I'm attempting to setup NiFi as a three node cluster (NCM on one host and a node each on two other hosts). I can see heartbeats in the all three logs but when I connect via url I receive "An unexpected error has occurred; No nodes were able to process this request." In logback.xml I've replaced every 'level="INFO"' with 'level="DEBUG"' but still only see a time out for an unspecified request in the NCM log. I've looked at both nifi-user.log and nifi-app.log on all three hosts. I've gotten a single NiFi instance working on a different host. After this, I need to setup a five node kerberized NiFi cluster.
