Signed-off-by: Dongjoon Hyun <dhyun@apple.com>
### What changes were proposed in this pull request?
This PR changes cache refreshing of v1 tables in v1 commands. In particular, v1 table dependents are not removed from the cache after this PR. Comparing to current implementation, we just clear cached data of all dependents and keep them in the cache. So, the next actions will fill in the cached data of the original v1 table and its dependents. In more details:
1. Modified the `CatalogImpl.refreshTable()` method to use `recacheByPlan()` instead of `lookupCachedData()`, `uncacheQuery()` and `cacheQuery()`. Users can call this method via public API like `spark.catalog.refreshTable()`.
2. Rewritten the part in `CatalogImpl.refreshTable()` which was responsible for table meta-data refreshing because this code stopped to work properly after removing of the second `sparkSession.table(tableIdent)`.
3. Added new private method `invalidateCachedTable()` to `SessionCatalog`. Comparing to the existing `SessionCatalog.refreshTable`, it invalidates the relation cache only. If we called `SessionCatalog.refreshTable` from `CatalogImpl.refreshTable()`, we would refresh temporary and global temporary views twice (that could lead to refreshing file index twice).
### Why are the changes needed?
1. This should improve user experience with table/view caching. For example, let's imagine that an user has cached v1 table and cached view based on the table. And the user passed the table to external library which drops/renames/adds partitions in the v1 table. Unfortunately, the user gets the view uncached after that even he/she hasn't uncached the view explicitly.
2. To improve code maintenance.
3. To reduce the amount of calls to Hive external catalog.
4. Also this should speed up table recaching.
5. To have the same behavior as for v2 tables supported by https://github.com/apache/spark/pull/31172
### Does this PR introduce _any_ user-facing change?
From the view of the correctness of query results, there are no behavior changes but the changes might influence on consuming memory and query execution time. For example:
Before:
```scala
scala> sql("CREATE TABLE tbl (c int)")
scala> sql("CACHE TABLE tbl")
scala> sql("CREATE VIEW v AS SELECT * FROM tbl")
scala> sql("CACHE TABLE v")
scala> spark.catalog.isCached("v")
res6: Boolean = true
scala> spark.catalog.refreshTable("tbl")
scala> spark.catalog.isCached("v")
res8: Boolean = false
```
After:
```scala
scala> spark.catalog.refreshTable("tbl")
scala> spark.catalog.isCached("v")
res8: Boolean = true
```
### How was this patch tested?
1. Added new unit tests that create a view, a temporary view and a global temporary view on top of v1/v2 tables, and refresh the base table via `ALTER TABLE .. ADD/DROP/RENAME PARTITION`.
2. By running the unified test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableAddPartitionSuite"
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableDropPartitionSuite"
# build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableRenamePartitionSuite"
```

This PR aims to add a note for Apache Arrow project's `PyArrow` compatibility for Python 3.9.
### Why are the changes needed?
Although Apache Spark documentation claims `Spark runs on Java 8/11, Scala 2.12, Python 3.6+ and R 3.5+.`,
Apache Arrow's `PyArrow` is not compatible with Python 3.9.x yet. Without installing `PyArrow` library, PySpark UTs passed without any problem. So, it would be enough to add a note for this limitation and the compatibility link of Apache Arrow website.

- https://github.com/apache/spark/pull/30940 (Upgrade Scala to 2.12.12, viirya )
`silencer` library is updated accordingly. And, Kafka version upgrade is required because it fails like the following.

### What changes were proposed in this pull request?
This PR aims to strip auto-generated cast. The main logic is:
1. Add tag if Cast is specified by user.
2. Wrap `PrettyAttribute` in usePrettyExpression.
### Why are the changes needed?
Make sql consistent with dsl. Here is an inconsistent example before this PR:
```
-- output field name: FLOOR(1)
spark.emptyDataFrame.select(floor(lit(1)))
-- output field name: FLOOR(CAST(1 AS DOUBLE))
spark.sql("select floor(1)")
```
Note that, we don't remove the `Cast` so the auto-generated `Cast` can still work. The only changed place is `usePrettyExpression`, we use `PrettyAttribute` replace `Cast` to give a better sql string.
### Does this PR introduce _any_ user-facing change?
Yes, the default field name may change.

### What changes were proposed in this pull request?
This is a followup PR for SPARK-33690 (#30647) .
In addition to the original PR, this PR intends to escape the following meta-characters in `Dataset#showString`.
* `\r` (carrige ret)
* `\f` (form feed)
* `\b` (backspace)
* `\u000B` (vertical tab)
* `\u0007` (bell)
### Why are the changes needed?
To avoid breaking the layout of `Dataset#showString`.
`\u0007` does not break the layout of `Dataset#showString` but it's noisy (beeps for each row) so it should be also escaped.
### Does this PR introduce _any_ user-facing change?
No.

### Why are the changes needed?
When we turn on speculation with default configs we have the last 10% of the tasks subject to speculation. There are a lot of stages where the stage runs for few seconds to minutes. Also in general we don't want to speculate tasks that run within a minimum threshold. By setting a minimum threshold for speculation config gives us better control for speculative tasks

### What changes were proposed in this pull request?
This updates SS documentation to document about State Store and task locality.
### Why are the changes needed?
During running some tests for structured streaming, I found state store locality becomes an issue sometimes and it is not very straightforward for end-users. It'd be great if we can document it.
### Does this PR introduce _any_ user-facing change?
No, only doc change.
### How was this patch tested?
No, only doc change.

### What changes were proposed in this pull request?
This is a simple change to support allocating a specified amount of overhead memory for the driver's mesos container. This is already supported for executors.
### Why are the changes needed?
This is needed to keep the driver process from exceeding memory limits and being killed off when running on mesos.
### Does this PR introduce _any_ user-facing change?
Yes, it adds a `spark.mesos.driver.memoryOverhead` configuration option. Documentation changes for this option are included in the PR.
### How was this patch tested?
Test cases covering allocation of driver memory overhead are included in the changes.
### Other notes
This is a second attempt to get this change reviewed, accepted and merged. The original pull request was closed as stale back in January: https://github.com/apache/spark/pull/21006.
For this pull request, I took the original change by pmackles, rebased it onto the current master branch, and added a test case that was requested in the original code review.
I'm happy to make any further edits or do anything needed so that this can be included in a future spark release. I keep having to build custom spark distributions so that we can use spark within our mesos clusters.

### What changes were proposed in this pull request?
This PR proposes:
- Respect `PYSPARK_PYTHON` and `PYSPARK_DRIVER_PYTHON` environment variables, or `spark.pyspark.python` and `spark.pyspark.driver.python` configurations in Kubernates just like other cluster types in Spark.
- Depreate `spark.kubernetes.pyspark.pythonVersion` and guide users to set the environment variables and configurations for Python executables.
NOTE that `spark.kubernetes.pyspark.pythonVersion` is already a no-op configuration without this PR. Default is `3` and other values are disallowed.
- In order for Python executable settings to be consistently used, fix `spark.archives` option to unpack into the current working directory in the driver of Kubernates' cluster mode. This behaviour is identical with Yarn's cluster mode. By doing this, users can leverage Conda or virtuenenv in cluster mode as below:
```python
conda create -y -n pyspark_conda_env -c conda-forge pyarrow pandas conda-pack
conda activate pyspark_conda_env
conda pack -f -o pyspark_conda_env.tar.gz
PYSPARK_PYTHON=./environment/bin/python spark-submit --archives pyspark_conda_env.tar.gz#environment app.py
```
- Removed several unused or useless codes such as `extractS3Key` and `renameResourcesToLocalFS`
### Why are the changes needed?
- To provide a consistent support of PySpark by using `PYSPARK_PYTHON` and `PYSPARK_DRIVER_PYTHON` environment variables, or `spark.pyspark.python` and `spark.pyspark.driver.python` configurations.
- To provide Conda and virtualenv support via `spark.archives` options.
### Does this PR introduce _any_ user-facing change?
Yes:
- `spark.kubernetes.pyspark.pythonVersion` is deprecated.
- `PYSPARK_PYTHON` and `PYSPARK_DRIVER_PYTHON` environment variables, and `spark.pyspark.python` and `spark.pyspark.driver.python` configurations are respected.

Currently, when casting a string as timestamp type in ANSI mode, Spark throws a runtime exception on parsing error.
However, the result for casting a string to date is always null. We should throw an exception on parsing error as well.
### Why are the changes needed?
Add missing feature for ANSI mode
### Does this PR introduce _any_ user-facing change?
Yes for ANSI mode, Casting string to date will throw an exception on parsing error
### How was this patch tested?
