> Suppress stacktrace on connection refused when NiFi Registry is not running

> Key: NIFI-6201
> URL: https://issues.apache.org/jira/browse/NIFI-6201
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework, Extensions
> Affects Versions: 1.9.2
> Reporter: Andy LoPresto
> Assignee: Andy LoPresto
> Priority: Major
> Labels: beginner, error, log, registry

> When NiFi is running and the flow has a Registry Client configured to connect
> to the NiFi Registry, but the Registry instance is not running or is not
> avzailable, long stacktraces are output in the {{nifi-app.log}}. While these
> events are important, the long stacktraces are unnecessary as the cause is
> clear -- "Connection refused". These exceptions should be caught and logged
> properly.
