Jason Lowe commented on MAPREDUCE-5652:
---------------------------------------
As for the utility class, where would it go? I'm assuming yarn-server-common,
otherwise we end up with clients picking it up. We'd have to add the leveldb
dependency there which is unfortunate for those servers that don't really need
it (i.e.: resourcemanager, webproxy).

> 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.
