["Weiwei Yang (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-8987?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Weiwei Yang updated YARN-8987:
------------------------------
    Description: 
I setup a single node cluster, then trying to add node-attributes with CLI,

first I tried:
{code:java}
./bin/yarn nodeattributes -add localhost:hostname(STRING)=localhost
{code}
this command returns exit code 0, however the node-attribute was not added.

Then I tried to replace "localhost" with the host ID, and it worked.

We need to ensure the command fails with proper error message when adding was not succeed.
