kafka新版本2.1.0代理无故挂起

时间：2019-04-23 09:18:31

标签： apache-kafka kafka-consumer-api

起初，集群中的所有代理都可以启动并正常工作，但是有时其中一个代理会遇到问题。并且会出现一些现象：

  • 整个集群都挂起了，生产者和消费者也没有工作，因此监控器的网络流量降到了零；
  • 使用kafka-topic.sh描述主题消息，每个副本都很好，即使是特殊的Brokerid，zk中的信息也很正常；
  • 在不正常的代理上，文件描述号逐渐增加，可从/ proc / sys / fs / file-nr读取
  • netstat代理侦听端口9092显示很多“ CLOSE_WAIT”状态

以下是来自其他代理的错误日志，而异常的代理日志看不到任何异常。

-Xmx8G -Xms8G，这是jvm堆大小。我只能杀死-9个实例，然后重新启动以恢复它。

  • 版本kafka_2.12-2.1.0
  • java

答案 0 :(得分：0)

这是在kafka 2.1.0上报告的问题。请检查https://issues.apache.org/jira/browse/KAFKA-7802了解详情。它被https://issues.apache.org/jira/browse/KAFKA-7697标记为重复，该问题已在kafka 2.2.0中修复，因此升级kafka版本应该会有所帮助。
