--------------------------------
Summary: NM notify RM on running Apps in NM-RM heartbeat
Key: YARN-3445
URL: https://issues.apache.org/jira/browse/YARN-3445
Project: Hadoop YARN
Issue Type: Sub-task
Components: nodemanager, resourcemanager
Affects Versions: 2.7.0
Reporter: Junping Du
Assignee: Junping Du
Per discussion in YARN-3334, we need filter out unnecessary collectors info
from RM in heartbeat response. Our propose is to add additional field for
running apps in NM heartbeat request, 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.
