------------------------------
Assignee: Yufei Gu
> Fair Scheduler :ability to optionally configure minResources and maxResources
> in terms of percentage
> ----------------------------------------------------------------------------------------------------
>
> Key: YARN-2162
> URL: https://issues.apache.org/jira/browse/YARN-2162
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: scheduler
> Reporter: Ashwin Shankar
> Assignee: Yufei Gu
> Labels: scheduler
>
> minResources and maxResources in fair scheduler configs are expressed in
> terms of absolute numbers X mb, Y vcores.
> As a result, when we expand or shrink our hadoop cluster, we need to
> recalculate and change minResources/maxResources accordingly, which is pretty
> inconvenient.
> We can circumvent this problem if we can optionally configure these
> properties in terms of percentage of cluster capacity.
