> * @return A future map from topic names to descriptions which can be
> used to check
> * the status of individual description if the describe topic
> request used
> * topic names, otherwise return null, this request succeeds only
> if all the
> * topic descriptions succeed
> {code}
> According the docs, it should return null if we try to get the result
> unmatched to the request. For example, we call `allTopicNames` in passing
> `TopicIdCollection`. However, the current implementation will throw NPE
> directly
