> Fix two bugs related to dynamic broker configs in KRaft
> -------------------------------------------------------
>
> Key: KAFKA-13835
> URL: https://issues.apache.org/jira/browse/KAFKA-13835
> Project: Kafka
> Issue Type: Bug
> Reporter: Colin McCabe
> Assignee: Colin McCabe
> Priority: Critical
> Labels: 4.0-blocker
>
> The first bug is that we were calling reloadUpdatedFilesWithoutConfigChange
> when a topic configuration was changed, but not when a broker configuration
> was changed. This was backwards -- this function must be called only for
> BROKER configs, and never for TOPIC configs. (Also, this function is called
> only for specific broker configs, not for cluster configs.)
> The second bug is that there were several configurations such as
> `max.connections` which were related to broker listeners, but which did not
> involve creating or removing new listeners. We can and should support these
> configurations in KRaft, since no additional work is needed to support them.
> Only adding or removing listeners is unsupported. This PR adds support for
> these by fixing the configuration change validation.
