@Benjamin Hopp What reason if NiFi giving in the nifi-app.log for the node disconnections? Rather then restarting the node that disconnects, did you try just clicking the reconnect icon in the cluster UI? Verify that your nodes do not have trouble communicating with each other. Makes there are no firewalls between the nodes affecting communications to the HTTP/HTTPS ports: nifi.web.http.host=nifi-ambari-08.openstacklocal nifi.web.http.port=8090 nifi.web.https.host=nifi-ambari-08.openstacklocal nifi.web.https.port=9091 or node communication port: nifi.cluster.node.address=nifi-ambari-08.openstacklocal nifi.cluster.node.protocol.port=9088 Make sure Both yo r nodes are properly configured to talk to ZK and neither has issues communicating with them: nifi.zookeeper.connect.string=nifi-ambari-09.openstacklocal:2181,nifi-ambari-07.openstacklocal:2181,nifi-ambari-08.openstacklocal:2181 nifi.zookeeper.connect.timeout=3 secs nifi.zookeeper.root.node=/nifi nifi.zookeeper.session.timeout=3 sec All of the above setting are in the nifi.properties file.
