Question

cassandra 3.6

openjdk version“1.8.0_91”

当我启动cassandra服务时会抛出此错误。

这意味着什么，我该怎么做才能解决这个问题。

最后我得到了答案。

系统文件已损坏且出现问题。

所以你需要删除里面的所有目录＆＃34; / var / lib / cassandra / data /＆＃34;除了你的密钥空间。

*注意：不要删除密钥空间数据。

cassandra无法对/ var / lib / cassandra / data / system_schema / columns-24101c25a2ae3af787c1b40ee1aca33中的文件进行分类
