hadoop - hadoop中Namenode格式错误

Question

我已经安装了 hadoop，基于 cygwin 和 windows。我已按照网站上的步骤操作:http://ebiquity.umbc.edu/Tutorials/Hadoop/12%20-%20format%20the%20namendoe.html .但坚持格式化namendoe。

这给我以下错误:

请帮助我。

Answer 1

无论如何，我终于找到了解决方案，cygwin 的配置是基于 DOS 命令提示符的，因此它不接受用户名中的空格。在我的案例中，名称“Satheesh Kumar”之间的空格不接受。所以我创建了一个新的用户帐户并再次尝试并最终被执行。
