Harsh J updated MAPREDUCE-4027:
-------------------------------
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.
