---------------------------
Summary: Align broker and controller "advertised.listeners" and
"listeners" behaviour
Key: KAFKA-19515
URL: https://issues.apache.org/jira/browse/KAFKA-19515
Project: Kafka
Issue Type: Improvement
Reporter: 黃竣陽
Assignee: 黃竣陽
In the controller, we can configure the {{listeners}} setting as
{{{}CONTROLLER://0.0.0.0:9093{}}}, which means it will bind to all network
interfaces. If {{advertised.listeners}} is not explicitly set, the controller
will automatically infer it from the {{listeners}} value.
However, the behavior is different in the broker. If we set {{listeners}} to
{{{}PLAINTEXT://0.0.0.0:9093{}}}, the broker will throw an exception instead of
automatically inferring the {{advertised.listeners}} value.
We should align this behavior—either both should throw an exception when using
a wildcard address ({{{}0.0.0.0{}}}), or both should automatically infer
{{advertised.listeners}} from {{{}listeners{}}}.
