Jason Lowe commented on YARN-7018:
----------------------------------
Thanks for updating the patch!
Overall looks OK for a POC. Would be good to hear [~leftnoteasy]'s thoughts on
the latest revision.
Some minor points:
Since the plugin has init and stop, wondering if we should just have the plugin
extend Service so we have the full init/start/stop lifecycle.

> This JIRA tracks an interface for plugging in new behavior to node heartbeat
> processing. Adding a formal interface for additional node heartbeat
> processing would allow admins to configure new functionality that is
> scheduler-independent without needing to replace the entire scheduler. For
> example, both YARN-5202 and YARN-5215 had approaches where node heartbeat
> processing was extended to implement new functionality that was essentially
> scheduler-independent and could be implemented as a plugin with this
> interface.
