Question

我无法弄清问题是什么，我已经检查了问题的所有可用链接并尝试但仍然存在同样的问题。
请提供帮助，因为可用的沙箱需要更高的配置，例如更多RAM。

此错误通常意味着您无法设置无密码SSH。例如，ssh localhost应该发生同样的错误，它不应该提示输入密码

在生成SSH密钥时再次检查Hadoop文档，并将其添加到授权密钥文件

如果沙箱需要太多资源，我可能会建议设置虚拟机（例如，使用Vagrant）。 Hortonworks＆amp; Cloudrea安装文档非常详细，可以从头开始安装集群通过这种方式，Hadoop不会使Mac的硬盘变得混乱，Linux服务器将更接近于在生产环境中运行的Hadoop安装

不在本地计算机上启动的Hadoop独立模式存在权限问题
