Mukul Murthy created SPARK-25182: ------------------------------------ Summary: Block Manager master and slave thread pools are unbounded Key: SPARK-25182 URL: https://issues.apache.org/jira/browse/SPARK-25182 Project: Spark Issue Type: Bug Components: Spark Core Affects Versions: 2.3.0 Reporter: Mukul Murthy
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
