### What changes were proposed in this pull request?
This is followup from https://github.com/apache/spark/pull/29342, where to do two things:
* Per https://github.com/apache/spark/pull/29342#discussion_r470153323, change from java `HashSet` to spark in-house `OpenHashSet` to track matched rows for non-unique join keys. I checked `OpenHashSet` implementation which is built from a key index (`OpenHashSet._bitset` as `BitSet`) and key array (`OpenHashSet._data` as `Array`). Java `HashSet` is built from `HashMap`, which stores value in `Node` linked list and by theory should have taken more memory than `OpenHashSet`. Reran the same benchmark query used in https://github.com/apache/spark/pull/29342, and verified the query has similar performance here between `HashSet` and `OpenHashSet`.
* Track metrics of the extra data structure `BitSet`/`OpenHashSet` for full outer SHJ. This depends on above thing, because there seems no easy way to get java `HashSet` memory size.
### Why are the changes needed?
To better surface the memory usage for full outer SHJ more accurately.
This can help users/developers to debug/improve full outer SHJ.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
Remove the YEAR, MONTH, DAY, HOUR, MINUTE, SECOND keywords. They are not useful in the parser, as we need to support plural like YEARS, so the parser has to accept the general identifier as interval unit anyway.
### Why are the changes needed?
These keywords are reserved in ANSI. If Spark has these keywords, then they become reserved under ANSI mode. This makes Spark not able to run TPCDS queries as they use YEAR as alias name.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Added `TPCDSQueryANSISuite`, to make sure Spark with ANSI mode can run TPCDS queries.

### What changes were proposed in this pull request?
Fixed `CrossValidatorModel.copy()` so that it correctly calls `.copy()` on the models instead of lists of models.
### Why are the changes needed?
`copy()` was first changed in #29445 . The issue was found in CI of #29524 and fixed. This PR introduces the exact same change so that `CrossValidatorModel.copy()` and its related tests are aligned in branch `master` and branch `branch-3.0`.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Updated `test_copy` to make sure `copy()` is called on models instead of lists of models.

### What changes were proposed in this pull request?
Remove the assertion in ParquetSchemaConverter that the parquet mapKey field must be PrimitiveType.
### Why are the changes needed?
There is a parquet file in the attachment of [SPARK-32639](https://issues.apache.org/jira/browse/SPARK-32639), and the MessageType recorded in the file is:
```
message parquet_schema {
optional group value (MAP) {
repeated group key_value {
required group key {
optional binary first (UTF8);
optional binary middle (UTF8);
optional binary last (UTF8);
}
optional binary value (UTF8);
}
}
}
```
Use `spark.read.parquet("000.snappy.parquet")` to read the file. Spark will throw an exception when converting Parquet MessageType to Spark SQL StructType:
> AssertionError(Map key type is expected to be a primitive type, but found...)
Use `spark.read.schema("value MAP<STRUCT<first:STRING, middle:STRING, last:STRING>, STRING>").parquet("000.snappy.parquet")` to read the file, spark returns the correct result .
According to the parquet project document (https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#maps), the mapKey in the parquet format does not need to be a primitive type.
Note: This parquet file is not written by spark, because spark will write additional sparkSchema string information in the parquet file. When Spark reads, it will directly use the additional sparkSchema information in the file instead of converting Parquet MessageType to Spark SQL StructType.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
This PR proposes to add a specific `AQEOptimizer` for the `AdaptiveSparkPlanExec` instead of implementing an anonymous `RuleExecutor`. At the same time, this PR also adds the configuration `spark.sql.adaptive.optimizer.excludedRules`, which follows the same pattern of `Optimizer`, to make the `AQEOptimizer` more flexible for users and developers.
### Why are the changes needed?
Currently, `AdaptiveSparkPlanExec` has implemented an anonymous `RuleExecutor` to apply the AQE optimize rules on the plan. However, the anonymous class usually could be inconvenient to maintain and extend for the long term.
### Does this PR introduce _any_ user-facing change?
No.

### What changes were proposed in this pull request?
This PR changes key data types check in `HashJoin` to use `sameType`.
### Why are the changes needed?
Looks at the resolving condition of `SetOperation`, it requires only each left data types should be `sameType` as the right ones. Logically the `EqualTo` expression in equi-join, also requires only left data type `sameType` as right data type. Then `HashJoin` requires left keys data type exactly the same as right keys data type, looks not reasonable.
It makes inconsistent results when doing `except` between two dataframes.
If two dataframes don't have nested fields, even their field nullable property different, `HashJoin` passes the key type check because it checks field individually so field nullable property is ignored.
If two dataframes have nested fields like struct, `HashJoin` fails the key type check because now it compare two struct types and nullable property now affects.
### Does this PR introduce _any_ user-facing change?
Yes. Making consistent `except` operation between dataframes.
### How was this patch tested?

The current documentation states that the default value of spark.hadoop.mapreduce.fileoutputcommitter.algorithm.version is 1 which is not entirely true since this configuration isn't set anywhere in Spark but rather inherited from the Hadoop FileOutputCommitter class.
### What changes were proposed in this pull request?
I'm submitting this change, to clarify that the default value will entirely depend on the Hadoop version of the runtime environment.
### Why are the changes needed?
An application would end up using algorithm version 1 on certain environments but without any changes the same exact application will use version 2 on environments running Hadoop 3.0 and later. This can have pretty bad consequences in certain scenarios, for example, two tasks can partially overwrite their output if speculation is enabled. Also, please refer to the following JIRA:
https://issues.apache.org/jira/browse/MAPREDUCE-7282
### Does this PR introduce _any_ user-facing change?
Yes. Configuration page content was modified where previously we explicitly highlighted that the default version for the FileOutputCommitter algorithm was v1, this now has changed to "Dependent on environment" with additional information in the description column to elaborate.

### What changes were proposed in this pull request?
We are using an older version of Bootstrap (v. 2.1.0) for the online documentation site. Bootstrap 2.x was moved to EOL in Aug 2013 and Bootstrap 3.x was moved to EOL in July 2019 (https://github.com/twbs/release). Older versions of Bootstrap are also getting flagged in security scans for various CVEs:
https://snyk.io/vuln/SNYK-JS-BOOTSTRAP-72889https://snyk.io/vuln/SNYK-JS-BOOTSTRAP-173700https://snyk.io/vuln/npm:bootstrap:20180529https://snyk.io/vuln/npm:bootstrap:20160627
I haven't validated each CVE, but it would probably be good practice to resolve any potential issues and get on a supported release.
The bad news is that there have been quite a few changes between Bootstrap 2 and Bootstrap 4. I've tried updating the library, refactoring/tweaking the CSS and JS to maintain a similar appearance and functionality, and testing the documentation. This is a fairly large change so I'm sure additional testing and fixes will be needed.
### How was this patch tested?
This has been manually tested, but as there is a lot of documentation it is possible issues were missed. Additional testing and feedback is welcomed. If it appears a whole section was missed let me know and I'll take a pass at addressing that section.

### What changes were proposed in this pull request?
This is a follow up PR to #29328 to apply the same constraint where `path` option cannot coexist with path parameter to `DataFrameWriter.save()`, `DataStreamReader.load()` and `DataStreamWriter.start()`.
### Why are the changes needed?
The current behavior silently overwrites the `path` option if path parameter is passed to `DataFrameWriter.save()`, `DataStreamReader.load()` and `DataStreamWriter.start()`.
For example,
```
Seq(1).toDF.write.option("path", "/tmp/path1").parquet("/tmp/path2")
```
will write the result to `/tmp/path2`.
### Does this PR introduce _any_ user-facing change?
Yes, if `path` option coexists with path parameter to any of the above methods, it will throw `AnalysisException`:
```
scala> Seq(1).toDF.write.option("path", "/tmp/path1").parquet("/tmp/path2")
org.apache.spark.sql.AnalysisException: There is a 'path' option set and save() is called with a path parameter. Either remove the path option, or call save() without the parameter. To ignore this check, set 'spark.sql.legacy.pathOptionBehavior.enabled' to 'true'.;
```
The user can restore the previous behavior by setting `spark.sql.legacy.pathOptionBehavior.enabled` to `true`.

### What changes were proposed in this pull request?
The decommissioning state is a bit fragment across two places in the TaskSchedulerImpl:
https://github.com/apache/spark/pull/29014/ stored the incoming decommission info messages in TaskSchedulerImpl.executorsPendingDecommission.
While https://github.com/apache/spark/pull/28619/ was storing just the executor end time in the map TaskSetManager.tidToExecutorKillTimeMapping (which in turn is contained in TaskSchedulerImpl).
While the two states are not really overlapping, it's a bit of a code hygiene concern to save this state in two places.
With https://github.com/apache/spark/pull/29422, TaskSchedulerImpl is emerging as the place where all decommissioning book keeping is kept within the driver. So consolidate the information in _tidToExecutorKillTimeMapping_ into _executorsPendingDecommission_.
However, in order to do so, we need to walk away from keeping the raw ExecutorDecommissionInfo messages and instead keep another class ExecutorDecommissionState. This decoupling will allow the RPC message class ExecutorDecommissionInfo to evolve independently from the book keeping ExecutorDecommissionState.
### Why are the changes needed?
This is just a code cleanup. These two features were added independently and its time to consolidate their state for good hygiene.

Spark's CSV source can optionally ignore lines starting with a comment char. Some code paths check to see if it's set before applying comment logic (i.e. not set to default of `\0`), but many do not, including the one that passes the option to Univocity. This means that rows beginning with a null char were being treated as comments even when 'disabled'.

This is a bug of the doc that we inherited from JDK https://bugs.openjdk.java.net/browse/JDK-8169482
The SimpleDateFormatter(**F Day of week in month**) we used in 2.x and the DatetimeFormatter(**F week-of-month**) we use now both have the opposite meanings to what they declared in the java docs. And unfortunately, this also leads to silent data change in Spark too.
The `week-of-month` is actually the pattern `W` in DatetimeFormatter, which is banned to use in Spark 3.x.
If we want to keep pattern `F`, we need to accept the behavior change with proper migration guide and fix the doc in Spark

### What changes were proposed in this pull request?
There is a bug in the way the optimizer rule in `SimplifyExtractValueOps` is currently written in master branch which yields incorrect results in scenarios like the following:
```
sql("SELECT CAST(NULL AS struct<a:int,b:int>) struct_col")
.select($"struct_col".withField("d", lit(4)).getField("d").as("d"))
// currently returns this:
+---+
|d |
+---+
|4 |
+---+
// when in fact it should return this:
+----+
|d |
+----+
|null|
+----+
```
The changes in this PR will fix this bug.
### Why are the changes needed?
To fix the aforementioned bug. Optimizer rules should improve the performance of the query but yield exactly the same results.
### Does this PR introduce _any_ user-facing change?
Yes, this bug will no longer occur.
That said, this isn't something to be concerned about as this bug was introduced in Spark 3.1 and Spark 3.1 has yet to be released.
### How was this patch tested?
Unit tests were added. Jenkins must pass them.

### What changes were proposed in this pull request?
This PR proposes to fix ORC predicate pushdown under case-insensitive analysis case. The field names in pushed down predicates don't need to match in exact letter case with physical field names in ORC files, if we enable case-insensitive analysis.
This is re-submitted for #29457. Because #29457 has a hive-1.2 error and there were some tests failed with hive-1.2 profile at the same time, #29457 was reverted to unblock others.
### Why are the changes needed?
Currently ORC predicate pushdown doesn't work with case-insensitive analysis. A predicate "a < 0" cannot pushdown to ORC file with field name "A" under case-insensitive analysis.
But Parquet predicate pushdown works with this case. We should make ORC predicate pushdown work with case-insensitive analysis too.
### Does this PR introduce _any_ user-facing change?
Yes, after this PR, under case-insensitive analysis, ORC predicate pushdown will work.
### How was this patch tested?
Unit tests.

### Why are the changes needed?
This brings the Scala/Python catalog APIs a bit closer to what's already possible via SQL.
### Does this PR introduce any user-facing change?
Yes, it adds a new parameter to `Catalog.createTable()`.

### What changes were proposed in this pull request?
Change to use `dataTypes.foreach` instead of get the element use specified index in `def this(dataTypes: Seq[DataType]) `constructor of `SpecificInternalRow` because the random access performance is unsatisfactory if the input argument not a `IndexSeq`.
This pr followed srowen's advice.
### Why are the changes needed?
I found that SPARK-32550 had some negative impact on performance, the typical cases is "deterministic cardinality estimation" in `HyperLogLogPlusPlusSuite` when rsd is 0.001, we found the code that is significantly slower is line 41 in `HyperLogLogPlusPlusSuite`： `new SpecificInternalRow(hll.aggBufferAttributes.map(_.dataType)) `
08b951b1cb/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/aggregate/HyperLogLogPlusPlusSuite.scala (L40-L44)
The size of "hll.aggBufferAttributes" in this case is 209716, the results of comparison before and after spark-32550 merged are as follows, The unit is ns:

### What changes were proposed in this pull request?
As discussed in https://github.com/apache/spark/pull/29491#discussion_r474451282 and in SPARK-32686, this PR un-deprecates Spark's ability to infer a DataFrame schema from a list of dictionaries. The ability is Pythonic and matches functionality offered by Pandas.
### Why are the changes needed?
This change clarifies to users that this behavior is supported and is not going away in the near future.
### Does this PR introduce _any_ user-facing change?
Yes. There used to be a `UserWarning` for this, but now there isn't.
### How was this patch tested?
I tested this manually.

### What changes were proposed in this pull request?
This PR proposes to make the behavior consistent for the `path` option when loading dataframes with a single path (e.g, `option("path", path).format("parquet").load(path)` vs. `option("path", path).parquet(path)`) by disallowing `path` option to coexist with `load`'s path parameters.
### Why are the changes needed?
The current behavior is inconsistent:
```scala
scala> Seq(1).toDF.write.mode("overwrite").parquet("/tmp/test")
scala> spark.read.option("path", "/tmp/test").format("parquet").load("/tmp/test").show
+-----+
|value|
+-----+
| 1|
+-----+
scala> spark.read.option("path", "/tmp/test").parquet("/tmp/test").show
+-----+
|value|
+-----+
| 1|
| 1|
+-----+
```
### Does this PR introduce _any_ user-facing change?
Yes, now if the `path` option is specified along with `load`'s path parameters, it would fail:
```scala
scala> Seq(1).toDF.write.mode("overwrite").parquet("/tmp/test")
scala> spark.read.option("path", "/tmp/test").format("parquet").load("/tmp/test").show
org.apache.spark.sql.AnalysisException: There is a path option set and load() is called with path parameters. Either remove the path option or move it into the load() parameters.;

In order to produce consistent results from SizeEstimator the tests
override some system properties that are used during SizeEstimator
initialization. However there were several places where either the
compressed references property wasn't set or the system properties
were set but the SizeEstimator not re-initialized.
This caused failures when running the tests with a large heap build
of OpenJ9 because it does not use compressed references unlike most
environments.
### What changes were proposed in this pull request?
Initialize SizeEstimator class explicitly in the tests where required to avoid relying on a particular environment.
### Why are the changes needed?
Test failures can be seen when compressed references are disabled (e.g. using an OpenJ9 large heap build or Hotspot with a large heap).
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Tests run on machine running OpenJ9 large heap build.

### What changes were proposed in this pull request?
For broadcast hash join and shuffled hash join, whenever the build side hashed relation turns out to be empty. We don't need to execute stream side plan at all, and can return an empty iterator (for inner join and left semi join), because we know for sure that none of stream side rows can be outputted as there's no match.
### Why are the changes needed?
A very minor optimization for rare use case, but in case build side turns out to be empty, we can leverage it to short-cut stream side to save CPU and IO.
Example broadcast hash join query similar to `JoinBenchmark` with empty hashed relation:
```
def broadcastHashJoinLongKey(): Unit = {
val N = 20 << 20
val M = 1 << 16
val dim = broadcast(spark.range(0).selectExpr("id as k", "cast(id as string) as v"))
codegenBenchmark("Join w long", N) {
val df = spark.range(N).join(dim, (col("id") % M) === col("k"))
assert(df.queryExecution.sparkPlan.find(_.isInstanceOf[BroadcastHashJoinExec]).isDefined)
df.noop()
}
}
```
Comparing wall clock time for enabling and disabling this PR (for non-codegen code path). Seeing like 8x improvement.

It fixes failures of `HiveSerDeReadWriteSuite` with the profile `hive-1.2`. In that case, the parent class `DateWritable` has different implementation before the commit to Hive da3ed68eda. In particular, `get()` calls `new Date(daysToMillis(daysSinceEpoch))` instead of overrided `def get(doesTimeMatter: Boolean): Date` in the child class.
