> Key: KAFKA-6338
> URL: https://issues.apache.org/jira/browse/KAFKA-6338
> Project: Kafka
> Issue Type: Test
> Affects Versions: 1.0.0
> Reporter: Ronald van de Kuil
> Priority: Minor
>
> I have just setup a kerberized Kafa cluster with Ranger 0.7.1 and Kafka
> 1.0.0.
> It all seems to work fine as I see that authorisation policies are enforced
> and auditlogging is present.
> On startup of a kafka server I see a stack trace but it does not seem to
> matter.
> My wish is to keep the logs tidy and free of false alerts.
> I wonder whether I have an issue somewhere.
