How to create the initial zookeeper chroot path for zk.connect?
Sorry as I am new to Kafka/ZK, but the instruction seems not clear..

In the config, it was said that we can use a chroot-ed ZK (
http://kafka.apache.org/configuration.html), e.g. localhost:2181/kafka

But when I start the Kafka using the setting, it was showing..

java.lang.IllegalArgumentException: Path length must be > 0

In an old post (
http://mail-archives.apache.org/mod_mbox/incubator-kafka-users/201205.mbox/%3CCAK152briB=M-OaeaQtCz+[EMAIL PROTECTED]%3E)
it was saying I need to create the path first, so I use zkCli.sh to connect
to the ZK, and run the command

>> create /kafka ''

I restarted the Kafka and still the same error, any idea?

Thanks.
