Chang Li updated MAPREDUCE-5003:
--------------------------------
Attachment: MAPREDUCE-5003.1.patch
the AM hanging issue mentioned in MAPREDUCE-4992 no longer exists in current
recover implementation. Moreover, current recovery implementation for task
attempts will recover incomplete task attempts to killed state. So we no longer
need to remove those incomplete task attempts for recovery.
> AM recovery should recreate records for attempts that were incomplete

> As discussed in MAPREDUCE-4992, it would be nice if the AM recovered task
> attempt entries for *all* task attempts launched by the prior app attempt
> even if those task attempts did not complete. The attempts would have to be
> marked as killed or something similar to indicate it is no longer running.
> Having records for the task attempts enables the user to see what nodes were
> associated with the attempts and potentially access their logs.
