> Handle the user name correctly when user name is used as default queue name 
> in fair scheduler.
> It will be better to remove the trailing and leading whitespace of the user 
> name when we use user name as default queue name, otherwise it will be 
> rejected by InvalidQueueNameException from QueueManager. I think it is 
> reasonable to make this change, because we already did special handling for 
> '.' in user name.
