title: How to remove a Kafka consumer group from a specific topic?
body: <p>I changed the consumer-group-id of my web service listening to a Kafka topic. Now, the old group id is still registered to the topic, but there is no consumer with that group id. Therefore, it is lagging. How can I remove a specific consumer group from a specific topic?</p>
  <p>I tried this:</p>
  <p><code>kafka-consumer-groups --bootstrap-server kafka01.myserver.com:9092 --topic notification-topic --delete --group old-consumer-group --execute</code></p>
  <p>But it returns: &quot;<em>The consumer does not support topic-specific offset deletion from a consumer group.</em>&quot;</p>
  <p>Should I remove the consumer group totally? I use the same group id listening to other topics, are they going to be affected?</p>
