Paresh, In the top-right-hand corner of the NiFi UI, there is a Cluster Management icon. I believe it is the next-to-last icon there.If you click on that icon, you will be given a dialog that shows all nodes in the cluster, and you can click the "Disconnect" iconto remove a node from the cluster entirely. Generally, though, the easiest way to bring that node back into the cluster is to remove the flow.xml.gz file from the conf/ directoryand restart the node. NiFi does not do this automatically because there are cases when the user wants to intentionally disconnecta node from the cluster for diagnostic purposes, etc. and will have modified the flow. However, if you want to just bring it back upto speed with the rest of the nodes in your cluster, it's safe to just remove the file and restart. Thanks-Mark
