Do you have nifi.cluster.node.address set to the hostname? I think that will bypass the issue. The actual issue has to do with how the hostname is auto detected, I think. Some things to check are that you have an appropriate entry in /etc/hosts for your hostname pointing back to it’s IP and that you don’t have an entry for the hostname pointing at 127.0.0.1.

At the single node cluster the ${hostname(true)} returns the FQDN but at my 3 node cluster it returns "localhost". Any ideas why??? Kind regards Jens M. Kofoed
