Junping Du commented on YARN-3445:
----------------------------------

Thanks [~vinodkv] for review and comments, I just deliver a quick demo patch in 
YARN-3586 (target for YARN-2928) to demonstrate how patch here helps to improve 
RM get back NM with limited number of collector addresses. Can you help to take 
a look?
BTW, YARN-3212 for gracefully decommission need this patch too, so our target 
branch here is still for trunk/branch-2.

> Per discussion in YARN-3334, we need filter out unnecessary collectors info 
> from RM in heartbeat response. Our propose is to add cache for runningApps in 
> RMNode, so RM only send collectors for local running apps back. This is also 
> needed in YARN-914 (graceful decommission) that if no running apps in NM 
> which is in decommissioning stage, it will get decommissioned immediately.
