Subramaniam Venkatraman Krishnan updated YARN-2378:
---------------------------------------------------

    Description: As discussed with [~leftnoteasy] and [~jianhe], we are 
breaking up YARN-1707 to smaller patches for manageability. This JIRA will 
address adding support for moving apps between queues in Capacity Scheduler.  
(was: 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. )
