Naganarasimha G R commented on YARN-4855: ----------------------------------------- Thanks [~Tao Jie], for sharing the alternate option but would like to know the background as to why this is required ? If any strong usecase then can think of supporting it ! > 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
