Vinod Kumar Vavilapalli commented on YARN-3630:

NodeManagers already get a target heartbeat interval via responses. We haven't 
seen a real-life need yet for adaptive tuning, so we haven't done that. The 
same should be done here, for now, we should just send the target interval 
across and tune it later.

>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: resourcemanager, scheduler
>    Affects Versions: 2.7.0
>            Reporter: Zoltán Zvara
>            Assignee: Xianyin Xin
>            Priority: Minor
> 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.
