当我尝试使用 Kafka 生产者和消费者 (0.9.0) 脚本从主题推送/拉取消息时，我收到以下错误。
生产者错误

消费者错误

为什么我会收到错误，我该如何解决？
配置
在 Mac 上运行 Docker 容器中的所有组件。ZooKeeper 和 Kafka 在不同的 Docker 容器中运行。
Docker 机器（boot2docker） IP 地址：192.168.99.100
ZooKeeper 端口：2181
Kafka 端口：9092
Kafka配置文件server.properties设置如下：
host.name=localhost
broker.id=0
port=9092
advertised.host.name=192.168.99.100
advertised.port=9092
命令
我从 kafka 服务器 Docker 容器中运行以下命令。我已经创建了一个具有一个分区和复制因子为 1 的主题。
请注意，领导者指定为 0，这可能是问题的一部分。
root@f89a0b380f19:/opt/kafka/dist# ./bin/kafka-topics.sh --zookeeper 192.168.99.100:2181 --topic test --describe
Topic:test PartitionCount:1 ReplicationFactor:1 Configs:
Topic: test Partition: 0 Leader: 0 Replicas: 0 Isr: 0
然后我执行以下操作来发送一些消息：
root@f89a0b380f19:/opt/kafka/dist# ./bin/kafka-console-producer.sh --broker-list 192.168.99.100:9092 --topic test
one message
two message
three message
four message

[2016-01-13 02:50:40,080] ERROR Error when sending message to topic test with key: null, value: 11 bytes with error: Failed to update metadata after 60000 ms. (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)

[2016-01-13 02:52:40,083] ERROR Error when sending message to topic test with key: null, value: 12 bytes with error: Failed to update metadata after 60000 ms. (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
这是我用来尝试使用消息的命令，它会产生我在上面发布的消费者错误。
root@f89a0b380f19:/opt/kafka/dist# ./bin/kafka-console-consumer.sh --zookeeper 192.168.99.100:2181 --topic test --from-beginning
我已经确认了端口2181，9092并且可以从 Kafka Docker 容器中打开和访问：
root@f89a0b380f19:/# nc -z 192.168.99.100 2181; echo $?;
0
root@f89a0b380f19:/# nc -z 192.168.99.100 9092; echo $?;
