> NiFi starting failure and key file already existing
> ---------------------------------------------------
>
> Key: NIFI-4150
> URL: https://issues.apache.org/jira/browse/NIFI-4150
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.2.0, 1.3.0
> Reporter: Pierre Villard
>
> In some cases, if NiFi cannot start (in my case: debug port was already in
> use), the key file is still created and not deleted. Then it won't be
> possible to restart NiFi unless the key file is manually deleted.
