Beletsky Andrey updated KAFKA-1958:
-----------------------------------
Description:
We use kafka with ZooKeeper via high level consumer.
There is a scheduled job that creates a consumer with specific group, does
necessary logic and shuts down this consumer.
An issue:
Nobody deletes */consumers/myGroup/ids/myGroup_<ip>_<postfix>*. And after
several job runs there are a lot of dead consumer IDs under myGroup. I've got
[an
issue|https://cwiki.apache.org/confluence/display/KAFKA/FAQ#FAQ-Whysomeoftheconsumersinaconsumergroupneverreceiveanymessage?]
that new consumer doesn't see a partition.
We start to implement an approach to remove a consumer nodes from Zookeeper
manually after consumer is shutted down.
I think better way to remove this node during
*ZookeeperConsumerConnector.shutdown()*.
*P.S.:*
If I missed something in your sources please let me know.
