Mike Roark commented on MAPREDUCE-3859:
---------------------------------------
Good call, I'd forgotten to readjust
mapred.capacity-scheduler.default-user-limit-factor after I added some
additional queues, so it was skewing the numbers.
After fixing that I got exactly what I expected.
> CapacityScheduler incorrectly utilizes extra-resources of queue for
> high-memory jobs
