> A client sends topic creation request to broker.
> Another client sends the same topic creation request to broker.
> The former request does not finish. However, the second client get
> TopicExistsException.
> The root cause may be that topic is registered in zookeeper, but the data is
> not persisted and topic is not transfer to the paritition. At this time,
