             Summary: userlimit isn't playing well with DRF calculator
                 Key: YARN-3388
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
    Affects Versions: 2.6.0
            Reporter: Nathan Roberts
            Assignee: Nathan Roberts

When there are multiple active users in a queue, it should be possible for 
those users to make use of capacity up-to max_capacity (or close). The 
resources should be fairly distributed among the active users in the queue. 
This works pretty well when there is a single resource being scheduled.   
However, when there are multiple resources the situation gets more complex and 
the current algorithm tends to get stuck at Capacity. 

Example illustrated in subsequent comment.
