I did it in that way only because this is something new, so I though that
maybe you may want it to be configurable. But you are right I cannot think of a
case we would prefer to keep the unavailable partitions.
I'll update the PR to make it the default behaviour if it's ok for you.

> Originally reported in ML:
> [http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Dynamically-deleting-kafka-topics-does-not-remove-partitions-from-kafkaConsumer-td19946.html]
> The problem is that the Kafka consumer has no notion of "closed" partitions
> at the moment, so statically assigned partitions to the Kafka client is never
> removed and is always continuously requested for records.
> This causes LOG noises as reported in the reported mail thread.
