I resolved this, but realized I should add onto Mike's comment for anyone
else who looks back at this.
The Ambari tooltip just documents the Kafka behavior, rather than being an
indication of something Ambari handles. The latest Ambari tooltip doesn't
reference the min behavior anymore, because it no longer occurs.
> Full dev kafka has offsets.topic.replication.factor set to 3 instead of 1

>
> I saw an issue where no data was flowing through any topologies. A repeated
> error in kafka showed offsets.topic.replication.factor being too low. We
> should default this on full dev to 1 to avoid this issue.
> On further investigation, it looks like this setting changes between kafka
> versions and will no longer auto create the offset topic on some versions if
> the replication factor is too high, preventing data from flowing through.
