------------------------------------
Summary: Changes to nifi.properties file can result in node
failing to rejoin cluster.
Key: NIFI-2070
URL: https://issues.apache.org/jira/browse/NIFI-2070
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 0.6.1
Reporter: Matthew Clarke
Priority: Minor
I have a cluster with 5 connected nodes. If I edit the nifi.properties file
and specifically change one of the protocol ports, it will not rejoin cluster
on restart:
2016-06-21 14:49:49,600 WARN [main] o.a.nifi.controller.StandardFlowService
Connection request was blocked by cluster manager with the explanation: The
Node Identifier provided already belongs to node nifi-cluster-node:1444
WORKAROUND: If I go in to the cluster UI on the NCM and remove that
disconnected node completely from the cluster, it will rejoin on next restart.
I assume that triggers a new node identifier.
