> ------------------------------------------------------------------

> Key: KAFKA-5789
> URL: https://issues.apache.org/jira/browse/KAFKA-5789
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.11.0.0
> Reporter: Takafumi Saito
> Priority: Major
> Labels: needs-kip

> When setting auto.create.topic.enbale true in broker, some deleted topics
> will be re-created.
> Because when consumer that subscribe deleted topic is exist, broker will
> create topic having same name.
> It is not necessary that consumers trigger new topic creation , so auto topic
> creation in consumer should be disabled.
> I attatch the log outputted in our broker.
> This show that a topic (topic_1) was deleted at 12:02:24,672, but same topic
> was created shortly thereafter:
