-------------------------------------------
Summary: Import from registry changes existing parameters when not
allowed
Key: NIFI-16318
URL: https://issues.apache.org/jira/browse/NIFI-16318
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 2.11.0
Environment: OS: RedHat (RedHat 8.10)
Kernel: 4.18.0
CPUs: 4 (Intel(R) Xeon(R) Gold 6348 CPU @ 2.60GHz)
GitLab integration via the GitLabFlowRegistryClient
Reporter: Sven Van Kerrebroeck

When getting a flow from registry (gitlab integration) and leaving the "Keep
existing Parameter Contexts" checked, still NiFi tries to change some
parameters.

In a previous trial, when no other flows were running, it actually did change
the parameter to the value from the registry. In the example above another flow
was running, so it couldn't change it.
The flow was not imported and the only way to import is to stop the other
existing flow and let it update the parameter... This is dangerous and can
result in wrong processing if parameters change to other values.
Expected behaviour: existing parameters should NEVER be overwritten when the
option is checked.
I've never noticed this behaviour in older nifi versions (v1)
