### What changes were proposed in this pull request?
In the PR, I propose to change types of `DateTimeTestUtils` values and functions by replacing `java.util.TimeZone` to `java.time.ZoneId`. In particular:
1. Type of `ALL_TIMEZONES` is changed to `Seq[ZoneId]`.
2. Remove `val outstandingTimezones: Seq[TimeZone]`.
3. Change the type of the time zone parameter in `withDefaultTimeZone` to `ZoneId`.
4. Modify affected test suites.
### Why are the changes needed?
Currently, Spark SQL's date-time expressions and functions have been already ported on Java 8 time API but tests still use old time APIs. In particular, `DateTimeTestUtils` exposes functions that accept only TimeZone instances. This is inconvenient, and CPU consuming because need to convert TimeZone instances to ZoneId instances via strings (zone ids).
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
By affected test suites executed by jenkins builds.

### What changes were proposed in this pull request?
`KafkaDelegationTokenSuite` has been ignored because showed flaky behaviour. In this PR I've changed the approach how the test executed and turning it on again. This PR contains the following:
* The test runs in separate JVM in order to avoid modified security context
* The body of the test runs in `testRetry` which reties if failed
* Additional logs to analyse possible failures
* Enhanced clean-up code
### Why are the changes needed?
`KafkaDelegationTokenSuite ` is ignored.
### Does this PR introduce any user-facing change?
No.

### What changes were proposed in this pull request?
1. The tests added by #27953 are moved from `AvroLogicalTypeSuite` to `AvroSuite`.
2. Checking of the `rebaseDateTime` flag is moved out from functions bodies.
### Why are the changes needed?
1. The tests are moved because they are not directly related to logical types.
2. Checking the flag out of functions bodies should improve performance.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
By running Avro tests via the command `build/sbt avro/test`

### What changes were proposed in this pull request?
The PR addresses the issue of compatibility with Spark 2.4 and earlier version in reading/writing dates and timestamp via **Avro** datasource. Previous releases are based on a hybrid calendar - Julian + Gregorian. Since Spark 3.0, Proleptic Gregorian calendar is used by default, see SPARK-26651. In particular, the issue pops up for dates/timestamps before 1582-10-15 when the hybrid calendar switches from/to Gregorian to/from Julian calendar. The same local date in different calendar is converted to different number of days since the epoch 1970-01-01. For example, the 1001-01-01 date is converted to:
- -719164 in Julian calendar. Spark 2.4 saves the number as a value of DATE type into **Avro** files.
- -719162 in Proleptic Gregorian calendar. Spark 3.0 saves the number as a date value.
The PR proposes rebasing from/to Proleptic Gregorian calendar to the hybrid one under the SQL config:
```
spark.sql.legacy.avro.rebaseDateTime.enabled
```
which is set to `false` by default which means the rebasing is not performed by default.
The details of the implementation:
1. Re-use 2 methods of `DateTimeUtils` added by the PR https://github.com/apache/spark/pull/27915 for rebasing microseconds.
2. Re-use 2 methods of `DateTimeUtils` added by the PR https://github.com/apache/spark/pull/27915 for rebasing days.
3. Use `rebaseGregorianToJulianMicros()` and `rebaseGregorianToJulianDays()` while saving timestamps/dates to **Avro** files if the SQL config is on.
4. Use `rebaseJulianToGregorianMicros()` and `rebaseJulianToGregorianDays()` while loading timestamps/dates from **Avro** files if the SQL config is on.
5. The SQL config `spark.sql.legacy.avro.rebaseDateTime.enabled` controls conversions from/to dates, and timestamps of the `timestamp-millis`, `timestamp-micros` logical types.
### Why are the changes needed?
For the backward compatibility with Spark 2.4 and earlier versions. The changes allow users to read dates/timestamps saved by previous version, and get the same result. Also after the changes, users can enable the rebasing in write, and save dates/timestamps that can be loaded correctly by Spark 2.4 and earlier versions.
### Does this PR introduce any user-facing change?
Yes, the timestamp `1001-01-01 01:02:03.123456` saved by Spark 2.4.5 as `timestamp-micros` is interpreted by Spark 3.0.0-preview2 differently:
```scala
scala> spark.conf.set("spark.sql.session.timeZone", "America/Los_Angeles")
scala> spark.read.format("avro").load("/Users/maxim/tmp/before_1582/2_4_5_date_avro").show(false)
+----------+
|date |
+----------+
|1001-01-07|
+----------+
```
After the changes:
```scala
scala> spark.conf.set("spark.sql.legacy.avro.rebaseDateTime.enabled", true)
scala> spark.conf.set("spark.sql.session.timeZone", "America/Los_Angeles")
scala> spark.read.format("avro").load("/Users/maxim/tmp/before_1582/2_4_5_date_avro").show(false)
+----------+
|date |
+----------+
|1001-01-01|
+----------+
```
### How was this patch tested?
1. Added tests to `AvroLogicalTypeSuite` to check rebasing in read. The test reads back avro files saved by Spark 2.4.5 via:
```shell
$ export TZ="America/Los_Angeles"
```
```scala
scala> spark.conf.set("spark.sql.session.timeZone", "America/Los_Angeles")
scala> val df = Seq("1001-01-01").toDF("dateS").select($"dateS".cast("date").as("date"))
df: org.apache.spark.sql.DataFrame = [date: date]
scala> df.write.format("avro").save("/Users/maxim/tmp/before_1582/2_4_5_date_avro")
scala> val df2 = Seq("1001-01-01 01:02:03.123456").toDF("tsS").select($"tsS".cast("timestamp").as("ts"))
df2: org.apache.spark.sql.DataFrame = [ts: timestamp]
scala> df2.write.format("avro").save("/Users/maxim/tmp/before_1582/2_4_5_ts_avro")
scala> :paste
// Entering paste mode (ctrl-D to finish)
val timestampSchema = s"""
| {
| "namespace": "logical",
| "type": "record",
| "name": "test",
| "fields": [
| {"name": "ts", "type": ["null", {"type": "long","logicalType": "timestamp-millis"}], "default": null}

|""".stripMargin
// Exiting paste mode, now interpreting.
scala> df3.write.format("avro").option("avroSchema", timestampSchema).save("/Users/maxim/tmp/before_1582/2_4_5_ts_millis_avro")
```
2. Added the following tests to `AvroLogicalTypeSuite` to check rebasing of dates/timestamps (in microsecond and millisecond precision). The tests write rebased a date/timestamps and read them back w/ enabled/disabled rebasing, and compare results. :
- `rebasing microseconds timestamps in write`
- `rebasing milliseconds timestamps in write`
- `rebasing dates in write`

### What changes were proposed in this pull request?
When loading DataFrames from JDBC datasource with Kerberos authentication, remote executors (yarn-client/cluster etc. modes) fail to establish a connection due to lack of Kerberos ticket or ability to generate it.
This is a real issue when trying to ingest data from kerberized data sources (SQL Server, Oracle) in enterprise environment where exposing simple authentication access is not an option due to IT policy issues.
In this PR I've added Postgres support (other supported databases will come in later PRs).
What this PR contains:
* Added `keytab` and `principal` JDBC options
* Added `ConnectionProvider` trait and it's impementations:
* `BasicConnectionProvider` => unsecure connection
* `PostgresConnectionProvider` => postgres secure connection
* Added `ConnectionProvider` tests
* Added `PostgresKrbIntegrationSuite` docker integration test
* Created `SecurityUtils` to concentrate re-usable security related functionalities
* Documentation
### Why are the changes needed?
Missing JDBC kerberos support.
### Does this PR introduce any user-facing change?
Yes, 2 additional JDBC options added:
* keytab
* principal
If both provided then Spark does kerberos authentication.
### How was this patch tested?
To demonstrate the functionality with a standalone application I've created this repository: https://github.com/gaborgsomogyi/docker-kerberos
* Additional + existing unit tests
* Additional docker integration test
* Test on cluster manually
* `SKIP_API=1 jekyll build`

### What changes were proposed in this pull request?
We propose to add a new interface `SupportsAdmissionControl` and `ReadLimit`. A ReadLimit defines how much data should be read in the next micro-batch. `SupportsAdmissionControl` specifies that a source can rate limit its ingest into the system. The source can tell the system what the user specified as a read limit, and the system can enforce this limit within each micro-batch or impose its own limit if the Trigger is Trigger.Once() for example.
We then use this interface in FileStreamSource, KafkaSource, and KafkaMicroBatchStream.
### Why are the changes needed?
Sources currently have no information around execution semantics such as whether the stream is being executed in Trigger.Once() mode. This interface will pass this information into the sources as part of planning. With a trigger like Trigger.Once(), the semantics are to process all the data available to the datasource in a single micro-batch. However, this semantic can be broken when data source options such as `maxOffsetsPerTrigger` (in the Kafka source) rate limit the amount of data read for that micro-batch without this interface.
### Does this PR introduce any user-facing change?
DataSource developers can extend this interface for their streaming sources to add admission control into their system and correctly support Trigger.Once().
### How was this patch tested?
Existing tests, as this API is mostly internal

### What changes were proposed in this pull request?
Instead of having several overloads of `getTable` method in `TableProvider`, it's better to have 2 methods explicitly: `inferSchema` and `inferPartitioning`. With a single `getTable` method that takes everything: schema, partitioning and properties.
This PR also adds a `supportsExternalMetadata` method in `TableProvider`, to indicate if the source support external table metadata. If this flag is false:
1. spark.read.schema... is disallowed and fails
2. when we support creating v2 tables in session catalog, spark only keeps table properties in the catalog.

### What changes were proposed in this pull request?
- Add `minPartitions` support for Kafka Streaming V1 source.
- Add `minPartitions` support for Kafka batch V1 and V2 source.
- There is lots of refactoring (moving codes to KafkaOffsetReader) to reuse codes.
### Why are the changes needed?
Right now, the "minPartitions" option only works in Kafka streaming source v2. It would be great that we can support it in batch and streaming source v1 (v1 is the fallback mode when a user hits a regression in v2) as well.
### Does this PR introduce any user-facing change?
Yep. The `minPartitions` options is supported in Kafka batch and streaming queries for both data source V1 and V2.

### What changes were proposed in this pull request?
Add identifier and catalog information in DataSourceV2Relation so it would be possible to do richer checks in checkAnalysis step.

### What changes were proposed in this pull request?
Follow up on [SPARK-30428](https://github.com/apache/spark/pull/27112) which added support for partition pruning in File source V2.
This PR implements the necessary changes in order to pass the `dataFilters` to the `listFiles`. This enables having `FileIndex` implementations which use the `dataFilters` for further pruning the file listing (see the discussion [here](https://github.com/apache/spark/pull/27112#discussion_r364757217)).
### Why are the changes needed?
Datasources such as `csv` and `json` do not implement the `SupportsPushDownFilters` trait. In order to support data skipping uniformly for all file based data sources, one can override the `listFiles` method in a `FileIndex` implementation, which consults external metadata and prunes the list of files.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?

### What changes were proposed in this pull request?
In the PR, I propose to replace `.collect()`, `.count()` and `.foreach(_ => ())` in SQL benchmarks and use the `NoOp` datasource. I added an implicit class to `SqlBasedBenchmark` with the `.noop()` method. It can be used in benchmark like: `ds.noop()`. The last one is unfolded to `ds.write.format("noop").mode(Overwrite).save()`.
### Why are the changes needed?
To avoid additional overhead that `collect()` (and other actions) has. For example, `.collect()` has to convert values according to external types and pull data to the driver. This can hide actual performance regressions or improvements of benchmarked operations.

### What changes were proposed in this pull request?
This PR introduces `SupportsCatalogOptions` as an interface for `TableProvider`. Through `SupportsCatalogOptions`, V2 DataSources can implement the two methods `extractIdentifier` and `extractCatalog` to support the creation, and existence check of tables without requiring a formal TableCatalog implementation.
We currently don't support all SaveModes for DataSourceV2 in DataFrameWriter.save. The idea here is that eventually File based tables can be written with `DataFrameWriter.save(path)` will create a PathIdentifier where the name is `path`, and the V2SessionCatalog will be able to perform FileSystem checks at `path` to support ErrorIfExists and Ignore SaveModes.
### Why are the changes needed?
To support all Save modes for V2 data sources with DataFrameWriter. Since we can now support table creation, we will be able to provide partitioning information when first creating the table as well.
### Does this PR introduce any user-facing change?
Introduces a new interface
### How was this patch tested?

The Deserializer assumed that avro arrays are always of type `GenericData$Array` which is not the case.
Assuming they are from java.util.List is safer and fixes a ClassCastException in some avro code.
### What changes were proposed in this pull request?
Java.util.List has all the necessary methods and is the base class of GenericData$Array.
### Why are the changes needed?

### What changes were proposed in this pull request?
This is a follow-up of https://github.com/apache/spark/pull/26780
In https://github.com/apache/spark/pull/26780, a new Avro data source option `actualSchema` is introduced for setting the original Avro schema in function `from_avro`, while the expected schema is supposed to be set in the parameter `jsonFormatSchema` of `from_avro`.
However, there is another Avro data source option `avroSchema`. It is used for setting the expected schema in readiong and writing.
This PR is to use the option `avroSchema` option for reading Avro data with an evolved schema and remove the new one `actualSchema`
### Why are the changes needed?
Unify and simplify the Avro data source options.
### Does this PR introduce any user-facing change?
Yes.
To deserialize Avro data with an evolved schema, before changes:
```
from_avro('col, expectedSchema, ("actualSchema" -> actualSchema))
```
After changes:
```
from_avro('col, actualSchema, ("avroSchema" -> expectedSchema))
```
The second parameter is always the actual Avro schema after changes.

This patch revises Kafka producer pool (cache) to implement 'expire' correctly.
Current implementation of Kafka producer cache leverages Guava cache, which decides cached producer instance to be expired if the instance is not "accessed" from cache. The behavior defines expiration time as "last accessed time + timeout", which is incorrect because some task may use the instance longer than timeout. There's no concept of "returning" in Guava cache as well, so it cannot be fixed with Guava cache.
This patch introduces a new pool implementation which tracks "reference count" of cached instance, and defines expiration time for the instance as "last returned time + timeout" if the reference count goes 0, otherwise Long.MaxValue (effectively no expire). Expiring instances will be done with evict thread explicitly instead of evicting in part of handling acquire. (It might bring more overhead, but it ensures clearing expired instances even the pool is idle.)
This patch also creates a new package `producer` under `kafka010`, to hide the details from `kafka010` package. In point of `kafka010` package's view, only acquire()/release()/reset() are available in pool, and even for CachedKafkaProducer the package cannot close the producer directly.
Explained above.
Yes, but only for the way of expiring cached instances. (The difference is described above.) Each executor leveraging spark-sql-kafka would have one eviction thread.

### What changes were proposed in this pull request?
This patch adds close() method to the DataWriter interface, which will become the place to cleanup the resource.
### Why are the changes needed?
The lifecycle of DataWriter instance ends at either commit() or abort(). That makes datasource implementors to feel they can place resource cleanup in both sides, but abort() can be called when commit() fails; so they have to ensure they don't do double-cleanup if cleanup is not idempotent.
### Does this PR introduce any user-facing change?
Depends on the definition of user; if they're developers of custom DSv2 source, they have to add close() in their DataWriter implementations. It's OK to just add close() with empty content as they should have already dealt with resource cleanup in commit/abort, but they would love to migrate the resource cleanup logic to close() as it avoids double cleanup. If they're just end users using the provided DSv2 source (regardless of built-in/3rd party), no change.

Follow up of https://github.com/apache/spark/pull/24405
### What changes were proposed in this pull request?
The current implementation of _from_avro_ and _AvroDataToCatalyst_ doesn't allow doing schema evolution since it requires the deserialization of an Avro record with the exact same schema with which it was serialized.
The proposed change is to add a new option `actualSchema` to allow passing the schema used to serialize the records. This allows using a different compatible schema for reading by passing both schemas to _GenericDatumReader_. If no writer's schema is provided, nothing changes from before.
### Why are the changes needed?
Consider the following example.
```
// schema ID: 1
val schema1 = """
{
"type": "record",
"name": "MySchema",
"fields": [
{"name": "col1", "type": "int"},
{"name": "col2", "type": "string"}
]
}
"""
// schema ID: 2
val schema2 = """
{
"type": "record",
"name": "MySchema",
"fields": [
{"name": "col1", "type": "int"},
{"name": "col2", "type": "string"},
{"name": "col3", "type": "string", "default": ""}
]
}
"""
```
The two schemas are compatible - i.e. you can use `schema2` to deserialize events serialized with `schema1`, in which case there will be the field `col3` with the default value.
Now imagine that you have two dataframes (read from batch or streaming), one with Avro events from schema1 and the other with events from schema2. **We want to combine them into one dataframe** for storing or further processing.
With the current `from_avro` function we can only decode each of them with the corresponding schema:
```
scalaval df1 = ... // Avro events created with schema1
df1: org.apache.spark.sql.DataFrame = [eventBytes: binary]
scalaval decodedDf1 = df1.select(from_avro('eventBytes, schema1) as "decoded")
decodedDf1: org.apache.spark.sql.DataFrame = [decoded: struct<col1: int, col2: string>]
scalaval df2= ... // Avro events created with schema2
df2: org.apache.spark.sql.DataFrame = [eventBytes: binary]
scalaval decodedDf2 = df2.select(from_avro('eventBytes, schema2) as "decoded")
decodedDf2: org.apache.spark.sql.DataFrame = [decoded: struct<col1: int, col2: string, col3: string>]
```
but then `decodedDf1` and `decodedDf2` have different Spark schemas and we can't union them. Instead, with the proposed change we can decode `df1` in the following way:
```
scalaimport scala.collection.JavaConverters._
scalaval decodedDf1 = df1.select(from_avro(data = 'eventBytes, jsonFormatSchema = schema2, options = Map("actualSchema" -> schema1).asJava) as "decoded")
decodedDf1: org.apache.spark.sql.DataFrame = [decoded: struct<col1: int, col2: string, col3: string>]
```
so that both dataframes have the same schemas and can be merged.

### What changes were proposed in this pull request?
Before this PR, the method `checkAnswer` in Object `QueryTest` returns an optional string. It doesn't throw exceptions when errors happen.
The actual exceptions are thrown in the trait `QueryTest`.
However, there are some test suites(`StreamSuite`, `SessionStateSuite`, `BinaryFileFormatSuite`, etc.) that use the no-op method `QueryTest.checkAnswer` and expect it to fail test cases when the execution results don't match the expected answers.
After this PR:
1. the method `checkAnswer` in Object `QueryTest` will fail tests on errors or unexpected results.
2. add a new method `getErrorMessageInCheckAnswer`, which is exactly the same as the previous version of `checkAnswer`. There are some test suites use this one to customize the test failure message.
3. for the test suites that extend the trait `QueryTest`, we should use the method `checkAnswer` directly, instead of calling the method from Object `QueryTest`.
### Why are the changes needed?
We should fix these method calls to perform actual validations in test suites.

Hadoop jira: https://issues.apache.org/jira/browse/HADOOP-12911
In this jira, the author said to replace origin Apache Directory project which is not maintained (but not said it won't work well in jdk11) to Apache Kerby which is java binding(fit java version).
And in Flink: https://github.com/apache/flink/pull/9622
Author show the reason why hadoop-2.7.2's `MminiKdc` failed with jdk11.
Because new encryption types of `es128-cts-hmac-sha256-128` and `aes256-cts-hmac-sha384-192` (for Kerberos 5) enabled by default were added in Java 11.
Spark with `hadoop-2.7's MiniKdc`does not support these encryption types and does not work well when these encryption types are enabled, which results in the authentication failure.
And when I test hadoop-2.7.2's minikdc in local, the kerberos 's debug error message is read message stream failed, message can't match.

### What changes were proposed in this pull request?
When implementing a ScanBuilder, we require the implementor to provide the schema of the data and the number of partitions.
However, when someone is implementing WriteBuilder we only pass them the schema, but not the number of partitions. This is an asymetrical developer experience.
This PR adds a PhysicalWriteInfo interface that is passed to createBatchWriterFactory and createStreamingWriterFactory that adds the number of partitions of the data that is going to be written.
### Why are the changes needed?
Passing in the number of partitions on the WriteBuilder would enable data sources to provision their write targets before starting to write. For example:
it could be used to provision a Kafka topic with a specific number of partitions
it could be used to scale a microservice prior to sending the data to it
it could be used to create a DsV2 that sends the data to another spark cluster (currently not possible since the reader wouldn't be able to know the number of partitions)

Fixed Unit test cases to where applicable and added new E2E test cases in to test table read/write using ShortType and ByteType.
#### Problems
- In master in JDBCUtils.scala line number 547 and 551 have a problem where ShortType and ByteType are set as Integers rather than set as Short and Byte respectively.
```
case ShortType =>
(stmt: PreparedStatement, row: Row, pos: Int) =>
stmt.setInt(pos + 1, row.getShort(pos))
The issue was pointed out by maropu
case ByteType =>
(stmt: PreparedStatement, row: Row, pos: Int) =>
stmt.setInt(pos + 1, row.getByte(pos))
```
- Also at line JDBCUtils.scala 247 TinyInt is interpreted wrongly as IntergetType in getCatalystType()
``` case java.sql.Types.TINYINT => IntegerType ```
- At line 172 ShortType was wrongly interpreted as IntegerType
``` case ShortType => Option(JdbcType("INTEGER", java.sql.Types.SMALLINT)) ```
- All thru out tests, ShortType and ByteType were being interpreted as IntegerTypes.
### Why are the changes needed?

### What changes were proposed in this pull request?
Kafka producers are now closed when `spark.kafka.producer.cache.timeout` reached which could be significant problem when processing big SQL queries. The workaround was to increase `spark.kafka.producer.cache.timeout` to a number where the biggest SQL query can be finished.
In this PR I've adapted similar solution which already exists on the consumer side, namely applies Apache Commons Pool on the producer side as well. Main advantages choosing this solution:
* Producers are not closed until they're in use
* No manual reference counting needed (which may be error prone)
* Thread-safe by design
* Provides jmx connection to the pool where metrics can be fetched
What this PR contains:
* Introduced producer side parameters to configure pool
* Renamed `InternalKafkaConsumerPool` to `InternalKafkaConnectorPool` and made it abstract
* Created 2 implementations from it: `InternalKafkaConsumerPool` and `InternalKafkaProducerPool`
* Adapted `CachedKafkaProducer` to use `InternalKafkaProducerPool`
* Changed `KafkaDataWriter` and `KafkaDataWriteTask` to release producer even in failure scenario
* Added several new tests
* Extended `KafkaTest` to clear not only producers but consumers as well
* Renamed `InternalKafkaConsumerPoolSuite` to `InternalKafkaConnectorPoolSuite` where only consumer tests are checking the behavior (please see comment for reasoning)
What this PR not yet contains(but intended when the main concept is stable):
* User facing documentation
### Why are the changes needed?
Kafka producer closed after 10 minutes (with default settings).
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
