------------------------------
Resolution: Duplicate
> 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
