Andrew Winterman commented on KAFKA-2887:
-----------------------------------------
In that case, shouldn't it be mentioned in the documentation for the request?
We were looking at
https://cwiki.apache.org/confluence/display/KAFKA/A+Guide+To+The+Kafka+Protocol#AGuideToTheKafkaProtocol-TopicMetadataRequest
when we wrote it.
> 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.
