Ahmed Radwan updated MAPREDUCE-2788:
------------------------------------
Attachment: MAPREDUCE-2788_rev2.patch
Thanks Arun, I have updated the patch accordingly. Using CS.normalizeRequest,
the request's memory is now set to minMemory if it is zero (avoiding the divide
by zero). The revised patch is based on the recent version (after merge to
trunk).
> LeafQueue.assignContainer() can cause a crash if
> request.getCapability().getMemory() == 0
