How to configure Kafka to use a running zookeeper instance?

[Hussein Baghdadi]

Hi,
I'm using Storm (https://github.com/nathanmarz/storm) that is already requires 
zookeeper instance to be running.Kafka also needs an instance of zookeeper.
Is it possible to configure Kafka to make use of the zookeeper needed by 
Storm?No need to run two zookeepers, I think.
Thanks.
