### What changes were proposed in this pull request?
- Building spark internally in orgs where access to outside internet is not allowed takes a long time because unsuccessful attempts are made to download artifacts from repositories which are not accessible. The unsuccessful attempts unnecessarily add significant amount of time to the build. I have seen a difference of up-to 1hr for some runs.
- Adding 1 environment variables that should be present that the start of the build and if they exist, override the default repos defined in the code and scripts.
envVariables:
- DEFAULT_ARTIFACT_REPOSITORY=https://artifacts.internal.com/libs-release/
### Why are the changes needed?
To allow orgs to build spark internally without relying on external repositories for artifact downloads.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
1. Replace the metadata key `org.apache.spark.int96NoRebase` by `org.apache.spark.legacyINT96`.
2. Change the condition when new key should be saved to parquet metadata: it should be saved when the SQL config `spark.sql.legacy.parquet.int96RebaseModeInWrite` is set to `LEGACY`.
3. Change handling the metadata key in read:
- If there is no the key in parquet metadata, take the rebase mode from the SQL config: `spark.sql.legacy.parquet.int96RebaseModeInRead`
- If parquet files were saved by Spark < 3.1.0, use the `LEGACY` rebasing mode for INT96 type.
- For files written by Spark >= 3.1.0, if the `org.apache.spark.legacyINT96` presents in metadata, perform rebasing otherwise don't.
### Why are the changes needed?
- To not increase parquet size by default when `spark.sql.legacy.parquet.int96RebaseModeInWrite` is `EXCEPTION` after https://github.com/apache/spark/pull/30121.
- To have the implementation similar to `org.apache.spark.legacyDateTime`
- To minimise impact on other subsystems that are based on file sizes like gathering statistics.

The purpose of this pr is to resolve SPARK-32978.
The main reason of bad case describe in SPARK-32978 is the `BasicWriteTaskStatsTracker` directly reports the new added partition number of each task, which makes it impossible to remove duplicate data in driver side.
The main of this pr is change to report partitionValues to driver and remove duplicate data at driver side to make sure the number of dynamic part metric is correct.
### Why are the changes needed?

Support `spark.sql.hive.metastore.jars` use HDFS location.
When user need to use path to set hive metastore jars, you should set
`spark.sql.hive.metasstore.jars=path` and set real path in `spark.sql.hive.metastore.jars.path`
since we use `File.pathSeperator` to split path, but `FIle.pathSeparator` is `:` in unix, it will split hdfs location `hdfs://nameservice/xx`. So add new config `spark.sql.hive.metastore.jars.path` to set comma separated paths.
To keep both two way supported
### Why are the changes needed?

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

### What changes were proposed in this pull request?
This updates the misleading log messages for removed shuffle block during migration.
### Why are the changes needed?
1. For the deleted shuffle blocks, `IndexShuffleBlockResolver` shows users WARN message saying `skipping migration`. However, `BlockManagerDecommissioner` shows users INFO message including `Migrated ShuffleBlockInfo(...)` inconsistently. Technically, we didn't migrated. We should not show `Migrated` message in this case.
```
INFO BlockManagerDecommissioner: Trying to migrate shuffle ShuffleBlockInfo(109,18924) to BlockManagerId(...) (2 / 3)
WARN IndexShuffleBlockResolver: Failed to resolve shuffle block ShuffleBlockInfo(109,18924), skipping migration. This is expected to occur if a block is removed after decommissioning has started.
INFO BlockManagerDecommissioner: Got migration sub-blocks List()
...
INFO BlockManagerDecommissioner: Migrated ShuffleBlockInfo(109,18924) to BlockManagerId(...)
```
2. In addition, if the shuffle file is deleted while the information is in the queue, the above messages are repeated multiple times, `spark.storage.decommission.maxReplicationFailuresPerBlock`. We had better use one line instead of the group of messages for that case.
```
INFO BlockManagerDecommissioner: Trying to migrate shuffle ShuffleBlockInfo(109,18924) to BlockManagerId(...) (0 / 3)
...
INFO BlockManagerDecommissioner: Trying to migrate shuffle ShuffleBlockInfo(109,18924) to BlockManagerId(...) (1 / 3)
...
INFO BlockManagerDecommissioner: Trying to migrate shuffle ShuffleBlockInfo(109,18924) to BlockManagerId(...) (2 / 3)
```
3. Skipping or not is a role of `BlockManagerDecommissioner` class. `IndexShuffleBlockResolver.getMigrationBlocks` is used twice differently like the following. We had better inform users at `BlockManagerDecommissioner` once.
- At the beginning, to get the sub-blocks.
- In case of `IOException`, to determine whether ignoring it or re-throwing. And, `BlockManagerDecommissioner` shows WARN message (`Skipping block ...`) again.
### Does this PR introduce _any_ user-facing change?
No. This is an update for log message info to be consistent.
### How was this patch tested?

### What changes were proposed in this pull request?
`REGEXP_REPLACE` could replace all substrings of string that match regexp with replacement string.
But `REGEXP_REPLACE` lost some flexibility. such as: converts camel case strings to a string containing lower case words separated by an underscore:
AddressLine1 -> address_line_1
If we support the parameter position, we can do like this(e.g. Oracle):
```
WITH strings as (
SELECT 'AddressLine1' s FROM dual union all
SELECT 'ZipCode' s FROM dual union all
SELECT 'Country' s FROM dual
)
SELECT s "STRING",
lower(regexp_replace(s, '([A-Z0-9])', '_\1', 2)) "MODIFIED_STRING"
FROM strings;
```
The output:
```
STRING MODIFIED_STRING
-------------------- --------------------
AddressLine1 address_line_1
ZipCode zip_code
Country country
```
There are some mainstream database support the syntax.

### What changes were proposed in this pull request?
This switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x. For Hadoop 2.7, we'll still use the same modules such as hadoop-client.
In order to still keep default Hadoop profile to be hadoop-3.2, this defines the following Maven properties:
```
hadoop-client-api.artifact
hadoop-client-runtime.artifact
hadoop-client-minicluster.artifact
```
which default to:
```
hadoop-client-api
hadoop-client-runtime
hadoop-client-minicluster
```
but all switch to `hadoop-client` when the Hadoop profile is hadoop-2.7. A side affect from this is we'll import the same dependency multiple times. For this I have to disable Maven enforcer `banDuplicatePomDependencyVersions`.
Besides above, there are the following changes:
- explicitly add a few dependencies which are imported via transitive dependencies from Hadoop jars, but are removed from the shaded client jars.
- removed the use of `ProxyUriUtils.getPath` from `ApplicationMaster` which is a server-side/private API.
- modified `IsolatedClientLoader` to exclude `hadoop-auth` jars when Hadoop version is 3.x. This change should only matter when we're not sharing Hadoop classes with Spark (which is _mostly_ used in tests).
### Why are the changes needed?
This serves two purposes:
- to unblock Spark from upgrading to Hadoop 3.2.2/3.3.0+. Latest Hadoop versions have upgraded to use Guava 27+ and in order to adopt the latest Hadoop versions in Spark, we'll need to resolve the Guava conflicts. This takes the approach by switching to shaded client jars provided by Hadoop.
- avoid pulling 3rd party dependencies from Hadoop and avoid potential future conflicts.
### Does this PR introduce _any_ user-facing change?
When people use Spark with `hadoop-provided` option, they should make sure class path contains `hadoop-client-api` and `hadoop-client-runtime` jars. In addition, they may need to make sure these jars appear before other Hadoop jars in the order. Otherwise, classes may be loaded from the other non-shaded Hadoop jars and cause potential conflicts.

### What changes were proposed in this pull request?
This PR is a small followup of https://github.com/apache/spark/pull/28793 and proposes to use `is_categorical_dtype` instead of deprecated `is_categorical`.
`is_categorical_dtype` exists from minimum pandas version we support (https://github.com/pandas-dev/pandas/blob/v0.23.2/pandas/core/dtypes/api.py), and `is_categorical` was deprecated from pandas 1.1.0 (87a1cc21ca).
### Why are the changes needed?
To avoid using deprecated APIs, and remove warnings.
### Does this PR introduce _any_ user-facing change?
Yes, it will remove warnings that says `is_categorical` is deprecated.
### How was this patch tested?
By running any pandas UDF with pandas 1.1.0+:
```python
import pandas as pd
from pyspark.sql.functions import pandas_udf
def func(x: pd.Series) -> pd.Series:
return x
spark.range(10).select(pandas_udf(func, "long")("id")).show()
```
Before:
```
/.../python/lib/pyspark.zip/pyspark/sql/pandas/serializers.py:151: FutureWarning: is_categorical is deprecated and will be removed in a future version. Use is_categorical_dtype instead
...
```

### What changes were proposed in this pull request?
This PR changes `<` into `>` in the following to fix data loss during storage migrations.
```scala
// If we found any new shuffles to migrate or otherwise have not migrated everything.
- newShufflesToMigrate.nonEmpty || migratingShuffles.size < numMigratedShuffles.get()
+ newShufflesToMigrate.nonEmpty || migratingShuffles.size > numMigratedShuffles.get()
```
### Why are the changes needed?
`refreshOffloadingShuffleBlocks` should return `true` when the migration is still on-going.
Since `migratingShuffles` is defined like the following, `migratingShuffles.size > numMigratedShuffles.get()` means the migration is not finished.
```scala
// Shuffles which are either in queue for migrations or migrated
protected[storage] val migratingShuffles = mutable.HashSet[ShuffleBlockInfo]()

I think this was broken when Python 2 was dropped but was not caught because this specific test does not run when there's no change in YARN codes. See also https://github.com/apache/spark/pull/29843#issuecomment-712540024
The root cause seems like the paths are different, see https://github.com/apache/spark/pull/29843#pullrequestreview-502595199. I _think_ Jenkins uses a different Python executable via Anaconda and the executor side does not know where it is for some reasons.
This PR proposes to fix it just by explicitly specifying the absolute path for Python executable so the tests should pass in any environment.

### Why are the changes needed?
To make build pass.
### Does this PR introduce _any_ user-facing change?
No, dev-only.
### How was this patch tested?
GitHub Actions in this build will test it out.

### What changes were proposed in this pull request?
Postgres and MSSQL connection providers are not able to get custom `appEntry` because under some circumstances the driver is wrapped with `DriverWrapper`. Such case is not handled in the mentioned providers. In this PR I've added this edge case handling by passing unwrapped `Driver` from `JdbcUtils`.
### Why are the changes needed?
`DriverWrapper` is not considered.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Existing + additional unit tests.

### What changes were proposed in this pull request?
1. Add the SQL config `spark.sql.legacy.parquet.int96RebaseModeInWrite` to control timestamps rebasing in saving them as INT96. It supports the same set of values as `spark.sql.legacy.parquet.datetimeRebaseModeInWrite` but the default value is `LEGACY` to preserve backward compatibility with Spark <= 3.0.
2. Write the metadata key `org.apache.spark.int96NoRebase` to parquet files if the files are saved with `spark.sql.legacy.parquet.int96RebaseModeInWrite` isn't set to `LEGACY`.
3. Add the SQL config `spark.sql.legacy.parquet.datetimeRebaseModeInRead` to control loading INT96 timestamps when parquet metadata doesn't have enough info (the `org.apache.spark.int96NoRebase` tag) about parquet writer - either INT96 was written by Proleptic Gregorian system or some Julian one.
4. Modified Vectorized and Parquet-mr Readers to support loading/saving INT96 timestamps w/o rebasing depending on SQL config and the metadata tag:
- **No rebasing** in testing when the SQL config `spark.test.forceNoRebase` is set to `true`
- **No rebasing** if parquet metadata contains the tag `org.apache.spark.int96NoRebase`. This is the case when parquet files are saved by Spark >= 3.1 with `spark.sql.legacy.parquet.datetimeRebaseModeInWrite` is set to `CORRECTED`, or saved by other systems with the tag `org.apache.spark.int96NoRebase`.
- **With rebasing** if parquet files saved by Spark (any versions) without the metadata tag `org.apache.spark.int96NoRebase`.
- Rebasing depend on the SQL config `spark.sql.legacy.parquet.datetimeRebaseModeInRead` if there are no metadata tags `org.apache.spark.version` and `org.apache.spark.int96NoRebase`.
New SQL configs are added instead of re-using existing `spark.sql.legacy.parquet.datetimeRebaseModeInWrite` and `spark.sql.legacy.parquet.datetimeRebaseModeInRead` because of:
- To allow users have different modes for INT96 and for TIMESTAMP_MICROS (MILLIS). For example, users might want to save INT96 as LEGACY but TIMESTAMP_MICROS as CORRECTED.
- To have different modes for INT96 and DATE in load (or in save).
- To be backward compatible with Spark 2.4. For now, `spark.sql.legacy.parquet.datetimeRebaseModeInWrite/Read` are set to `EXCEPTION` by default.
### Why are the changes needed?
1. Parquet spec says that INT96 must be stored as Julian days (see https://github.com/apache/parquet-format/pull/49). This doesn't mean that a reader ( or a writer) is based on the Julian calendar. So, rebasing from Proleptic Gregorian to Julian calendar can be not needed.
2. Rebasing from/to Julian calendar can loose information because dates in one calendar don't exist in another one. Like 1582-10-04..1582-10-15 exist in Proleptic Gregorian calendar but not in the hybrid calendar (Julian + Gregorian), and visa versa, Julian date 1000-02-29 doesn't exist in Proleptic Gregorian calendar. We should allow users to save timestamps without loosing such dates (rebasing shifts such dates to the next valid date).
3. It would also make Spark compatible with other systems such as Impala and newer versions of Hive that write proleptic Gregorian based INT96 timestamps.
### Does this PR introduce _any_ user-facing change?
It can when `spark.sql.legacy.parquet.int96RebaseModeInWrite` is set non-default value `LEGACY`.
### How was this patch tested?
- Added a test to check the metadata key `org.apache.spark.int96NoRebase`
- By `ParquetIOSuite`

### What changes were proposed in this pull request?
Currently, actual non-dynamic partition pruning is executed in the optimizer phase (PruneFileSourcePartitions) if an input relation has a catalog file index. The current code assumes the same partition filters are generated again in FileSourceStrategy and passed into FileSourceScanExec. FileSourceScanExec uses the partition filters when listing files, but these non-dynamic partition filters do nothing because unnecessary partitions are already pruned in advance, so the filters are mainly used for explain output in this case. If a WHERE clause has DNF-ed predicates, FileSourceStrategy cannot extract the same filters with PruneFileSourcePartitions and then PartitionFilters is not shown in explain output.
This patch proposes to extract partition filters in FileSourceStrategy and HiveStrategy with `extractPredicatesWithinOutputSet` added in https://github.com/apache/spark/pull/29101/files#diff-6be42cfa3c62a7536b1eb1d6447c073c again, then It will show the partially pushed down partition filter in explain().
### Why are the changes needed?
without the patch, the explained plan is inconsistent with what is actually executed
<b>without the change </b> the explained plan of `"SELECT * FROM t WHERE p = '1' OR (p = '2' AND i = 1)"` for datasource and hive tables are like the following respectively (missing pushed down partition filters)
```

### What changes were proposed in this pull request?
This patch proposes to add more optimization to `UpdateFields` expression chain. And optimize `UpdateFields` early in analysis phase.
### Why are the changes needed?
`UpdateFields` can manipulate complex nested data, but using `UpdateFields` can easily create inefficient expression chain. We should optimize it further.
Because when manipulating deeply nested schema, the `UpdateFields` expression tree could be too complex to analyze, this change optimizes `UpdateFields` early in analysis phase.

### What changes were proposed in this pull request?
This patch proposes to add a config we can control fast-fail behavior in FileFormatWriter and set it false by default.
### Why are the changes needed?
In SPARK-29649, we catch `FileAlreadyExistsException` in `FileFormatWriter` and fail fast for the task set to prevent task retry.
Due to latest discussion, it is important to be able to keep original behavior that is to retry tasks even `FileAlreadyExistsException` is thrown, because `FileAlreadyExistsException` could be recoverable in some cases.
We are going to add a config we can control this behavior and set it false for fast-fail by default.
### Does this PR introduce _any_ user-facing change?
Yes. By default the task in FileFormatWriter will retry even if `FileAlreadyExistsException` is thrown. This is the behavior before Spark 3.0. User can control fast-fail behavior by enabling it.

The behavior after this PR:
```scala
scala> df1.unionByName(df2, true).printSchema
root
|-- c0: long (nullable = false)
|-- c1: struct (nullable = false)
| |-- a: long (nullable = true)
| |-- b: long (nullable = false)
| |-- c: long (nullable = false)
scala> df1.unionByName(df2, true).show()

| 0| {3, 2, 1}|
| 0|{ null, 2, 1}|

### Why are the changes needed?
The `allowMissingColumns` of `unionByName` is a feature allowing merging different schema from two datasets when unioning them together. Nested column support makes the feature more general and flexible for usage.
### Does this PR introduce _any_ user-facing change?
Yes, after this change users can union two datasets with different schema with different structs.
### How was this patch tested?
Unit tests.
Closes#29587 from viirya/SPARK-32376.

### What changes were proposed in this pull request?
If a block is removed between discovery to transfer fo the block, we short circuit that block and remove it from the list to transfer and increment the transferred blocks. This is complicated since both RPC errors and local read errors may be reported with the same exception class.
### Why are the changes needed?
Slow shuffle refreshes could waste time when decommissioning has already finished. Decommissioning might avoid transferring some some blocks to an otherwise live host which is marked as "full" if a deleted block fails to transfer to that host.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
New unit and integration tests.

### What changes were proposed in this pull request?
The function `binaryToSQLTimestamp()` is used by Parquet Vectorized reader. Parquet MR reader has similar code for de-serialization of INT96 timestamps. In this PR, I propose to de-duplicate code and re-use `binaryToSQLTimestamp()`.
### Why are the changes needed?
This should improve maintenance, and should allow to avoid errors while changing Vectorized and regular parquet readers.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
By existing test suites, for instance `ParquetIOSuite`.

### What changes were proposed in this pull request?
This PR aims to mark ParquetV1FilterSuite and ParquetV2FilterSuite as `ExtendedSQLTest`.
- ParquetV1FilterSuite/ParquetV2FilterSuite
- ParquetV1SchemaPruningSuite/ParquetV2SchemaPruningSuite
### Why are the changes needed?
Currently, `sql - other tests` is the longest job. This PR will move the above tests to `sql - slow tests` job.
