> As part of the discussion in YARN-6901 I noticed that we are recomputing a
> queue's path for every allocation. Currently getting the queue's path
> involves calling getQueuePath on the parent then building onto that string
> with the basename of the queue. In turn the parent's getQueuePath method
> does the same, so we end up spending time recomputing a string that will
> never change until a reconfiguration.
> Ideally the queue path should be computed once during queue initialization
> rather than on-demand.
