--------------------------------
Status: Patch Available (was: Open)
> New consumer's subscribe(Topic...) api fails if called more than once
> ---------------------------------------------------------------------
>
> Key: KAFKA-2413

> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Reporter: Ashish K Singh
> Assignee: Onur Karaman

> I believe new consumer is supposed to allow adding to existing topic
> subscriptions. If it is then the issue is that on trying to subscribe to a
> topic when consumer is already subscribed to a topic, below exception is
> thrown.
