> Currently Capacity Scheduler doesn't support auto creation of queues when
> doing queue mapping. We saw more and more use cases which has complex queue
> mapping policies configured to handle application to queues mapping.
> The most common use case of CapacityScheduler queue mapping is to create one
> queue for each user/group. However update {{capacity-scheduler.xml}} and
> {{RMAdmin:refreshQueues}} needs to be done when new user/group onboard. One
> of the option to solve the problem is automatically create queues when new
> user/group arrives.
