[jira] [Updated] (MAPREDUCE-4027) Document the
minimum-allocation-mb configurations
[ https://issues.apache.org/jira/browse/MAPREDUCE-4027?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Joseph Evans updated MAPREDUCE-4027:
-------------------------------------------
Target Version/s: 2.0.0, trunk (was: 0.23.3, 0.24.0)
> Document the minimum-allocation-mb configurations
> -------------------------------------------------
>
> Key: MAPREDUCE-4027
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4027
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 0.23.3
> Reporter: Harsh J
> Assignee: Harsh J
> Priority: Minor
>
> 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.
