> The CapacityScheduler is a rather static at the moment, and refreshqueue provides a rather heavy-handed way to reconfigure it. Moving towards long-running services (tracked in YARN-896) and to enable more advanced admission control and resource parcelling we need to make the CapacityScheduler more dynamic. This is instrumental to the umbrella jira YARN-1051.
> Concretely this require the following changes:
> * create queues dynamically
> * destroy queues dynamically
> * dynamically change queue parameters (e.g., capacity)
> * modify refreshqueue validation to enforce sum(child.getCapacity())<= 100% instead of ==100%
> We limit this to LeafQueues.
