ubuntu - 由于 sstable 损坏，无法启动 Cassandra

Question

在我运行之后:- sudo service cassandra start 然后是 sudo service cassandra status 我得到一个无法访问 Cassandra 的 pidfile。

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

我在删除 sstables 后收到了这个额外的错误。

我也意识到其他节点上的错误，但我能够启动它们。空指针异常

Answer 1

在ubuntu 16.04+cassandra 3.4.0上，我解决这个问题的方法是删除异常指向的中间文件。我没有丢失任何开发数据，但我现在正在做备份。
