Vinod Kumar Vavilapalli commented on MAPREDUCE-5652:
----------------------------------------------------
bq. I've largely implemented this as part of the prototype for YARN-1336.
Can this be closed as duplicate then? Or make it a sub-task if there isn't a
corresponding child under YARN-1336.
> ShuffleHandler should handle NM restarts

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.2.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Labels: shuffle
>
> ShuffleHandler should work across NM restarts and not require re-running
> map-tasks. On NM restart, the map outputs are cleaned up requiring
> re-execution of map tasks and should be avoided.
