Jason Lowe commented on MAPREDUCE-5652:
---------------------------------------
No branch yet, just an ugly internal prototype that needs a bit of cleanup
before publishing. I meant to post either a branch or sets of draft patches to
the JIRAs last month but got swamped with other stuff. I'll try to get some
things posted i the next week or so.
> ShuffleHandler should handle NM restarts
> ----------------------------------------
>
> Key: MAPREDUCE-5652
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5652
> 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.
