> I'm trying to using the node label with latest hadoop (3.1.0-SNAPSHOT). But when I add a new node label and append a nodemanager to it, sometimes it may cause a display error.
> !DisplayError.png|width=573,height=188!
> Then I found *when there is no queues can access to the label*, this error will happen.
> After checking the log, I find some NPE errors.
