> Lower minimum-allocation-mb to sensible defaults

> Key: MAPREDUCE-4026
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4026
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2, scheduler
> Affects Versions: 2.0.0
> Reporter: Harsh J

> The CapacityScheduler's minimum-allocation-mb is set to 1024.
> The FIFO's minimum-allocation-mb meanwhile, is 128.
> I propose changing the formers' minimum to that amount as well. 1024 is way
> too much as a default, wastes "slots" on NMs - and I also do not see why CS
> has to deviate that settings from the FIFO default.
