Ismael Juma commented on KAFKA-4431: ------------------------------------ I cherry-picked this to the 0.10.1 branch as it's a trivial fix and has user visible impact. > HeartbeatThread should be a daemon thread > ----------------------------------------- > > Key: KAFKA-4431 > URL: https://issues.apache.org/jira/browse/KAFKA-4431 > Project: Kafka > Issue Type: Bug > Components: clients > Affects Versions: 0.10.1.0 > Reporter: David Judd > Assignee: Rajini Sivaram > Fix For: 0.10.1.1, 0.10.2.0 > > > We're seeing an issue where an exception inside the main processing loop of a > consumer doesn't cause the JVM to exit, as expected (and, in our case, > desired). From the thread dump, it appears that what's blocking exit is the > "kafka-coordinator-heartbeat-thread", which is not currently a daemon thread. > Per the mailing list, it sounds like this is a bug. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
