Summary: 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
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.
