----------------------------------------
Good idea.
> Streams smoke tests fails when there is only 1 broker

> Key: KAFKA-4625
> URL: https://issues.apache.org/jira/browse/KAFKA-4625
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Eno Thereska
> Assignee: Eno Thereska
> Fix For: 0.10.2.0

>
> The streams smoke test fails when we have a single broker since by default it
> requires a replication factor of 2. So in StreamsKafkaClient:createTopics we
> can get an INVALID_REPLICATION_FACTOR code.
> As part of this commit, it appears we do not check the number of brokers
> available and thus fail if there aren't enough brokers (check for
> getBrokers() in here:
