Thank you for your help. I deleted the flow.xml.gz . So now I have the NCM on machine 'b' and a node on machine 'c'. I start up a and then start up b. In b's logs I see logs of heartbeats: 2015-12-18 14:41:05,807 INFO [Process NCM Request-10] o.a.n.c.p.impl.SocketProtocolListener Finished processing request 790c06c7-6857-4a90-9d4f-76ec99159369 (type=HEARTBEAT, length=3250 bytes) in 2 millis
On machine c is also see heartbeats: 2015-12-18 14:39:55,741 INFO [Clustering Tasks Thread-3] org.apache.nifi.cluster.heartbeat Heartbeat created at 2015-12-18 14:39:55,664 and sent at 2015-12-18 14:39:55,741; send took 6 millis Everything seems fine. Then I try to view NiFi on the NCM which I set the web to: nifi.web.http.port=8089 http://machine-b.mitre.org:8089/nifi/ I see: An unexpected error has occurred No nodes were able to process this request. I don't see anything in the logs to suggest what went wrong.
