             Summary: RM fails to renew token when Oozie launcher leaves before 
sub-job finishes
                 Key: YARN-3439
                 URL: https://issues.apache.org/jira/browse/YARN-3439
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.7.0
            Reporter: Jason Lowe
            Assignee: Daryn Sharp
            Priority: Blocker


When the Oozie launcher runs a standard MapReduce job (not Pig) it doesn't 
linger waiting for the sub-job to finish.  At that point the RM stops renewing 
delegation tokens for the launcher job which wreaks havoc on the sub-job if the 
sub-job runs long enough for the tokens to expire.
