我是 Cassandra 新手,我使用 Windows 10 进行开发。但这一次 Cassandra 正在消磨我的时间。我已经阅读了文档,但仍然遇到同样的问题。
我的步骤如下:
- Windows 10 64 位。
- 已安装 Java jdk-14.0.1。
- 设置 JAVA_Home。
- 已安装 Cassandra-3.11.3
- 已安装 Python。
- 设置必要的环境变量。
- 在
PowerShell
中将当前用户的执行策略
设置为无限制
。 - 然后在
Cassandra\bin
文件夹中运行cassandra.bat
。
但它显示以下错误:
PS C:\Program Files\apache-cassandra-3.11.6\bin> .\cassandra.bat -f
检测到 powershell 执行权限。使用增强的启动脚本运行。
WARNING! 1 swap file(s) detected
Name: c:\pagefile.sys
It is recommended that you disable swap when running Cassandra
for performance and stability reasons.

最佳答案
- Installed Java jdk-14.0.1.
这是我在这里看到的最大问题。当前版本的 Cassandra 仅支持 Java 1.8,因此您需要先进行设置,然后才能运行。
关于java - Cassandra 3.11.6 无法启动 Windows 10,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/61350352/
