[jira] [Created] (YARN-4000) RM crashes with NPE if leaf queue becomes parent queue during restart

Jason Lowe created YARN-4000:
--------------------------------

             Summary: RM crashes with NPE if leaf queue becomes parent queue during restart
                 Key: YARN-4000
                 URL: https://issues.apache.org/jira/browse/YARN-4000
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler, resourcemanager
    Affects Versions: 2.6.0
            Reporter: Jason Lowe


This is a similar situation to YARN-2308.  If an application is active in queue A and then the RM restarts with a changed capacity scheduler configuration where queue A becomes a parent queue to other subqueues then the RM will crash with a NullPointerException.
