Jeff Zhang updated TEZ-1644:
----------------------------
    Description: 
Vertex/Task/TaskAttempt can move from SUCCEEDED to FAILED/KILLED, that means it would finish
multiple times. And this will cause some potential issue.
* DAGEventCounterUpdate will been send multiple times, cause wrong Counter
* successfulAttempt in Task should been set to null if FAILED/KILLED followed by SUCCEEDED

more investigation need to do for other impact.
