[jira] [Created] (TEZ-2576) It is not necessary to send NodeFailureEvent to task attempt of completed DAG

Jeff Zhang created TEZ-2576:
-------------------------------

             Summary: It is not necessary to send NodeFailureEvent to task attempt of completed DAG
                 Key: TEZ-2576
                 URL: https://issues.apache.org/jira/browse/TEZ-2576
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Jeff Zhang


When node fails, it would send NodeFailureEvent to all the task attempts on this node. It is not necessary to send this to the task attempts that belong to the completed dags. 
{code}
 for (TezTaskAttemptID taId : container.failedAssignments) {
        container.sendNodeFailureToTA(taId, errorMessage, TaskAttemptTerminationCause.NODE_FAILED);
      }
      for (TezTaskAttemptID taId : container.completedAttempts) {
        container.sendNodeFailureToTA(taId, errorMessage, TaskAttemptTerminationCause.NODE_FAILED);
      }
{code}
