我是Kafka的新手。我对Kafka的配置有疑问。
我想使用下面这样的独立服务器，
服务器1:Kafka制作人服务器2:Kafka经纪人、Kafka消费者、Zookeeper
但是，我不能给经纪人发信息。我收到了错误信息。
在控制台生产者（服务器1）上，控制台标准输出错误消息`

[2016-05-24 16:41:11,823] ERROR Error when sending message to topic twitter with key: null, value: 3 bytes with error: Failed to update metadata after 60000 ms.(org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)

在kafka producer（server2）上，控制台stdout错误消息

[2016-05-25 10:20:01,588] DEBUG Connection with /192.168.50.142 disconnected (org.apache.kafka.common.network.Selector)

运行命令如下 Kafka目录上的服务器1

./bin/zookeeper-server-start.sh config/zookeeper.properties
./bin/kafka-server-start.sh config/server.properties
./bin/kafka-console-consumer.sh --zookeeper 192.168.50.142:2181 --from-beginning --topic twitter
./bin/kafka-topics.sh --create --zookeeper 192.168.50.142:2181 --replication-factor 1 --partitions 1 --topic twitter

Kafka目录上的服务器2

./bin/kafka-console-producer.sh --broker-list 192.168.50.142:9092 --topic twitter

我的配置是， 服务器1（ip:192.168.50.155）： Kafka/config/producer.properties

metadata.broker.list=192.168.50.142:9092
producer.type=sync
compression.codec=none
serializer.class=kafka.serializer.DefaultEncoder

服务器2（ip:192.168.50.142）： kafka/config/zookeeper.properties文件

dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0

kafka/config/server.properties文件

`
Kafka2.11-0.9.0.0 java 1.8.0\u 60节点v4.4.4
我是否需要更改任何配置？请帮忙。
