kafka在启动的时候不久，就会出现这样的问题：
引用：https://community.microstrategy.com/s/article/Kafka-could-not-be-started-due-to-Failed-to-clean-up-log-for-consumer-offsets-in-MicroStrategy-10-x?language=en_US
This is caused by a defect in Apache Kafka where the service crashes upon trying to clean up data files that have exceeded the retention policy. This crash can occur after the service has been running for some time, or on startup. The data files contain all data that has been received by the Telemetry Server (i.e. Platform Analytics Statistics and DSSErrors log contents) and by default are automatically cleaned up after 7 days. See the Apache website for more details of the Kafka issue.
人家说法是这样子的，kafka试图清理超出保留策略的数据文件，从而引起了服务崩溃。
https://issues.apache.org/jira/browse/KAFKA-7278 里面有挺多的相同问题的说明，大概看了下是kafka本身的一个问题，但是对于问题的处理，现在还是要考虑的，现在这个问题的本质是什么。
~~~~~~
已经过了一个晚上，早上看到时，又是已经关闭状态！现在仍旧是不明所以然，现在的想法是，应该慢慢的静下心来，根据日志对症下药，一个临时的处理办法是监听日志，进行响应的清理日志和重启kafka服务，但是还是治标不治本。
对于实质性的问题，这边启动的时候，查看了启动的配置：

bash下面启动kafka，在过一段时间确认下问题~~~~后面还是没有处理掉问题。
