Description

None of the current yarn.scheduler.fifo.minimum/maximum-allocation-mb and yarn.scheduler.capacity.minimum/maximum-allocation-mb are documented anywhere. Without knowledge of these params, one can't change the default allocations. And the default allocations are pretty high btw (MAPREDUCE-4026).

We should document these in the Cluster Setup page at least.
