----------------------------------
Any updates for this jira? Why not add yarn.scheduler.maximum-allocation-vcores
to each queue?
> Capacity Scheduler: add a maximum-allocation-mb setting per queue

> Key: YARN-1582
> URL: https://issues.apache.org/jira/browse/YARN-1582
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacityscheduler
> Affects Versions: 3.0.0, 0.23.10, 2.2.0
> Reporter: Thomas Graves

> We want to allow certain queues to use larger container sizes while limiting
> other queues to smaller container sizes. Setting it per queue will help
> prevent abuse, help limit the impact of reservations, and allow changes in
> the maximum container size to be rolled out more easily.
> One reason this is needed is more application types are becoming available on
> yarn and certain applications require more memory to run efficiently. While
> we want to allow for that we don't want other applications to abuse that and
> start requesting bigger containers then what they really need.
> Note that we could have this based on application type, but that might not be
> totally accurate either since for example you might want to allow certain
> users on MapReduce to use larger containers, while limiting other users of
> MapReduce to smaller containers.
