有人知道如何解决这个错误吗?我读到我可以在 fileutils.setPermission 并用 checkReturnValue ,但我不知道怎么做。

我相信你正在windows上运行这个程序。我相信这里也解决了类似的问题
请在此处查看有关windows hadoop安装的一些信息

您可以使用以下解决方法来抑制此错误:
在hadoop目录下,进入src->core->org->apache->hadoop->fs
打开fileutil.java
注解掉第685行checkreturnvalue函数中的代码。
重新创建hadoop-core-1.0.4.jar并将其包含在eclipse项目的构建路径中。
这应该能解决问题。
