Matthew de Detrich commented on KAFKA-12430:
--------------------------------------------
I think I might just create a second property to not create topics and document
that it will break upstream clusters.
> emit.heartbeats.enabled = false should disable heartbeats topic creation

> Key: KAFKA-12430
> URL: https://issues.apache.org/jira/browse/KAFKA-12430
> Project: Kafka
> Issue Type: Bug
> Components: mirrormaker
> Reporter: Ivan Yurchenko
> Assignee: Matthew de Detrich
> Priority: Minor
>
> Currently, whether MirrorMaker 2's {{MirrorHeartbeatConnector}} emits
> heartbeats or not is based on {{emit.heartbeats.enabled}} setting. However,
> {{heartbeats}} topic is created unconditionally. It seems that the same
> setting should really disable the topic creation as well.
