Okay thanks I’ll check that state/local thing out. Drilling a little further on the main issue, it seems to boil down to NiFi on Server B having an UnknownHostException for the FQDN for Server B. I am just using /etc/hosts for the naming (no DNS in our server enclave) and of course I have confirmed spelling, etc. I even wrote a two line Java program that calls InetAddress.getAllByName, and passing it the same FQDN (copies and pasted from the nifi stack trace) resolves without a problem. So now I am really confused. I have rebooted Server B and that didn’t change anything. I also tried an alternate FQDN and that has the same behavior on Server B
Really confused now!
