Bravo Zhang commented on SPARK-18272:
-------------------------------------

Does "subscribing topic by pattern with topic deletions" in KafkaSourceSuite 
already cover this case? It also has topic creation.

> Test topic addition for subscribePattern on Kafka DStream and Structured 
> Stream

> We've had reports of the following sequence
> - create subscribePattern stream that doesn't match any existing topics at 
> the time stream starts
> - add a topic that matches pattern
> - expect that messages from that topic show up, but they don't
> We don't seem to actually have tests that cover this case, so we should add 
> them
