Karthik Kambatla commented on MAPREDUCE-5652:
---------------------------------------------
+1 to the wrapper approach. We should probably go ahead and make it a util
class, and ping yarn-dev@ so other features using LevelDB are aware of this.
> NM Recovery. ShuffleHandler should handle NM restarts

> re-execution of map tasks and should be avoided.
