[jira] [Created] (TEZ-2402) Handle DataMovementEvent before its TaskAttemptCompletedEvent

Jeff Zhang created TEZ-2402:
-------------------------------

             Summary: Handle DataMovementEvent before its TaskAttemptCompletedEvent
                 Key: TEZ-2402
                 URL: https://issues.apache.org/jira/browse/TEZ-2402
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Jeff Zhang
            Assignee: Jeff Zhang


TEZ-2325 route TASK_ATTEMPT_COMPLETED_EVENT directly to the attempt, but it would cause recovery issue. Recovery need that DataMovement event is handled before TaskAttemptCompletedEvent, otherwise DataMovement event may be lost in recovering and cause the its dependent tasks hang.

2 Ways to fix this issue.

1. Still route TaskAtttemptCompletedEvent in Vertex
2. route DataMovementEvent before TaskAttemptCompeltedEvent in TezTaskAttemptListener
