Daniel Templeton commented on YARN-4329:
----------------------------------------

Latest patch looks great.  A couple of tiny quibbles:

* These lines {code}     boolean nowRunnable = 
maxRunningEnforcer.canAppBeRunnable(newQueue,
        attempt);{code} can probably be combined into one.
* Your messages {{"User runnable application number has reached its maximum 
limit."}} and {{"Queue runnable application number has reached its maximum 
limit."}} would be clearer as {{"The user has reached the maximum limit of 
runnable applications."}} and {{"The <queue_name> queue has reached the maximum 
limit of runnable applications."}}.
* In some of your javadocs you put a newline between the description and 
params, and in some you don't.  Better to be consistent.  I prefer it with the 
newline.
