CapacityScheduler incorrectly utilizes extra-resources of queue for high-memory jobs
------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3859
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3859
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/capacity-sched
         Environment: CDH3u1
            Reporter: Sergey Tryuber


Imagine, we have a queue A with capacity 10 slots and 20 as extra-capacity, jobs which use
3 map slots will never consume more than 9 slots, regardless how many free slots on a cluster.
