> 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.
