             Summary: LLAP external client not properly handling KILLED 
notification that occurs when a fragment is rejected
                 Key: HIVE-17281
                 URL: https://issues.apache.org/jira/browse/HIVE-17281
             Project: Hive
          Issue Type: Bug
          Components: llap
            Reporter: Jason Dere
            Assignee: Jason Dere

When LLAP fragment submission is rejected, the external client receives both 
REJECTED and KILLED notifications for the fragment. The KILLED notification is 
being treated as an error, which prevents the retry logic from resubmitting the 
fragment. This needs to be fixed in the client logic.
