Description

In zookeeper I have:

[zk: foo(CONNECTED) 37] ls /kafka/logs/consumers/console-consumer-4107
[offsets]

This consumer group also shows up when I list consumer groups:

$ /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

But I cannot remove this group:

$ /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.

I ran tcpdump and it turns out that /ids path is checked:

$.e.........P.fP...&......<...........//kafka/logs/consumers/console-consumer-4107/ids.

I think kafka should not check for /ids, it should check for / instead here.
