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

             Summary: Adding support for move all applications from a source queue to destination
queue
                 Key: YARN-2385
                 URL: https://issues.apache.org/jira/browse/YARN-2385
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: capacityscheduler
            Reporter: Subramaniam Venkatraman Krishnan
            Assignee: Carlo Curino


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.
