Hi Neha, "Wipe out the cluster" Do you mean you uninstall the cluster and reinstall it? Or you just delete all kafka data and zookeeper data for the cluster? This is not a blocking issue for us. Our blocking issue is that some broker will fall out of ISR and never get back to it. We have observed that from more that one clusters. I am not sure if it is related to the deleting issue.

In test environments, if we have to delete topics, we wipe out the cluster. If this is a feature that most users are blocked on, I think it makes sense to prioritize https://issues.apache.org/jira/browse/KAFKA-330.
