Carlo Curino commented on YARN-1707:
------------------------------------

Agreed on all of the above.

I think for moving application across queue is not a ReservationSystem specific 
change. I would suggest to check it will not violate restrictions in target 
queue before moving it.

This makes sense, we should compile a list of invariant to check for (I have a 
few in mind, but feedback is likely useful).

Thanks,
Carlo

> 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.
