---------------------------------------

             Summary: TopicMetadataRequest creates topic if it does not exist
                 Key: KAFKA-2887
                 URL: https://issues.apache.org/jira/browse/KAFKA-2887
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 0.8.2.0
         Environment: Centos6, Java 1.7.0_75
            Reporter: Andrew Winterman
            Priority: Minor


We wired up a probe http endpoint to make TopicMetadataRequests with a possible 
topic name. If no topic was found, we expected an empty response. However if we 
asked for the same topic twice, it would exist the second time!

I think this is a bug because the purpose of the TopicMetadaRequest is to 
provide  information about the cluster, not mutate it. I can provide example 
code if needed.
