Steve Loughran commented on YARN-3630:
--------------------------------------

OK, adaptive does make sense: the RM can instruct AMs to back off as it 
experiences load. Telling them to speed up again will take more time (since 
they are backed off), but that probably matters less

> 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.
