]

Luke Lu updated MAPREDUCE-1233:
-------------------------------

    Attachment: mr-1233-y20s-v1.patch

Patch for y20.200 branch. Trunk doesn't seem to need the patch due to MAPREDUCE-1152, where
killed tasks don't cause waiting tasks to be incremented.

> Waiting Maps/Reduces are incorrect in Jobtracker metrics when a job fails. when a map/reduce
fails(during job failure), waiting maps/reduce got incremented and doesn't get decremented
even after job cleanup.
