…ort configuration ## What changes were proposed in this pull request? After SPARK-10997, client mode Netty RpcEnv doesn't require to start server, so port configurations are not used any more, here propose to remove these two configurations: "spark.executor.port" and "spark.am.port". ## How was this patch tested? Existing UTs. Author: jerryshao <[email protected]> Closes #17866 from jerryshao/SPARK-20605.

The recommendForAll of MLLIB ALS is very slow. GC is a key problem of the current method. The task use the following code to keep temp result: val output = new Array[(Int, (Int, Double))](m*n) m = n = 4096 (default value, no method to set) so output is about 4k * 4k * (4 + 4 + 8) = 256M. This is a large memory and cause serious GC problem, and it is frequently OOM. Actually, we don't need to save all the temp result. Support we recommend topK (topK is about 10, or 20) product for each user, we only need 4k * topK * (4 + 4 + 8) memory to save the temp result. The Test Environment: 3 workers: each work 10 core, each work 30G memory, each work 1 executor. The Data: User 480,000, and Item 17,000 BlockSize: 1024 2048 4096 8192 Old method: 245s 332s 488s OOM This solution: 121s 118s 117s 120s The existing UT.

…ting the package of sql/core and sql/hive ## What changes were proposed in this pull request? So far, we do not drop all the cataloged objects after each package. Sometimes, we might hit strange test case errors because the previous test suite did not drop the cataloged/temporary objects (tables/functions/database). At least, we can first clean up the environment when completing the package of `sql/core` and `sql/hive`. ## How was this patch tested? N/A Author: Xiao Li <[email protected]> Closes #17908 from gatorsmile/reset.

… headerpage ## What changes were proposed in this pull request? Spark Version for a specific application is not displayed on the history page now. It should be nice to switch the spark version on the UI when we click on the specific application. Currently there seems to be way as SparkListenerLogStart records the application version. So, it should be trivial to listen to this event and provision this change on the UI. For Example <img width="1439" alt="screen shot 2017-04-06 at 3 23 41 pm" src="https://cloud.githubusercontent.com/assets/8295799/25092650/41f3970a-2354-11e7-9b0d-4646d0adeb61.png"> <img width="1399" alt="screen shot 2017-04-17 at 9 59 33 am" src="https://cloud.githubusercontent.com/assets/8295799/25092743/9f9e2f28-2354-11e7-9605-f2f1c63f21fe.png"> {"Event":"SparkListenerLogStart","Spark Version":"2.0.0"} (Please fill in changes proposed in this fix) Modified the SparkUI for History server to listen to SparkLogListenerStart event and extract the version and print it. ## How was this patch tested?

## What changes were proposed in this pull request? `ReplSuite.newProductSeqEncoder with REPL defined class` was flaky and throws OOM exception frequently. By analyzing the heap dump, we found the reason is that, in each test case of `ReplSuite`, we create a REPL instance, which creates a classloader and loads a lot of classes related to `SparkContext`. More details please see #17833 (comment). In this PR, we create a new test suite, `SingletonReplSuite`, which shares one REPL instances among all the test cases. Then we move most of the tests from `ReplSuite` to `SingletonReplSuite`, to avoid creating a lot of REPL instances and reduce memory footprint. ## How was this patch tested? test only change Author: Wenchen Fan <[email protected]> Closes #17844 from cloud-fan/flaky-test.
## What changes were proposed in this pull request? For some reason we don't have an API to register UserDefinedFunction as named UDF. It is a no brainer to add one, in addition to the existing register functions we have. ## How was this patch tested? Added a test case in UDFSuite for the new API. Author: Reynold Xin <[email protected]> Closes #17915 from rxin/SPARK-20674.
## What changes were proposed in this pull request? Simply moves `Trigger.java` to `src/main/java` from `src/main/scala` See #17219 ## How was this patch tested? Existing tests. Author: Sean Owen <[email protected]> Closes #17921 from srowen/SPARK-19876.2.
…hon version ## What changes were proposed in this pull request? Drop the hadoop distirbution name from the Python version (PEP440 - https://www.python.org/dev/peps/pep-0440/). We've been using the local version string to disambiguate between different hadoop versions packaged with PySpark, but PEP0440 states that local versions should not be used when publishing up-stream. Since we no longer make PySpark pip packages for different hadoop versions, we can simply drop the hadoop information. If at a later point we need to start publishing different hadoop versions we can look at make different packages or similar. ## How was this patch tested? Ran `make-distribution` locally Author: Holden Karau <[email protected]> Closes #17885 from holdenk/SPARK-20627-remove-pip-local-version-string.

### What changes were proposed in this pull request? 1. Make more expressions extend `NullIntolerant`. 2. Add a checker(in `ExpressionInfoSuite`) to identify whether the expression is `NullIntolerant`. ### Why are the changes needed? Avoid skew join if the join column has many null values and can improve query performance. For examples: ```sql CREATE TABLE t1(c1 string, c2 string) USING parquet; CREATE TABLE t2(c1 string, c2 string) USING parquet; EXPLAIN SELECT t1.* FROM t1 JOIN t2 ON upper(t1.c1) = upper(t2.c1); ``` Before and after this PR: ```sql == Physical Plan == *(2) Project [c1#5, c2#6] +- *(2) BroadcastHashJoin [upper(c1#5)], [upper(c1#7)], Inner, BuildLeft :- BroadcastExchange HashedRelationBroadcastMode(List(upper(input[0, string, true]))), [id=#41] : +- *(1) ColumnarToRow : +- FileScan parquet default.t1[c1#5,c2#6] +- *(2) ColumnarToRow +- FileScan parquet default.t2[c1#7] == Physical Plan == *(2) Project [c1#5, c2#6] +- *(2) BroadcastHashJoin [upper(c1#5)], [upper(c1#7)], Inner, BuildRight :- *(2) Project [c1#5, c2#6] : +- *(2) Filter isnotnull(c1#5) : +- *(2) ColumnarToRow : +- FileScan parquet default.t1[c1#5,c2#6] +- BroadcastExchange HashedRelationBroadcastMode(List(upper(input[0, string, true]))), [id=#59] +- *(1) Project [c1#7] +- *(1) Filter isnotnull(c1#7) +- *(1) ColumnarToRow +- FileScan parquet default.t2[c1#7] ``` ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Unit test. Closes apache#28626 from wangyum/SPARK-28481. Authored-by: Yuming Wang <[email protected]> Signed-off-by: Wenchen Fan <[email protected]>

Optimize the TransposeWindow rule to extend applicable cases and optimize time complexity.
TransposeWindow rule will try to eliminate unnecessary shuffle:
but the function compatiblePartitions will only take the first n elements of the window2 partition sequence, for some cases, this will not take effect, like the case below:
val df = spark.range(10).selectExpr("id AS a", "id AS b", "id AS c", "id AS d")
df.selectExpr(
"sum(`d`) OVER(PARTITION BY `b`,`a`) as e",
"sum(`c`) OVER(PARTITION BY `a`) as f"
).explain
Current plan
== Physical Plan ==
*(5) Project [e#10L, f#11L]
+- Window [sum(c#4L) windowspecdefinition(a#2L, specifiedwindowframe(RowFrame, unboundedpreceding$(), unboundedfollowing$())) AS f#11L], [a#2L]
+- *(4) Sort [a#2L ASC NULLS FIRST], false, 0

+- *(1) Range (0, 10, step=1, splits=10)
Expected plan:
== Physical Plan ==
*(4) Project [e#924L, f#925L]
+- Window [sum(d#43L) windowspecdefinition(b#41L, a#40L, specifiedwindowframe(RowFrame, unboundedpreceding$(), unboundedfollowing$())) AS e#924L], [b#41L, a#40L]
+- *(3) Sort [b#41L ASC NULLS FIRST, a#40L ASC NULLS FIRST], false, 0
+- *(3) Project [d#43L, b#41L, a#40L, f#925L]
+- Window [sum(c#42L) windowspecdefinition(a#40L, specifiedwindowframe(RowFrame, unboundedpreceding$(), unboundedfollowing$())) AS f#925L], [a#40L]
+- *(2) Sort [a#40L ASC NULLS FIRST], false, 0
+- Exchange hashpartitioning(a#40L, 200), true, [id=#282]

+- *(1) Range (0, 10, step=1, splits=10)
Also the permutations method has a O(n!) time complexity, which is very expensive when there are many partition columns, we could try to optimize it.
### Why are the changes needed?
We could apply the rule for more cases, which could improve the execution performance by eliminate unnecessary shuffle, and by reducing the time complexity from O(n!) to O(n2), the performance for the rule itself could improve
### Does this PR introduce _any_ user-facing change?
no
### How was this patch tested?

### What changes were proposed in this pull request? This PR proposes to add `doCanonicalize` function for DataSourceV2ScanRelation. The implementation is similar to [the one in BatchScanExec](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/v2/BatchScanExec.scala#L150), as well as the [the one in LogicalRelation](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/LogicalRelation.scala#L52). ### Why are the changes needed? Query optimization rules such as MergeScalarSubqueries check if two plans are identical by [comparing their canonicalized form](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/MergeScalarSubqueries.scala#L219). For DSv2, for physical plan, the canonicalization goes down in the child hierarchy to the BatchScanExec, which [has a doCanonicalize function](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/v2/BatchScanExec.scala#L150); for logical plan, the canonicalization goes down to the DataSourceV2ScanRelation, which, however, does not have a doCanonicalize function. As a result, two logical plans who are semantically identical are not identified. Moreover, for reference, [DSv1 LogicalRelation](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/LogicalRelation.scala#L52) also has `doCanonicalize()`. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? A new unit test is added to show that `MergeScalarSubqueries` is working for DataSourceV2ScanRelation. For a query ```sql select (select max(i) from df) as max_i, (select min(i) from df) as min_i ``` Before introducing the canonicalization, the plan is ``` == Parsed Logical Plan == 'Project
