> Auto topic creation causes failure with older clusters

>                 Key: KAFKA-5704
>                 URL: https://issues.apache.org/jira/browse/KAFKA-5704
>             Project: Kafka
>          Issue Type: Bug
>          Components: KafkaConnect
>    Affects Versions:
>            Reporter: Ewen Cheslack-Postava
>            Assignee: Randall Hauch
>             Fix For:, 1.0.0
> The new automatic internal topic creation always tries to check the topic and 
> create it if missing. However, older brokers that we should still be 
> compatible with don't support some requests that are used. This results in an 
> UnsupportedVersionException which some of the TopicAdmin code notes that it 
> can throw but then isn't caught in the initializers, causing the entire 
> process to fail.
> We should probably just catch it, log a message, and allow things to proceed 
> hoping that the user has already created the topics correctly (as we used to 
> do).
