-------------------------------
Summary: Handle DataMovementEvent before its
TaskAttemptCompletedEvent
Key: TEZ-2404
URL: https://issues.apache.org/jira/browse/TEZ-2404
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
