的解決方案是在這裏http://javaprotlib.sourceforge.net/packages/io/howtofixhadoop.html給出。我安裝了最新版本的cygwin,但我不知道如何設置環境變量,因爲我可以在該頁面上提到的cygwin-chmod中找到cygwin安裝目錄中的任何位置。如何設置該變量以及運行該程序的其他配置是什麼。

在我的C設置系統路徑變量chmod.exe 的位置,如果您已經安裝使用Windows Installer cygwin64那麼你應該chmod.exe下

INSTALLATION_DIR\cygwin64\bin 

對於我的存在,我已經安裝了Cygwin驅動器,所以我的系統路徑變量的值是;C:\cygwin64\bin
