java - 独立启动 cassandra 失败，出现 FSWriteError

Question

我正在按照 Cassandra 网站上的独立服务器 v2.1.1 教程进行操作。我试图让它在流浪实例上运行。 JDK 版本是 java 版本“1.7.0_72”。即使当我使用 sudo bin/cassandra -f 启动 Cassandra 时，我也会收到此错误:

DEBUG 22:14:34 Creating new commit log segment /vagrant/apache-cassandra-2.1.1/out/commitlog/CommitLog-4-1415657674222.log

CommitLog 文件已创建，但服务器仍处于停止状态。

我该怎么做才能让 cassandra 运行起来？

Answer 1

/vagrant 目录是与主机共享的文件系统 (Mac OSX 10.10)。提交日志被写入此文件系统的一个目录中。

当我将 conf/cassandra.yaml 中的变量 commitlog_directory 设置为不在/vagrant 共享驱动器上的目录时，我能够启动 Cassandra。
