    RedisClient redisClient = new DefaultRedisClient(channel, this);
    redisClients.put(channel, redisClient);
    redisClient.addObserver(new Observer() {

        @Override
        public void update(Object args, Observable observable) {
            if (args instanceof RedisSlave) {
                becomeSlave(((RedisClient) observable).channel(), (RedisSlave) args);
            }
        }
    });
    return redisClient;
}
