… defined (apache#21918) Kafka can incorrectly resolve the advertised listener for controllers if it is not specified. For controller configurations that specify the controller.quorum.voters but not the advertised.listener, Kafka can deduce the advertise listener for the default listener. In this cases, Kafka will automatically set the advertised listener for the default listener to the endpoint specified in controller.quorum.voters.
