### What changes were proposed in this pull request?
In the PR, I propose to update the Spark SQL guide about the SQL configs that are related to datetime rebasing:
- spark.sql.parquet.int96RebaseModeInWrite
- spark.sql.parquet.datetimeRebaseModeInWrite
- spark.sql.parquet.int96RebaseModeInRead
- spark.sql.parquet.datetimeRebaseModeInRead
- spark.sql.avro.datetimeRebaseModeInWrite
- spark.sql.avro.datetimeRebaseModeInRead
Parquet options added by #31489:
- datetimeRebaseMode
- int96RebaseMode
and Avro options added by #31529:
- datetimeRebaseMode

### Why are the changes needed?
The config exists for enough time. We can deprecate it, and recommend users to use `.format("avro")` instead.
### Does this PR introduce _any_ user-facing change?
Should not except of the warning with the recommendation to use the `avro` format.

### What changes were proposed in this pull request?
Improving the documentation and release process by pinning Jekyll version by Gemfile and Bundler.
Some files and their responsibilities within this PR:
- `docs/.bundle/config` is used to specify a directory "docs/.local_ruby_bundle" which will be used as destination to install the ruby packages into instead of the global one which requires root access
- `docs/Gemfile` is specifying the required Jekyll version and other top level gem versions
- `docs/Gemfile.lock` is generated by the "bundle install". This file contains the exact resolved versions of all the gems including the top level gems and all the direct and transitive dependencies of those gems. When this file is generated it contains a platform related section "PLATFORMS" (in my case after the generation it was "universal-darwin-19"). Still this file must be under version control as when the version of a gem does not fit to the one specified in `Gemfile` an error comes (i.e. if the `Gemfile.lock` was generated for Jekyll 4.1.0 and its version is updated in the `Gemfile` to 4.2.0 then it triggers the error: "The bundle currently has jekyll locked at 4.1.0."). This is solution is also suggested officially in [its documentation](https://bundler.io/rationale.html#checking-your-code-into-version-control). To get rid of the specific platform (like "universal-darwin-19") first we have to add "ruby" as platform [which means this should work on every platform where Ruby runs](https://guides.rubygems.org/what-is-a-gem/)) by running "bundle lock --add-platform ruby" then the specific platform can be removed by "bundle lock --remove-platform universal-darwin-19".
After this the correct process to update Jekyll version is the following:
1. update the version in `Gemfile`
2. run "bundle update" which updates the `Gemfile.lock`
3. commit both files
This process for version update is tested for details please check the testing section.
### Why are the changes needed?
Using different Jekyll versions can generate different output documents.
This PR standardize the process.
### Does this PR introduce _any_ user-facing change?
No, assuming the release was done via docker by using `do-release-docker.sh`.
In that case there should be no difference at all as the same Jekyll version is specified in the Gemfile.
### How was this patch tested?
#### Testing document generation
Doc generation step was triggered via the docker release:
```
$ ./do-release-docker.sh -d ~/working -n -s docs

#### Testing Jekyll (or other gem) update
First locally I reverted Jekyll to 4.1.0:
```
$ rm Gemfile.lock
$ rm -rf .local_ruby_bundle
# edited Gemfile to use version 4.1.0
$ cat Gemfile
source "https://rubygems.org"
gem "jekyll", "4.1.0"
gem "rouge", "3.26.0"
gem "jekyll-redirect-from", "0.16.0"
gem "webrick", "1.7"
$ bundle install
...
```
Testing Jekyll version before the update:
```
$ bundle exec jekyll --version
jekyll 4.1.0
```
Imitating Jekyll update coming from git by reverting my local changes:
```
$ git checkout Gemfile
Updated 1 path from the index
$ cat Gemfile
source "https://rubygems.org"
gem "jekyll", "4.2.0"
gem "rouge", "3.26.0"
gem "jekyll-redirect-from", "0.16.0"
gem "webrick", "1.7"
$ git checkout Gemfile.lock
Updated 1 path from the index
```
Run the install:
```
$ bundle install
...
```
Checking the updated Jekyll version:
```
$ bundle exec jekyll --version
jekyll 4.2.0
```

### What changes were proposed in this pull request?
This PR adds the following metrics to track executor remove reasons during dynamic allocation:
- `numberExecutorsGracefullyDecommissioned`: number of executors which reached the finished decommissioning state and shut itself down cleanly
- `numberExecutorsDecommissionUnfinished`: executors which requested to decommission but they stopped without reaching the finished decommissioning state
- `numberExecutorsKilledByDriver`: executors killed by the driver (requested to stop)
- `numberExecutorsExitedUnexpectedly`: executors exited without driver request
### Why are the changes needed?
For supporting monitoring of dynamic allocation better with these metrics.
### Does this PR introduce _any_ user-facing change?
Yes. The new metrics will be available for monitoring.
### How was this patch tested?
With unit and integration tests.
Finally manually checked the new metrics in jconsole:

### What changes were proposed in this pull request?
Move the datetime rebase SQL configs from the `legacy` namespace by:
1. Renaming of the existing rebase configs like `spark.sql.legacy.parquet.datetimeRebaseModeInRead` -> `spark.sql.parquet.datetimeRebaseModeInRead`.
2. Add the legacy configs as alternatives
3. Deprecate the legacy rebase configs.
### Why are the changes needed?
The rebasing SQL configs like `spark.sql.legacy.parquet.datetimeRebaseModeInRead` can be used not only for migration from previous Spark versions but also to read/write datatime columns saved by other systems/frameworks/libs. So, the configs shouldn't be considered as legacy configs.
### Does this PR introduce _any_ user-facing change?
Should not. Users will see a warning if they still use one of the legacy configs.
### How was this patch tested?
1. Manually checking new configs:
```scala
scala> spark.conf.get("spark.sql.parquet.datetimeRebaseModeInRead")
res0: String = EXCEPTION
scala> spark.conf.set("spark.sql.legacy.parquet.datetimeRebaseModeInRead", "LEGACY")
21/02/17 14:57:10 WARN SQLConf: The SQL config 'spark.sql.legacy.parquet.datetimeRebaseModeInRead' has been deprecated in Spark v3.2 and may be removed in the future. Use 'spark.sql.parquet.datetimeRebaseModeInRead' instead.
scala> spark.conf.get("spark.sql.parquet.datetimeRebaseModeInRead")
res2: String = LEGACY
```
2. By running a datetime rebasing test suite:
```
$ build/sbt "test:testOnly *ParquetRebaseDatetimeV1Suite"
```

### What changes were proposed in this pull request?
This PR changes the type mapping for `money` and `money[]` types for PostgreSQL.
Currently, those types are tried to convert to `DoubleType` and `ArrayType` of `double` respectively.
But the JDBC driver seems not to be able to handle those types properly.
https://github.com/pgjdbc/pgjdbc/issues/100https://github.com/pgjdbc/pgjdbc/issues/1405
Due to these issue, we can get the error like as follows.
money type.
```

```
For money type, a known workaround is to treat it as string so this PR do it.
For money[], however, there is no reasonable workaround so this PR remove the support.
### Why are the changes needed?
This is a bug.
### Does this PR introduce _any_ user-facing change?
Yes. As of this PR merged, money type is mapped to `StringType` rather than `DoubleType` and the support for money[] is stopped.
For money type, if the value is less than one thousand, `$100.00` for instance, it works without this change so I also updated the migration guide because it's a behavior change for such small values.
On the other hand, money[] seems not to work with any value but mentioned in the migration guide just in case.
### How was this patch tested?
New test.

### What changes were proposed in this pull request?
This PR introduces a new protected method in `SparkFunSuite` which is only called when the test failed and can be used to collect logs for failed test. By this PR it is implemented in the Kubernetes tests by `KubernetesSuite` class where it collects all the POD logs and logs them out.
This unfortunately cannot be realized with a simple "after" method as in the "after" method the test outcome is not available.
Moreover this PR removes the `appLocator` as a method argument as `appLocator` is available as a member variable.
### Why are the changes needed?
Currently both the driver and executors logs are lost.
In [developer-tools](https://spark.apache.org/developer-tools.html) there is a hint:
"Getting logs from the pods and containers directly is an exercise left to the reader."
But when the test is executed by Jenkins and a failure happened we really need the POD logs to analyze problem.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
By integration testing. I have checked what would happen if one test fails, the output would be:

### What changes were proposed in this pull request?
Modify `RandomDataGenerator.forType()` to allow generation of dates/timestamps that are valid in both Julian and Proleptic Gregorian calendars. Currently, the function can produce a date (for example `1582-10-06`) which is valid in the Proleptic Gregorian calendar. Though it cannot be saved to ORC files AS IS since ORC format (ORC libs in fact) assumes Julian calendar. So, Spark shifts `1582-10-06` to the next valid date `1582-10-15` while saving it to ORC files. And as a consequence of that, the test fails because it compares original date `1582-10-06` and the date `1582-10-15` loaded back from the ORC files.
In this PR, I propose to generate valid dates/timestamps in both calendars for ORC datasource till SPARK-34440 is resolved.

To improve user experience with Spark SQL. Before the changes, the error message recommends to set SQL configs but the configs cannot help in the some situations (see the PRs for more details).
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the error message is:
_org.apache.spark.SparkUpgradeException: You may get a different result due to the upgrading of Spark 3.0: reading dates before 1582-10-15 or timestamps before 1900-01-01T00:00:00Z from Parquet files can be ambiguous, as the files may be written by Spark 2.x or legacy versions of Hive, which uses a legacy hybrid calendar that is different from Spark 3.0+'s Proleptic Gregorian calendar. See more details in SPARK-31404. You can set the SQL config 'spark.sql.legacy.parquet.datetimeRebaseModeInRead' or the datasource option 'datetimeRebaseMode' to 'LEGACY' to rebase the datetime values w.r.t. the calendar difference during reading. To read the datetime values as it is, set the SQL config 'spark.sql.legacy.parquet.datetimeRebaseModeInRead' or the datasource option 'datetimeRebaseMode' to 'CORRECTED'._

We have a use case in which we read a huge table in Avro format. About 30k columns.
using the default Hive reader - `AvroGenericRecordReader` it is just hangs forever. after 4 hours not even one task has finished.
We tried instead to use `spark.read.format("com.databricks.spark.avro").load(..)` but we failed on:
```
org.apache.spark.sql.AnalysisException: Found duplicate column(s) in the data schema
..
at org.apache.spark.sql.util.SchemaUtils$.checkColumnNameDuplication(SchemaUtils.scala:85)
at org.apache.spark.sql.util.SchemaUtils$.checkColumnNameDuplication(SchemaUtils.scala:67)
at org.apache.spark.sql.execution.datasources.DataSource.resolveRelation(DataSource.scala:421)
at org.apache.spark.sql.DataFrameReader.loadV1Source(DataFrameReader.scala:239)
at org.apache.spark.sql.DataFrameReader.load(DataFrameReader.scala:227)
at org.apache.spark.sql.DataFrameReader.load(DataFrameReader.scala:174)
... 53 elided
```
because files schema contain duplicate column names (when considering case-insensitive).
So we wanted to provide a user schema with non-duplicated fields, but the schema is huge. a few MBs. it is not practical to provide it in json format.
So we patched spark-avro to be able to get also `avroSchemaUrl` in addition to `avroSchema` and it worked perfectly.

### What changes were proposed in this pull request?
This PR proposes to support `ifExists` flag for v2 `ALTER TABLE ... UNSET TBLPROPERTIES` command. Currently, the flag is not respected and the command behaves as `ifExists = true` where the command always succeeds when the properties do not exist.
### Why are the changes needed?
To support `ifExists` flag and align with v1 command behavior.
### Does this PR introduce _any_ user-facing change?
Yes, now if the property does not exist and `IF EXISTS` is not specified, the command will fail:
```
ALTER TABLE t UNSET TBLPROPERTIES ('unknown') // Fails with "Attempted to unset non-existent property 'unknown'"
ALTER TABLE t UNSET TBLPROPERTIES IF EXISTS ('unknown') // OK
```
### How was this patch tested?

### What changes were proposed in this pull request?
This patch proposes to throw exception if non-streaming `Deduplicate` is not replaced by aggregate in query planner.
### Why are the changes needed?
We replace some operations in the query optimizer. For them we throw some exceptions accordingly in query planner if these logical nodes are not replaced. But `Deduplicate` is missing and it opens a possible hole. For code consistency and to prevent possible unexpected query planning error, we should add similar exception case to query planner.

### What changes were proposed in this pull request?
Creating a Pandas dataframe via Apache Arrow currently can use twice as much memory as the final result, because during the conversion, both Pandas and Arrow retain a copy of the data. Arrow has a "self-destruct" mode now (Arrow >= 0.16) to avoid this, by freeing each column after conversion. This PR integrates support for this in toPandas, handling a couple of edge cases:
self_destruct has no effect unless the memory is allocated appropriately, which is handled in the Arrow serializer here. Essentially, the issue is that self_destruct frees memory column-wise, but Arrow record batches are oriented row-wise:
```
Record batch 0: allocation 0: column 0 chunk 0, column 1 chunk 0, ...
Record batch 1: allocation 1: column 0 chunk 1, column 1 chunk 1, ...
```
In this scenario, Arrow will drop references to all of column 0's chunks, but no memory will actually be freed, as the chunks were just slices of an underlying allocation. The PR copies each column into its own allocation so that memory is instead arranged as so:
```
Record batch 0: allocation 0 column 0 chunk 0, allocation 1 column 1 chunk 0, ...
Record batch 1: allocation 2 column 0 chunk 1, allocation 3 column 1 chunk 1, ...
```
The optimization is disabled by default, and can be enabled with the Spark SQL conf "spark.sql.execution.arrow.pyspark.selfDestruct.enabled" set to "true". We can't always apply this optimization because it's more likely to generate a dataframe with immutable buffers, which Pandas doesn't always handle well, and because it is slower overall (since it only converts one column at a time instead of in parallel).
### Why are the changes needed?
This lets us load larger datasets - in particular, with N bytes of memory, before we could never load a dataset bigger than N/2 bytes; now the overhead is more like N/1.25 or so.
### Does this PR introduce _any_ user-facing change?
Yes - it adds a new SQL conf "spark.sql.execution.arrow.pyspark.selfDestruct.enabled"
### How was this patch tested?
See the [mailing list](http://apache-spark-developers-list.1001551.n3.nabble.com/DISCUSS-Reducing-memory-usage-of-toPandas-with-Arrow-quot-self-destruct-quot-option-td30149.html) - it was tested with Python memory_profiler. Unit tests added to check memory within certain bounds and correctness with the option enabled.

`TreeNodeException` causes the error msg not clear and it didn't work well.
Because the `TreeNodeException` looks redundancy, we could remove it.
There are show a case:
```
val df = Seq(("1", 1), ("1", 2), ("2", 3), ("2", 4)).toDF("x", "y")
val hashAggDF = df.groupBy("x").agg(c, sum("y"))
```
The above code will use `HashAggregateExec`. In order to ensure that an exception will be thrown when executing `HashAggregateExec`, I added `throw new RuntimeException("calculate error")` into 72b7f8abfb/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/HashAggregateExec.scala (L85)
So, if the above code is executed, `RuntimeException("calculate error")` will be thrown.
Before this PR, the error is:

### What changes were proposed in this pull request?
In the PR, I propose new option `datetimeRebaseMode` for the Avro datasource. The option influences on loading ancient dates and timestamps column values from avro files.
The option supports the same values as the SQL config `spark.sql.legacy.avro.datetimeRebaseModeInRead` namely;
- `"LEGACY"`, when an option is set to this value, Spark rebases dates/timestamps from the legacy hybrid calendar (Julian + Gregorian) to the Proleptic Gregorian calendar.
- `"CORRECTED"`, dates/timestamps are read AS IS from avro files.
- `"EXCEPTION"`, when it is set as an option value, Spark will fail the reading if it sees ancient dates/timestamps that are ambiguous between the two calendars.
### Why are the changes needed?
1. New options will allow to load avro files from at least two sources in different rebasing modes in the same query. For instance:
```scala
val df1 = spark.read.option("datetimeRebaseMode", "legacy").format("avro").load(folder1)
val df2 = spark.read.option("datetimeRebaseMode", "corrected").format("avro").load(folder2)
df1.join(df2, ...)
```
Before the changes, it is impossible because the SQL config `spark.sql.legacy.avro.datetimeRebaseModeInRead` influences on both reads.
2. Mixing of Dataset/DataFrame and RDD APIs should become possible. Since SQL configs are not propagated through RDDs, the following code fails on ancient timestamps:
```scala
spark.conf.set("spark.sql.legacy.avro.datetimeRebaseModeInRead", "legacy")
spark.read.format("avro").load(folder).distinct.rdd.collect()
```
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
By running the modified test suites:
```
$ build/sbt "test:testOnly *AvroV1Suite"
$ build/sbt "test:testOnly *AvroV2Suite"
```

### What changes were proposed in this pull request?
This PR includes the following changes:
1. in `CatalogImpl.uncacheTable`, invalidate caches in cascade when the target table is
a temp view, and `spark.sql.legacy.storeAnalyzedPlanForView` is false (default value).
2. make `SessionCatalog.lookupTempView` public and return processed temp view plan (i.e., with `View` op).
### Why are the changes needed?
Following [SPARK-34052](https://issues.apache.org/jira/browse/SPARK-34052) (#31107), we should invalidate in cascade for `CatalogImpl.uncacheTable` when the table is a temp view, so that the behavior is consistent.
### Does this PR introduce _any_ user-facing change?
Yes, now `SQLContext.uncacheTable` will drop temp view in cascade by default.

### What changes were proposed in this pull request?
This pull request exposes the `make_interval` function, [as suggested here](https://github.com/apache/spark/pull/31000#pullrequestreview-560812433), and as agreed to [here](https://github.com/apache/spark/pull/31000#issuecomment-754856820) and [here](https://github.com/apache/spark/pull/31000#issuecomment-755040234).
This powerful little function allows for idiomatic datetime arithmetic via the Scala API:
```scala
// add two hours
df.withColumn("plus_2_hours", col("first_datetime") + make_interval(hours = lit(2)))
// subtract one week and 30 seconds
col("d") - make_interval(weeks = lit(1), secs = lit(30))
```
The `make_interval` [SQL function](https://github.com/apache/spark/pull/26446) already exists.
Here is [the JIRA ticket](https://issues.apache.org/jira/browse/SPARK-33995) for this PR.
### Why are the changes needed?
The Spark API makes it easy to perform datetime addition / subtraction with months (`add_months`) and days (`date_add`). Users need to write code like this to perform datetime addition with years, weeks, hours, minutes, or seconds:
```scala
df.withColumn("plus_2_hours", expr("first_datetime + INTERVAL 2 hours"))
```
We don't want to force users to manipulate SQL strings when they're using the Scala API.
### Does this PR introduce _any_ user-facing change?
Yes, this PR adds `make_interval` to the `org.apache.spark.sql.functions` API.
This single function will benefit a lot of users. It's a small increase in the surface of the API for a big gain.
### How was this patch tested?
This was tested via unit tests.

This PR fixes the issue that `PostgresDialect` can't treat arrays of some types.
Though PostgreSQL supports wide range of types (https://www.postgresql.org/docs/13/datatype.html), the current `PostgresDialect` can't treat arrays of the following types.
* xml
* tsvector
* tsquery
* macaddr
* macaddr8
* txid_snapshot
* pg_snapshot
* point
* line
* lseg
* box
* path
* polygon
* circle
* pg_lsn
* bit varying
* interval
NOTE: PostgreSQL doesn't implement arrays of serial types so this PR doesn't care about them.

### Does this PR introduce _any_ user-facing change?
Yes. PostgresDialect can handle arrays of types shown above.

### Why are the changes needed?
This PR can help in the following scenarios:
1) Better EXPLAIN output
2) By adding `def name: String` to `UserDefinedExpression`, we can match an expression by `UserDefinedExpression` and look up the catalog, an use case needed for #31273.
### Does this PR introduce _any_ user-facing change?
The EXPLAIN output involving udfs will be changed to use the name used for UDF registration.
For example, for the following:
```
sql("CREATE TEMPORARY FUNCTION test_udf AS 'org.apache.spark.examples.sql.Spark33084'")
sql("SELECT test_udf(col1) FROM VALUES (1), (2), (3)").explain(true)
```
The output of the optimized plan will change from:
```
Aggregate [spark33084(cast(col1#223 as bigint), org.apache.spark.examples.sql.Spark330846906be0f, 1, 1) AS spark33084(col1)#237]
+- LocalRelation [col1#223]
```
to
```
Aggregate [test_udf(cast(col1#223 as bigint), org.apache.spark.examples.sql.Spark330847a62d697, 1, 1, Some(test_udf)) AS test_udf(col1)#237]
+- LocalRelation [col1#223]
```

### What changes were proposed in this pull request?
In Spark, `set -v` is defined as "Queries all properties that are defined in the SQLConf of the sparkSession".
But there are other external modules that also define properties and register them to SQLConf. In this case,
it can't be displayed by `set -v` until the conf object is initiated (i.e. calling the object at least once).
In this PR, I propose to eagerly initiate all the objects registered to SQLConf, so that `set -v` will always output
the completed properties.
### Why are the changes needed?
Improve the `set -v` command to produces completed and deterministic results
### Does this PR introduce _any_ user-facing change?
`set -v` command will dump more configs
### How was this patch tested?
existing tests
Closes#30363 from linhongliu-db/set-v.
