PS there's another instance in UnionRDD. We can make this change if we drop 2.11 support. |

Yes I am aware of that. This one is OK if we switch scala version 2.11. |

Oh I get it. This one isn't used in a ForkJoinSupport. OK it's fine. |

There was a problem hiding this comment.
Import the class rather then fully qualify it 5 times? EDIT: actually it's already imported in the java.util.concurrent._ import. Also we can make this private for tidiness.

Sorry for the noise, but I see ThreadUtils.newForkJoinPool is used in SQL and streaming, where it is fed into a ThreadPoolTaskSupport. That won't compile. |

…ver)QueryTestSuite ### What changes were proposed in this pull request? This PR adds 2 changes regarding exception handling in `SQLQueryTestSuite` and `ThriftServerQueryTestSuite` - fixes an expected output sorting issue in `ThriftServerQueryTestSuite` as if there is an exception then there is no need for sort - introduces common exception handling in those 2 suites with a new `handleExceptions` method ### Why are the changes needed? Currently `ThriftServerQueryTestSuite` passes on master, but it fails on one of my PRs (apache#23531) with this error (https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/111651/testReport/org.apache.spark.sql.hive.thriftserver/ThriftServerQueryTestSuite/sql_3/): ``` org.scalatest.exceptions.TestFailedException: Expected " [Recursion level limit 100 reached but query has not exhausted, try increasing spark.sql.cte.recursion.level.limit org.apache.spark.SparkException] ", but got " [org.apache.spark.SparkException Recursion level limit 100 reached but query has not exhausted, try increasing spark.sql.cte.recursion.level.limit] " Result did not match for query #4 WITH RECURSIVE r(level) AS ( VALUES (0) UNION ALL SELECT level + 1 FROM r ) SELECT * FROM r ``` The unexpected reversed order of expected output (error message comes first, then the exception class) is due to this line: https://github.com/apache/spark/pull/26028/files#diff-b3ea3021602a88056e52bf83d8782de8L146. It should not sort the expected output if there was an error during execution. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Existing UTs. Closes apache#26028 from peter-toth/SPARK-29359-better-exception-handling. Authored-by: Peter Toth <[email protected]> Signed-off-by: Yuming Wang <[email protected]>

### What changes were proposed in this pull request? This PR introduces sasl retry count in RetryingBlockTransferor. ### Why are the changes needed? Previously a boolean variable, saslTimeoutSeen, was used. However, the boolean variable wouldn't cover the following scenario: 1. SaslTimeoutException 2. IOException 3. SaslTimeoutException 4. IOException Even though IOException at #2 is retried (resulting in increment of retryCount), the retryCount would be cleared at step #4. Since the intention of saslTimeoutSeen is to undo the increment due to retrying SaslTimeoutException, we should keep a counter for SaslTimeoutException retries and subtract the value of this counter from retryCount. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? New test is added, courtesy of Mridul. Closes apache#39611 from tedyu/sasl-cnt.

…edExpression() ### What changes were proposed in this pull request? In `EquivalentExpressions.addExpr()`, add a guard `supportedExpression()` to make it consistent with `addExprTree()` and `getExprState()`. ### Why are the changes needed? This fixes a regression caused by apache#39010 which added the `supportedExpression()` to `addExprTree()` and `getExprState()` but not `addExpr()`. One example of a use case affected by the inconsistency is the `PhysicalAggregation` pattern in physical planning. There, it calls `addExpr()` to deduplicate the aggregate expressions, and then calls `getExprState()` to deduplicate the result expressions. Guarding inconsistently will cause the aggregate and result expressions go out of sync, eventually resulting in query execution error (or whole-stage codegen error). ### Does this PR introduce _any_ user-facing change? This fixes a regression affecting Spark 3.3.2+, where it may manifest as an error running aggregate operators with higher-order functions. Example running the SQL command: ```sql select max(transform(array(id), x -> x)), max(transform(array(id), x -> x)) from range(2) ``` example error message before the fix: ``` java.lang.IllegalStateException: Couldn't find max(transform(array(id#0L), lambdafunction(lambda x#2L, lambda x#2L, false)))#4 in [max(transform(array(id#0L), lambdafunction(lambda x#1L, lambda x#1L, false)))#3] ``` after the fix this error is gone. ### How was this patch tested? Added new test cases to `SubexpressionEliminationSuite` for the immediate issue, and to `DataFrameAggregateSuite` for an example of user-visible symptom. Closes apache#40473 from rednaxelafx/spark-42851. Authored-by: Kris Mok <[email protected]> Signed-off-by: Wenchen Fan <[email protected]>
