-----------------------------
Summary: Should check if node exists when replace nodelabels
Key: YARN-4855
URL: https://issues.apache.org/jira/browse/YARN-4855
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 2.6.0
Reporter: Tao Jie
Priority: Minor
Today when we add nodelabels to nodes, it would succeed even if nodes are not
existing NodeManger in cluster without any message.
It could be like this:
When we use *yarn rmadmin -replaceLabelsOnNode "node1=label1"*, it would be
denied if node does not exist.
When we use *yarn rmadmin -replaceLabelsOnNode -force "node1=label1"* would add
nodelabels no matter whether node exists
