resource allocation respect queue's max capacity
URL: https://github.com/apache/hadoop/pull/7753
> Non-exclusive resource allocation respect queue's max capacity
> --------------------------------------------------------------
>
> Key: YARN-11828
> URL: https://issues.apache.org/jira/browse/YARN-11828
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacityscheduler
> Reporter: liu bin
> Priority: Major
> Labels: pull-request-available
>
> Now when doing non-exclusive resource allocation, queue's max capacity on the
> partition will be considered to be 100%. In an ideal situation, preemption
> policy will reclaim resource back when partitoned-resource-request comes back.
> But our cluster has not enabled preemption, so a queue may use all resource
> on the partition and block the partitoned-resource-request of other queues.
> In this situation, we hope queue's max capacity will be respect when doing
> non-exclusive resource allocation.
