sstableloader-无法将C库与JNA链接 [英] sstableloader - Failed to link the C library against JNA

问题描述

在这里，我正在尝试还原密钥空间.而且我收到以下错误.

Here i'm trying to restore the keyspace. And i get the following error.

我在/etc/cassandra/conf/cassandra-env.sh中正确设置了JVM_OPTS ="$ JVM_OPTS -Djna.tmpdir =/var/lib/cassandra/tmp"，并将cassandra放在没有问题的位置.

I correctly set JVM_OPTS="$JVM_OPTS -Djna.tmpdir=/var/lib/cassandra/tmp" in /etc/cassandra/conf/cassandra-env.sh, and strated cassandra without issue.

但是我仍然会收到此错误.

But i still get this error.

推荐答案

我发现我需要导出JNA.

I found it i need to export JNA.

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