tangshangwen commented on YARN-5051:
------------------------------------
i think we should put the decommission node in InactiveRMNodes when it is
registered
{code:title=ResourceTrackerService.java|borderStyle=solid}
RMNode rmNode = new RMNodeImpl(nodeId, rmContext, host, cmPort, httpPort,
resolve(host), capability, nodeManagerVersion);
// Check if this node is a 'valid' node
if (!this.nodesListManager.isValidNode(host)) {
String message =
"Disallowed NodeManager from " + host
+ ", Sending SHUTDOWN signal to the NodeManager.";
LOG.info(message);
response.setDiagnosticsMessage(message);
response.setNodeAction(NodeAction.SHUTDOWN);
this.rmContext.getInactiveRMNodes().put(rmNode.getNodeID().getHost(),
rmNode);
return response;
}
{code}
> The RM can't update the Decommissioned Nodes Metric
