Karthik Kambatla commented on MAPREDUCE-5652:
---------------------------------------------
Thanks for the update, [~jlowe]. Glad to know this is being handled as part of
YARN-1336. Looks like it is better to just wait for YARN-1336 to be done, and
address any remaining items here. Please feel free to take this over too.
Curious - is there a branch for the YARN-1336 changes I can take an early peek
at?
> 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.
