cassandra - upgradesstables 在 dse cassandra 升级中不起作用

Question

我正在将 DSE cassndra 从 4.8.16 升级到 5.0.15 ，但是当我执行nodetool upgradesstables时出现以下错误：

error: commitlog directory '/var/lib/cassandra/commitlog' or, if it does not already exist, an existing parent directory of it, is not readable and writable for the DSE. Check file system and configuration.
-- StackTrace --

以前版本的提交日志与新版本不兼容。要刷新旧安装的提交日志，请使用

nodetool -h hostname drain

还要检查 cassandra.yml 中的提交日志目录路径。
