> The default value of *yarn.timeline-service.app-collector.linger-period.ms* is 1 sec
which is very low. In production cluster, we observe that most of the entity information is
not published because of 1sec linger period. 
> I would suggest to increase the default value to either 10sec or 30sec or 60 sec. As
far as I have seen, 10sec should be sufficient since node heartbeat period is 3 sec by default,
all NM gets request to stop the application.
