Hi Aaron, This is the expected behavior of KIP-710. The relevant section reproduced here:
> Enabling a single Connect REST server in the MirrorMaker 2.0 node, only supporting the internal Connect endpoints. The endpoints that are typically exposed in a distributed Connect for creating connectors, getting status, etc are not enabled in dedicated mode, even with the new configuration. Only the internal endpoints that workers use to communicate with one another are enabled. If you want the other endpoints for getting the status, reconfiguring connectors, etc, I would recommend switching to the connect distributed mode and creating the MM2 connectors via the REST API. Hope this helps!
