Ubuntu 由于sstable损坏，无法启动Cassandra

运行后：-

sudo service cassandra start

后跟

sudo service cassandra status

我得到一个无法访问cassandra的PID文件。

当我检查日志时，它给了我这个，我假设它的sstable损坏，但找不到任何方法来解决它

在ubuntu 16.04+cassandra 3.4.0上，我的解决方案是删除异常所指向的中间文件。我没有丢失任何开发数据，但我现在正在做备份。

我会假设一些事情，所以我可能错了。如果您只是安装cassandra，则需要先删除一些临时数据，然后才能运行它：

sudo rm-rf/var/lib/cassandra/data/system/*

我已尝试删除该文件夹中的文件，但仍然会遇到与您遇到的问题相同的错误。查找“CompressionInfo.db”组件大小为0的sstables并将其删除。一旦节点备份，请确保在删除sstables后运行repair，我仍然会收到相同的错误，还有一个额外的错误。还有其他的解决方法吗？我也有同样的问题，我关注博客，它解决了我的问题。
