-----------------------------------
Summary: Some NPE errors caused a display errors when setting node
labels
Key: YARN-7925
URL: https://issues.apache.org/jira/browse/YARN-7925
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 3.1.0
Reporter: Jinjiang Ling
Assignee: Jinjiang Ling
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.

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.
