> Currently, both of fair/capacity scheduler support queue mapping, which makes 
> scheduler can change queue of an application after submitted to scheduler.
> One issue of doing this in specific scheduler is: If the queue after mapping 
> has different maximum_allocation/default-node-label-expression of the 
> original queue, {{validateAndCreateResourceRequest}} in RMAppManager checks 
> the wrong queue.
> I propose to make the queue mapping as a common interface of scheduler, and 
> RMAppManager set the queue after mapping before doing validations.
