Randall Hauch resolved KAFKA-5669.
----------------------------------
Resolution: Duplicate
> Define allowed characters for connector names
> ---------------------------------------------
>
> Key: KAFKA-5669
> URL: https://issues.apache.org/jira/browse/KAFKA-5669
> Project: Kafka
> Issue Type: Improvement
> Components: KafkaConnect
> Affects Versions: 0.11.0.0
> Reporter: Sönke Liebau
> Assignee: Sönke Liebau
> Priority: Minor
>
> There are currently no real checks being performed against connector names
> and thus a lot of characters are allowed that create issues subsequently when
> trying to query connector state or delete connectors.
> KAFKA-4930 blacklists a few of the obvious culprits but is far from a final
> solution.
> We should come up with a definitive set of rules for connector names that can
> then be enforced.
> Kafka is very restrictive where topic names are concerned, it only allows the
> following characters: a-zA-Z0-9._-
> For Connect we may want to be a bit more forgiving, but probably not too much
> so, to avoid having to go back and fix things that were missed multiple times.
