HyukjinKwon db48da87f0 [SPARK-27834][SQL][R][PYTHON] Make separate PySpark/SparkR vectorization configurations
## What changes were proposed in this pull request?

`spark.sql.execution.arrow.enabled` was added when we add PySpark arrow optimization.
Later, in the current master, SparkR arrow optimization was added and it's controlled by the same configuration `spark.sql.execution.arrow.enabled`.

There look two issues about this:

1. `spark.sql.execution.arrow.enabled` in PySpark was added from 2.3.0 whereas SparkR optimization was added 3.0.0. The stability is different so it's problematic when we change the default value for one of both optimization first.

2. Suppose users want to share some JVM by PySpark and SparkR. They are currently forced to use the optimization for all or none if the configuration is set globally.

This PR proposes two separate configuration groups for PySpark and SparkR about Arrow optimization:

- Deprecate `spark.sql.execution.arrow.enabled`
- Add `spark.sql.execution.arrow.pyspark.enabled` (fallback to `spark.sql.execution.arrow.enabled`)
- Add `spark.sql.execution.arrow.sparkr.enabled`
- Deprecate `spark.sql.execution.arrow.fallback.enabled`
- Add `spark.sql.execution.arrow.pyspark.fallback.enabled ` (fallback to `spark.sql.execution.arrow.fallback.enabled`)

Note that `spark.sql.execution.arrow.maxRecordsPerBatch` is used within JVM side for both.
Note that `spark.sql.execution.arrow.fallback.enabled` was added due to behaviour change. We don't need it in SparkR - SparkR side has the automatic fallback.

## How was this patch tested?

Manually tested and some unittests were added.

Closes #24700 from HyukjinKwon/separate-sparkr-arrow.

## What changes were proposed in this pull request?

Documentation has an error, https://spark.apache.org/docs/latest/sql-data-sources-hive-tables.html#hive-tables.

The example:

scala> spark.range(10).write.parquet(dataDir)

scala> sql(s"CREATE EXTERNAL TABLE hive_ints(key int) STORED AS PARQUET LOCATION '$dataDir'")
res6: org.apache.spark.sql.DataFrame = []

scala> sql("SELECT * FROM hive_ints").show()

Gengliang Wang 78a403fab9 [SPARK-27627][SQL] Make option "pathGlobFilter" as a general option for all file sources
## What changes were proposed in this pull request?

### Background:
The data source option `pathGlobFilter` is introduced for Binary file format: https://github.com/apache/spark/pull/24354 , which can be used for filtering file names, e.g. reading `.png` files only while there is `.json` files in the same directory.

### Proposal:
Make the option `pathGlobFilter` as a general option for all file sources. The path filtering should happen in the path globbing on Driver.

### Motivation:
Filtering the file path names in file scan tasks on executors is kind of ugly.

### Impact:
1. The splitting of file partitions will be more balanced.
2. The metrics of file scan will be more accurate.
3. Users can use the option for reading other file sources.

## How was this patch tested?

Wenchen Fan 8656af98c0 [SPARK-26861][SQL] deprecate typed sum/count/average
## What changes were proposed in this pull request?

These builtin typed aggregate functions are not very useful:
1. users can just call the untyped ones and turn the resulting dataframe to a dataset. It has better performance.
2. the typed aggregate functions have subtle different behaviors regarding empty input.

I think we should get rid of these builtin typed agg functions and suggest users to use the untyped ones.

However, these functions are still useful as a demo of the `Aggregator` API, so I copied them to the example module.

Maxim Gekk a829234df3 [SPARK-26817][CORE] Use System.nanoTime to measure time intervals
## What changes were proposed in this pull request?

In the PR, I propose to use `System.nanoTime()` instead of `System.currentTimeMillis()` in measurements of time intervals.

`System.currentTimeMillis()` returns current wallclock time and will follow changes to the system clock. Thus, negative wallclock adjustments can cause timeouts to "hang" for a long time (until wallclock time has caught up to its previous value again). This can happen when ntpd does a "step" after the network has been disconnected for some time. The most canonical example is during system bootup when DHCP takes longer than usual. This can lead to failures that are really hard to understand/reproduce. `System.nanoTime()` is guaranteed to be monotonically increasing irrespective of wallclock changes.

## How was this patch tested?

By existing test suites.

Sean Owen 722369ee55 [SPARK-24421][BUILD][CORE] Accessing sun.misc.Cleaner in JDK11
…. Other related changes to get JDK 11 working, to test

## What changes were proposed in this pull request?

- Access `sun.misc.Cleaner` (Java 8) and `jdk.internal.ref.Cleaner` (JDK 9+) by reflection (note: the latter only works if illegal reflective access is allowed)
- Access `sun.misc.Unsafe.invokeCleaner` in Java 9+ instead of `sun.misc.Cleaner` (Java 8)

In order to test anything on JDK 11, I also fixed a few small things, which I include here:

- Fix minor JDK 11 compile issues
- Update scala plugin, Jetty for JDK 11, to facilitate tests too

This doesn't mean JDK 11 tests all pass now, but lots do. Note also that the JDK 9+ solution for the Cleaner has a big caveat.

## How was this patch tested?

Existing tests. Manually tested JDK 11 build and tests, and tests covering this change appear to pass. All Java 8 tests should still pass, but this change alone does not achieve full JDK 11 compatibility.

Huangweizhe 6c66ab8b33 [SPARK-24688][EXAMPLES] Modify the comments about LabeledPoint
## What changes were proposed in this pull request?

An RDD is created using LabeledPoint, but the comment is like #LabeledPoint(feature, label).
Although in the method ChiSquareTest.test, the second parameter is feature and the third parameter is label, it it better to write label in front of feature here because if an RDD is created using LabeldPoint, what we get are actually (label, feature) pairs.
Now it is changed as LabeledPoint(label, feature).

The comments in Scala and Java example have the same typos.

jerryshao 5fccdae189 [SPARK-22968][DSTREAM] Throw an exception on partition revoking issue
## What changes were proposed in this pull request?

Kafka partitions can be revoked when new consumers joined in the consumer group to rebalance the partitions. But current Spark Kafka connector code makes sure there's no partition revoking scenarios, so trying to get latest offset from revoked partitions will throw exceptions as JIRA mentioned.

Partition revoking happens when new consumer joined the consumer group, which means different streaming apps are trying to use same group id. This is fundamentally not correct, different apps should use different consumer group. So instead of throwing an confused exception from Kafka, improve the exception message by identifying revoked partition and directly throw an meaningful exception when partition is revoked.

Besides, this PR also fixes bugs in `DirectKafkaWordCount`, this example simply cannot be worked without the fix.

```
8/01/05 09:48:27 INFO internals.ConsumerCoordinator: Revoking previously assigned partitions [kssh-7, kssh-4, kssh-3, kssh-6, kssh-5, kssh-0, kssh-2, kssh-1] for group use_a_separate_group_id_for_each_stream

```

## How was this patch tested?

This is manually verified in local cluster, unfortunately I'm not sure how to simulate it in UT, so propose the PR without UT added.
