…ss NFS directories ## What changes were proposed in this pull request? Change from using java Files.move to use Hadoop filesystem operations to move the directories. The java Files.move does not work when moving directories across NFS mounts and in fact also says that if the directory has entries you should do a recursive move. We are already using Hadoop filesystem here so just use the local filesystem from there as it handles this properly. Note that the DB here is actually a directory of files and not just a single file, hence the change in the name of the local var. ## How was this patch tested? Ran YarnShuffleServiceSuite unit tests. Unfortunately couldn't easily add one here since involves NFS. Ran manual tests to verify that the DB directories were properly moved across NFS mounted directories. Have been running this internally for weeks. Author: Tom Graves <tgraves@apache.org> Closes #17748 from tgravescs/SPARK-19812.
## What changes were proposed in this pull request? Some PySpark & SparkR tests run with tiny dataset and tiny ```maxIter```, which means they are not converged. I don’t think checking intermediate result during iteration make sense, and these intermediate result may vulnerable and not stable, so we should switch to check the converged result. We hit this issue at #17746 when we upgrade breeze to 0.13.1. ## How was this patch tested? Existing tests. Author: Yanbo Liang <ybliang8@gmail.com> Closes #17757 from yanboliang/flaky-test.
## What changes were proposed in this pull request? This is a follow-up of #14617 to make the name of memory related fields more meaningful. Here for the backward compatibility, I didn't change `maxMemory` and `memoryUsed` fields. ## How was this patch tested? Existing UT and local verification. CC squito and tgravescs . Author: jerryshao <sshao@hortonworks.com> Closes #17700 from jerryshao/SPARK-20391.
## What changes were proposed in this pull request? ColumnVector implementations originally did not support some Catalyst types (float, short, and boolean). Now that they do, those types should be also added to the ColumnVector.Array. ## How was this patch tested? Tested using existing unit tests. Author: Michal Szafranski <michal@databricks.com> Closes #17772 from michal-databricks/spark-20473.
## What changes were proposed in this pull request? OnHeapColumnVector reallocation copies to the new storage data up to 'elementsAppended'. This variable is only updated when using the ColumnVector.appendX API, while ColumnVector.putX is more commonly used. ## How was this patch tested? Tested using existing unit tests. Author: Michal Szafranski <michal@databricks.com> Closes #17773 from michal-databricks/spark-20474.
## What changes were proposed in this pull request? Spark 2.2 is going to be cut, it'll be great if SPARK-12868 can be resolved before that. There have been several PRs for this like [PR#16324](#16324) , but all of them are inactivity for a long time or have been closed. This PR added a SparkUrlStreamHandlerFactory, which relies on 'protocol' to choose the appropriate UrlStreamHandlerFactory like FsUrlStreamHandlerFactory to create URLStreamHandler. ## How was this patch tested? 1. Add a new unit test. 2. Check manually. Before: throw an exception with " failed unknown protocol: hdfs" <img width="914" alt="screen shot 2017-03-17 at 9 07 36 pm" src="https://cloud.githubusercontent.com/assets/8546874/24075277/5abe0a7c-0bd5-11e7-900e-ec3d3105da0b.png"> After: <img width="1148" alt="screen shot 2017-03-18 at 11 42 18 am" src="https://cloud.githubusercontent.com/assets/8546874/24075283/69382a60-0bd5-11e7-8d30-d9405c3aaaba.png"> Author: Weiqing Yang <yangweiqing001@gmail.com> Closes #17342 from weiqingy/SPARK-18910.
This change does a more thorough redaction of sensitive information from logs and UI Add unit tests that ensure that no regressions happen that leak sensitive information to the logs. The motivation for this change was appearance of password like so in `SparkListenerEnvironmentUpdate` in event logs under some JVM configurations: `"sun.java.command":"org.apache.spark.deploy.SparkSubmit ... --conf spark.executorEnv.HADOOP_CREDSTORE_PASSWORD=secret_password ..." ` Previously redaction logic was only checking if the key matched the secret regex pattern, it'd redact it's value. That worked for most cases. However, in the above case, the key (sun.java.command) doesn't tell much, so the value needs to be searched. This PR expands the check to check for values as well. ## How was this patch tested? New unit tests added that ensure that no sensitive information is present in the event logs or the yarn logs. Old unit test in UtilsSuite was modified because the test was asserting that a non-sensitive property's value won't be redacted. However, the non-sensitive value had the literal "secret" in it which was causing it to redact. Simply updating the non-sensitive property's value to another arbitrary value (that didn't have "secret" in it) fixed it. Author: Mark Grover <mark@apache.org> Closes #17725 from markgrover/spark-20435.

…or its output partitioning
### What changes were proposed in this pull request?
Currently, the `BroadcastHashJoinExec`'s `outputPartitioning` only uses the streamed side's `outputPartitioning`. However, if the join type of `BroadcastHashJoinExec` is an inner-like join, the build side's info (the join keys) can be added to `BroadcastHashJoinExec`'s `outputPartitioning`.
For example,
```Scala
spark.conf.set("spark.sql.autoBroadcastJoinThreshold", "500")
val t1 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i1", "j1")
val t2 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i2", "j2")
val t3 = (0 until 20).map(i => (i % 7, i % 11)).toDF("i3", "j3")
val t4 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i4", "j4")
// join1 is a sort merge join.
val join1 = t1.join(t2, t1("i1") === t2("i2"))
// join2 is a broadcast join where t3 is broadcasted.
val join2 = join1.join(t3, join1("i1") === t3("i3"))
// Join on the column from the broadcasted side (i3).
val join3 = join2.join(t4, join2("i3") === t4("i4"))
join3.explain
```
You see that `Exchange hashpartitioning(i2#103, 200)` is introduced because there is no output partitioning info from the build side.
```
== Physical Plan ==
*(6) SortMergeJoin [i3#29], [i4#40], Inner
:- *(4) Sort [i3#29 ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(i3#29, 200), true, [id=#55]
: +- *(3) BroadcastHashJoin [i1#7], [i3#29], Inner, BuildRight

+- Exchange hashpartitioning(i4#40, 200), true, [id=#39]

```
This PR proposes to introduce output partitioning for the build side for `BroadcastHashJoinExec` if the streamed side has a `HashPartitioning` or a collection of `HashPartitioning`s.
There is a new internal config `spark.sql.execution.broadcastHashJoin.outputPartitioningExpandLimit`, which can limit the number of partitioning a `HashPartitioning` can expand to. It can be set to "0" to disable this feature.
### Why are the changes needed?
To remove unnecessary shuffle.
### Does this PR introduce _any_ user-facing change?
Yes, now the shuffle in the above example can be eliminated:
```
== Physical Plan ==
*(5) SortMergeJoin [i3#108], [i4#119], Inner
:- *(3) Sort [i3#108 ASC NULLS FIRST], false, 0
: +- *(3) BroadcastHashJoin [i1#86], [i3#108], Inner, BuildRight
: :- *(3) SortMergeJoin [i1#86], [i2#97], Inner
: : :- *(1) Sort [i1#86 ASC NULLS FIRST], false, 0
: : : +- Exchange hashpartitioning(i1#86, 200), true, [id=#120]
: : : +- LocalTableScan [i1#86, j1#87]
: : +- *(2) Sort [i2#97 ASC NULLS FIRST], false, 0
: : +- Exchange hashpartitioning(i2#97, 200), true, [id=#121]
: : +- LocalTableScan [i2#97, j2#98]
: +- BroadcastExchange HashedRelationBroadcastMode(List(cast(input[0, int, false] as bigint))), [id=#126]
: +- LocalTableScan [i3#108, j3#109]
+- *(4) Sort [i4#119 ASC NULLS FIRST], false, 0
+- Exchange hashpartitioning(i4#119, 200), true, [id=#130]
+- LocalTableScan [i4#119, j4#120]
```
### How was this patch tested?
Added new tests.
Closes apache#28676 from imback82/broadcast_join_output.

…onnect ### What changes were proposed in this pull request? Implement Arrow-optimized Python UDFs in Spark Connect. Please see apache#39384 for motivation and performance improvements of Arrow-optimized Python UDFs. ### Why are the changes needed? Parity with vanilla PySpark. ### Does this PR introduce _any_ user-facing change? Yes. In Spark Connect Python Client, users can: 1. Set `useArrow` parameter True to enable Arrow optimization for a specific Python UDF. ```sh >>> df = spark.range(2) >>> df.select(udf(lambda x : x + 1, useArrow=True)('id')).show() +------------+ |<lambda>(id)| +------------+ | 1| | 2| +------------+ # ArrowEvalPython indicates Arrow optimization >>> df.select(udf(lambda x : x + 1, useArrow=True)('id')).explain() == Physical Plan == *(2) Project [pythonUDF0#18 AS <lambda>(id)#16] +- ArrowEvalPython [<lambda>(id#14L)#15], [pythonUDF0#18], 200 +- *(1) Range (0, 2, step=1, splits=1) ``` 2. Enable `spark.sql.execution.pythonUDF.arrow.enabled` Spark Conf to make all Python UDFs Arrow-optimized. ```sh >>> spark.conf.set("spark.sql.execution.pythonUDF.arrow.enabled", True) >>> df.select(udf(lambda x : x + 1)('id')).show() +------------+ |<lambda>(id)| +------------+ | 1| | 2| +------------+ # ArrowEvalPython indicates Arrow optimization >>> df.select(udf(lambda x : x + 1)('id')).explain() == Physical Plan == *(2) Project [pythonUDF0#30 AS <lambda>(id)#28] +- ArrowEvalPython [<lambda>(id#26L)#27], [pythonUDF0#30], 200 +- *(1) Range (0, 2, step=1, splits=1) ``` ### How was this patch tested? Parity unit tests. Closes apache#40725 from xinrong-meng/connect_arrow_py_udf. Authored-by: Xinrong Meng <xinrong@apache.org> Signed-off-by: Hyukjin Kwon <gurwls223@apache.org>
