Sandy Ryza commented on YARN-461:
---------------------------------
My thinking was that a queue name of "" is most likely to come up when a user
means not to specify any queue (as it was when I got hit by this). Are you
saying "" should be a valid queue name? To me it seems like a lot of confusing
situations could arise if a user configures this accidentally.

> When an app is submitted with "" for the name or queue, the RMAppManager
> passes it on like it does with any other string.
> Instead it should probably use the default name and queue, as it does when it
> encounters a null name or queue.
