[~bobrik] In the scenario you described I assume some consumer id exists under the {{/ids}} path. By design, the consumer group (for old consumers) can be deleted only if there is no active consumer in the group. There are active consumers group in the group iff the path {{/ids}} exists for this group and there are consumer ids inside this path. If this is not what you're experiencing please advise and perhaps provide steps to reproduce. Thanks.

> In zookeeper I have:
> {noformat}
> [zk: foo(CONNECTED) 37] ls /kafka/logs/consumers/console-consumer-4107
> [offsets]
> {noformat}
> This consumer group also shows up when I list consumer groups:
> {noformat}
> $ /usr/local/kafka/bin/kafka-consumer-groups.sh --zookeeper foo:2181/kafka/logs --list | fgrep console-consumer-4107
> Note: This will only show information about consumers that use ZooKeeper (not those using the Java consumer API).
> console-consumer-4107
> {noformat}
> But I cannot remove this group:
> {noformat}
> $ /usr/local/kafka/bin/kafka-consumer-groups.sh --zookeeper 36zk1.in.pdx.cfdata.org:2181/kafka/logs --delete --group console-consumer-4107
> Note: This will only show information about consumers that use ZooKeeper (not those using the Java consumer API).
> Error: Delete for group 'console-consumer-4107' failed because group does not exist.
> {noformat}
> I ran tcpdump and it turns out that /ids path is checked:
> {noformat}
> $.e.........P.fP...&......<...........//kafka/logs/consumers/console-consumer-4107/ids.
> {noformat}
> I think kafka should not check for /ids, it should check for / instead here.
