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.
