Subject [jira] [Created] (YARN-5197) RM leaks containers if running container disappears from node update
Date Thu, 02 Jun 2016 21:47:59 GMT
Jason Lowe created YARN-5197:
--------------------------------

             Summary: RM leaks containers if running container disappears from node update
                 Key: YARN-5197
                 URL: https://issues.apache.org/jira/browse/YARN-5197
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.6.4, 2.7.2
            Reporter: Jason Lowe
            Assignee: Jason Lowe


Once a node reports a container running in a status update, the corresponding RMNodeImpl will
track the container in its launchedContainers map.  If the node somehow misses sending the
completed container status to the RM and the container simply disappears from subsequent heartbeats,
the container will leak in launchedContainers forever and the container completion event will
not be sent to the scheduler.
