Sunil G commented on YARN-3630:
-------------------------------
bq.Are we considering automatically slowing down the NM heartbeats as well?
+1. It will be wise to slowdown the heartbeats from NM which shares a less
load. However there should be a limit or range to which it can be slowed down
even in lighter load. Else i feel more starvation can happen for applications.
> YARN should suggest a heartbeat interval for applications

> It seems currently applications - for example Spark - are not adaptive to RM
> regarding heartbeat intervals. RM should be able to suggest a desired
> heartbeat interval to applications.
