huxi commented on KAFKA-4675:
-----------------------------
Seems deleting '/brokers/topics/<topic>' comes fourth from the bottom during
the topic deletion while creating it comes top front in createTopic logic, did
you encounter the TopicExistsException that failed the creation?
> Subsequent CreateTopic command could be lost after a DeleteTopic command

> Key: KAFKA-4675
> URL: https://issues.apache.org/jira/browse/KAFKA-4675
> Project: Kafka
> Issue Type: Bug
> Reporter: Guozhang Wang
> Labels: admin
>
> This is discovered while investigating KAFKA-3896: If an admin client sends a
> delete topic command and a create topic command consecutively, even if it
> wait for the response of the previous command before issuing the second,
> there is still a race condition that the create topic command could be "lost".
> This is because currently these commands are all asynchronous as defined in
> KIP-4, and controller will return the response once it has written the
> corresponding data to ZK path, which can be handled by different listener
> threads at different paces, and if the thread handling create is faster than
> the other, the executions could be effectively re-ordered.
