Daniel Templeton commented on YARN-6301:
----------------------------------------

Thanks, [~Tao Jie].  You're on the right track, but I'd like to be a little 
more explicit.  A queue with weight 0 will not receive resources as long as 
there is demand from any other queue.  A weight-0 queue is often called an "ad 
hoc queue."

> Fair scheduler docs should explain the meaning of setting a queue's weight to 
> zero
