Question

我将DSE cassndra从4.8.16升级到5.0.15，但是当我执行nodetool upgradesstables时，我得到了以下错误：

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 --

Answer 1

我遇到了问题，我的安装目录和软件包目录不同。我从软件包目录运行命令，这就是为什么它选择错误路径的原因。为了解决这个问题，我将属性“ CASSANDRA_CONF”设置为正确的路径，从而解决了该问题。

Answer 2

提交与新版本不兼容的先前版本的日志。要刷新旧安装的提交日志，请使用

nodetool -h hostname drain

还要在cassandra.yml中检查提交日志目录路径。

升级表在DSE Cassandra升级中不起作用
