Jeff Zhang commented on TEZ-2581:
---------------------------------
This is the task level commit, not vertex/dag level commit. I check the
previous recovery code, the behavior is not changed. And I think if the task
level commit can not be recovered, it should be fine to reschedule a new task
attempt to rerun it.
