` is equivalent to
`GROUP BY GROUPING SETS((warehouse, product, location), (warehouse, product), (warehouse))`.
`GROUP BY warehouse, GROUPING SETS((product, location), (producet), ())` is equivalent to
`GROUP BY GROUPING SETS((warehouse, product, location), (warehouse, location), (warehouse))`.
*Concatenated Groupings*
Concatenated groupings offer a concise way to generate useful combinations of groupings. Groupings specified
with concatenated groupings yield the cross-product of groupings from each grouping set. The cross-product
operation enables even a small number of concatenated groupings to generate a large number of final groups.
The concatenated groupings are specified simply by listing multiple `GROUPING SETS`, `CUBES`, and `ROLLUP`,
and separating them with commas. For example:
`GROUP BY GROUPING SETS((warehouse), (producet)), GROUPING SETS((location), (size))` is equivalent to
`GROUP BY GROUPING SETS((warehouse, location), (warehouse, size), (product, location), (product, size))`.
`GROUP BY CUBE((warehouse), (producet)), ROLLUP((location), (size))` is equivalent to
`GROUP BY GROUPING SETS((warehouse, product), (warehouse), (producet), ()), GROUPING SETS((location, size), (location), ())`
`GROUP BY GROUPING SETS(
(warehouse, product, location, size), (warehouse, product, location), (warehouse, product),
(warehouse, location, size), (warehouse, location), (warehouse),
(product, location, size), (product, location), (product),
(location, size), (location), ())`.
`GROUP BY order, CUBE((warehouse), (producet)), ROLLUP((location), (size))` is equivalent to
`GROUP BY order, GROUPING SETS((warehouse, product), (warehouse), (producet), ()), GROUPING SETS((location, size), (location), ())`
`GROUP BY GROUPING SETS(
(order, warehouse, product, location, size), (order, warehouse, product, location), (order, warehouse, product),
(order, warehouse, location, size), (order, warehouse, location), (order, warehouse),
(order, product, location, size), (order, product, location), (order, product),
(order, location, size), (order, location), (order))`.
### Why are the changes needed?

### What changes were proposed in this pull request?
This PR contains:
- TreeNode, QueryPlan, AnalysisHelper changes to allow the transform function family to stop earlier without traversing the entire tree;
- Example changes in a few rules to support such pruning, e.g., ReorderJoin and OptimizeIn.
Here is a [design doc](https://docs.google.com/document/d/1SEUhkbo8X-0cYAJFYFDQhxUnKJBz4lLn3u4xR2qfWqk) that elaborates the ideas and benchmark numbers.
### Why are the changes needed?
It's a framework-level change for reducing the query compilation time.
In particular, if we update existing rules and transform call sites as per the examples in this PR, the analysis time and query optimization time can be reduced as described in this [doc](https://docs.google.com/document/d/1SEUhkbo8X-0cYAJFYFDQhxUnKJBz4lLn3u4xR2qfWqk) .

### What changes were proposed in this pull request?
1. Extend `IntervalUtils` methods: `toYearMonthIntervalString` and `toDayTimeIntervalString` to support formatting of year-month/day-time intervals in Hive style. The methods get new parameter style which can have to values; `HIVE_STYLE` and `ANSI_STYLE`.
2. Invoke `toYearMonthIntervalString` and `toDayTimeIntervalString` from the `Cast` expression with the `style` parameter is set to `ANSI_STYLE`.
3. Invoke `toYearMonthIntervalString` and `toDayTimeIntervalString` from `HiveResult` with `style` is set to `HIVE_STYLE`.
### Why are the changes needed?
The `spark-sql` shell formats its output in Hive style by using `HiveResult.hiveResultString()`. The changes are needed to match Hive behavior. For instance,
Hive:
```sql
0: jdbc:hive2://localhost:10000/default> select timestamp'2021-01-01 01:02:03.000001' - date'2020-12-31';
+-----------------------+
| _c0 |
+-----------------------+
| 1 01:02:03.000001000 |
+-----------------------+
```
Spark before the changes:
```sql
spark-sql> select timestamp'2021-01-01 01:02:03.000001' - date'2020-12-31';
INTERVAL '1 01:02:03.000001' DAY TO SECOND
```
Also this should unblock #32099 which enables *.sql tests in `SQLQueryTestSuite`.
### Does this PR introduce _any_ user-facing change?
Yes. After the changes:
```sql
spark-sql> select timestamp'2021-01-01 01:02:03.000001' - date'2020-12-31';
1 01:02:03.000001000
```
### How was this patch tested?
1. Added new tests to `IntervalUtilsSuite`:
```
$ build/sbt "test:testOnly *IntervalUtilsSuite"
```
2. Modified existing tests in `HiveResultSuite`:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "testOnly *HiveResultSuite"

3. By running cast tests:

### What changes were proposed in this pull request?
Implements `readShorts` in `VectorizedPlainValuesReader`, which decodes `total` shorts in the input buffer at one time, similar to other types.
### Why are the changes needed?
Currently `VectorizedRleValuesReader` reads short integer in the following way:
```java
for (int i = 0; i < n; i++) {
c.putShort(rowId + i, (short)data.readInteger());
}
```
For PLAIN encoding `data.readInteger` is done via:
```java
public final int readInteger() {
return getBuffer(4).getInt();
}
```
which means it needs to repeatedly call `slice` buffer for the batch size number of times. This is more expensive than calling it once in a big chunk and then reading the ints out.
Micro benchmark via `DataSourceReadBenchmark` showed ~35% perf improvement.

### What changes were proposed in this pull request?
One of the main performance bottlenecks in query compilation is overly-generic tree transformation methods, namely `mapChildren` and `withNewChildren` (defined in `TreeNode`). These methods have an overly-generic implementation to iterate over the children and rely on reflection to create new instances. We have observed that, especially for queries with large query plans, a significant amount of CPU cycles are wasted in these methods. In this PR we make these methods more efficient, by delegating the iteration and instantiation to concrete node types. The benchmarks show that we can expect significant performance improvement in total query compilation time in queries with large query plans (from 30-80%) and about 20% on average.
#### Problem detail
The `mapChildren` method in `TreeNode` is overly generic and costly. To be more specific, this method:
- iterates over all the fields of a node using Scala’s product iterator. While the iteration is not reflection-based, thanks to the Scala compiler generating code for `Product`, we create many anonymous functions and visit many nested structures (recursive calls).
The anonymous functions (presumably compiled to Java anonymous inner classes) also show up quite high on the list in the object allocation profiles, so we are putting unnecessary pressure on GC here.
- does a lot of comparisons. Basically for each element returned from the product iterator, we check if it is a child (contained in the list of children) and then transform it. We can avoid that by just iterating over children, but in the current implementation, we need to gather all the fields (only transform the children) so that we can instantiate the object using the reflection.
- creates objects using reflection, by delegating to the `makeCopy` method, which is several orders of magnitude slower than using the constructor.
#### Solution
The proposed solution in this PR is rather straightforward: we rewrite the `mapChildren` method using the `children` and `withNewChildren` methods. The default `withNewChildren` method suffers from the same problems as `mapChildren` and we need to make it more efficient by specializing it in concrete classes. Similar to how each concrete query plan node already defines its children, it should also define how they can be constructed given a new list of children. Actually, the implementation is quite simple in most cases and is a one-liner thanks to the copy method present in Scala case classes. Note that we cannot abstract over the copy method, it’s generated by the compiler for case classes if no other type higher in the hierarchy defines it. For most concrete nodes, the implementation of `withNewChildren` looks like this:
```
override def withNewChildren(newChildren: Seq[LogicalPlan]): LogicalPlan = copy(children = newChildren)
```
The current `withNewChildren` method has two properties that we should preserve:
- It returns the same instance if the provided children are the same as its children, i.e., it preserves referential equality.
- It copies tags and maintains the origin links when a new copy is created.
These properties are hard to enforce in the concrete node type implementation. Therefore, we propose a template method `withNewChildrenInternal` that should be rewritten by the concrete classes and let the `withNewChildren` method take care of referential equality and copying:
```
override def withNewChildren(newChildren: Seq[LogicalPlan]): LogicalPlan = {
if (childrenFastEquals(children, newChildren)) {
this
} else {
CurrentOrigin.withOrigin(origin) {
val res = withNewChildrenInternal(newChildren)
res.copyTagsFrom(this)
res
}
}
}
```
With the refactoring done in a previous PR (https://github.com/apache/spark/pull/31932) most tree node types fall in one of the categories of `Leaf`, `Unary`, `Binary` or `Ternary`. These traits have a more efficient implementation for `mapChildren` and define a more specialized version of `withNewChildrenInternal` that avoids creating unnecessary lists. For example, the `mapChildren` method in `UnaryLike` is defined as follows:
```
override final def mapChildren(f: T => T): T = {
val newChild = f(child)
if (newChild fastEquals child) {
this.asInstanceOf[T]
} else {
CurrentOrigin.withOrigin(origin) {
val res = withNewChildInternal(newChild)
res.copyTagsFrom(this.asInstanceOf[T])
res
}
}
}
```
#### Results
With this PR, we have observed significant performance improvements in query compilation time, more specifically in the analysis and optimization phases. The table below shows the TPC-DS queries that had more than 25% speedup in compilation times. Biggest speedups are observed in queries with large query plans.

|q98 |32%|
#### Binary incompatibility
Changing the `withNewChildren` in `TreeNode` breaks the binary compatibility of the code compiled against older versions of Spark because now it is expected that concrete `TreeNode` subclasses all implement the `withNewChildrenInternal` method. This is a problem, for example, when users write custom expressions. This change is the right choice, since it forces all newly added expressions to Catalyst implement it in an efficient manner and will prevent future regressions.
Please note that we have not completely removed the old implementation and renamed it to `legacyWithNewChildren`. This method will be removed in the future and for now helps the transition. There are expressions such as `UpdateFields` that have a complex way of defining children. Writing `withNewChildren` for them requires refactoring the expression. For now, these expressions use the old, slow method. In a future PR we address these expressions.

### What changes were proposed in this pull request?
Change UpdateAction and InsertAction of MergeIntoTable to explicitly represent star,
### Why are the changes needed?
Currently, UpdateAction and InsertAction in the MergeIntoTable implicitly represent `update set *` and `insert *` with empty assignments. That means there is no way to differentiate between the representations of "update all columns" and "update no columns". For SQL MERGE queries, this inability does not matter because the SQL MERGE grammar that generated the MergeIntoTable plan does not allow "update no columns". However, other ways of generating the MergeIntoTable plan may not have that limitation, and may want to allow specifying "update no columns". For example, in the Delta Lake project we provide a type-safe Scala API for Merge, where it is perfectly valid to produce a Merge query with an update clause but no update assignments. Currently, we cannot use MergeIntoTable to represent this plan, thus complicating the generation, and resolution of merge query from scala API.
Side note: fixed another bug where a merge plan with star and no other expressions with unresolved attributes (e.g. all non-optional predicates are `literal(true)`), then resolution will be skipped and star wont expanded. added test for that.

### What changes were proposed in this pull request?
This PR adds two additional checks in `CheckAnalysis` for correlated scalar subquery in Aggregate. It blocks the cases that Spark do not currently support based on the rewrite logic in `RewriteCorrelatedScalarSubquery`:
aff6c0febb/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/subquery.scala (L618-L624)
### Why are the changes needed?
It can be confusing to users when their queries pass the check analysis but cannot be executed. Also, the error messages are confusing:
#### Case 1: correlated scalar subquery in the grouping expressions but not in aggregate expressions
```sql
SELECT SUM(c2) FROM t t1 GROUP BY (SELECT SUM(c2) FROM t t2 WHERE t1.c1 = t2.c1)
```
We get this error:
```
java.lang.AssertionError: assertion failed: Expects 1 field, but got 2; something went wrong in analysis
```
because the correlated scalar subquery is not rewritten properly:
```scala

### What changes were proposed in this pull request?
This PR fixes an issue that `ADD JAR` command can't add jar files which contain whitespaces in the path though `ADD FILE` and `ADD ARCHIVE` work with such files.
If we have `/some/path/test file.jar` and execute the following command:
```
ADD JAR "/some/path/test file.jar";
```
The following exception is thrown.
```
21/04/05 10:40:38 ERROR SparkSQLDriver: Failed in [add jar "/some/path/test file.jar"]
java.lang.IllegalArgumentException: Illegal character in path at index 9: /some/path/test file.jar
at java.net.URI.create(URI.java:852)
at org.apache.spark.sql.hive.HiveSessionResourceLoader.addJar(HiveSessionStateBuilder.scala:129)
at org.apache.spark.sql.execution.command.AddJarCommand.run(resources.scala:34)
at org.apache.spark.sql.execution.command.ExecutedCommandExec.sideEffectResult$lzycompute(commands.scala:70)
at org.apache.spark.sql.execution.command.ExecutedCommandExec.sideEffectResult(commands.scala:68)
at org.apache.spark.sql.execution.command.ExecutedCommandExec.executeCollect(commands.scala:79)
```
This is because `HiveSessionStateBuilder` and `SessionStateBuilder` don't check whether the form of the path is URI or plain path and it always regards the path as URI form.
Whitespces should be encoded to `%20` so `/some/path/test file.jar` is rejected.
We can resolve this part by checking whether the given path is URI form or not.
Unfortunatelly, if we fix this part, another problem occurs.
When we execute `ADD JAR` command, Hive's `ADD JAR` command is executed in `HiveClientImpl.addJar` and `AddResourceProcessor.run` is transitively invoked.
In `AddResourceProcessor.run`, the command line is just split by `
s+` and the path is also split into `/some/path/test` and `file.jar` and passed to `ss.add_resources`.
f1e8713703/ql/src/java/org/apache/hadoop/hive/ql/processors/AddResourceProcessor.java (L56-L75)
So, the command still fails.
Even if we convert the form of the path to URI like `file:/some/path/test%20file.jar` and execute the following command:
```
ADD JAR "file:/some/path/test%20file";
```
The following exception is thrown.
```
21/04/05 10:40:53 ERROR SessionState: file:/some/path/test%20file.jar does not exist
java.lang.IllegalArgumentException: file:/some/path/test%20file.jar does not exist

at org.apache.hadoop.hive.ql.processors.AddResourceProcessor.run(AddResourceProcessor.java:74)
```
The reason is `Utilities.realFile` invoked in `SessionState.validateFiles` returns `null` as the result of `fs.exists(path)` is `false`.
f1e8713703/ql/src/java/org/apache/hadoop/hive/ql/exec/Utilities.java (L1052-L1064)
`fs.exists` checks the existence of the given path by comparing the string representation of Hadoop's `Path`.
The string representation of `Path` is similar to URI but it's actually different.
`Path` doesn't encode the given path.
For example, the URI form of `/some/path/jar file.jar` is `file:/some/path/jar%20file.jar` but the `Path` form of it is `file:/some/path/jar file.jar`. So `fs.exists` returns false.
So the solution I come up with is removing Hive's `ADD JAR` from `HiveClientimpl.addJar`.
I think Hive's `ADD JAR` was used to add jar files to the class loader for metadata and isolate the class loader from the one for execution.
https://github.com/apache/spark/pull/6758/files#diff-cdb07de713c84779a5308f65be47964af865e15f00eb9897ccf8a74908d581bbR94-R103
But, as of SPARK-10810 and SPARK-10902 (#8909) are resolved, the class loaders for metadata and execution seem to be isolated with different way.
https://github.com/apache/spark/pull/8909/files#diff-8ef7cabf145d3fe7081da799fa415189d9708892ed76d4d13dd20fa27021d149R635-R641
In the current implementation, such class loaders seem to be isolated by `SharedState.jarClassLoader` and `IsolatedClientLoader.classLoader`.
https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/internal/SessionState.scala#L173-L188https://github.com/apache/spark/blob/master/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L956-L967
So I wonder we can remove Hive's `ADD JAR` from `HiveClientImpl.addJar`.

## What changes were proposed in this pull request?
This adds a new API for catalog plugins that exposes functions to Spark. The API can list and load functions. This does not include create, delete, or alter operations.
- [Design Document](https://docs.google.com/document/d/1PLBieHIlxZjmoUB0ERF-VozCRJ0xw2j3qKvUNWpWA2U/edit?usp=sharing)
There are 3 types of functions defined:
* A `ScalarFunction` that produces a value for every call
* An `AggregateFunction` that produces a value after updates for a group of rows
Functions loaded from the catalog by name as `UnboundFunction`. Once input arguments are determined `bind` is called on the unbound function to get a `BoundFunction` implementation that is one of the 3 types above. Binding can fail if the function doesn't support the input type. `BoundFunction` returns the result type produced by the function.
## How was this patch tested?
This includes a test that demonstrates the new API.

### What changes were proposed in this pull request?
This PR extends the current function registry and catalog to support table-valued functions by adding a table function registry. It also refactors `range` to be a built-in function in the table function registry.
### Why are the changes needed?
Currently, Spark resolves table-valued functions very differently from the other functions. This change is to make the behavior for table and non-table functions consistent. It also allows Spark to display information about built-in table-valued functions:
Before:
```scala
scala> sql("describe function range").show(false)
+--------------------------+
|function_desc |
+--------------------------+
|Function: range not found.|
+--------------------------+
```
After:
```scala
Function: range
Class: org.apache.spark.sql.catalyst.plans.logical.Range
Usage:
range(start: Long, end: Long, step: Long, numPartitions: Int)
range(start: Long, end: Long, step: Long)
range(start: Long, end: Long)
range(end: Long)
// Extended
Function: range
Class: org.apache.spark.sql.catalyst.plans.logical.Range
Usage:
range(start: Long, end: Long, step: Long, numPartitions: Int)
range(start: Long, end: Long, step: Long)
range(start: Long, end: Long)
range(end: Long)
Extended Usage:
Examples:
> SELECT * FROM range(1);
+---+
| id|
+---+
| 0|
+---+
> SELECT * FROM range(0, 2);
+---+
|id |
+---+
|0 |
|1 |
+---+
> SELECT range(0, 4, 2);
+---+
|id |
+---+
|0 |
|2 |
+---+
Since: 2.0.0
```
### Does this PR introduce _any_ user-facing change?
Yes. User will not be able to create a function with name `range` in the default database:
Before:
```scala
scala> sql("create function range as 'range'")
res3: org.apache.spark.sql.DataFrame = []
```
After:
```
scala> sql("create function range as 'range'")
org.apache.spark.sql.catalyst.analysis.FunctionAlreadyExistsException: Function 'default.range' already exists in database 'default'
```

### What changes were proposed in this pull request?
Changed the cost comparison function of the CBO to use the ratios of row counts and sizes in bytes.
### Why are the changes needed?
In #30965 we changed to CBO cost comparison function so it would be "symetric": `A.betterThan(B)` now implies, that `!B.betterThan(A)`.
With that we caused a performance regressions in some queries - TPCDS q19 for example.
The original cost comparison function used the ratios `relativeRows = A.rowCount / B.rowCount` and `relativeSize = A.size / B.size`. The changed function compared "absolute" cost values `costA = w*A.rowCount + (1-w)*A.size` and `costB = w*B.rowCount + (1-w)*B.size`.
Given the input from wzhfy we decided to go back to the relative values, because otherwise one (size) may overwhelm the other (rowCount). But this time we avoid adding up the ratios.
Originally `A.betterThan(B) => w*relativeRows + (1-w)*relativeSize < 1` was used. Besides being "non-symteric", this also can exhibit one overwhelming other.
For `w=0.5` If `A` size (bytes) is at least 2x larger than `B`, then no matter how many times more rows does the `B` plan have, `B` will allways be considered to be better - `0.5*2 + 0.5*0.00000000000001 > 1`.
When working with ratios, then it would be better to multiply them.
The proposed cost comparison function is: `A.betterThan(B) => relativeRows^w * relativeSize^(1-w) < 1`.

q98 | 126 | 129 | 2.38% | 131 | 3.97%
All times are in ms, the change is compared to the situation in the master branch (absolute).
The proposed cost function (multiplicative) significantlly improves the performance on q18, q19 and q72. The original cost function (additive) has similar improvements at q18 and q19. All other chagnes are within the error bars and I would ignore them - perhaps q81 has also improved.

### What changes were proposed in this pull request?
Changes the metadata propagation framework.
Previously, most `LogicalPlan`'s propagated their `children`'s `metadataOutput`. This did not make sense in cases where the `LogicalPlan` did not even propagate their `children`'s `output`.
I set the metadata output for plans that do not propagate their `children`'s `output` to be `Nil`. Notably, `Project` and `View` no longer have metadata output.
### Why are the changes needed?
Previously, `SELECT m from (SELECT a from tb)` would output `m` if it were metadata. This did not make sense.
### Does this PR introduce _any_ user-facing change?
Yes. Now, `SELECT m from (SELECT a from tb)` will encounter an `AnalysisException`.

### What changes were proposed in this pull request?
GROUP BY ... GROUPING SETS (...) is a weird SQL syntax we copied from Hive. It's not in the SQL standard or any other mainstream databases. This syntax requires users to repeat the expressions inside `GROUPING SETS (...)` after `GROUP BY`, and has a weird null semantic if `GROUP BY` contains extra expressions than `GROUPING SETS (...)`.
This PR deprecates this syntax:
1. Do not promote it in the document and only mention it as a Hive compatible sytax.
2. Simplify the code to only keep it for Hive compatibility.
### Why are the changes needed?
Deprecate a weird grammar.
### Does this PR introduce _any_ user-facing change?
No breaking change, but it removes a check to simplify the code: `GROUP BY a GROUPING SETS(a, b)` fails before and forces users to also put `b` after `GROUP BY`. Now this works just as `GROUP BY GROUPING SETS(a, b)`.

### What changes were proposed in this pull request?
https://github.com/apache/spark/pull/32015 added a way to run benchmarks much more easily in the same GitHub Actions build. This PR updates the benchmark results by using the way.
**NOTE** that looks like GitHub Actions use four types of CPU given my observations:
- Intel(R) Xeon(R) Platinum 8171M CPU 2.60GHz
- Intel(R) Xeon(R) CPU E5-2673 v4 2.30GHz
- Intel(R) Xeon(R) CPU E5-2673 v3 2.40GHz
- Intel(R) Xeon(R) Platinum 8272CL CPU 2.60GHz
Given my quick research, seems like they perform roughly similarly:
I couldn't find enough information about Intel(R) Xeon(R) Platinum 8272CL CPU 2.60GHz but the performance seems roughly similar given the numbers.
So shouldn't be a big deal especially given that this way is much easier, encourages contributors to run more and guarantee the same number of cores and same memory with the same softwares.

### What changes were proposed in this pull request?
In the PR, I propose to disable ANSI intervals as the result of dates/timestamp subtraction in `ExtractBenchmark` and benchmark only legacy intervals because `EXTRACT( .. FROM ..)` doesn't support ANSI intervals so far.
### Why are the changes needed?
This fixes the benchmark failure:
```

### What changes were proposed in this pull request?
This PR introduces a new analysis rule `DeduplicateRelations`, which deduplicates any duplicate relations in a plan first and then deduplicates conflicting attributes(which resued the `dedupRight` of `ResolveReferences`).
### Why are the changes needed?
`CostBasedJoinReorder` could fail when applying on self-join, e.g.,
```scala
// test in JoinReorderSuite
test("join reorder with self-join") {
val plan = t2.join(t1, Inner, Some(nameToAttr("t1.k-1-2") === nameToAttr("t2.k-1-5")))
.select(nameToAttr("t1.v-1-10"))
.join(t2, Inner, Some(nameToAttr("t1.v-1-10") === nameToAttr("t2.k-1-5")))
// this can fail
Optimize.execute(plan.analyze)
}
```
Besides, with the new rule `DeduplicateRelations`, we'd be able to enable some optimizations, e.g., LeftSemiAnti pushdown, redundant project removal, as reflects in updated unit tests.

### What changes were proposed in this pull request?
This PR is to support nested column type in Spark ORC vectorized reader. Currently ORC vectorized reader [does not support nested column type (struct, array and map)](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/orc/OrcFileFormat.scala#L138). We implemented nested column vectorized reader for FB-ORC in our internal fork of Spark. We are seeing performance improvement compared to non-vectorized reader when reading nested columns. In addition, this can also help improve the non-nested column performance when reading non-nested and nested columns together in one query.
Before this PR:
* `OrcColumnVector` is the implementation class for Spark's `ColumnVector` to wrap Hive's/ORC's `ColumnVector` to read `AtomicType` data.
After this PR:
* `OrcColumnVector` is an abstract class to keep interface being shared between multiple implementation class of orc column vectors, namely `OrcAtomicColumnVector` (for `AtomicType`), `OrcArrayColumnVector` (for `ArrayType`), `OrcMapColumnVector` (for `MapType`), `OrcStructColumnVector` (for `StructType`). So the original logic to read `AtomicType` data is moved from `OrcColumnVector` to `OrcAtomicColumnVector`. The abstract class of `OrcColumnVector` is needed here because of supporting nested column (i.e. nested column vectors).
* A utility method `OrcColumnVectorUtils.toOrcColumnVector` is added to create Spark's `OrcColumnVector` from Hive's/ORC's `ColumnVector`.
* A new user-facing config `spark.sql.orc.enableNestedColumnVectorizedReader` is added to control enabling/disabling vectorized reader for nested columns. The default value is false (i.e. disabling by default). For certain tables having deep nested columns, vectorized reader might take too much memory for each sub-column vectors, compared to non-vectorized reader. So providing a config here to work around OOM for query reading wide and deep nested columns if any. We plan to enable it by default on 3.3. Leave it disable in 3.2 in case for any unknown bugs.
### Why are the changes needed?
Improve query performance when reading nested columns from ORC file format.
Tested with locally adding a small benchmark in `OrcReadBenchmark.scala`. Seeing more than 1x run time improvement.

For aggregate functions, that do not ignore NULL values (`First`, `Last` or `UDAF`s) the current approach can return wrong results.
In the added UT there are no nulls in the input `testData`. The query returned `Row(0, 1, 0, 51, 100)` before this PR.

### What changes were proposed in this pull request?
Add a new SQL function `try_cast`.
`try_cast` is identical to `AnsiCast` (or `Cast` when `spark.sql.ansi.enabled` is true), except it returns NULL instead of raising an error.
This expression has one major difference from `cast` with `spark.sql.ansi.enabled` as true: when the source value can't be stored in the target integral(Byte/Short/Int/Long) type, `try_cast` returns null instead of returning the low order bytes of the source value.
Note that the result of `try_cast` is not affected by the configuration `spark.sql.ansi.enabled`.
This is learned from Google BigQuery and Snowflake:
https://docs.snowflake.com/en/sql-reference/functions/try_cast.htmlhttps://cloud.google.com/bigquery/docs/reference/standard-sql/functions-and-operators#safe_casting
### Why are the changes needed?
This is an useful for the following scenarios:
1. When ANSI mode is on, users can choose `try_cast` an alternative way to run SQL without errors for certain operations.
2. When ANSI mode is off, users can use `try_cast` to get a more reasonable result for casting a value to an integral type: when an overflow error happens, `try_cast` returns null while `cast` returns the low order bytes of the source value.
### Does this PR introduce _any_ user-facing change?
Yes, adding a new function `try_cast`
### How was this patch tested?

### What changes were proposed in this pull request?
Spark query plan node hierarchy has specialized traits (or abstract classes) for handling nodes with fixed number of children, for example `UnaryExpression`, `UnaryNode` and `UnaryExec` for representing an expression, a logical plan and a physical plan with only one child, respectively. This PR refactors the `TreeNode` hierarchy by extracting the children handling functionality into the following traits. `UnaryExpression` and other similar classes now extend the corresponding new trait:
```
trait LeafLike[T <: TreeNode[T]] { self: TreeNode[T] =>
override final def children: Seq[T] = Nil
}
trait UnaryLike[T <: TreeNode[T]] { self: TreeNode[T] =>
def child: T
transient override final lazy val children: Seq[T] = child :: Nil
}
trait BinaryLike[T <: TreeNode[T]] { self: TreeNode[T] =>
def left: T
def right: T
transient override final lazy val children: Seq[T] = left :: right :: Nil
}
trait TernaryLike[T <: TreeNode[T]] { self: TreeNode[T] =>
def first: T
def second: T
def third: T
transient override final lazy val children: Seq[T] = first :: second :: third :: Nil
}
```
This refactoring, which is part of a bigger effort to make tree transformations in Spark more efficient, has two benefits:
- It moves the children handling methods to a single place, instead of being spread in specific subclasses, which will help the future optimizations for tree traversals.
- It allows to mix in these traits with some concrete node types that could not extend the previous classes. For example, expressions with one child that extend `AggregateFunction` cannot extend `UnaryExpression` as `AggregateFunction` defines the `foldable` method final while `UnaryExpression` defines it as non final. With the new traits, we can directly extend the concrete class from `UnaryLike` in these cases. Classes with more specific child handling will make tree traversal methods faster.
In this PR we have also updated many concrete node types to extend these traits to benefit from more specific child handling.

We need to rewrite current Grouping Analytics grammar to support as flexible as Postgres SQL to support subsequent development.
In postgres sql, it support
```
select a, b, c, count(1) from t group by cube (a, b, c);
select a, b, c, count(1) from t group by cube(a, b, c);
select a, b, c, count(1) from t group by cube (a, b, c, (a, b), (a, b, c));
select a, b, c, count(1) from t group by rollup(a, b, c);
select a, b, c, count(1) from t group by rollup (a, b, c);
select a, b, c, count(1) from t group by rollup (a, b, c, (a, b), (a, b, c));
```
In this pr, we have done three things as below, and we will split it to different pr:
- Refactor CUBE/ROLLUP (regarding them as ANTLR tokens in a parser)
- Refactor GROUPING SETS (the logical node -> a new expr)
- Support new syntax for CUBE/ROLLUP (e.g., GROUP BY CUBE ((a, b), (a, c)))

### What changes were proposed in this pull request?
Some `spark-submit` commands used to run benchmarks in the user's guide is wrong, we can't use these commands to run benchmarks successful.
So the major changes of this pr is correct these wrong commands, for example, run a benchmark which inherits from `SqlBasedBenchmark`, we must specify `--jars <spark core test jar>,<spark catalyst test jar>` because `SqlBasedBenchmark` based benchmark extends `BenchmarkBase(defined in spark core test jar)` and `SQLHelper(defined in spark catalyst test jar)`.
Another change of this pr is removed the `scalatest Assertions` dependency of Benchmarks because `scalatest-*.jar` are not in the distribution package, it will be troublesome to use.
### Why are the changes needed?
Make sure benchmarks can run using spark-submit cmd described in the guide
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Use the corrected `spark-submit` commands to run benchmarks successfully.

spark.sql("create table t2(x int, y int, z int) using parquet")
spark.sql("select a from t1 left join t2 on a = x and b = y limit 5").explain("extended")
```
```

### What changes were proposed in this pull request?
This PR proposes to extend the functionality of requirement for distribution and ordering on V2 write to specify the number of partitioning on repartition, so that data source is able to control the parallelism and determine the data distribution per partition in prior.
The partitioning with static number is optional, and by default disabled via default method, so only implementations required to restrict the number of partition statically need to override the method and provide the number.
Note that we don't support static number of partitions with unspecified distribution for this PR, as we haven't found the real use cases, and for hypothetical case the static number isn't good enough. Javadoc clearly describes the limitation.
### Why are the changes needed?
The use case comes from feature parity with DSv1.
I have state data source which enables the state in SS to be rewritten, which enables repartitioning, schema evolution, etc via batch query. The writer requires hash partitioning against group key, with the "desired number of partitions", which is same as what Spark does read and write against state.
This is now implemented as DSv1, and the requirement is simply done by calling repartition with the "desired number".
```
val fullPathsForKeyColumns = keySchema.map(key => new Column(s"key.${key.name}"))
data
.repartition(newPartitions, fullPathsForKeyColumns: _*)
.queryExecution
.toRdd
.foreachPartition(
writeFn(resolvedCpLocation, version, operatorId, storeName, keySchema, valueSchema,
storeConf, hadoopConfBroadcast, queryId))
```
Thanks to SPARK-34026, it's now possible to require the hash partitioning, but still not able to require the number of partitions. This PR will enable to let data source require the number of partitions.
### Does this PR introduce _any_ user-facing change?
Yes, but only for data source implementors. Even for them, this is no breaking change as default method is added.
### How was this patch tested?
Added UTs.

### What changes were proposed in this pull request?
The changes being proposed are to increase the accuracy of JDBCRelation's stride calculation, as outlined in: https://issues.apache.org/jira/browse/SPARK-34843
In summary:
Currently, in JDBCRelation (line 123), the stride size is calculated as follows:
val stride: Long = upperBound / numPartitions - lowerBound / numPartitions
Due to truncation happening on both divisions, the stride size can fall short of what it should be. This can lead to a big difference between the provided upper bound and the actual start of the last partition.
I'm proposing a different formula that doesn't truncate to early, and also maintains accuracy using fixed-point decimals. This helps tremendously with the size of the last partition, which can be even more amplified if there is data skew in that direction. In a real-life test, I've seen a 27% increase in performance with this more proper stride alignment. The reason for fixed-point decimals instead of floating-point decimals is because inaccuracy due to limitation of what the float can represent. This may seem small, but could shift the midpoint a bit, and depending on how granular the data is, that could translate to quite a difference. It's also just inaccurate, and I'm striving to make the partitioning as accurate as possible, within reason.
Lastly, since the last partition's predicate is determined by how the strides align starting from the lower bound (plus one stride), there can be skew introduced creating a larger last partition compared to the first partition. Therefore, after calculating a more precise stride size, I've also introduced logic to move the first partition's predicate (which is an offset from the lower bound) to a position that closely matches the offset of the last partition's predicate (in relation to the upper bound). This makes the first and last partition more evenly distributed compared to each other, and helps with the last task being the largest (reducing its size).
### Why are the changes needed?
The current implementation is inaccurate and can lead to the last task/partition running much longer than previous tasks. Therefore, you can end up with a single node/core running for an extended period while other nodes/cores are sitting idle.
### Does this PR introduce _any_ user-facing change?
No. I would suspect some users will just get a good performance increase. As stated above, if we were to run our code on Spark that has this change implemented, we would have all of the sudden got a 27% increase in performance.
### How was this patch tested?
I've added two new unit tests. I did need to update one unit test, but when you look at the comparison of the before and after, you'll see better alignment of the partitioning with the new implementation. Given that the lower partition's predicate is exclusive and the upper's is inclusive, the offset of the lower was 3 days, and the offset of the upper was 6 days... that's potentially twice the amount of data in that upper partition (could be much more depending on how the user's data is distributed).
Other unit tests that utilize timestamps and two partitions have maintained their midpoint.
### Examples
I've added results with and without the realignment logic to better highlight both improvements this PR brings.
**Example 1:**
Given the following partition config:
"lowerBound" -> "1930-01-01"
"upperBound" -> "2020-12-31"
"numPartitions" -> 1000
_Old method (exactly what it would be BEFORE this PR):_
First partition: "PartitionColumn" < '1930-02-02' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2017-07-11'
_Old method, but with new realingment logic of first partition:_
First partition: "PartitionColumn" < '1931-10-14' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2019-03-22'
_New method:_
First partition: "PartitionColumn" < '1930-02-03' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2020-04-05'
_New with new realingment logic of first partition (exactly what it would be AFTER this PR):_
First partition: "PartitionColumn" < '1930-06-02' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2020-08-02'
**Example 2:**
Given the following partition config:
"lowerBound" -> "1927-04-05",
"upperBound" -> "2020-10-16"
"numPartitions" -> 2000
_Old method (exactly what it would be BEFORE this PR):_
First partition: "PartitionColumn" < '1927-04-21' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2014-10-29'
_Old method, but with new realingment logic of first partition::_
First partition: "PartitionColumn" < '1930-04-07' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2017-10-15'
_New method:_
First partition: "PartitionColumn" < '1927-04-22' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2020-04-19'
_New method with new realingment logic of first partition (exactly what it would be AFTER this PR):_
First partition: "PartitionColumn" < '1927-07-13' or "PartitionColumn" is null
Last partition: "PartitionColumn" >= '2020-07-10'

A companion PR for SPARK-34817, when we handle the unsigned int(<=32) logical types. In this PR, we map the unsigned int64 to decimal(20, 0) for better compatibility.
### Why are the changes needed?
Spark won't have unsigned types, but spark should be able to read existing parquet files written by other systems that support unsigned types for better compatibility.
### Does this PR introduce _any_ user-facing change?
yes, we can read parquet uint64 now
### How was this patch tested?
new unit tests

### What changes were proposed in this pull request?
Move the checkpoint location resolving into the rule ResolveWriteToStream, which is added in SPARK-34748.
### Why are the changes needed?
After SPARK-34748, we have a rule ResolveWriteToStream for the analysis logic for the resolving logic of stream write plans. Based on it, we can further move the checkpoint location resolving work in the rule. Then, all the checkpoint resolving logic was done in the analyzer.

### What changes were proposed in this pull request?
This is a follow-up of https://github.com/apache/spark/pull/31940 . This PR generalizes the matching of attributes and outer references, so that outer references are handled everywhere.
Note that, currently correlated subquery has a lot of limitations in Spark, and the newly covered cases are not possible to happen. So this PR is a code refactor.

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

### What changes were proposed in this pull request?
This PR intends to fix the bug that does not apply right-padding for char types inside correlated subquries.
For example, a query below returns nothing in master, but a correct result is `c`.
```
scala> sql(s"CREATE TABLE t1(v VARCHAR(3), c CHAR(5)) USING parquet")
scala> sql(s"CREATE TABLE t2(v VARCHAR(5), c CHAR(7)) USING parquet")
scala> sql("INSERT INTO t1 VALUES ('c', 'b')")
scala> sql("INSERT INTO t2 VALUES ('a', 'b')")
scala> val df = sql("""
|SELECT v FROM t1
|WHERE 'a' IN (SELECT v FROM t2 WHERE t2.c = t1.c )""".stripMargin)
scala> df.show()
+---+
| v|
+---+
+---+
```
This is because `ApplyCharTypePadding` does not handle the case above to apply right-padding into `'abc'`. This PR modifies the code in `ApplyCharTypePadding` for handling it correctly.

### What changes were proposed in this pull request?
Currently, when implicit casting a data type to a `TypeCollection`, Spark returns the first convertible data type among `TypeCollection`.
In ANSI mode, we can make the behavior more reasonable by returning the closet convertible data type in `TypeCollection`.
In details, we first try to find the all the expected types we can implicitly cast:
1. if there is no convertible data types, return None;
2. if there is only one convertible data type, cast input as it;
3. otherwise if there are multiple convertible data types, find the closet data
type among them. If there is no such closet data type, return None.
Note that if the closet type is Float type and the convertible types contains Double type, simply return Double type as the closet type to avoid potential
precision loss on converting the Integral type as Float type.
### Why are the changes needed?
Make the type coercion rule for TypeCollection more reasonable and ANSI compatible.
E.g. returning Long instead of Double for`implicast(int, TypeCollect(Double, Long))`.
From ANSI SQL Spec section 4.33 "SQL-invoked routines"
Section 9.6 "Subject routine determination"
Section 10.4 "routine invocation"
### Does this PR introduce _any_ user-facing change?
Yes, in ANSI mode, implicit casting to a `TypeCollection` returns the narrowest convertible data type instead of the first convertible one.
### How was this patch tested?
Unit tests.

### What changes were proposed in this pull request?
Both local limit and global limit define the output partitioning and output ordering in the same way and this is duplicated (https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/limit.scala#L159-L175 ). We can move the output partitioning and ordering into their parent trait - `BaseLimitExec`. This is doable as `BaseLimitExec` has no more other child class. This is a minor code refactoring.

### What changes were proposed in this pull request?
For permanent views (and the new SQL temp view in Spark 3.1), we store the view SQL text and re-parse/analyze the view SQL text when reading the view. In the case of `SELECT * FROM ...`, we want to avoid view schema change (e.g. the referenced table changes its schema) and will record the view query output column names when creating the view, so that when reading the view we can add a `SELECT recorded_column_names FROM ...` to retain the original view query schema.
In Spark 3.1 and before, the final SELECT is added after the analysis phase: https://github.com/apache/spark/blob/branch-3.1/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/view.scala#L67
If the view query has duplicated output column names, we always pick the first column when reading a view. A simple repro:
```
scala> sql("create view c(x, y) as select 1 a, 2 a")
res0: org.apache.spark.sql.DataFrame = []
scala> sql("select * from c").show
+---+---+
| x| y|
+---+---+
| 1| 1|
+---+---+
```
In the master branch, we will fail at the view reading time due to b891862fb6 , which adds the final SELECT during analysis, so that the query fails with `Reference 'a' is ambiguous`
This PR proposes to resolve the view query output column names from the matching attributes by ordinal.
For example, `create view c(x, y) as select 1 a, 2 a`, the view query output column names are `[a, a]`. When we reading the view, there are 2 matching attributes (e.g.`[a#1, a#2]`) and we can simply match them by ordinal.
A negative example is
```
create table t(a int)
create view v as select *, 1 as col from t
replace table t(a int, col int)
```
When reading the view, the view query output column names are `[a, col]`, and there are two matching attributes of `col`, and we should fail the query. See the tests for details.

### What changes were proposed in this pull request?
This patch proposes to add a few public API change to DS v2, to make DS v2 scan can report metrics to Spark.
Two public interfaces are added.
* `CustomMetric`: metric interface at the driver side. It basically defines how Spark aggregates task metrics with the same metric name.
* `CustomTaskMetric`: task metric reported at executors. It includes a name and long value. Spark will collect these metric values and update internal metrics.
There are two public methods added to existing public interfaces. They are optional to DS v2 implementations.
* `PartitionReader.currentMetricsValues()`: returns an array of CustomTaskMetric. Here is where the actual metrics values are collected. Empty array by default.
* `Scan.supportedCustomMetrics()`: returns an array of supported custom metrics `CustomMetric`. Empty array by default.
### Why are the changes needed?
In order to report custom metrics, we need some public API change in DS v2 to make it possible.

### What changes were proposed in this pull request?
This bug was introduced by SPARK-30428 at Apache Spark 3.0.0.
This PR fixes `FileScan.equals()`.
### Why are the changes needed?
- Without this fix `FileScan.equals` doesn't take `fileIndex` and `readSchema` into account.
- Partition filters and data filters added to `FileScan` (in #27112 and #27157) caused that canonicalized form of some `BatchScanExec` nodes don't match and this prevents some reuse possibilities.
### Does this PR introduce _any_ user-facing change?
Yes, before this fix incorrect reuse of `FileScan` and so `BatchScanExec` could have happed causing correctness issues.
### How was this patch tested?
Added new UTs.

### What changes were proposed in this pull request?
This patch proposes to disable fetching shuffle blocks in batch when io encryption is enabled. Adaptive Query Execution fetch contiguous shuffle blocks for the same map task in batch to reduce IO and improve performance. However, we found that batch fetching is incompatible with io encryption.
### Why are the changes needed?
Before this patch, we set `spark.io.encryption.enabled` to true, then run some queries which coalesced partitions by AEQ, may got following error message:

Now that all the temporary views are wrapped with `TemporaryViewRelation`(#31273, #31652, and #31825), this PR proposes to update `SessionCatalog`'s APIs for temporary views to take or return more concrete types.
APIs that will take `TemporaryViewRelation` instead of `LogicalPlan`:
```

### What changes were proposed in this pull request?
This PR fixes the `HybridRowQueue ` to respect the configured memory mode.
Besides, this PR also refactored the constructor of `MemoryConsumer` to accept the memory mode explicitly.
### Why are the changes needed?
`HybridRowQueue` supports both onHeap and offHeap manipulation. But it inherited the wrong `MemoryConsumer` constructor, which hard-coded the memory mode to `onHeap`.
### Does this PR introduce _any_ user-facing change?
No. (Maybe yes in some cases where users can't complete the job before could complete successfully after the fix because of `HybridRowQueue` is able to spill under offHeap mode now. )
### How was this patch tested?
Updated the existing test to make it test both offHeap and onHeap modes.

### What changes were proposed in this pull request?
This PR proposes to optimize WAL commit phase via following changes:
* cache offset log to avoid FS get operation per batch
* just directly delete instead of employing FS list operation on purge
### Why are the changes needed?
There're inefficiency on WAL commit phase which can be easily optimized via using a small driver memory.
1. To provide the offset metadata to source side (via `source.commit()`), we read offset metadata for previous batch from file system, which is probably written by this driver in previous batches. Caching it into driver memory would reduce the get operation.
2. Spark calls purge against offset log & commit log per batch, which calls list operation. If the previous batch succeeded to purge, the current batch just needs to check one batch which can be simply done via direct delete operation, instead of calling list operation.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Manually tested with additional debug log. (Verified that cache is used, cache keeps the size as 2, only one delete call is used instead of list call)
Did some experiment with simple rate to console query. (NOTE: wasn't done with master branch - tested against Spark 2.4.x, but WAL commit phase hasn't been changed AFAIK during these versions)

### What changes were proposed in this pull request?
This PR fixes an incompatible behavior introduced by #31754.
The problem is that quoted name parts represented as a string are given to the constructor of `UnresolvedAttribute` which takes single string parameter, `sql` method invocation against the `UnresolvedAttrribute` returns different result than before.
One example is ``` UnresolvedAttribute("`a.b`").sql ```. This returned `a.b` before but it doesn't now.
See [this duscussion](https://github.com/apache/spark/pull/31754/files#r597181927) for more details.

Since Spark 3.0， the `libthrift` has been bumped up from 0.9.3 to 0.12.0.
Due to THRIFT-4805, The SparkThrift Server will print annoying TExceptions. For example, the current thrift server module test in Github action workflow outputs more than 200MB of data for this error only

I checked the latest `hive-service-rpc` module in the maven center, https://mvnrepository.com/artifact/org.apache.hive/hive-service-rpc/3.1.2. It still uses the 0.9.3 version.
Unfortunately, I tried the newly released `libthrift 0.14.1`(w/o shading it), it breaks the metastore client side.
```scala
java.lang.NoSuchMethodError: org.apache.thrift.transport.TSocket.<init>(Ljava/lang/String;II)V
```
On the Thrift side, they just muted it see https://issues.apache.org/jira/browse/THRIFT-4805
So in this PR, I add a filter to suppress the warning

### What changes were proposed in this pull request?
This PR is to fix the LIMIT code-gen bug in https://issues.apache.org/jira/browse/SPARK-34796, where the counter variable from `BaseLimitExec` is not initialized but used in code-gen. This is because the limit counter variable will be used in upstream operators (LIMIT's child plan, e.g. `ColumnarToRowExec` operator for early termination), but in the same stage, there can be some operators doing the shortcut and not calling `BaseLimitExec`'s `doConsume()`, e.g. [HashJoin.codegenInner](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/HashJoin.scala#L402). So if we have query that `LocalLimit - BroadcastHashJoin - FileScan` in the same stage, the whole stage code-gen compilation will be failed.
Here is an example:
```
test("failed limit query") {
withTable("left_table", "empty_right_table", "output_table") {
spark.range(5).toDF("k").write.saveAsTable("left_table")
spark.range(0).toDF("k").write.saveAsTable("empty_right_table")
withSQLConf(SQLConf.ADAPTIVE_EXECUTION_ENABLED.key -> "false") {
spark.sql("CREATE TABLE output_table (k INT) USING parquet")
spark.sql(
s"""
|INSERT INTO TABLE output_table
|SELECT t1.k FROM left_table t1
|JOIN empty_right_table t2
|ON t1.k = t2.k
|LIMIT 3
|""".stripMargin)
}
}
}
```

Codegen failure - https://gist.github.com/c21/ea760c75b546d903247582be656d9d66 .
The uninitialized variable `_limit_counter_1` from `LocalLimitExec` is referenced in `ColumnarToRowExec`, but `BroadcastHashJoinExec` does not call `LocalLimitExec.doConsume()` to initialize the counter variable.
The fix is to move the counter variable initialization to `doProduce()`, as in whole stage code-gen framework, `doProduce()` will definitely be called if upstream operators `doProduce()`/`doConsume()` is called.
Note: this only happens in AQE disabled case, because we have an AQE optimization rule [EliminateUnnecessaryJoin](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/adaptive/EliminateUnnecessaryJoin.scala#L69) to change the whole query to an empty `LocalRelation` if inner join broadcast side is empty with AQE enabled.
### Why are the changes needed?

### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
For all built-in datasources, prohibit saving of year-month and day-time intervals that were introduced by SPARK-27793. We plan to support saving of such types at the milestone 2, see SPARK-27790.
### Why are the changes needed?
To improve user experience with Spark SQL, and print nicer error message. Current error message might confuse users:
```

### What changes were proposed in this pull request?
This is a follow-up of https://github.com/apache/spark/pull/31671https://github.com/apache/spark/pull/31671 has an unexpected behavior change that it uses a different Hadoop conf (`sparkContext.hadoopConfiguration`) to instantiate `FileSystem`, which is used to qualify the warehouse path. Before https://github.com/apache/spark/pull/31671 , the Hadoop conf to instantiate `FileSystem` is `session.sessionState.newHadoopConf()`.
More specifically, `session.sessionState.newHadoopConf()` has more conf entries:
1. it includes configs from `SharedState.initialConfigs`
2. in includes configs from `sparkContext.conf`
This PR updates `SharedState` to use the final Hadoop conf to instantiate `FileSystem`.
### Why are the changes needed?
fix behavior change
### Does this PR introduce _any_ user-facing change?
yes, the behavior will be the same before https://github.com/apache/spark/pull/31671
### How was this patch tested?

### What changes were proposed in this pull request?
Change context classloader to Spark classloader at `RebaseDateTime.loadRebaseRecords`
### Why are the changes needed?
With custom `spark.sql.hive.metastore.version` and `spark.sql.hive.metastore.jars`.
Spark would use date formatter in `HiveShim` that convert `date` to `string`, if we set `spark.sql.legacy.timeParserPolicy=LEGACY` and the partition type is `date` the `RebaseDateTime` code will be invoked. At that moment, if `RebaseDateTime` is initialized the first time then context class loader is `IsolatedClientLoader`. Such error msg would throw:

### What changes were proposed in this pull request?
Support `timestamp +/- day-time interval`. In the PR, I propose to extend the `TimeAdd` expression and support `DayTimeIntervalType` as the `interval` parameter. The expression invokes the new method `DateTimeUtils.timestampAddDayTime()` which splits the input day-time interval to `days` and `microsecond adjustment` of a day, and adds `days` (and the microseconds) to a local timestamp derived from the given timestamp at the given time zone. The resulted local timestamp is converted back to the offset in microseconds since the epoch.
Also I updated the rules that handle `CalendarIntervalType` and produce `TimeAdd` to take into account new type `DateTimeIntervalType` for the `interval` parameter of `TimeAdd`.
### Why are the changes needed?
To conform the ANSI SQL standard which requires to support such operation over timestamps and intervals:

### What changes were proposed in this pull request?
In `EliminateJoinToEmptyRelation.scala`, we can extend it to cover more cases for LEFT SEMI and LEFT ANI joins:
* Join is left semi join, join right side is non-empty and condition is empty. Eliminate join to its left side.
* Join is left anti join, join right side is empty. Eliminate join to its left side.
Given we eliminate join to its left side here, renaming the current optimization rule to `EliminateUnnecessaryJoin` instead.
In addition, also change to use `checkRowCount()` to check run time row count, instead of using `EmptyHashedRelation`. So this can cover `BroadcastNestedLoopJoin` as well. (`BroadcastNestedLoopJoin`'s broadcast side is `Array[InternalRow]`, not `HashedRelation`).
### Why are the changes needed?
Cover more join cases, and improve query performance for affected queries.

No.

### What changes were proposed in this pull request?
This PR proposes an alternative way to fix the memory leak of `ExecutionListenerBus`, which would automatically clean them up.
Basically, the idea is to add `registerSparkListenerForCleanup` to `ContextCleaner`, so we can remove the `ExecutionListenerBus` from `LiveListenerBus` when the `SparkSession` is GC'ed.
On the other hand, to make the `SparkSession` GC-able, we need to get rid of the reference of `SparkSession` in `ExecutionListenerBus`. Therefore, we introduced the `sessionUUID`, which is a unique identifier for SparkSession, to replace the `SparkSession` object.
Note that, the proposal wouldn't take effect when `spark.cleaner.referenceTracking=false` since it depends on `ContextCleaner`.
### Why are the changes needed?
Fix the memory leak caused by `ExecutionListenerBus` mentioned in SPARK-34087.
### Does this PR introduce _any_ user-facing change?
Yes, save memory for users.

### What changes were proposed in this pull request?
This PR fixes the build failure with Scala 2.13 which is related to `commons-cli`.
The last few days, build with Scala 2.13 on GA continues to fail and the error message says like as follows.
```
[error] /home/runner/work/spark/spark/sql/hive-thriftserver/src/main/java/org/apache/hive/service/server/HiveServer2.java:26:1: error: package org.apache.commons.cli does not exist
1278[error] import org.apache.commons.cli.GnuParser;
```
The reason is that `mvn help` in `change-scala-version.sh` downloads the POM file of `commons-cli` but doesn't download the JAR file, leading the build failure.
This PR also adds `commons-cli` to the dependencies explicitly because HiveThriftServer depends on it.
### Why are the changes needed?
Expect to fix the build failure with Scala 2.13.

No.

### What changes were proposed in this pull request?
This PR proposes to follow Univocity's input buffer.
### Why are the changes needed?
- Firstly, it's best to trust their judgement on the default values. Also 128 is too low.
- Default values arguably have more test coverage in Univocity.
- It will also fix https://github.com/uniVocity/univocity-parsers/issues/449
- ^ is a regression compared to Spark 2.4
### Does this PR introduce _any_ user-facing change?
No. In addition, It fixes a regression.
### How was this patch tested?
Manually tested, and added a unit test.

### What changes were proposed in this pull request?
This PR updates `InMemoryCatalog.tableExists` to return false if database doesn't exist, instead of failing. The new behavior is consistent with `HiveExternalCatalog` which is used in production, so this bug mostly only affects tests.

### What changes were proposed in this pull request?
`TmpOutputFile` and `TmpErrOutputFile` are registered in `o.a.h.u.ShutdownHookManager `during creatation. The `state.close()` will delete them if they are not null and try remove them from the `o.a.h.u.ShutdownHookManager` which causes IllegalStateException when we call it in our ShutdownHookManager too.
In this PR, we delete them ahead with a high priority hook in Spark and set them to null to bypass the deletion and canceling in `state.close()`
### Why are the changes needed?
W/ or w/o this PR, the deletion of these files is not affected, we just mute an undesirable error log here.

### What changes were proposed in this pull request?
Push down limit through `Window` when the partitionSpec of all window functions is empty and the same order is used. This is a real case from production:
This pr support 2 cases:
1. All window functions have same orderSpec:
```sql
SELECT *, ROW_NUMBER() OVER(ORDER BY a) AS rn, RANK() OVER(ORDER BY a) AS rk FROM t1 LIMIT 5;
== Optimized Logical Plan ==
Window [row_number() windowspecdefinition(a#9L ASC NULLS FIRST, specifiedwindowframe(RowFrame, unboundedpreceding$(), currentrow$())) AS rn#4, rank(a#9L) windowspecdefinition(a#9L ASC NULLS FIRST, specifiedwindowframe(RowFrame, unboundedpreceding$(), currentrow$())) AS rk#5], [a#9L ASC NULLS FIRST]
+- GlobalLimit 5
+- LocalLimit 5
+- Sort [a#9L ASC NULLS FIRST], true
+- Relation default.t1[A#9L,B#10L,C#11L] parquet
```
2. There is a window function with a different orderSpec:
```sql
SELECT a, ROW_NUMBER() OVER(ORDER BY a) AS rn, RANK() OVER(ORDER BY b DESC) AS rk FROM t1 LIMIT 5;
== Optimized Logical Plan ==
Project [a#9L, rn#4, rk#5]
+- Window [rank(b#10L) windowspecdefinition(b#10L DESC NULLS LAST, specifiedwindowframe(RowFrame, unboundedpreceding$(), currentrow$())) AS rk#5], [b#10L DESC NULLS LAST]

### What changes were proposed in this pull request?
This PR proposes:
1. `CREATE OR REPLACE TEMP VIEW USING` should use `TemporaryViewRelation` to store temp views.
2. By doing #1, it fixes the issue where the temp view being replaced is not uncached.
### Why are the changes needed?
This is a part of an ongoing work to wrap all the temporary views with `TemporaryViewRelation`: [SPARK-34698](https://issues.apache.org/jira/browse/SPARK-34698).
This also fixes a bug where the temp view being replaced is not uncached.
### Does this PR introduce _any_ user-facing change?
Yes, the temp view being replaced with `CREATE OR REPLACE TEMP VIEW USING` is correctly uncached if the temp view is cached.
### How was this patch tested?

For DDL commands like DROP VIEW, they don't really need to resolve the view (parse and analyze the view SQL text), they just need to get the view metadata.

### What changes were proposed in this pull request?
We initialized a Hive `SessionState` to interact with the external hive metastore server but left it behind after we finished.
We should close the metastore client explicitly in case of connection leaks with HMS
and we should trigger the `SessionState` to close itself to clean the residual dirs to fix issues reported by SPARK-21449 and SPARK-23745.
`hive.downloaded.resources.dir` contains transient files, such as UDF jars, it will not be used anymore after spark applications exit.
### Why are the changes needed?
1. prevent potential metastore client leak
2. clean `hive.downloaded.resources.dir`
```

### What changes were proposed in this pull request?
Support `timestamp +/- year-month interval`. In the PR, I propose to introduce new binary expression `TimestampAddYMInterval` similarly to `DateAddYMInterval`. It invokes new method `timestampAddMonths` from `DateTimeUtils` by passing a timestamp as an offset in microseconds since the epoch, amount of months from the giveb year-month interval, and the time zone ID in which the operation is performed. The `timestampAddMonths()` method converts the input microseconds to a local timestamp, adds months to it, and converts the results back to an instant in microseconds at the given time zone.
### Why are the changes needed?
To conform the ANSI SQL standard which requires to support such operation over timestamps and intervals:

### What changes were proposed in this pull request?
This PR aims to make `ExpressionEncoderSuite` to use `deepEquals` instead of `equals` when `input` is `array of array`.

### Why are the changes needed?
Currently, the interpreted mode fails for `array of array` because the following line is used.
```

### What changes were proposed in this pull request?
For `BroadcastNestedLoopJoinExec` left semi and left anti join without condition. If we broadcast left side. Currently we check whether every row from broadcast side has a match or not by [iterating broadcast side a lot of time](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/BroadcastNestedLoopJoinExec.scala#L256-L275). This is unnecessary and very inefficient when there's no condition, as we only need to check whether stream side is empty or not. Create this PR to add the optimization. This can boost the affected query execution performance a lot.
In addition, create a common method `getMatchedBroadcastRowsBitSet()` shared by several methods.
Refactor `defaultJoin()` to move
* left semi and left anti join related logic to `leftExistenceJoin`
* existence join related logic to `existenceJoin`.
After this, `defaultJoin()` holds logic only for outer join (left outer, right outer and full outer), which is much easier to read from my own opinion.
### Why are the changes needed?
Improve the affected query performance a lot.
Test with a simple query by modifying `JoinBenchmark.scala` locally:
```
val N = 20 << 20
val M = 1 << 4
val dim = broadcast(spark.range(M).selectExpr("id as k"))
val df = dim.join(spark.range(N), Seq.empty, "left_semi")
df.noop()
```
See >30x run time improvement. Note the stream side is only `spark.range(N)`. For complicated query with non-trivial stream side, the saving would be much more.

In the PR, I propose to cast the input float to double in the `SecondsToTimestamp` expression in the same way as in the `Cast` expression.

```sql
spark-sql> SELECT CAST(16777215.0f AS TIMESTAMP);
1970-07-14 07:20:15

### What changes were proposed in this pull request?
In non-ANSI mode, casting float to timestamp has different implementation for codegen on and off.
Codegen on:
1. Multiply float input by MICROS_PER_SECOND
2. Cast resulting float value to long
Codegen off:
1. CAST float input to double input
2. Multiply double input by MICROS_PER_SECOND
3. Cast resulting double value to long
In the PR, I propose to align to non-codegen code, and cast input float to double in codegen.
### Why are the changes needed?
This fixes the issue which is demonstrated by the code:
```sql
spark-sql> CREATE TEMP VIEW v1 AS SELECT 16777215.0f AS f;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:15
spark-sql> CACHE TABLE v1;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:14.951424
```
The result from the cached view **1970-07-14 07:20:14.951424** is different from un-cached view **1970-07-14 07:20:15**.
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above outputs the same timestamp for the cached view:
```sql
spark-sql> CACHE TABLE v1;
spark-sql> SELECT * FROM v1;
1.6777215E7
spark-sql> SELECT CAST(f AS TIMESTAMP) FROM v1;
1970-07-14 07:20:15

### What changes were proposed in this pull request?
This bug was introduced by SPARK-23583 at Apache Spark 2.4.0.
This PR aims to use `getMethod` instead of `getDeclaredMethod`.
```scala
- obj.getClass.getDeclaredMethod(functionName, argClasses: _*)
+ obj.getClass.getMethod(functionName, argClasses: _*)
```
### Why are the changes needed?
`getDeclaredMethod` does not search the super class's method. To invoke `GenericArrayData.toIntArray`, we need to use `getMethod` because it's declared at the super class `ArrayData`.

### What changes were proposed in this pull request?
In the PR, I propose to especially handle the amount of seconds `-9223372036855` in `IntervalUtils. durationToMicros()`. Starting from the amount (any durations with the second field < `-9223372036855`), input durations cannot fit to `Long` in the conversion to microseconds. For example, the amount of microseconds = `Long.MinValue = -9223372036854775808` can be represented in two forms:
1. seconds = -9223372036854, nanoAdjustment = -775808, or
2. seconds = -9223372036855, nanoAdjustment = +224192
And the method `Duration.ofSeconds()` produces the last form but such form causes overflow while converting `-9223372036855` seconds to microseconds.
In the PR, I propose to convert the second form to the first one if the second field of input duration is equal to `-9223372036855`.
### Why are the changes needed?
The changes fix the issue demonstrated by the code:
```scala
scala> durationToMicros(microsToDuration(Long.MinValue))
java.lang.ArithmeticException: long overflow
at java.lang.Math.multiplyExact(Math.java:892)
at org.apache.spark.sql.catalyst.util.IntervalUtils$.durationToMicros(IntervalUtils.scala:782)
... 49 elided
```
The `durationToMicros()` method cannot handle valid output of `microsToDuration()`.
### Does this PR introduce _any_ user-facing change?
Should not since new interval types has not been released yet.
### How was this patch tested?
By running new UT from `IntervalUtilsSuite`.

### What changes were proposed in this pull request?
Add `Not(In)` and `Not(InSet)` pattern when convert filter to metastore.
### Why are the changes needed?
`NOT IN` is a useful condition to prune partition, it would be better to support it.
Technically, we can convert `c not in(x,y)` to `c != x and c != y`, then push it to metastore.
Avoid metastore overflow and respect the config `spark.sql.hive.metastorePartitionPruningInSetThreshold`, `Not(InSet)` won't push to metastore if it's value exceeds the threshold.

### What changes were proposed in this pull request?
SPARK-23596 added `CodegenInterpretedPlanTest` at Apache Spark 2.4.0 in a wrong way because `withSQLConf` depends on the execution time `SQLConf.get` instead of `test` function declaration time. So, the following code executes the test twice without controlling the `CodegenObjectFactoryMode`. This PR aims to fix it correct and introduce a new function `testFallback`.
```scala
trait CodegenInterpretedPlanTest extends PlanTest {
override protected def test(
testName: String,
testTags: Tag*)(testFun: => Any)(implicit pos: source.Position): Unit = {
val codegenMode = CodegenObjectFactoryMode.CODEGEN_ONLY.toString
val interpretedMode = CodegenObjectFactoryMode.NO_CODEGEN.toString
withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> codegenMode) {
super.test(testName + " (codegen path)", testTags: _*)(testFun)(pos)
}
withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> interpretedMode) {
super.test(testName + " (interpreted path)", testTags: _*)(testFun)(pos)
}
}
}
```
### Why are the changes needed?
1. We need to use like the following.
```scala
super.test(testName + " (codegen path)", testTags: _*)(
withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> codegenMode) { testFun })(pos)
super.test(testName + " (interpreted path)", testTags: _*)(
withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key -> interpretedMode) { testFun })(pos)
```
2. After we fix this behavior with the above code, several test cases including SPARK-34596 and SPARK-34607 fail because they didn't work at both `CODEGEN` and `INTERPRETED` mode. Those test cases only work at `FALLBACK` mode. So, inevitably, we need to introduce `testFallback`.

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

### What changes were proposed in this pull request?
This PR proposes the following:
* `AlterViewAs.query` is currently analyzed in the physical operator `AlterViewAsCommand`, but it should be analyzed during the analysis phase.
* When `spark.sql.legacy.storeAnalyzedPlanForView` is set to true, store `TermporaryViewRelation` which wraps the analyzed plan, similar to #31273.
* Try to uncache the view you are altering.
### Why are the changes needed?
Analyzing a plan should be done in the analysis phase if possible.
Not uncaching the view (existing behavior) seems like a bug since the cache may not be used again.
### Does this PR introduce _any_ user-facing change?
Yes, now the view can be uncached if it's already cached.
### How was this patch tested?
Added new tests around uncaching.
The existing tests such as `SQLViewSuite` should cover the analysis changes.

### What changes were proposed in this pull request?
There is a regression in 3.1.1 compared to 3.0.2 when checking for a canonicalized plan when executing CustomShuffleReaderExec.

### What changes were proposed in this pull request?
For full outer shuffled hash join with building hash map on left side, and having non-equal condition, the join can produce wrong result.
The root cause is `boundCondition` in `HashJoin.scala` always assumes the left side row is `streamedPlan` and right side row is `buildPlan` ([streamedPlan.output ++ buildPlan.output](https://github.com/apache/spark/blob/branch-3.1/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/HashJoin.scala#L141)). This is valid assumption, except for full outer + build left case.
The fix is to correct `boundCondition` in `HashJoin.scala` to handle full outer + build left case properly. See reproduce in https://issues.apache.org/jira/browse/SPARK-32399?focusedCommentId=17298414&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17298414 .

### What changes were proposed in this pull request?
In the PR, I propose to extend Spark SQL API to accept [`java.time.Period`](https://docs.oracle.com/javase/8/docs/api/java/time/Period.html) as an external type of recently added new Catalyst type - `YearMonthIntervalType` (see #31614). The Java class `java.time.Period` has similar semantic to ANSI SQL year-month interval type, and it is the most suitable to be an external type for `YearMonthIntervalType`. In more details:
1. Added `PeriodConverter` which converts `java.time.Period` instances to/from internal representation of the Catalyst type `YearMonthIntervalType` (to `Int` type). The `PeriodConverter` object uses new methods of `IntervalUtils`:
- `periodToMonths()` converts the input period to the total length in months. If this period is too large to fit `Int`, the method throws the exception `ArithmeticException`. **Note:** _the input period has "days" precision, the method just ignores the days unit._
- `monthToPeriod()` obtains a `java.time.Period` representing a number of months.
2. Support new type `YearMonthIntervalType` in `RowEncoder` via the methods `createDeserializerForPeriod()` and `createSerializerForJavaPeriod()`.
3. Extended the Literal API to construct literals from `java.time.Period` instances.
### Why are the changes needed?
1. To allow users parallelization of `java.time.Period` collections, and construct year-month interval columns. Also to collect such columns back to the driver side.
2. This will allow to write tests in other sub-tasks of SPARK-27790.
### Does this PR introduce _any_ user-facing change?
The PR extends existing functionality. So, users can parallelize instances of the `java.time.Duration` class and collect them back:
```scala
scala> val ds = Seq(java.time.Period.ofYears(10).withMonths(2)).toDS
ds: org.apache.spark.sql.Dataset[java.time.Period] = [value: yearmonthinterval]
scala> ds.collect
res0: Array[java.time.Period] = Array(P10Y2M)
```
### How was this patch tested?
- Added a few tests to `CatalystTypeConvertersSuite` to check conversion from/to `java.time.Period`.
- Checking row encoding by new tests in `RowEncoderSuite`.
- Making literals of `YearMonthIntervalType` are tested in `LiteralExpressionSuite`.
- Check collecting by `DatasetSuite` and `JavaDatasetSuite`.
- New tests in `IntervalUtilsSuites` to check conversions `java.time.Period` <-> months.

pyrolite 4.21 introduced and enabled value comparison by default (`valueCompare=true`) during object memoization and serialization: https://github.com/irmen/Pyrolite/blob/pyrolite-4.21/java/src/main/java/net/razorvine/pickle/Pickler.java#L112-L122
This change has undesired effect when we serialize a row (actually `GenericRowWithSchema`) to be passed to python: https://github.com/apache/spark/blob/branch-3.0/sql/core/src/main/scala/org/apache/spark/sql/execution/python/EvaluatePython.scala#L60. A simple example is that
```
new GenericRowWithSchema(Array(1.0, 1.0), StructType(Seq(StructField("_1", DoubleType), StructField("_2", DoubleType))))
```
and
```
new GenericRowWithSchema(Array(1, 1), StructType(Seq(StructField("_1", IntegerType), StructField("_2", IntegerType))))
```
are currently equal and the second instance is replaced to the short code of the first one during serialization.
### Why are the changes needed?
The above can cause nasty issues like the one in https://issues.apache.org/jira/browse/SPARK-34545 description:
```
>>> from pyspark.sql.functions import udf
>>> from pyspark.sql.types import *
>>>
>>> def udf1(data_type):
def u1(e):
return e[0]
return udf(u1, data_type)
>>>
>>> df = spark.createDataFrame([((1.0, 1.0), (1, 1))], ['c1', 'c2'])
>>>
>>> df = df.withColumn("c3", udf1(DoubleType())("c1"))
>>> df = df.withColumn("c4", udf1(IntegerType())("c2"))
>>>
>>> df.select("c3").show()
+---+
| c3|
+---+
|1.0|
+---+
>>> df.select("c4").show()
+---+

+---+
| 1|
+---+
>>> df.select("c3", "c4").show()
+---+----+
| c3| c4|
+---+----+
|1.0|null|
+---+----+
```
This is because during serialization from JVM to Python `GenericRowWithSchema(1.0, 1.0)` (`c1`) is memoized first and when `GenericRowWithSchema(1, 1)` (`c2`) comes next, it is replaced to some short code of the `c1` (instead of serializing `c2` out) as they are `equal()`. The python functions then runs but the return type of `c4` is expected to be `IntegerType` and if a different type (`DoubleType`) comes back from python then it is discarded: https://github.com/apache/spark/blob/branch-3.0/sql/core/src/main/scala/org/apache/spark/sql/execution/python/EvaluatePython.scala#L108-L113
After this PR:
```
>>> df.select("c3", "c4").show()

+---+---+
```

### What changes were proposed in this pull request?
It's a bit confusing to see `resolveExpressionBottomUp` and `resolveExpressionTopDown`, which provide similar functionalities but with different tree traverse order. It turns out that the real difference between these 2 methods is: which attributes should the columns be resolved to? `resolveExpressionTopDown` resolves columns using output attributes of the plan children, `resolveExpressionBottomUp` resolves columns using output attributes of the plan itself.
This PR unifies `resolveExpressionBottomUp` and `resolveExpressionTopDown` and put the common logic in a new method, and let `resolveExpressionBottomUp` and `resolveExpressionTopDown` just call the new method. This PR also renames `resolveExpressionBottomUp` and `resolveExpressionTopDown` to make the difference clear.

This PR intends to fix a bug of `objects.NewInstance` if a user runs Spark on jdk8u and a given `cls` in `NewInstance` is a deeply-nested inner class, e.g.,.

}}}}}}}}}}}}}}}}}}}}
```
The root cause that Kris (rednaxelafx) investigated is as follows (Kudos to Kris);
The reason why the test case above is so convoluted is in the way Scala generates the class name for nested classes. In general, Scala generates a class name for a nested class by inserting the dollar-sign ( `$` ) in between each level of class nesting. The problem is that this format can concatenate into a very long string that goes beyond certain limits, so Scala will change the class name format beyond certain length threshold.
For the example above, we can see that the first two levels of class nesting have class names that look like this:
```
org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite$OuterLevelWithVeryVeryVeryLongClassName1$
org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite$OuterLevelWithVeryVeryVeryLongClassName1$OuterLevelWithVeryVeryVeryLongClassName2$
```
If we leave out the fact that Scala uses a dollar-sign ( `$` ) suffix for the class name of the companion object, `OuterLevelWithVeryVeryVeryLongClassName1`'s full name is a prefix (substring) of `OuterLevelWithVeryVeryVeryLongClassName2`.
But if we keep going deeper into the levels of nesting, you'll find names that look like:
```
org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite$OuterLevelWithVeryVeryVeryLongClassNam$$$$2a1321b953c615695d7442b2adb1$$$$ryVeryLongClassName8$OuterLevelWithVeryVeryVeryLongClassName9$OuterLevelWithVeryVeryVeryLongClassName10$

with a hash code in the middle and various levels of nesting omitted.
The `java.lang.Class.isMemberClass` method is implemented in JDK8u as:
http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/tip/src/share/classes/java/lang/Class.java#l1425
```
/**
* Returns {code true} if and only if the underlying class
* is a member class.
*
* return {code true} if and only if this class is a member class.
* since 1.5
*/
public boolean isMemberClass() {
return getSimpleBinaryName() != null && !isLocalOrAnonymousClass();
}
/**
* Returns the "simple binary name" of the underlying class, i.e.,
* the binary name without the leading enclosing class name.
* Returns {code null} if the underlying class is a top level
* class.
*/
private String getSimpleBinaryName() {
Class<?> enclosingClass = getEnclosingClass();
if (enclosingClass == null) // top level class
return null;
// Otherwise, strip the enclosing class' name
try {
return getName().substring(enclosingClass.getName().length());
} catch (IndexOutOfBoundsException ex) {
throw new InternalError("Malformed class name", ex);
}
}
```
and the problematic code is `getName().substring(enclosingClass.getName().length())` -- if a class's enclosing class's full name is *longer* than the nested class's full name, this logic would end up going out of bounds.
The bug has been fixed in JDK9 by https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8057919 , but still exists in the latest JDK8u release. So from the Spark side we'd need to do something to avoid hitting this problem.

6b34745cb9/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/StreamExecution.scala (L332-L335)
wouldn't take effect if callers access them from the active SQLConf, e.g., the rule of `InsertAdaptiveSparkPlan`. Besides, unlike `InsertAdaptiveSparkPlan` (which skips streaming plan), `CostBasedJoinReorder` seems to have the chance to take effect theoretically.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
Add the `ResetSystemProperties` trait to `SQLQuerySuite` so that system property changes made by any of the tests will not affect other suites/tests. Specifically, the system property changes made by `SPARK-33084: Add jar support Ivy URI in SQL -- jar contains udf class` are targeted here (which sets and then clears `ivy.home`).
### Why are the changes needed?
PR #29966 added a new test case that adjusts the `ivy.home` system property to force Ivy to resolve an artifact from a custom location. At the end of the test, the value is cleared. Clearing the value meant that, if a custom value of `ivy.home` was configured externally, it would not apply for tests run after this test case.
### Does this PR introduce _any_ user-facing change?
No, this is only in tests.
### How was this patch tested?
Existing unit tests continue to pass, whether or not `spark.jars.ivySettings` is configured (which adjusts the behavior of Ivy w.r.t. handling of `ivy.home` and `ivy.default.ivy.user.dir` properties).

### What changes were proposed in this pull request?
In the PR, I propose to extend Catalyst's type system by two new types that conform to the SQL standard (see SQL:2016, section 4.6.3):
- `DayTimeIntervalType` represents the day-time interval type,
- `YearMonthIntervalType` for SQL year-month interval type.
This PR only adds the two new DataType implementations, and there will be more PRs as sub-tasks of SPARK-27790 to completely support the new ANSI interval types.
### Why are the changes needed?
Spark as it is today supports an INTERVAL datatype. However this type is of very limited use. Existing interval values cannot be compared with any other interval values, or persisted to storage. Spark users request to either implement new or expand existing built-in functions which produce some sort of measures for elapsed time, such as `DATEDIFF()`. Rather than work around the edges to fill the potholes of the existing INTERVAL data type, I would like to propose to deliver a proper ANSI compliant INTERVAL type that can be introduced with minimal incompatibility, is comparable and thus sortable, and can be persisted in tables.

### What changes were proposed in this pull request?
`BroadcastNestedLoopJoinExec` does not preserve `outputPartitioning` and `outputOrdering` right now. But it can preserve the streamed side partitioning and ordering when possible. This can help avoid shuffle and sort in later stage, if there's join and aggregation in the query. See example queries in added unit test in `JoinSuite.scala`.
In addition, fix a bunch of minor places in `BroadcastNestedLoopJoinExec.scala` for better style and readability.

### What changes were proposed in this pull request?
Use `Utils.getSimpleName` to avoid hitting `Malformed class name` error in `NewInstance.doGenCode`.
### Why are the changes needed?
On older JDK versions (e.g. JDK8u), nested Scala classes may trigger `java.lang.Class.getSimpleName` to throw an `java.lang.InternalError: Malformed class name` error.
In this particular case, creating an `ExpressionEncoder` on such a nested Scala class would create a `NewInstance` expression under the hood, which will trigger the problem during codegen.
Similar to https://github.com/apache/spark/pull/29050, we should use Spark's `Utils.getSimpleName` utility function in place of `Class.getSimpleName` to avoid hitting the issue.
There are two other occurrences of `java.lang.Class.getSimpleName` in the same file, but they're safe because they're only guaranteed to be only used on Java classes, which don't have this problem, e.g.:
```scala
// Make a copy of the data if it's unsafe-backed
def makeCopyIfInstanceOf(clazz: Class[_ <: Any], value: String) =
s"$value instanceof ${clazz.getSimpleName}? ${value}.copy() : $value"
val genFunctionValue: String = lambdaFunction.dataType match {
case StructType(_) => makeCopyIfInstanceOf(classOf[UnsafeRow], genFunction.value)
case ArrayType(_, _) => makeCopyIfInstanceOf(classOf[UnsafeArrayData], genFunction.value)
case MapType(_, _, _) => makeCopyIfInstanceOf(classOf[UnsafeMapData], genFunction.value)
case _ => genFunction.value
}
```
The Unsafe-* family of types are all Java types, so they're okay.
### Does this PR introduce _any_ user-facing change?
Fixes a bug that throws an error when using `ExpressionEncoder` on some nested Scala types, otherwise no changes.
### How was this patch tested?
Added a test case to `org.apache.spark.sql.catalyst.encoders.ExpressionEncoderSuite`. It'll fail on JDK8u before the fix, and pass after the fix.

### What changes were proposed in this pull request?
Currently, the warehouse path gets fully qualified in the caller side for creating a database, table, partition, etc. An unqualified path is populated into Spark and Hadoop confs, which leads to inconsistent API behaviors. We should make it qualified ahead.
When the value is a relative path `spark.sql.warehouse.dir=lakehouse`, some behaviors become inconsistent, for example.
If the default database is absent at runtime, the app fails with
```java
Caused by: java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: file:./lakehouse

```
If the default database is present at runtime, the app can work with it, and if we create a database, it gets fully qualified, for example
```sql
spark-sql> create database test;
Time taken: 0.052 seconds
spark-sql> desc database test;

```
Another thing is that the log becomes nubilous, for example.
```logtalk

### What changes were proposed in this pull request?
Today, child expressions may be resolved based on "real" or metadata output attributes. We should prefer the real attribute during resolution if one exists.
### Why are the changes needed?
Today, attempting to resolve an expression when there is a "real" output attribute and a metadata attribute with the same name results in resolution failure. This is likely unexpected, as the user may not know about the metadata attribute.
### Does this PR introduce _any_ user-facing change?
Yes. Previously, the user would see an error message when resolving a column with the same name as a "real" output attribute and a metadata attribute as below:
```
org.apache.spark.sql.AnalysisException: Reference 'index' is ambiguous, could be: testcat.ns1.ns2.tableTwo.index, testcat.ns1.ns2.tableOne.index.; line 1 pos 71

at org.apache.spark.sql.catalyst.plans.logical.LogicalPlan.resolveChildren(LogicalPlan.scala:107)
```
Now, resolution succeeds and provides the "real" output attribute.

### What changes were proposed in this pull request?
Currently in `SpecificParquetRecordReaderBase` we use deprecated APIs in a few places from Parquet, such as `readFooter`, `ParquetInputSplit`, `new ParquetFileReader`, `filterRowGroups`, etc. This replaces these with the newer APIs. In specific this:
- Replaces `ParquetInputSplit` with `FileSplit`. We never use specific things in the former such as `rowGroupOffsets` so the swap is pretty simple.
- Removes `readFooter` calls by using `ParquetFileReader.open`
- Replace deprecated `ParquetFileReader` ctor with the newer API which takes `ParquetReadOptions`.
- Removes the unnecessary handling of case when `rowGroupOffsets` is not null. It seems this never happens.
### Why are the changes needed?
The aforementioned APIs were deprecated and is going to be removed at some point in future. This is to ensure better supportability.

### Why is this change being proposed?
This patch adds support for a new "product" aggregation function in `sql.functions` which multiplies-together all values in an aggregation group.
This is likely to be useful in statistical applications which involve combining probabilities, or financial applications that involve combining cumulative interest rates, but is also a versatile mathematical operation of similar status to `sum` or `stddev`. Other users [have noted](https://stackoverflow.com/questions/52991640/cumulative-product-in-spark) the absence of such a function in current releases of Spark.
This function is both much more concise than an expression of the form `exp(sum(log(...)))`, and avoids awkward edge-cases associated with some values being zero or negative, as well as being less computationally costly.
### Does this PR introduce _any_ user-facing change?
No - only adds new function.
### How was this patch tested?
Built-in tests have been added for the new `catalyst.expressions.aggregate.Product` class and its invocation via the (scala) `sql.functions.product` function. The latter, and the PySpark wrapper have also been manually tested in spark-shell and pyspark sessions. The SparkR wrapper is currently untested, and may need separate validation (I'm not an "R" user myself).
An illustration of the new functionality, within PySpark is as follows:
```
import pyspark.sql.functions as pf, pyspark.sql.window as pw
df = sqlContext.range(1, 17).toDF("x")
win = pw.Window.partitionBy(pf.lit(1)).orderBy(pf.col("x"))
df.withColumn("factorial", pf.product("x").over(win)).show(20, False)

In the `SQLConf` object, the `sqlConfEntries` map is globally synchronized (it is a Java `Collections.synchronizedMap`): any operation, including a get, will need to acquire the lock.
An example of this is calling the `DatatType.sameType` method. This will trigger a check on `SQLConf.get.caseSensitiveAnalysis`. So every time we compare two datatypes with sameType, we hit a lock.
To avoid having multiple tasks locking on this, a better approach would be to use a map that does not lock on read (like a `ConcurrentHashMap`). This map implementation does not lock on read, and on write it only locks the map partially. The only lock that happens is on write on the same map key.
### Why are the changes needed?
Multiple tasks performing any operation that directly or indirectly trigger a query to the `SQLConf.sqlConfEntries` map, will require acquiring a global lock on that map. Something as easy as calling `DataType.sameType(...)` would be locking on the global `sqlConfEntries` lock of the `Collections.synchronizedMap`.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
In the PR, I propose to generate unique attributes in the logical nodes of the `SHOW TABLES` command.
Also, this PR fixes similar issues in other logical nodes:
- ShowTableExtended
- ShowViews
- ShowTableProperties
- ShowFunctions
- ShowColumns
- ShowPartitions
- ShowNamespaces
### Why are the changes needed?
This fixes the issue which is demonstrated by the example below:
```scala
scala> val show1 = sql("SHOW TABLES IN ns1")
show1: org.apache.spark.sql.DataFrame = [namespace: string, tableName: string ... 1 more field]
scala> val show2 = sql("SHOW TABLES IN ns2")
show2: org.apache.spark.sql.DataFrame = [namespace: string, tableName: string ... 1 more field]
scala> show1.show
+---------+---------+-----------+
|namespace|tableName|isTemporary|
+---------+---------+-----------+
| ns1| tbl1| false|
+---------+---------+-----------+
scala> show2.show
+---------+---------+-----------+
|namespace|tableName|isTemporary|
+---------+---------+-----------+
| ns2| tbl2| false|
+---------+---------+-----------+
scala> show1.join(show2).where(show1("tableName") =!= show2("tableName")).show
org.apache.spark.sql.AnalysisException: Column tableName#17 are ambiguous. It's probably because you joined several Datasets together, and some of these Datasets are the same. This column points to one of the Datasets but Spark is unable to figure out which one. Please alias the Datasets with different names via `Dataset.as` before joining them, and specify the column using qualified name, e.g. `df.as("a").join(df.as("b"), $"a.id" > $"b.id")`. You can also set spark.sql.analyzer.failAmbiguousSelfJoin to false to disable this check.

```
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above works as expected:
```scala
scala> show1.join(show2).where(show1("tableName") =!= show2("tableName")).show
+---------+---------+-----------+---------+---------+-----------+
|namespace|tableName|isTemporary|namespace|tableName|isTemporary|

### What changes were proposed in this pull request?
In the PR, I propose to generate "stable" output attributes per the logical node of the `DESCRIBE TABLE` command.

sql(s"CREATE TABLE $tbl (c0 INT) USING _")
val description = sql(s"DESCRIBE TABLE $tbl")
description.drop("comment")
```
The `drop()` method fails with the error:

### What changes were proposed in this pull request?
This PR makes partition spec parsing respect case sensitive conf.
### Why are the changes needed?
When parsing the partition spec, Spark will call `org.apache.spark.sql.catalyst.parser.ParserUtils.checkDuplicateKeys` to check if there are duplicate partition column names in the list. But this method is always case sensitive and doesn't detect duplicate partition column names when using different cases.
### Does this PR introduce _any_ user-facing change?
Yep. This prevents users from writing incorrect queries such as `INSERT OVERWRITE t PARTITION (c='2', C='3') VALUES (1)` when they don't enable case sensitive conf.

### What changes were proposed in this pull request?
SPARK-33084 added the ability to use ivy coordinates with `SparkContext.addJar`. PR #29966 claims to mimic Hive behavior although I found a few cases where it doesn't
1) The default value of the transitive parameter is false, both in case of parameter not being specified in coordinate or parameter value being invalid. The Hive behavior is that transitive is [true if not specified](cb2ac3dcc6/ql/src/java/org/apache/hadoop/hive/ql/util/DependencyResolver.java (L169)) in the coordinate and [false for invalid values](cb2ac3dcc6/ql/src/java/org/apache/hadoop/hive/ql/util/DependencyResolver.java (L124)). Also, regardless of Hive, I think a default of true for the transitive parameter also matches [ivy's own defaults](https://ant.apache.org/ivy/history/2.5.0/ivyfile/dependency.html#_attributes).
2) The parameter value for transitive parameter is regarded as case-sensitive [based on the understanding](https://github.com/apache/spark/pull/29966#discussion_r547752259) that Hive behavior is case-sensitive. However, this is not correct, Hive [treats the parameter value case-insensitively](cb2ac3dcc6/ql/src/java/org/apache/hadoop/hive/ql/util/DependencyResolver.java (L122)).
I propose that we be compatible with Hive for these behaviors
### Why are the changes needed?
To make `ADD JAR` with ivy coordinates compatible with Hive's transitive behavior
### Does this PR introduce _any_ user-facing change?
The user-facing changes here are within master as the feature introduced in SPARK-33084 has not been released yet
1. Previously an ivy coordinate without `transitive` parameter specified did not resolve transitive dependency, now it does.
2. Previously an `transitive` parameter value was treated case-sensitively. e.g. `transitive=TRUE` would be treated as false as it did not match exactly `true`. Now it will be treated case-insensitively.
### How was this patch tested?
Modified existing unit tests to test new behavior

### What changes were proposed in this pull request?
I discovered from review discussion - https://github.com/apache/spark/pull/31630#discussion_r581774000 , that we can eliminate LEFT ANTI join (with no join condition) to empty relation, if the right side is known to be non-empty. So with AQE, this is doable similar to https://github.com/apache/spark/pull/29484 .
### Why are the changes needed?
This can help eliminate the join operator during logical plan optimization.
Before this PR, [left side physical plan `execute()` will be called](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/BroadcastNestedLoopJoinExec.scala#L192), so if left side is complicated (e.g. contain broadcast exchange operator), then some computation would happen. However after this PR, the join operator will be removed during logical plan, and nothing will be computed from left side. Potentially it can save resource for these kinds of query.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

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

### What changes were proposed in this pull request?
Preprocess the partition spec passed to the V1 `ALTER TABLE .. SET LOCATION` implementation `AlterTableSetLocationCommand`, and normalize the passed spec according to the partition columns w.r.t the case sensitivity flag **spark.sql.caseSensitive**.
### Why are the changes needed?
V1 `ALTER TABLE .. SET LOCATION` is case sensitive in fact, and doesn't respect the SQL config **spark.sql.caseSensitive** which is false by default, for instance:
```sql
spark-sql> CREATE TABLE tbl (id INT, part INT) PARTITIONED BY (part);
spark-sql> INSERT INTO tbl PARTITION (part=0) SELECT 0;
spark-sql> SHOW TABLE EXTENDED LIKE 'tbl' PARTITION (part=0);
Location: file:/Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/part=0
spark-sql> ALTER TABLE tbl ADD PARTITION (part=1);
spark-sql> SELECT * FROM tbl;
0 0
```

```
$ cp -r /Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/part=0 /Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/aaa
```
Set new location for the partition part=1:
```sql
spark-sql> ALTER TABLE tbl PARTITION (part=1) SET LOCATION '/Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/aaa';
spark-sql> SELECT * FROM tbl;
0 0
0 1
spark-sql> ALTER TABLE tbl ADD PARTITION (PART=2);
spark-sql> SELECT * FROM tbl;
0 0
0 1
```
Set location for a partition in the upper case:
```
$ cp -r /Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/part=0 /Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/bbb
```
```sql
spark-sql> ALTER TABLE tbl PARTITION (PART=2) SET LOCATION '/Users/maximgekk/proj/set-location-case-sense/spark-warehouse/tbl/bbb';
Error in query: Partition spec is invalid. The spec (PART) must match the partition spec (part) defined in table '`default`.`tbl`'
```
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the command above works as expected:

Rename the execution node `AlterTableRecoverPartitionsCommand` for the commands:
- `MSCK REPAIR TABLE table [{ADD|DROP|SYNC} PARTITIONS]`
- `ALTER TABLE table RECOVER PARTITIONS`
to `RepairTableCommand`.
### Why are the changes needed?
1. After the PR https://github.com/apache/spark/pull/31499, `ALTER TABLE table RECOVER PARTITIONS` is equal to `MSCK REPAIR TABLE table ADD PARTITIONS`. And mapping of the generic command `MSCK REPAIR TABLE` to the more specific execution node `AlterTableRecoverPartitionsCommand` can confuse devs in the future.
2. `ALTER TABLE table RECOVER PARTITIONS` does not support any options/extensions. So, additional parameters `enableAddPartitions` and `enableDropPartitions` in `AlterTableRecoverPartitionsCommand` confuse as well.

No because this is internal API.

### What changes were proposed in this pull request?
Some of the built-in JDBC connection providers are changing the JVM security context to do the authentication which is fine. The problematic part is that executors can be reused by another query. The following situation leads to incorrect behaviour:
* Query1 opens JDBC connection and changes JVM security context in Executor1
* Query2 tries to open JDBC connection but it realizes there is already an entry for that DB type in Executor1
* Query2 is not changing JVM security context and uses Query1 keytab and principal
* Query2 fails with authentication error
In this PR I've changed to code such a way that JVM security context is changed all the time but only temporarily until the connection built-up and then rolled back. Since `getConnection` is synchronised with `SecurityConfigurationLock` it ends-up in correct behaviour without any race.
### Why are the changes needed?
Incorrect JVM security context handling.

### What changes were proposed in this pull request?
I found out during code review of https://github.com/apache/spark/pull/31567#discussion_r577379572, where we can push down limit to the left side of LEFT SEMI and LEFT ANTI join, if the join condition is empty.
Why it's safe to push down limit:
The semantics of LEFT SEMI join without condition:
(1). if right side is non-empty, output all rows from left side.
(2). if right side is empty, output nothing.
The semantics of LEFT ANTI join without condition:
(1). if right side is non-empty, output nothing.
(2). if right side is empty, output all rows from left side.
With the semantics of output all rows from left side or nothing (all or nothing), it's safe to push down limit to left side.
NOTE: LEFT SEMI / LEFT ANTI join with non-empty condition is not safe for limit push down, because output can be a portion of left side rows.
Reference: physical operator implementation for LEFT SEMI / LEFT ANTI join without condition - https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/BroadcastNestedLoopJoinExec.scala#L200-L204 .
### Why are the changes needed?
Better performance. Save CPU and IO for these joins, as limit being pushed down before join.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Added unit test in `LimitPushdownSuite.scala` and `SQLQuerySuite.scala`.

### What changes were proposed in this pull request?
This PR proposes to make `CreateViewStatement.child` to be `LogicalPlan`'s `children` so that it's resolved in the analyze phase.
### Why are the changes needed?
Currently, the `CreateViewStatement.child` is resolved when the create view command runs, which is inconsistent with other plan resolutions. For example, you may see the following in the physical plan:
```
== Physical Plan ==
Execute CreateViewCommand (1)
+- CreateViewCommand (2)
+- Project (4)
+- UnresolvedRelation (3)
```
### Does this PR introduce _any_ user-facing change?
Yes. For the example, you will now see the resolved plan:
```
== Physical Plan ==
Execute CreateViewCommand (1)
+- CreateViewCommand (2)
+- Project (5)
+- SubqueryAlias (4)
+- LogicalRelation (3)
```
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
In Spark ANSI mode, the type coercion rules are based on the type precedence lists of the input data types.
As per the section "Type precedence list determination" of "ISO/IEC 9075-2:2011
Information technology — Database languages - SQL — Part 2: Foundation (SQL/Foundation)", the type precedence lists of primitive data types are as following:
- Byte: Byte, Short, Int, Long, Decimal, Float, Double
- Short: Short, Int, Long, Decimal, Float, Double
- Int: Int, Long, Decimal, Float, Double
- Long: Long, Decimal, Float, Double
- Decimal: Any wider Numeric type
- Float: Float, Double
- Double: Double
- String: String
- Date: Date, Timestamp
- Timestamp: Timestamp
- Binary: Binary
- Boolean: Boolean
- Interval: Interval
As for complex data types, Spark will determine the precedent list recursively based on their sub-types.
With the definition of type precedent list, the general type coercion rules are as following:
- Data type S is allowed to be implicitly cast as type T iff T is in the precedence list of S
- Comparison is allowed iff the data type precedence list of both sides has at least one common element. When evaluating the comparison, Spark casts both sides as the tightest common data type of their precedent lists.
- There should be at least one common data type among all the children's precedence lists for the following operators. The data type of the operator is the tightest common precedent data type.
```
In, Except(odd), Intersect, Greatest, Least, Union, If, CaseWhen, CreateArray, Array Concat,Sequence, MapConcat, CreateMap
```
- For complex types (struct, array, map), Spark recursively looks into the element type and applies the rules above. If the element nullability is converted from true to false, add runtime null check to the elements.
Note: this new type coercion system will allow implicit converting String type literals as other primitive types, in case of breaking too many existing Spark SQL queries. This is a special rule and it is not from the ANSI SQL standard.
### Why are the changes needed?
The current type coercion rules are complex. Also, they are very hard to describe and understand. For details please refer the attached documentation "Default Type coercion rules of Spark"
[Default Type coercion rules of Spark.pdf](https://github.com/apache/spark/files/5874362/Default.Type.coercion.rules.of.Spark.pdf)
This PR is to create a new and strict type coercion system under ANSI mode. The rules are simple and clean, so that users can follow them easily
### Does this PR introduce _any_ user-facing change?
Yes, new implicit cast syntax rules in ANSI mode. All the details are in the first section of this description.
### How was this patch tested?
Unit tests

### What changes were proposed in this pull request?
Implement the v2 execution node for the `TRUNCATE TABLE` command.
### Why are the changes needed?
To have feature parity with DS v1, and support truncation of v2 tables.
### Does this PR introduce _any_ user-facing change?
Yes
### How was this patch tested?
By running the unified tests for v1 and v2 tables:
```
$ build/sbt -Phive -Phive-thriftserver "test:testOnly *TruncateTableSuite"
```

### What changes were proposed in this pull request?
In the PR, I propose to extend the `MSCK REPAIR TABLE` command, and support new options `{ADD|DROP|SYNC} PARTITIONS`. In particular:
1. Extend the logical node `RepairTable`, and add two new flags `enableAddPartitions` and `enableDropPartitions`.
2. Add similar flags to the v1 execution node `AlterTableRecoverPartitionsCommand`
3. Add new method `dropPartitions()` to `AlterTableRecoverPartitionsCommand` which drops partitions from the catalog if their locations in the file system don't exist.
4. Updated public docs about the `MSCK REPAIR TABLE` command:

Closes#31097
### Why are the changes needed?
- The changes allow to recover tables with removed partitions. The example below portraits the problem:
```sql
spark-sql> create table tbl2 (col int, part int) partitioned by (part);
spark-sql> insert into tbl2 partition (part=1) select 1;
spark-sql> insert into tbl2 partition (part=0) select 0;
spark-sql> show table extended like 'tbl2' partition (part = 0);
default tbl2 false Partition Values: [part=0]
Location: file:/Users/maximgekk/proj/apache-spark/spark-warehouse/tbl2/part=0
...
```
Remove the partition (part = 0) from the filesystem:
```
$ rm -rf /Users/maximgekk/proj/apache-spark/spark-warehouse/tbl2/part=0
```
Even after recovering, we cannot query the table:
```sql
spark-sql> msck repair table tbl2;
spark-sql> select * from tbl2;
21/01/08 22:49:13 ERROR SparkSQLDriver: Failed in [select * from tbl2]
org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: file:/Users/maximgekk/proj/apache-spark/spark-warehouse/tbl2/part=0
```
- To have feature parity with Hive: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-RecoverPartitions(MSCKREPAIRTABLE)
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, we can query recovered table:
```sql
spark-sql> msck repair table tbl2 sync partitions;
spark-sql> select * from tbl2;
1 1
spark-sql> show partitions tbl2;
part=1
```
### How was this patch tested?
- By running the modified test suite:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *MsckRepairTableParserSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *PlanResolutionSuite"

$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableRecoverPartitionsParallelSuite"
```
- Added unified v1 and v2 tests for `MSCK REPAIR TABLE`:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *MsckRepairTableSuite"
```
