> Why do we always create an admin client with the same "connector-dlq-adminclient-" value id?
> [https://github.com/apache/kafka/blob/trunk/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/Worker.java#L1008]
> For all other cases, a postfix is added.

>  I get "Error registering AppInfo mbean
> javax.management.InstanceAlreadyExistsException: kafka.admin.client:type=app-info,id=connector-dlq-adminclient-." error for all tasks.
> It looks like the ConnectorTaskId should be added.
