Siddharth Seth commented on MAPREDUCE-4582:
-------------------------------------------
Thanks for the updated patch. Needs one minor fix - removing entries from
attemptToLaunchRequestMap needs to happen after the ScheduledRequests.remove
call.
> [MAPREDUCE-3902] ScheduledRequests#remove should remove the elements from
> mapsHostMapping and mapsRackMapping
