Date Thu, 22 Feb 2018 18:14:00 GMT
Yesha Vora created YARN-7961:
--------------------------------

             Summary: Improve status response when yarn application is destroyed
                 Key: YARN-7961
                 URL: https://issues.apache.org/jira/browse/YARN-7961
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn-native-services
    Affects Versions: 3.1.0
            Reporter: Yesha Vora


Yarn should provide some way to figure out if yarn service is destroyed.

If yarn service application is stopped, "yarn app -status <appname>" shows that service
is Stopped. 

After destroying yarn service, "yarn app -status <appname>" returns 404
{code}
[hdpuser@cn005 sleeper]$ yarn app -status yesha-sleeper
