Andrew Or commented on SPARK-3632: ---------------------------------- Ok, sounds good. > ConnectionManager can run out of receive threads with authentication on > ----------------------------------------------------------------------- > > Key: SPARK-3632 > URL: https://issues.apache.org/jira/browse/SPARK-3632 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.1.0 > Reporter: Thomas Graves > Assignee: Thomas Graves > Priority: Critical > Fix For: 1.2.0 > > > If you turn authentication on and you are using a lot of executors. There is > a chance that all the of the threads in the handleMessageExecutor could be > waiting to send a message because they are blocked waiting on authentication > to happen.
