             Summary: CapacityScheduler should respect maximum node resource when per-queue maximum-allocation is being used.
                 Key: YARN-8858
                 URL: https://issues.apache.org/jira/browse/YARN-8858
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Sumana Sathish
            Assignee: Wangda Tan


This issue happens after YARN-8720.

Before that, AMS uses scheduler.getMaximumAllocation to do the normalization. After that, AMS uses LeafQueue.getMaximumAllocation. The scheduler one uses nodeTracker.getMaximumAllocation, but the LeafQueue.getMaximum doesn't. 

We should use the scheduler.getMaximumAllocation to cap the per-queue's maximum-allocation every time.
