> 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. !
