-------------------------------
Summary: potential NPE in checkRemoveLabelsFromNode of CommonNodeLabelsManager
Key: YARN-2753
URL: https://issues.apache.org/jira/browse/YARN-2753
Project: Hadoop YARN
Issue Type: Bug
Reporter: zhihai xu
Assignee: zhihai xu
potential NPE(NullPointerException) in checkRemoveLabelsFromNode of CommonNodeLabelsManager.
It because when a Node is created, Node.labels can be null.
In this case, nm.labels; may be null.
So we need check originalLabels not null before use it(originalLabels.containsAll).
