Naganarasimha G R commented on YARN-3034:

Also [~zjshen], earlier thought process  to expose RMTimelineCollector to RM 
and it's context, was to gradually replace SystemMetricsPublisher with 
RMTimelineCollector, as i felt once we deprecate & completely remove ATSV1, we 
might not require much of the functionality of SystemMetricsPublisher and it 
will be just delegating the calls to RMTimelineCollector. your thoughts ?
