             Summary: Fair Scheduler: Display demand resource for queues on the 
scheduler page
                 Key: YARN-4995
                 URL: https://issues.apache.org/jira/browse/YARN-4995
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: xupeng
            Priority: Minor


For now there is no demand resource information for queues on the scheduler 
page. 

Just using used resource information, it is hard for us to judge whether the 
queue is needy (demand > used , but cluster has no available resource). And 
without demand resource information, modifying min/max resource for queue is 
not accurate.
