当我尝试使用Kafka 生产环境 者和消费者（0.9.0）脚本来推送/拉取主题中的消息时，我得到以下错误 .

生产环境 者错误

[2016-01-13 02:49:40,078] 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)

消费者错误

为什么我收到错误，我该如何解决？

配置

在 Docker containers on Mac 中运行所有组件 . ZooKeeper和Kafka在单独的Docker容器中运行 .

Docker Machine（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 . 我已经创建了一个主题，其中包含一个分区，复制因子为1 .

注意 leader designation is 0 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，我执行以下操作以发送一些消息：

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 02:51:40,081] ERROR Error when sending message to topic test with key: null, value: 13 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，这些消息产生了我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

我已确认端口 2181 和 9092 是打开的，可从Kafka Docker容器中访问：

root@f89a0b380f19:/# nc -z 192.168.99.100 2181; echo $?;
0
root@f89a0b380f19:/# nc -z 192.168.99.100 9092; echo $?;
0
