Apache Spark commented on SPARK-11293: -------------------------------------- User 'lianhuiwang' has created a pull request for this issue: https://github.com/apache/spark/pull/13027 > Spillable collections leak shuffle memory > ----------------------------------------- > > Key: SPARK-11293 > URL: https://issues.apache.org/jira/browse/SPARK-11293 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.3.1, 1.4.1, 1.5.1, 1.6.0, 1.6.1 > Reporter: Josh Rosen > Assignee: Josh Rosen > Priority: Critical > > I discovered multiple leaks of shuffle memory while working on my memory > manager consolidation patch, which added the ability to do strict memory leak > detection for the bookkeeping that used to be performed by the > ShuffleMemoryManager. This uncovered a handful of places where tasks can > acquire execution/shuffle memory but never release it, starving themselves of > memory. > Problems that I found: > * {{ExternalSorter.stop()}} should release the sorter's shuffle/execution > memory. > * BlockStoreShuffleReader should call {{ExternalSorter.stop()}} using a > {{CompletionIterator}}. > * {{ExternalAppendOnlyMap}} exposes no equivalent of {{stop()}} for freeing > its resources. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
