We are running 1.8 processors, and in the queue following our ListFile and GetFile processors are trying to configure "Round robin" load balancing.
We have four nodes in our cluster. At present let's say the primary has a UI URL of https://8.93.20.100:8443. The three other nodes are similar, with 101, 102, and 103. I have load balancing in nifi.properties configured to use port 6342, which is open on my hosts. Load balancing is failing. All the flowfiles stay on the primary node. The log says this, once for each partner node we are trying to balance with: Unable to connect to 8.93.20.101:8443 for load balancing java.net.NoRouteToHostException: No route to host In nifi.properties I have tried three ways of setting nifi.cluster.load.balance.host, none of which resolved the problem: 1. I left it blank, and let it use its default which is nifi.cluster.node.address 2. I attempted to use the host name, which for each is something like this: abc-def-nic01i [02i, 03i, and 04i on those hosts] . My host names resolve to IPs in local node /etc/host files that have 6342 open on them. 3. I tried using the IP value the name alias maps to, putting it directly in this config parm What is this error telling me, and how do I fix this so that I can employ load balancing properly in my cluster configuration? Thank you in advance for any help.
