After the newly added shuffle block fetching protocol in #24565, we can keep this work by extending the FetchShuffleBlocks message.
### What changes were proposed in this pull request?
In this patch, we achieve the indeterminate shuffle rerun by reusing the task attempt id(unique id within an application) in shuffle id, so that each shuffle write attempt has a different file name. For the indeterministic stage, when the stage resubmits, we'll clear all existing map status and rerun all partitions.
All changes are summarized as follows:
- Change the mapId to mapTaskAttemptId in shuffle related id.
- Record the mapTaskAttemptId in MapStatus.
- Still keep mapId in ShuffleFetcherIterator for fetch failed scenario.
- Add the determinate flag in Stage and use it in DAGScheduler and the cleaning work for the intermediate stage.
### Why are the changes needed?
This is a follow-up work for #22112's future improvment[1]: `Currently we can't rollback and rerun a shuffle map stage, and just fail.`
Spark will rerun a finished shuffle write stage while meeting fetch failures, currently, the rerun shuffle map stage will only resubmit the task for missing partitions and reuse the output of other partitions. This logic is fine in most scenarios, but for indeterministic operations(like repartition), multiple shuffle write attempts may write different data, only rerun the missing partition will lead a correctness bug. So for the shuffle map stage of indeterministic operations, we need to support rolling back the shuffle map stage and re-generate the shuffle files.
### Does this PR introduce any user-facing change?
Yes, after this PR, the indeterminate stage rerun will be accepted by rerunning the whole stage. The original behavior is aborting the stage and fail the job.
### How was this patch tested?
- UT: Add UT for all changing code and newly added function.
- Manual Test: Also providing a manual test to verify the effect.
```
import scala.sys.process._
import org.apache.spark.TaskContext
val determinateStage0 = sc.parallelize(0 until 1000 * 1000 * 100, 10)
val indeterminateStage1 = determinateStage0.repartition(200)
val indeterminateStage2 = indeterminateStage1.repartition(200)
val indeterminateStage3 = indeterminateStage2.repartition(100)
val indeterminateStage4 = indeterminateStage3.repartition(300)
val fetchFailIndeterminateStage4 = indeterminateStage4.map { x =>
if (TaskContext.get.attemptNumber == 0 && TaskContext.get.partitionId == 190 &&
TaskContext.get.stageAttemptNumber == 0) {
throw new Exception("pkill -f -n java".!!)
}
x
}
val indeterminateStage5 = fetchFailIndeterminateStage4.repartition(200)
val finalStage6 = indeterminateStage5.repartition(100).collect().distinct.length
```
It's a simple job with multi indeterminate stage, it will get a wrong answer while using old Spark version like 2.2/2.3, and will be killed after #22112. With this fix, the job can retry all indeterminate stage as below screenshot and get the right result.

### What changes were proposed in this pull request?
Supported special string values for `DATE` type. They are simply notational shorthands that will be converted to ordinary date values when read. The following string values are supported:
- `epoch [zoneId]` - `1970-01-01`
- `today [zoneId]` - the current date in the time zone specified by `spark.sql.session.timeZone`.
- `yesterday [zoneId]` - the current date -1
- `tomorrow [zoneId]` - the current date + 1
- `now` - the date of running the current query. It has the same notion as `today`.
For example:
```sql
spark-sql> SELECT date 'tomorrow' - date 'yesterday';
2
```
### Why are the changes needed?
To maintain feature parity with PostgreSQL, see [8.5.1.4. Special Values](https://www.postgresql.org/docs/12/datatype-datetime.html)
### Does this PR introduce any user-facing change?
Previously, the parser fails on the special values with the error:
```sql
spark-sql> select date 'today';
Error in query:
Cannot parse the DATE value: today(line 1, pos 7)
```
After the changes, the special values are converted to appropriate dates:
```sql
spark-sql> select date 'today';
2019-09-06
```
### How was this patch tested?
- Added tests to `DateFormatterSuite` to check parsing special values from regular strings.
- Tests in `DateTimeUtilsSuite` check parsing those values from `UTF8String`
- Uncommented tests in `date.sql`

Credit to vanzin as he found and commented on this while reviewing #25670 - [comment](https://github.com/apache/spark/pull/25670#discussion_r325383512).
This patch proposes to specify UTF-8 explicitly while reading/writer event log file.
### Why are the changes needed?
The event log file is being read/written as default character set of JVM process which may open the chance to bring some problems on reading event log files from another machines. Spark's de facto standard character set is UTF-8, so it should be explicitly set to.
### Does this PR introduce any user-facing change?
Yes, if end users have been running Spark process with different default charset than "UTF-8", especially their driver JVM processes. No otherwise.
### How was this patch tested?
Existing UTs, as ReplayListenerSuite contains "end-to-end" event logging/reading tests (both uncompressed/compressed).

### What changes were proposed in this pull request?
This patch fixes the issue brought by [SPARK-21870](http://issues.apache.org/jira/browse/SPARK-21870): when generating code for parameter type, it doesn't consider array type in javaType. At least we have one, Spark should generate code for BinaryType as `byte[]`, but Spark create the code for BinaryType as `[B` and generated code fails compilation.
Below is the generated code which failed compilation (Line 380):
```
/* 380 */ private void agg_doAggregate_count_0([B agg_expr_1_1, boolean agg_exprIsNull_1_1, org.apache.spark.sql.catalyst.InternalRow agg_unsafeRowAggBuffer_1) throws java.io.IOException {
/* 381 */ // evaluate aggregate function for count
/* 382 */ boolean agg_isNull_26 = false;
/* 383 */ long agg_value_28 = -1L;
/* 384 */ if (!false && agg_exprIsNull_1_1) {
/* 385 */ long agg_value_31 = agg_unsafeRowAggBuffer_1.getLong(1);
/* 386 */ agg_isNull_26 = false;
/* 387 */ agg_value_28 = agg_value_31;
/* 388 */ } else {
/* 389 */ long agg_value_33 = agg_unsafeRowAggBuffer_1.getLong(1);
/* 390 */
/* 391 */ long agg_value_32 = -1L;
/* 392 */
/* 393 */ agg_value_32 = agg_value_33 + 1L;
/* 394 */ agg_isNull_26 = false;
/* 395 */ agg_value_28 = agg_value_32;
/* 396 */ }
/* 397 */ // update unsafe row buffer
/* 398 */ agg_unsafeRowAggBuffer_1.setLong(1, agg_value_28);
/* 399 */ }
```
There wasn't any test for HashAggregateExec specifically testing this, but randomized test in ObjectHashAggregateSuite could encounter this and that's why ObjectHashAggregateSuite is flaky.

### What changes were proposed in this pull request?
In the PR, I propose to change behavior of the `date_part()` function in handling `null` field, and make it the same as PostgreSQL has. If `field` parameter is `null`, the function should return `null` of the `double` type as PostgreSQL does:
```sql
# select date_part(null, date '2019-09-20');
date_part
-----------
(1 row)
# select pg_typeof(date_part(null, date '2019-09-20'));
pg_typeof
------------------
double precision
(1 row)
```
### Why are the changes needed?
The `date_part()` function was added to maintain feature parity with PostgreSQL but current behavior of the function is different in handling null as `field`.
### Does this PR introduce any user-facing change?
Yes.
Before:
```sql

After:
```sql
spark-sql> select date_part(null, date'2019-09-20');

```

### Why are the changes needed?
Before this change, when you have a joined table that has the same field name from both original table, fillna will fail even if you specify a subset that does not include the 'ambiguous' fields.
```
scala> val df1 = Seq(("f1-1", "f2", null), ("f1-2", null, null), ("f1-3", "f2", "f3-1"), ("f1-4", "f2", "f3-1")).toDF("f1", "f2", "f3")
scala> val df2 = Seq(("f1-1", null, null), ("f1-2", "f2", null), ("f1-3", "f2", "f4-1")).toDF("f1", "f2", "f4")
scala> val df_join = df1.alias("df1").join(df2.alias("df2"), Seq("f1"), joinType="left_outer")
scala> df_join.na.fill("", cols=Seq("f4"))
org.apache.spark.sql.AnalysisException: Reference 'f2' is ambiguous, could be: df1.f2, df2.f2.;

Switch from using a Thread sleep for waiting for commands to finish to just waiting for the command to finish with a watcher & improve the error messages in the SecretsTestsSuite.
### Why are the changes needed?
Currently some of the Spark Kubernetes tests have race conditions with command execution, and the frequent use of eventually makes debugging test failures difficult.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Existing tests pass after removal of thread.sleep

### What changes were proposed in this pull request?
This PR allows Python toLocalIterator to prefetch the next partition while the first partition is being collected. The PR also adds a demo micro bench mark in the examples directory, we may wish to keep this or not.
### Why are the changes needed?
In https://issues.apache.org/jira/browse/SPARK-23961 / 5e79ae3b40 we changed PySpark to only pull one partition at a time. This is memory efficient, but if partitions take time to compute this can mean we're spending more time blocking.
### Does this PR introduce any user-facing change?
A new param is added to toLocalIterator
### How was this patch tested?
New unit test inside of `test_rdd.py` checks the time that the elements are evaluated at. Another test that the results remain the same are added to `test_dataframe.py`.
I also ran a micro benchmark in the examples directory `prefetch.py` which shows an improvement of ~40% in this specific use case.

### What changes were proposed in this pull request?
This patch proposes to increase timeout to wait for executor(s) to be up in SparkContextSuite, as we observed these tests failed due to wait timeout.
### Why are the changes needed?
There's some case that CI build is extremely slow which requires 3x or more time to pass the test.

Allocating higher timeout wouldn't bring additional latency, as the code checks the condition with sleeping 10 ms per loop iteration.

### What changes were proposed in this pull request?
Currently the checks in the Analyzer require that V2 Tables have BATCH_WRITE defined for all tables that have V1 Write fallbacks. This is confusing as these tables may not have the V2 writer interface implemented yet. This PR adds this table capability to these checks.
In addition, this allows V2 tables to leverage the V1 APIs for DataFrameWriter.save if they do extend the V1_BATCH_WRITE capability. This way, these tables can continue to receive partitioning information and also perform checks for the existence of tables, and support all SaveModes.
### Why are the changes needed?

write API.

### What changes were proposed in this pull request?
This pr is to propagate all the SQL configurations to executors in `SQLQueryTestSuite`. When the propagation enabled in the tests, a potential bug below becomes apparent;
```
CREATE TABLE num_data (id int, val decimal(38,10)) USING parquet;
....
select sum(udf(CAST(null AS Decimal(38,0)))) from range(1,4): QueryOutput(select sum(udf(CAST(null AS Decimal(38,0)))) from range(1,4),struct<>,java.lang.IllegalArgumentException
[info] requirement failed: MutableProjection cannot use UnsafeRow for output data types: decimal(38,0)) (SQLQueryTestSuite.scala:380)
```
The root culprit is that `InterpretedMutableProjection` has incorrect validation in the interpreter mode: `validExprs.forall { case (e, _) => UnsafeRow.isFixedLength(e.dataType) }`. This validation should be the same with the condition (`isMutable`) in `HashAggregate.supportsAggregate`: https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/HashAggregateExec.scala#L1126

This is a follow-up of the [review comment](https://github.com/apache/spark/pull/25706#discussion_r321923311).
This patch unifies the default wait time to be 10 seconds as it would fit most of UTs (as they have smaller timeouts) and doesn't bring additional latency since it will return if the condition is met.
This patch doesn't touch the one which waits 100000 milliseconds (100 seconds), to not break anything unintentionally, though I'd rather questionable that we really need to wait for 100 seconds.
### Why are the changes needed?
It simplifies the test code and get rid of various heuristic values on timeout.

## What changes were proposed in this pull request?
This adds a new write API as proposed in the [SPIP to standardize logical plans](https://issues.apache.org/jira/browse/SPARK-23521). This new API:
* Uses clear verbs to execute writes, like `append`, `overwrite`, `create`, and `replace` that correspond to the new logical plans.
* Only creates v2 logical plans so the behavior is always consistent.
* Does not allow table configuration options for operations that cannot change table configuration. For example, `partitionedBy` can only be called when the writer executes `create` or `replace`.
Here are a few example uses of the new API:
```scala
df.writeTo("catalog.db.table").append()
df.writeTo("catalog.db.table").overwrite($"date" === "2019-06-01")
df.writeTo("catalog.db.table").overwritePartitions()
df.writeTo("catalog.db.table").asParquet.create()
df.writeTo("catalog.db.table").partitionedBy(days($"ts")).createOrReplace()
df.writeTo("catalog.db.table").using("abc").replace()
```
## How was this patch tested?
Added `DataFrameWriterV2Suite` that tests the new write API. Existing tests for v2 plans.

This situation can happen when an external system (e.g. Oozie) generates
delegation tokens for a Spark application. The Spark driver will then run
against secured services, have proper credentials (the tokens), but no
kerberos credentials. So trying to do things that requires a kerberos
credential fails.
Instead, if no kerberos credentials are detected, just skip the whole
delegation token code.
Tested with an application that simulates Oozie; fails before the fix,
passes with the fix. Also with other DT-related tests to make sure other
functionality keeps working.

## What changes were proposed in this pull request?
This proposes to improve Spark instrumentation by adding a hook for user-defined metrics, extending Spark’s Dropwizard/Codahale metrics system.
The original motivation of this work was to add instrumentation for S3 filesystem access metrics by Spark job. Currently, [[ExecutorSource]] instruments HDFS and local filesystem metrics. Rather than extending the code there, we proposes with this JIRA to add a metrics plugin system which is of more flexible and general use.
Context: The Spark metrics system provides a large variety of metrics, see also , useful to monitor and troubleshoot Spark workloads. A typical workflow is to sink the metrics to a storage system and build dashboards on top of that.
Highlights:
- The metric plugin system makes it easy to implement instrumentation for S3 access by Spark jobs.
- The metrics plugin system allows for easy extensions of how Spark collects HDFS-related workload metrics. This is currently done using the Hadoop Filesystem GetAllStatistics method, which is deprecated in recent versions of Hadoop. Recent versions of Hadoop Filesystem recommend using method GetGlobalStorageStatistics, which also provides several additional metrics. GetGlobalStorageStatistics is not available in Hadoop 2.7 (had been introduced in Hadoop 2.8). Using a metric plugin for Spark would allow an easy way to “opt in” using such new API calls for those deploying suitable Hadoop versions.
- We also have the use case of adding Hadoop filesystem monitoring for a custom Hadoop compliant filesystem in use in our organization (EOS using the XRootD protocol). The metrics plugin infrastructure makes this easy to do. Others may have similar use cases.
- More generally, this method makes it straightforward to plug in Filesystem and other metrics to the Spark monitoring system. Future work on plugin implementation can address extending monitoring to measure usage of external resources (OS, filesystem, network, accelerator cards, etc), that maybe would not normally be considered general enough for inclusion in Apache Spark code, but that can be nevertheless useful for specialized use cases, tests or troubleshooting.
Implementation:
The proposed implementation extends and modifies the work on Executor Plugin of SPARK-24918. Additionally, this is related to recent work on extending Spark executor metrics, such as SPARK-25228.
As discussed during the review, the implementaiton of this feature modifies the Developer API for Executor Plugins, such that the new version is incompatible with the original version in Spark 2.4.
## How was this patch tested?
This modifies existing tests for ExecutorPluginSuite to adapt them to the API changes. In addition, the new funtionality for registering pluginMetrics has been manually tested running Spark on YARN and K8S clusters, in particular for monitoring S3 and for extending HDFS instrumentation with the Hadoop Filesystem “GetGlobalStorageStatistics” metrics. Executor metric plugin example and code used for testing are available, for example at: https://github.com/cerndb/SparkExecutorPluginsCloses#24901 from LucaCanali/executorMetricsPlugin.
