Subject [jira] [Resolved] (YARN-7036) [ATSv2] : NPE for recovered finished applications in NM during upgrade
Date Mon, 21 Aug 2017 06:54:02 GMT

     [ https://issues.apache.org/jira/browse/YARN-7036?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rohith Sharma K S resolved YARN-7036.
-------------------------------------
    Resolution: Invalid

This issue happens because of TimelineClient fail to start when we configure ssl-client.xml.
It is mandatory that if we configure ssl-client.xml values i.e the jks file must be present.

It is basically cluster set up issue which was causing this issue. Because of this subsequent
entity publishing also were failing. 

Closing the issue as invalid.

> It is seen that NPE is logged in NM logs when finished applications are recovered during
upgrade. But I do not see any impact for functionality of NM.
