Kuhu Shukla commented on YARN-4386:
-----------------------------------
Thank you [~djp] for your comments.
TestClientRMTokens is failing regardless of the patch, tracked through
YARN-4306.
TestAMAuthorization fails the same way and I believe is tracked through
YARN-4318.
No tests were attached since the final outcome of this patch remains unchanged
and a decommissioned node stays in that state regardless.
[~sunilg], [~djp], request for review. Thanks a lot.

> In refreshNodesGracefully(), during recommissioning, the entryset from
> getRMNodes() which has only active nodes (RUNNING, DECOMMISSIONING etc.) is
> used for checking 'decommissioned' nodes which are present in
> getInactiveRMNodes() map alone.
> {code}
> for (Entry<NodeId, RMNode> entry:rmContext.getRMNodes().entrySet()) {
> .........................
> // Recommissioning the nodes
> if (entry.getValue().getState() == NodeState.DECOMMISSIONING
> || entry.getValue().getState() == NodeState.DECOMMISSIONED) {
> this.rmContext.getDispatcher().getEventHandler()
> .handle(new RMNodeEvent(nodeId, RMNodeEventType.RECOMMISSION));
> }
> {code}
