Andrew Lim created NIFI-1991:
--------------------------------
Summary: Zero Master Cluster: Modifying a disconnected node
causes other nodes to not be able to join cluster
Key: NIFI-1991
URL: https://issues.apache.org/jira/browse/NIFI-1991
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Andrew Lim
Priority: Blocker
Fix For: 1.0.0
I created a zero master cluster with 3 nodes. All three were up and running.
I stopped all 3 instances and then brought up just Node1.
In the Node1 UI, I made some edits to the flow.
I attempted but was not able to bring up Node2 and Node3 to join the cluster.
Here is what I saw in the logs:
