Summary: FairSchduler AllocationConfiguration doesn't treat
hierarchical queues settings
Project: Hadoop YARN
Issue Type: Bug
Reporter: Andrey Stepachev
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.
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 a have made an attempt
looks like it lead to some inconstancy and I think that it is not necessary
