Arun C Murthy updated MAPREDUCE-2788:
-------------------------------------
Status: Open (was: Patch Available)
Ahmed - not sure when this happened, but looks like CS.allocate already
normalizes the incoming request.
Thus, we might only need to fix FifoScheduler.normalizeRequest?
We should pull out normalizeRequest to SchedulerUtils and use it from both
places?
> LeafQueue.assignContainer() can cause a crash if
> request.getCapability().getMemory() == 0
