------------------------------------------
You can't really do much in jvm with 128M heap. Maybe 512M ...
> 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: 0.23.3
> Reporter: Harsh J
> Assignee: 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.
