> 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.
