Hello,
I tried upgrading NiFi from version 1.1.0.2.1.4.0-5 to NiFi version 1.2.0.3.0.0.0-453 of HDF 3.0 but I am having an issue when the node joins the cluster. I run a cluster with three NiFi nodes, I was trying a rolling upgrade to not stop all the nodes at the same time. I upgraded one of the nodes and tried to make it join the cluster. The node seemed to start up fine with no issues and said that the cluster had received the heartbeat. However, after the node joined the cluster the UI page in all three nodes started showing an error message saying "Unexpected error please check the logs for any errors". I went to the logs and I found the following warnings:

However in the app-log file after those warnings everything else seemed to start up fine and the node was connected to the cluster, I was just not able to access the UI from any of the nodes. I saw no errors or warnings in the bootstrap or user logs. I wanted to see if there could be something wrong that I am doing to the cluster with the node configuration or if the problem is that I would have to upgrade all the nodes and start them together all in the same NiFi version 1.2.0.3.0.0.0-453 of HDF 3.0? Any insights on this would be incredible helpful.
