> AllocationConfiguration doesn't fully qualify queue names with respect to 
> 'root.' prefix. Such behaviour leads to situation where settings for nested 
> queue doesn't take effect. 
> Consider following config (working example in broken-hier-queues.diff 
> attached) sub queue settings were not applied by method 
> queueConf.getMaxResources.
> {code:xml}
> <queue name="queueA">
> <maxResources>2048mb,10vcores</maxResources>
> <queue name="queueB">
> <maxResources>512mb,1vcores</maxResources>
> </queue>
> </queue>
> {code}
> I made patch, which unifies QueueName operations (remove those indexOf copy 
> pastes) and apply some of settings in hierarchical manner  (say preemption 
> timeout can be used from parent queue instead of global default).
> Also it is interesting to introduce type safe object QueueName and replace 
> String in interfaces, and I have made an attempt 
> (https://github.com/octo47/hadoop-common/tree/feature/octo/fs-queue-name), 
> but looks like it lead to some inconsitancy and I think that it is not 
> necessary right now).
