> We want to allow certain queues to use larger container sizes while limiting 
> other queues to smaller container sizes.  Setting it per queue will help 
> prevent abuse, help limit the impact of reservations, and allow changes in 
> the maximum container size to be rolled out more easily.
> One reason this is needed is more application types are becoming available on 
> yarn and certain applications require more memory to run efficiently. While 
> we want to allow for that we don't want other applications to abuse that and 
> start requesting bigger containers then what they really need.  
> Note that we could have this based on application type, but that might not be 
> totally accurate either since for example you might want to allow certain 
> users on MapReduce to use larger containers, while limiting other users of 
> MapReduce to smaller containers.
