在eclipse中编写kafka生产者代码时，我得到了下面提到的一个错误，在这里我想编写一个简单的生产者代码并在kafka控制台上显示消息consumer我启动了zookeeper和kafka服务器并完美地创建了topic。
代码如下：

import java.util.Properties;
import kafka.javaapi.producer.Producer;
import kafka.producer.KeyedMessage;
import kafka.producer.ProducerConfig;

public class ProducerTest {
    public static void mian(String ar[]){
        Properties prop=new Properties();

        prop.put("zk.connect","localhost:2181");
        prop.put("serializer.class","kafka.serializer.StringEncoder");
        prop.put("metadata.broker.list","localhost:9092");

        ProducerConfig config=new ProducerConfig(prop);

        Producer producer=new Producer(config);

        String msg="Sa resta rasta ra";

        producer.send(new KeyedMessage("test",msg));
    }
} 

Missing required argument "[authorizer-properties]"
Option                                  Description                            
----*emphasized text*--                                  -----------                            
--add                                   Indicates you are trying to add ACLs.  
--allow-host <allow-host>               Host from which principals listed in --
                                       allow-principal will have access. If 
                                        you have specified --allow-principal 
                                         then the default for this option     
                                          will be set to * which allows access 
                                          from all hosts.                      
--allow-principal <allow-principal>     principal is in principalType:name     
                                         format. User:* is the wild card

任何人请帮我解决这个错误。
