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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
