If you want to pull broker or other-kafka information from Zookeeper then kafka.utils.ZkUtils provides a nice interface. Here is the code I have to list all zookeeper brokers (there are a ton of other methods there):

List listBrokers() {

        final ZkConnection zkConnection = new ZkConnection(connectionString);
        final int sessionTimeoutMs = 10 * 1000;
        final int connectionTimeoutMs = 20 * 1000;
        final ZkClient zkClient = new ZkClient(connectionString,
                                               sessionTimeoutMs,
                                               connectionTimeoutMs,
                                               ZKStringSerializer$.MODULE$);

        final ZkUtils zkUtils = new ZkUtils(zkClient, zkConnection, false);

        scala.collection.JavaConversions.seqAsJavaList(zkUtils.getAllBrokersInCluster());
}
