---------------------------------

             Summary: refreshNodesGracefully() looks at active RMNode list for recommissioning
decommissioned nodes
                 Key: YARN-4386
                 URL: https://issues.apache.org/jira/browse/YARN-4386
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 3.0.0
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla


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}
