报错原因：消费监听接口监听的主题不存在时，默认会报错

解决方法：

配置文件中将listener的属性missingTopicsFatal设置为false

spring:
  kafka:
    listener:
      missing-topics-fatal: false

kafka常见报错警告异常解决

1.自行修改server.properties中broker id后造成与meta.properties中数据不匹配

kafka.common.InconsistentBrokerIdException: Configured broker.id 2 doesn't match stored broker.id 1 in meta.properties. If you moved your data, make sure your configured broker.id matches. If you intend to create a new broker, you should remove all data in your data directories (log.dirs).

2.__consumer_offsets这个topic是由kafka自动创建的，默认49个，这个topic是不能被删除的！

Error while executing topic command : Topic __consumer_offsets is a kafka internal topic and is not allowed to be marked for deletion.

为什么这里会是这样存储__consumer_offsets的呢：

• [1.] 将所有 N Broker 和待分配的 i 个 Partition 排序
• [2.] 将第 i 个 Partition 分配到第(i mod n)个 Broker 上

3.删除topic时

Topic frist is already marked for deletion.

彻底删除topic：

• [1. ] 删除Topic，delete.topic.enable=true这里要设置为true
• [2. ] 删除log日志
• [3. ] 删除ZK中的Topic记录

命令：./bin/zkCli.sh

找到topic所在的目录：ls /brokers/topics

执行命令：rmr /brokers/topics/{topic name}即可，此时topic被彻底删除。

另外被标记为marked for deletion的topic你可以在zookeeper客户端中通过命令获得：ls /admin/delete_topics/{topic name}，如果你删除了此处的topic，那么marked for deletion 标记消失

当然，这里是你delete.topic.enable设置为false时Zookeeper下才会有这个节点。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持我们。
