Thanks Pierre and Mark for your answers.

I managed to remove the template from flow.xml.gz and got rid of the error.
But my access issue was somewhere else. It was a firewall config change.

Thanks and best regards

Hey Leo,

Yes, the error that you are seeing is related to NIFI-2907. However, it's really more of a
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.

I am running a NiFI cluster and it happened to be blocked on restart with the following error.

2017-01-05 11:18:53,224 ERROR [NiFi logging handler] org.apache.nifi.StdErr [Error] :42201:38:
cvc-complex-type.2.4.a: Invalid content was found starting with element 'template'. One of
'{processGroup, remoteProcessGroup, connection, controllerService}' is expected.

It seems to correspond to this issue which is not fixed yet:

Is there any workaround to be able to restart my NiFi cluster ?
Is it possible to fix the schema ?
