Sean Owen commented on SPARK-10911: ----------------------------------- Agree, but what about the correctness problem of killing user threads immediately? > Executors should System.exit on clean shutdown > ---------------------------------------------- > > Key: SPARK-10911 > URL: https://issues.apache.org/jira/browse/SPARK-10911 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.5.1 > Reporter: Thomas Graves > > Executors should call System.exit on clean shutdown to make sure all user > threads exit and jvm shuts down. > We ran into a case where an Executor was left around for days trying to > shutdown because the user code was using a non-daemon thread pool and one of > those threads wasn't exiting. We should force the jvm to go away with > System.exit. -- 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
