The failed test cases seem unrelated to the patch(most failed reasons are 
'java.net.BindException: Address already in use'). They pass on my local

> If we submit a app and the number of running app in its corresponding leaf 
> queue has reached its max limit, the app will be put into 'nonRunnableApps'. 
> And its runnabiltiy will only be updated when removing a 
> appattempt(FairScheduler will call `updateRunnabilityOnAppRemoval` at that 
> time).
> Suppose there are only service apps running, they will not finish, so the 
> submitted app will not be scheduled even we change leaf queue's max limit. I 
> think we need update apps' runnability when reloading allocation files for 
> FairScheduler.
