Junping Du updated YARN-3445:
-----------------------------
Description: 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. (was: Per discussion in YARN-3334, we need filter out

add additional field for running apps in NM heartbeat request, so RM only send
