             Summary: Optimize FSPreemptionThread#identifyContainersToPreempt 
method
                 Key: YARN-9041
                 URL: https://issues.apache.org/jira/browse/YARN-9041
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Wanqiang Ji
            Assignee: Wanqiang Ji


In FSPreemptionThread#identifyContainersToPreempt method, I suggest if AM 
preemption, and locality relaxation is allowed, then the search space is 
expanded to all nodes changed to the remaining nodes. The remaining nodes are 
equal to all nodes minus the potential nodes.

Judging condition changed to:
 # rr.getRelaxLocality()
 # !ResourceRequest.isAnyLocation(rr.getResourceName())
 # bestContainers != null
 # bestContainers.numAMContainers > 0

If I understand the deviation, please criticize me. thx~
