I am trying to create a load balanced cluster with 2 node (experimenting on dev nifi 1.8).
After, I start the nifi services on the 2 nodes, with the zookeeper. I observer that the cluster elects the Primary node, and then nifi terminates with the following error: 2018-12-04 14:20:05,949 ERROR [main] o.a.nifi.controller.StandardFlowService Failed to load flow from cluster due to: org.apache.nifi.cluster.ConnectionException: Failed to connect node to cluster due to: java.io.IOException: Could not begin listening for incoming connections in order to load balance data across the cluster. Please verify the values of the 'nifi.cluster.load.balance.port' and 'nifi.cluster.load.balance.host' properties as well as the 'nifi.security.*' properties nifi.cluster.load.balance.host is not set, nifi.cluster.load.balance.port is set to 8080, the same where nifi service UI is running. A big picture on how these values are used by nifi will help greatly. Thanks, - Vishal
