> In Fair Scheduler, we want to be able to create user queues under any parent
> queue in the hierarchy. For eg. Say user1 submits a job to a parent queue
> called root.allUserQueues, we want be able to create a new queue called
> root.allUserQueues.user1 and run user1's job in it.Any further jobs submitted
> by this user to root.allUserQueues will be run in this newly created
> root.allUserQueues.user1.
> This is very similar to the 'user-as-default' feature in Fair Scheduler which
> creates user queues under root queue. But we want the ability to create user
> queues under ANY parent queue.
> Why do we want this ?
> 1. Preemption : these dynamically created user queues can preempt each other
> if its fair share is not met. So there is fairness among users.
> User queues can also preempt other non-user leaf queue as well if below fair
> share.
> 2. Allocation to user queues : we want all the user queries(adhoc) to consume
> only a fraction of resources in the shared cluster. By creating this
> feature,we could do that by giving a fair share to the parent user queue
> which is then redistributed to all the dynamically created user queues.
