Rohith Sharma K S updated YARN-7835:
------------------------------------
Description:
It is observed race condition that if master container is killed for some
reason and launched on same node then NMTimelinePublisher doesn't add
timelineClient. But once completed container for 1st attempt has come then
NMTimelinePublisher removes the timelineClient.
It causes all subsequent event publishing from different client fails to
publish with exception Application is not found. !
