java - 在 Cassandra 中使用 sstabledump 时 /tmp 挂载为 noexec 时出现 java.lang.UnsatisfiedLinkError

问题描述

我收到以下错误

我jna.tmpdir=/data/cassandra/tmp根据我在 stacker 中找到的一些帖子添加了，但它仍然出现相同的错误。有什么建议吗？

解决方案

在 bash 配置文件中创建一个条目>>>

 export JVM_OPTS="$JVM_OPTS -Djna.tmpdir=/var/lib/cassandra/tmp"

然后为立即生效，请执行以下 source 命令：

source ~/.bash_profile

还请在“var/lib/cassandra/”中创建一个具有用户访问/所有权的目录“tmp”。

上述解决方案对我有用。
