Java 在单机版中启动cassandra失败，错误为FSWriteError

我将在Cassandra的独立服务器v2.1.1站点上学习教程。我正试图让它在一个流浪者的实例上运行。JDK版本是java版本“1.7.0_72”。即使我用sudo bin/Cassandra-f启动Cassandra，我也会遇到以下错误：

CommitLog文件已创建，但服务器仍处于停止状态

如何让cassandra运行？

目录是与主机（Mac OSX 10.10）共享的文件系统。提交日志被写入该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。

这是Virtualbox上一个长期存在的错误。这是内存映射文件的问题；共享文件系统不支持它们

thx！后来我转到了一个不同的开发环境，但很高兴知道这一点。
