cassandra-2.0 - Cassandra 2.2.1 不会启动使用 cassandra -f

Question

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 命令提示符下键入:cassandra -f，这就是我得到的结果:

E:\apache-cassandra-2.2.1\bin>cassandra -f

E:\apache-cassandra-2.2.1\bin>

这让我抓狂。我不明白为什么这这么难。

我在 Windows 10 专业版上运行并且有足够的空间。这是在笔记本电脑上运行的，应该可以运行，但当然不行。

我的 cassandra.yaml 文件没问题。

我正在运行 localhost 作为我的“种子”。我应该将其设置为 127.0.0.1、localhost 还是我本地机器的 IP？

我需要调整我的“etc/hosts”文件吗？

任何人都将不胜感激。

Answer 1

1. 在:C:\Program Files\apache-cassandra-3.11.3\conf"文件夹中，打开文件 - "cassandra-env。
2. 搜索:JAVA_HOME
3. 它将向您显示由 java exe 文件的代码创建的路径。
4. 仔细检查并确保路径正确。

您可以通过直接更新文件或按照其他答案中的说明更新环境变量来完成此操作。
