Arun C Murthy commented on MAPREDUCE-2788:
------------------------------------------
Ahmed - another way would be to ensure there are no requests which need
memory=0 - this check can be enforced in CS.normalizeRequests. Do you want to
take a crack at that? Also, please mark this as PA when done - that way I (or
other committers) can pick it up on my PA filter. Thanks.
> LeafQueue.assignContainer() can cause a crash if
> request.getCapability().getMemory() == 0
