I am new to Nifi and trying to learn how to use it. I have set up two servers with Nifi and configured them to be a cluster. I am currently having two issues that I think are related. 1 - If I take one server off line I can not access Nifi. 2 - If I set a work process to execute on "Primary node", it dose not run. If I set it to "All nodes" then I get two copes of the work. Any help would be appreciated. I have included what I think is the pertinent data from both servers for /conf/nifi.properties, /conf/zookeep.properties, and /state/zookeeper/myid. Thank you.
