----------------------------------
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.
