apache-kafka - Kafka消费者在Mesos上运行时出现 "Failed to add leader for partitions"错误

Question

我正在使用mesos/kafka运行一个由6个代理组成的Kafka集群。图书馆。我能够在 6 台不同的机器上添加和启动代理，并使用 Python SimpleProducer 和 kafka-console- Producer.sh 脚本将消息发布到集群中。

但是我无法让消费者正常工作。我正在运行以下消费者命令:

bin/kafka-console-consumer.sh --zookeeper 192.168.1.199:2181 --topic test --from-beginning --consumer.config config/consumer.properties --delete-consumer-offsets

在consumer.properties 文件中，我将group.id 设置为my.group 并将zookeeeper.connect 设置为zookeeper 集合中的多个节点。我从运行此消费者时收到以下警告消息:

我不知道为什么它无法添加领导者，领导者似乎已经在 Zookeeper 中了。除了所有这些错误消息之外，我只能向消费者发送一条消息。字符串 {'some':2} 是我从控制台生成器发送的消息。

我在其中一个 Mesos 从服务器的 server.log 中发现了此错误，不确定它是否相关:

对于消费者可能发生的情况或我可能在哪里解决问题有什么建议吗？

Zookeeper 代理日志分区之一的分区状态:

[zk: localhost:2181(CONNECTED) 166] get /brokers/topics/test/partitions/0/state
{"controller_epoch":1,"leader":0,"version":1,"leader_epoch":0,"isr":[0]}

操作系统:Ubuntu 14.0.4金币:0.23卡夫卡:2.10-0.8.2.1

更新:使用 kafka-console-consumer.sh 进行一些进一步的测试，消息似乎确实能够通过。错误消息是恒定的，因此您不会在 stdout 中看到所有消息。 Python KafkaConsumer 立即失败，并出现 FailedPayloadsError。

我认为您需要研究属性“advertized.host.name”的值。我最近也遇到了这个问题并使用上述属性进行了修复。
请确保您为每个经纪商提供了正确的IP地址。
如果不起作用请告诉我。
