---------------------------------
Assignee: Luke Chen
> Talking to controllers via AdminClient requires reconfiguring controller
> listener
> ---------------------------------------------------------------------------------
>
> Key: KAFKA-16612
> URL: https://issues.apache.org/jira/browse/KAFKA-16612
> Project: Kafka
> Issue Type: Improvement
> Reporter: Gantigmaa Selenge
> Assignee: Luke Chen
> Priority: Major
>
> After KIP-919, Kafka controllers register themselves with the active
> controller once they start up. This registration includes information about
> the endpoints which the controller listener is configured with. This endpoint
> is then sent to admin clients (via DescribeClusterResponse) so that clients
> send requests to the active controller. If the controller listener is
> configured with "CONTROLLER://0.0.0.0:9093" , this will result in admin
> clients requests failing (trying to connect to localhost). This was not
> clearly stated in the KIP or the documentation.
> When clients talking to brokers, advertised.listeners is used, however
> advertised.listener is forbidden for controllers. Should we allow
> advertised.listeners for controllers so that admin client can use it to talk
> to controllers, in the same way it uses it to talk to brokers? Or should the
> endpoints provided in controller.quorum.voters, be returned to admin client?
> If the intention is to use the regular "listeners" configuration of
> controller for clients, this should be clearly documented.
