作为一名AI语言模型,无法直接获得您的代码以检查并排除问题。但是,根据错误信息,您可以尝试以下解决方法:
1. 检查代码是否存在任何拼写错误或语法错误,并纠正它们。
2. 确保对象_router被正确实例化,并已成功实例化。
3. 找到init()函数的定义,并确保在_router对象中调用该函数。如果没有定义init()函数,实现或导入必要的代码以定义它。
如果仍然存在问题,请检查您的日志以获取有关更详细信息,并尝试使用调试工具或与同事或开发人员一起查看代码以解决问题。

span exec error for kafka org.apache.kafka.common.errors.NotLeaderOrFollowerException: For requests intended only for the leader, this error indicates that the broker is not the current leader. For requests intended for any replica, this error indicates that the broker is not a replica of the topic partition.
这个错误是 Kafka 的一个常见错误,称为 `NotLeaderOrFollowerException`。它表示发起的请求要么是针对 Leader 执行的,但当前 broker 不是 Leader,要么是针对副本执行的,但当前 broker 不是该主题分区的副本。
这种情况可能发生在以下几种情况下:
1. 分区领导者切换:Kafka 分区可能会发生领导者切换,如果请求发送到了非领导者节点,就会出现该错误。
2. 副本同步延迟:Kafka 副本同步可能存在延迟,当请求发送到延迟的副本时,就会出现该错误。
3. 分区不可用:如果分区正在进行重新分配、数据迁移或者处于其他异常状态,可能会导致请求无法处理。
要解决这个问题,可以尝试以下几个步骤:
1. 确认分区状态:检查分区的状态是否正常,包括领导者和副本的状态。
2. 等待分区恢复:如果是因为分区切换或副本同步延迟引起的错误,可以等待一段时间,让分区状态恢复正常。
3. 检查集群健康状况:确保 Kafka 集群的各个节点正常运行,并且网络连接正常。
4. 检查配置:确保 Kafka 相关参数的配置正确,并且与实际情况相匹配。
如果问题仍然存在,建议查看 Kafka 的日志文件以获取更详细的错误信息,并根据实际情况进一步调查和排除故障。
