Subject [jira] [Created] (KAFKA-4295) kafka-console-consumer.sh does not delete the temporary group in zookeeper

Sswater Shi created KAFKA-4295:
----------------------------------

             Summary: kafka-console-consumer.sh does not delete the temporary group in zookeeper
                 Key: KAFKA-4295
                 URL: https://issues.apache.org/jira/browse/KAFKA-4295
             Project: Kafka
          Issue Type: Bug
          Components: admin
    Affects Versions: 0.10.0.1, 0.10.0.0, 0.9.0.1
            Reporter: Sswater Shi
            Priority: Minor


I'm not sure it is a bug or you guys designed it.

Since 0.9.x.x, the kafka-console-consumer.sh will not delete the group information in zookeeper/consumers
on exit when without "--new-consumer". There will be a lot of abandoned zookeeper/consumers/console-consumer-xxx
if kafka-console-consumer.sh runs a lot of times.

When 0.8.x.x,  the kafka-console-consumer.sh can be followed by an argument "--group". If
not specified, the kafka-console-consumer.sh will create a temporary group name like 'console-consumer-xxxx'.
If the group name is specified by "--group", the information in the zookeeper/consumers will
be kept on exit. If the group name is a temporary one, the information in the zookeeper will
be deleted when kafka-console-consumer.sh is quitted by Ctrl+C. Why this is changed from 0.9.x.x.
