[jira] [Commented] (KAFKA-2887) TopicMetadataRequest creates topic if it does not exist

    [ https://issues.apache.org/jira/browse/KAFKA-2887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16162853#comment-16162853 ] 

Manikumar commented on KAFKA-2887:
----------------------------------

As of  0.11.0.0,  We added a "allow_auto_topic_creation" flag to the topic meta data request (MetadataRequest) in KAFKA-5291. Also AdminCleint supports createTopic APIs. If this covers the JIRA requirement, then we can close this issue.

>          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.
