Question

这是关于this的后续问题。我设法做了以下事情：

为我的5代理Kafka集群创建无头服务以进行代理间通信
为每个经纪人设置一项服务
1. 每个服务都有一个外部IP
2. 每个服务仅选择一个广告连播，例如服务＆＃34; kafka-0-es＆＃34;选择pod＆＃34; kafka-0＆＃34;
pod正确宣传各自的外部IP。我通过访问ZooKeeper CLI上的数据来验证这一点。

我使用zkCli创建了一个主题test-topic并验证它已创建。之后，我开始了Kafka控制台制作人。

.\kafka-console-producer.bat --broker-list EXTERNAL_IP_1:9093,EXTERNAL_IP_2:9093,EXTERNAL_IP_3:9093,EXTERNAL_IP_4:9093,EXTERNAL_IP_5:9093 --topic test-topic --property parse.key=true --property key.

我的卡夫卡经纪人＆＃34; kafka-2＆＃34;根据Zookeeper的说法，这是该主题的领导者：

get /kafka/brokers/topics/test-topic/partitions/0/state

{"controller_epoch":5,"leader":2,"version":1,"leader_epoch":0,"isr":[2,1]}

但是pod kafka-2在Log

[2018-05-09 15:21:02,524] ERROR [ReplicaFetcherThread-0-2], Error for partition [test-topic,0] to broker 2:org.apache.kafka.common.errors.UnknownTopicOrPartitionException: This server does not host this topic-partition. (kafka.server.ReplicaFetcherThread)

不太确定为什么会这样，配置看起来很好。为了让我的Kafka集群在Kubernetes上运行，我还缺少什么？

请注意，我还试图彻底擦除我的群集（缩小kafka群集，删除kafka存储，缩小zk群集，删除zk存储，扩展zk，扩展kafka）但无济于事。< / em>
