Harsh J commented on MAPREDUCE-4027:
------------------------------------
The org.apache.hadoop.yarn.server.resourcemanager.TestFifoScheduler failure
will be fixed by MAPREDUCE-4026. It resulted for this cause yarn-default.xml
now carries new defaults.
The other failure is unrelated.
> Document the minimum-allocation-mb configurations

> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 0.23.3

>
> None of the current yarn.scheduler.fifo.minimum-allocation-mb and
> yarn.scheduler.capacity.minimum-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.
