Gengliang Wang e39e97b73a [SPARK-27699][SQL] Partially push down disjunctive predicated in Parquet/ORC
## What changes were proposed in this pull request?

Currently, in `ParquetFilters` and `OrcFilters`, if the child predicate of `Or` operator can't be entirely pushed down, the predicates will be thrown away.
In fact, the conjunctive predicates under `Or` operators can be partially pushed down.
For example, says `a` and `b` are convertible, while `c` can't be pushed down, the predicate
`a or (b and c)`
can be converted as
`(a or b) and (a or c)`
We can still push down `(a or b)`.
We can't push down disjunctive predicates only when one of its children is not partially convertible.

This PR also improve the filter pushing down logic in `DataSourceV2Strategy`. With partial filter push down in `Or` operator, the result of `pushedFilters()` might not exist in the mapping `translatedFilterToExpr`.  To fix it, this PR changes the mapping `translatedFilterToExpr` as leaf filter expression to `sources.filter`, and later on rebuild the whole expression with the mapping.

Kazuaki Ishizaki 9e0d8c6ce2 [SPARK-27752][CORE] Upgrade lz4-java from 1.5.1 to 1.6.0
## What changes were proposed in this pull request?

This PR upgrades lz4-java from 1.5.1 to 1.6.0. Lz4-java is available at https://github.com/lz4/lz4-java.

Changes from 1.5.1:
- Upgraded LZ4 to 1.9.1. Updated the JNI bindings, except for the one for Linux/i386. Decompression speed is improved on amd64.
- Deprecated use of LZ4FastDecompressor of a native instance because the corresponding C API function is deprecated. See the release note of LZ4 1.9.0 for details. Updated javadoc accordingly.
- Changed the module name from org.lz4.lz4-java to org.lz4.java to avoid using - in the module name. (severn-everett, Oliver Eikemeier, Rei Odaira)
- Enabled build with Java 11. Note that the distribution is still built with Java 7. (Rei Odaira)

Wenchen Fan fc5bd6da77 [SPARK-27576][SQL] table capability to skip the output column resolution
## What changes were proposed in this pull request?

Currently we have an analyzer rule, which resolves the output columns of data source v2 writing plans, to make sure the schema of input query is compatible with the table.

However, not all data sources need this check. For example, the `NoopDataSource` doesn't care about the schema of input query at all.

This PR introduces a new table capability: ACCEPT_ANY_SCHEMA. If a table reports this capability, we skip resolving output columns for it during write.

Note that, we already skip resolving output columns for `NoopDataSource` because it implements `SupportsSaveMode`. However, `SupportsSaveMode` is a hack and will be removed soon.

## What changes were proposed in this pull request?

When we upgraded the built-in Hive to 2.3.4, the current `hive-thriftserver` module is not compatible, such as these Hive changes:
1. [HIVE-12442](https://issues.apache.org/jira/browse/HIVE-12442) HiveServer2: Refactor/repackage HiveServer2's Thrift code so that it can be used in the tasks
2. [HIVE-12237](https://issues.apache.org/jira/browse/HIVE-12237) Use slf4j as logging facade
3. [HIVE-13169](https://issues.apache.org/jira/browse/HIVE-13169) HiveServer2: Support delegation token based connection when using http transport

So this PR moves the incompatible code to `sql/hive-thriftserver/v1.2.1` and copies it to `sql/hive-thriftserver/v2.3.4` for the next code review.

Marcelo Vanzin d14e2d7874 [SPARK-27678][UI] Allow user impersonation in the UI.
This feature allows proxy servers to identify the actual request user
using a request parameter, and performs access control checks against
that user instead of the authenticated user. Impersonation is only
allowed if the authenticated user is configured as an admin.

The request parameter used ("doAs") matches the one currently used by
Knox, but it should be easy to change / customize if different proxy
servers use a different way of identifying the original user.

Tested with updated unit tests and also with a live server behind Knox.

pgandhi 695dbe27ce [SPARK-25719][UI] : Search functionality in datatables in stages page should search over formatted data rather than the raw data
The Pull Request to add datatables to stage page SPARK-21809 got merged. The search functionality in those datatables being a great improvement for searching through a large number of tasks, also performs search over the raw data rather than the formatted data displayed in the tables. It would be great if the search can happen for the formatted data as well.

## What changes were proposed in this pull request?

Added code to enable searching over displayed data in tables e.g. searching on "165.7 MiB" or "0.3 ms" will now return the search results. Also, earlier we were missing search for two columns in the task table "Shuffle Read Bytes" as well as "Shuffle Remote Reads", which I have added here.

Thomas Graves db2e3c4341 [SPARK-27024] Executor interface for cluster managers to support GPU and other resources
## What changes were proposed in this pull request?

Add in GPU and generic resource type allocation to the executors.

Note this is part of a bigger feature for gpu-aware scheduling and is just how the executor find the resources. The general flow :

   - users ask for a certain set of resources, for instance number of gpus - each cluster manager has a specific way to do this.
  -  cluster manager allocates a container or set of resources (standalone mode)
-    When spark launches the executor in that container, the executor either has to be told what resources it has or it has to auto discover them.
  -  Executor has to register with Driver and tell the driver the set of resources it has so the scheduler can use that to schedule tasks that requires a certain amount of each of those resources

In this pr I added configs and arguments to the executor to be able discover resources. The argument to the executor is intended to be used by standalone mode or other cluster managers that don't have isolation so that it can assign specific resources to specific executors in case there are multiple executors on a node. The argument is a file contains JSON Array of ResourceInformation objects.

The discovery script is meant to be used in an isolated environment where the executor only sees the resources it should use.

Note that there will be follow on PRs to add other parts like the scheduler part. See the epic high level jira: https://issues.apache.org/jira/browse/SPARK-24615

## How was this patch tested?

Added unit tests and manually tested.

mingbo.pb 66f5a42ca5 [SPARK-27638][SQL] Cast string to date/timestamp in binary comparisons with dates/timestamps
## What changes were proposed in this pull request?

The below example works with both Mysql and Hive, however not with spark.

```
mysql> select * from date_test where date_col >= '2000-1-1';
+------------+
| date_col   |
+------------+
| 2000-01-01 |
+------------+
```
The reason is that Spark casts both sides to String type during date and string comparison for partial date support. Please find more details in https://issues.apache.org/jira/browse/SPARK-8420.

Based on some tests, the behavior of Date and String comparison in Hive and Mysql:
Hive: Cast to Date, partial date is not supported
Mysql: Cast to Date, certain "partial date" is supported by defining certain date string parse rules. Check out str_to_datetime in https://github.com/mysql/mysql-server/blob/5.5/sql-common/my_time.c

As below date patterns have been supported, the PR is to cast string to date when comparing string and date:
```
`yyyy`
`yyyy-[m]m`
`yyyy-[m]m-[d]d`
`yyyy-[m]m-[d]d `
`yyyy-[m]m-[d]d *`
`yyyy-[m]m-[d]dT*

Liang-Chi Hsieh 8b0bdaa8e0 [SPARK-27671][SQL] Fix error when casting from a nested null in a struct
## What changes were proposed in this pull request?

When a null in a nested field in struct, casting from the struct throws error, currently.

```scala
scala> sql("select cast(struct(1, null) as struct<a:int,b:int>)").show
scala.MatchError: NullType (of class org.apache.spark.sql.types.NullType$)
  at org.apache.spark.sql.catalyst.expressions.Cast.castToInt(Cast.scala:447)
  at org.apache.spark.sql.catalyst.expressions.Cast.cast(Cast.scala:635)
  at org.apache.spark.sql.catalyst.expressions.Cast.$anonfun$castStruct$1(Cast.scala:603)
```

Similarly, inline table, which casts null in nested field under the hood, also throws an error.

```scala
scala> sql("select * FROM VALUES (('a', (10, null))), (('b', (10, 50))), (('c', null)) AS tab(x, y)").show
org.apache.spark.sql.AnalysisException: failed to evaluate expression named_struct('col1', 10, 'col2', NULL): NullType (of class org.apache.spark.sql.t

    val threadFactory = namedThreadFactory(prefix)
    val threadPool = new ThreadPoolExecutor(
      maxThreadNumber, // corePoolSize: the max number of threads to create before queuing the tasks
      maxThreadNumber, // maximumPoolSize: because we use LinkedBlockingDeque, this one is not used

ryne.yang dbb8143501 [MINOR][SS][DOC] Added missing config maxFileAge in file streaming source
## What changes were proposed in this pull request?

added the missing config for structured streaming when using file source.

from the code we have
```
  /**
   * Maximum age of a file that can be found in this directory, before it is ignored. For the
   * first batch all files will be considered valid. If `latestFirst` is set to `true` and
   * `maxFilesPerTrigger` is set, then this parameter will be ignored, because old files that are
   * valid, and should be processed, may be ignored. Please refer to SPARK-19813 for details.
   *
   * The max age is specified with respect to the timestamp of the latest file, and not the
   * timestamp of the current system. That this means if the last file has timestamp 1000, and the
   * current system time is 2000, and max age is 200, the system will purge files older than
   * 800 (rather than 1800) from the internal state.
   *
   * Default to a week.
   */
  val maxFileAgeMs: Long =
    Utils.timeStringAsMs(parameters.getOrElse("maxFileAge", "7d"))
```
which is not documented.

also the file processing order was not mentioned but in the code we specifically select the file list based on file mtime:
```scala
private val fileSortOrder = if (sourceOptions.latestFirst) {
      logWarning(
        """'latestFirst' is true. New files will be processed first, which may affect the watermark
          |value. In addition, 'maxFileAge' will be ignored.""".stripMargin)
      implicitly[Ordering[Long]].reverse
    } else {
      implicitly[Ordering[Long]]
    }

val files = allFiles.sortBy(_.getModificationTime)(fileSortOrder).map { status =>
      (status.getPath.toUri.toString, status.getModificationTime)
    }
```

Sam Tran bcd3b61c4b [SPARK-27347][MESOS] Fix supervised driver retry logic for outdated tasks
## What changes were proposed in this pull request?

This patch fixes a bug where `--supervised` Spark jobs would retry multiple times whenever an agent would crash, come back, and re-register even when those jobs had already relaunched on a different agent.

That is:
```
- supervised driver is running on agent1
- agent1 crashes
- driver is relaunched on another agent as `<task-id>-retry-1`
- agent1 comes back online and re-registers with scheduler
- spark relaunches the same job as `<task-id>-retry-2`
- now there are two jobs running simultaneously
```

This is because when an agent would come back and re-register it would send a status update `TASK_FAILED` for its old driver-task. Previous logic would indiscriminately remove the `submissionId` from Zookeeper's `launchedDrivers` node and add it to `retryList` node. Then, when a new offer came in, it would relaunch another `-retry-`  task even though one was previously running.

For example logs, scroll to bottom

## How was this patch tested?

- Added a unit test to simulate behavior described above
- Tested manually on a DC/OS cluster by
  ```
  - launching a --supervised spark job
  - dcos node ssh <to the agent with the running spark-driver>
  - systemctl stop dcos-mesos-slave
  - docker kill <driver-container-id>
  - [ wait until spark job is relaunched ]
  - systemctl start dcos-mesos-slave
  - [ observe spark driver is not relaunched as `-retry-2` ]
  ```

Log snippets included below. Notice the `-retry-1` task is running when status update for the old task comes in afterward:

jiafu.zhang@intel.com fa5dc0a45a [SPARK-26632][CORE] Separate Thread Configurations of Driver and Executor
## What changes were proposed in this pull request?

For the below three thread configuration items applied to both driver and executor,
spark.rpc.io.serverThreads
spark.rpc.io.clientThreads
spark.rpc.netty.dispatcher.numThreads,
we separate them to driver specifics and executor specifics.
spark.driver.rpc.io.serverThreads                     < - > spark.executor.rpc.io.serverThreads
spark.driver.rpc.io.clientThreads                      < - > spark.executor.rpc.io.clientThreads
spark.driver.rpc.netty.dispatcher.numThreads < - > spark.executor.rpc.netty.dispatcher.numThreads

Spark reads these specifics first and fall back to the common configurations.

## How was this patch tested?
We ran the SimpleMap app without shuffle for benchmark purpose to test Spark's scalability in HPC with omini-path NIC which has higher bandwidth than normal ethernet NIC.

Spark's base version is 2.4.0.
Spark ran in the Standalone mode. Driver was in a standalone node.
After the separation, the performance is improved a lot in 256 nodes and 512 nodes. see below test results of SimpleMapTask before and after the enhancement. You can view the tables in the  [JIRA](https://issues.apache.org/jira/browse/SPARK-26632) too.

dd: spark.driver.rpc.netty.dispatcher.numThreads

                                    (1L,2L,1.0),
                                    (3L, 4L,1.0),
                                    (4L,0L,0.1))).toDF("src", "dst", "weight")

val model = new PowerIterationClustering().
                           setMaxIter(10).
                           setInitMode("degree").
                          setWeightCol("weight")

val prediction = model.assignClusters(dataset).select("id", "cluster")
```

2) Open storage tab of the UI. We can see many RDD block cached, even after running the PIC.

In this PR, basically materializes the new graph before unpersisting the old ones.

pgandhi 0969d7aa0c [SPARK-27207][SQL] : Ensure aggregate buffers are initialized again for So…
…rtBasedAggregate

Normally, the aggregate operations that are invoked for an aggregation buffer for User Defined Aggregate Functions(UDAF) follow the order like initialize(), update(), eval() OR initialize(), merge(), eval(). However, after a certain threshold configurable by spark.sql.objectHashAggregate.sortBased.fallbackThreshold is reached, ObjectHashAggregate falls back to SortBasedAggregator which invokes the merge or update operation without calling initialize() on the aggregate buffer.

## What changes were proposed in this pull request?

The fix here is to initialize aggregate buffers again when fallback to SortBasedAggregate operator happens.

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 bae5baae52 [SPARK-27642][SS] make v1 offset extends v2 offset
## What changes were proposed in this pull request?

To move DS v2 to the catalyst module, we can't make v2 offset rely on v1 offset, as v1 offset is in sql/core.

## How was this patch tested?

existing tests

Xingbo Jiang e63fbfcf20 [SPARK-25139][SPARK-18406][CORE] Avoid NonFatals to kill the Executor in PythonRunner
## What changes were proposed in this pull request?

Python uses a prefetch approach to read the result from upstream and serve them in another thread, thus it's possible that if the children operator doesn't consume all the data then the Task cleanup may happen before Python side read process finishes, this in turn create a race condition that the block read locks are freed during Task cleanup and then the reader try to release the read lock it holds and find it has been released, in this case we shall hit a AssertionError.

We shall catch the AssertionError in PythonRunner and prevent this kill the Executor.

## How was this patch tested?

Hard to write a unit test case for this case, manually verified with failed job.

Closes #24542 from jiangxb1987/pyError.

Ryan Blue 303ee3fce0 [SPARK-24252][SQL] Add TableCatalog API
## What changes were proposed in this pull request?

This adds the TableCatalog API proposed in the [Table Metadata API SPIP](https://docs.google.com/document/d/1zLFiA1VuaWeVxeTDXNg8bL6GP3BVoOZBkewFtEnjEoo/edit#heading=h.m45webtwxf2d).

For `TableCatalog` to use `Table`, it needed to be moved into the catalyst module where the v2 catalog API is located. This also required moving `TableCapability`. Most of the files touched by this PR are import changes needed by this move.

## How was this patch tested?

This adds a test implementation and contract tests.

Bryan Cutler 5e79ae3b40 [SPARK-23961][SPARK-27548][PYTHON] Fix error when toLocalIterator goes out of scope and properly raise errors from worker
## What changes were proposed in this pull request?

This fixes an error when a PySpark local iterator, for both RDD and DataFrames, goes out of scope and the connection is closed before fully consuming the iterator. The error occurs on the JVM in the serving thread, when Python closes the local socket while the JVM is writing to it. This usually happens when there is enough data to fill the socket read buffer, causing the write call to block.

Additionally, this fixes a problem when an error occurs in the Python worker and the collect job is cancelled with an exception. Previously, the Python driver was never notified of the error so the user could get a partial result (iteration until the error) and the application will continue. With this change, an error in the worker is sent to the Python iterator and is then raised.

The change here introduces a protocol for PySpark local iterators that work as follows:

1) The local socket connection is made when the iterator is created
2) When iterating, Python first sends a request for partition data as a non-zero integer
3) While the JVM local iterator over partitions has next, it triggers a job to collect the next partition
4) The JVM sends a nonzero response to indicate it has the next partition to send
5) The next partition is sent to Python and read by the PySpark deserializer
6) After sending the entire partition, an `END_OF_DATA_SECTION` is sent to Python which stops the deserializer and allows to make another request
7) When the JVM gets a request from Python but has already consumed it's local iterator, it will send a zero response to Python and both will close the socket cleanly
8) If an error occurs in the worker, a negative response is sent to Python followed by the error message. Python will then raise a RuntimeError with the message, stopping iteration.
9) When the PySpark local iterator is garbage-collected, it will read any remaining data from the current partition (this is data that has already been collected) and send a request of zero to tell the JVM to stop collection jobs and close the connection.

Steps 1, 3, 5, 6 are the same as before. Step 8 was completely missing before because errors in the worker were never communicated back to Python. The other steps add synchronization to allow for a clean closing of the socket, with a small trade-off in performance for each partition. This is mainly because the JVM does not start collecting partition data until it receives a request to do so, where before it would eagerly write all data until the socket receive buffer is full.

## How was this patch tested?

Added new unit tests for DataFrame and RDD `toLocalIterator` and tested not fully consuming the iterator. Manual tests with Python 2.7  and 3.6.

Closes #24070 from BryanCutler/pyspark-toLocalIterator-clean-stop-SPARK-23961.
