Mridul Muralidharan resolved SPARK-47910. ----------------------------------------- Fix Version/s: 3.5.2 4.0.0 Resolution: Fixed Issue resolved by pull request 46131 [https://github.com/apache/spark/pull/46131] > Memory leak when interrupting shuffle write using zstd compression > ------------------------------------------------------------------ > > Key: SPARK-47910 > URL: https://issues.apache.org/jira/browse/SPARK-47910 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 3.2.0, 3.3.0, 3.4.0, 3.5.0 > Reporter: JacobZheng > Assignee: JacobZheng > Priority: Major > Labels: pull-request-available > Fix For: 3.5.2, 4.0.0 > > > When spark.sql.execution.interruptOnCancel=true and > spark.io.compression.codec=zstd, a memory leak was found when tasks were > cancelled at specific times. The reason for this is that cancelling a task > interrupts the shuffle write, which then calls > org.apache.spark.storage.DiskBlockObjectWriter#closeResources. this process > then only closes the ManualCloseOutputStream, which is wrapped with this > ZstdInputStreamNoFinalizer will not be closed. Moreover, > ZstdInputStreamNoFinalizer doesn't implement Finalizer so it won't be > reclaimed by GC automatically. > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
