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

    [ https://issues.apache.org/jira/browse/YARN-2351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14216465#comment-14216465 ] 

Rohith commented on YARN-2351:
------------------------------

hdfs has command like {{hdfs -namenodes}} to determine cluster NameNodes. Similarly, if yarn supports command to get yarn cluster detail.like {{yarn getConf -resourcemanager}} and other commands will be good.

> To more easily understand the expected behavior of a yarn component, it is good have the command line to be able to print the configurations in use for RM, NM and timeline server daemons, as what we can do now via the web interfaces:
> {code}
> http://<RM|NM|Timeline host>:<port>/conf
> {code}
> The command line could be something like:
> {code}
> yarn conf resourcemanager|nodemanager|timelineserver [host]
> {code}
