Rick, Welcome to the community!
We seem to be a little short in the documentation department for how to make use of Remote Process Groups, but will look to remedy that. Just to confirm a few settings, both your nodes have a nifi.remote.input.socket.port set and each has nifi.remote.input.secure set to false within your nifi.properties. >From here, are you referencing the remote node via its UI address? Out of the box, this would be <server FQDN/IP>:8080/nifi Thanks, Aldrin On Sat, Aug 15, 2015 at 4:11 PM, Rick Braddy <[email protected]> wrote: > Hi, > > > > I’m new to NiFi, trying to get my first Remote Process Group configured > and working between two CentOS nodes.
