Summary: Automatic and Asynchronous Decommissioning Nodes Status
Tracking
Key: YARN-4676
URL: https://issues.apache.org/jira/browse/YARN-4676
Project: Hadoop YARN
Issue Type: Sub-task
Components: resourcemanager
Affects Versions: 2.8.0
Reporter: Daniel Zhi
Fix For: 2.8.0
DecommissioningNodeWatcher inside ResourceTrackingService tracks
DECOMMISSIONING nodes status automatically and asynchronously after
client/admin made the graceful decommission request. It tracks DECOMMISSIONING
nodes status to decide when, after all running containers on the node have
completed, will be transitioned into DECOMMISSIONED state. NodesListManager
detect and handle include and exclude list changes to kick out decommission or
recommission as necessary.
