Shixiong Zhu resolved SPARK-25181. ---------------------------------- Resolution: Fixed Assignee: Mukul Murthy Fix Version/s: 2.4.0 > Block Manager master and slave thread pools are unbounded > --------------------------------------------------------- > > Key: SPARK-25181 > URL: https://issues.apache.org/jira/browse/SPARK-25181 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 2.3.0 > Reporter: Mukul Murthy > Assignee: Mukul Murthy > Priority: Major > Fix For: 2.4.0 > > > Currently, BlockManagerMasterEndpoint and BlockManagerSlaveEndpoint both have > thread pools with unbounded numbers of threads. In certain cases, this can > lead to driver OOM errors. We should add an upper bound on the number of > threads in these thread pools; this should not break any existing behavior > because they still have queues of size Integer.MAX_VALUE. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
