Question

Kafka群集具有3个代理（版本：1.1.0），并且运行了6个月以上。

然后我们在2018/12/12之后将每个主题的分区从3修改为48，然后经纪人每5-10天关闭一次。

然后，我们将经纪人从1.1.0升级到2.1.0，但是经纪人仍然每5-10天关闭一次。

每次，一个代理在以下错误日志后关闭，然后在几分钟后，其他2个代理也关闭，并具有相同的错误，但其他分区日志文件。

如果您尚未更改log.retention.bytes或log.retention.hours或log.retention.minutes或log.retention.ms的配置，Kafka将尝试在7天后删除日志。因此，基于该异常，Kafka希望清理文件/kafka/logs/__transaction_state-11/00000000000000807727.log，但是，Kafka日志目录中没有此类文件，并且抛出了一个异常，该异常导致代理关闭。

如果您能够关闭群集，而Zookeeper可以执行该操作并手动清理/kafka/logs/__transaction_state-11。

注意：我不知道这是否有害，但是您可以安全删除Kafka主题帖子。
