Inigo Goiri commented on YARN-3534:

It looks like there's a consensus on splitting on monitoring and reporting. If 
everybody is cool with it, I will rename this JIRA to "Collect node resource 
utilization" and just do the implementaiton of NodeResourceMonitor.

The argument of how to pass this information to the RM seems still open. Should 
I open a new JIRA for that and move the discussion about using REST, heartbeat 
etc to that one? Or should we have that discussion in one of the related JIRAs 
(e.g., YARN-3332)?
