----------------------------------------

             Summary: CLONE - CapacityScheduler incorrectly utilizes extra-resources of queue
for high-memory jobs
                 Key: MAPREDUCE-5290
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5290
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: capacity-sched
    Affects Versions: 1.0.0
            Reporter: Sergey Tryuber
            Assignee: Sergey Tryuber
             Fix For: 1.2.1


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.
