Hey Leo, Yes, the error that you are seeing is related to NIFI-2907. However, it's really more of a warning/informational message, even though it shows an ERROR-level log message. It should not affect your instance of NiFi in any way other than creating an annoying (and concerning) error message.
Can you look through your logs and see if you have any other errors that may be causing problems for you? I would recommend you look in both the nifi-app.log and the nifi-bootstrap.log.

One of '{processGroup, remoteProcessGroup, connection, controllerService}' is expected. It seems to correspond to this issue which is not fixed yet: https://issues.apache.org/jira/browse/NIFI-2907 Is there any workaround to be able to restart my NiFi cluster ? Is it possible to fix the schema ? Thanks Leo
