removing a kafka consumer group in zookeeper

Question

I'm using kafka_2.9.2-0.8.1.1 with zookeeper 3.4.6.

Is there a utility that can automatically remove a consumer group from zookeeper? Or can I just remove everything under /consumers/[group_id] in zookeeper? If the latter, is there anything else I'm missing & can this be done with a live system?

Update: As of kafka version 2.3.0, there is a new utility:

> bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --delete --group my-group

As of v0.9.0, Kafka ships with a suite of tools in the /bin one of which is the kafka-consumer-groups.sh tool. This will delete a consumer group. ./kafka-consumer-groups.sh --zookeeper <zookeeper_url> --delete --group <group-name>
