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.
