Subject [jira] [Commented] (YARN-4441) Kill application request from the webservice(ui) is showing success even for the finished applications
Date Mon, 14 Dec 2015 10:12:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15055747#comment-15055747
] 

Varun Vasudev commented on YARN-4441:
-------------------------------------

That's a performance optimization for the RPC client - it avoids a RPC round trip. There's
nothing stopping you from writing a YARN client without that check. The equivalent to the
CLI code you posted would be to grey out the button on the web UI if the application is finished(which
is a patch I'd be ok with).
