             Summary: LauncherAM should cancel delegation tokens at job end.
                 Key: OOZIE-2904
                 URL: https://issues.apache.org/jira/browse/OOZIE-2904
             Project: Oozie
          Issue Type: Bug
            Reporter: Peter Cseh


 We do need to have the delegation tokens cancelled. AM itself should not be 
cancelling the tokens. It has tell the RM via 
ApplicationSubmissionContext.setCancelTokensWhenComplete and RM has to do it.

Make sure the early exit of the LauncherAM in  the case of MR action does not 
cause issues.
