【问题描述】：
我已经从 apache.cassandra 下载了 cassandra。
我已确保我的 env 路径变量设置正确。
我在 Windows 命令提示符中键入：cassandra -f，这就是我得到的：
E:\apache-cassandra-2.2.1\bin>cassandra -f

这让我发疯了。我不明白为什么这么难。
我在 Windows 10 pro 上运行并且有足够的空间。这是在笔记本电脑上，应该可以，但当然不是。
我的 cassandra.yaml 文件很好。
我正在运行 localhost 作为我的“种子”。我应该将其设为 127.0.0.1、localhost 还是仅设为本地机器的 IP？
我需要调整我的“etc/hosts”文件吗？
任何能提供帮助的人都将不胜感激。
