cygwin warning:

    Preferred POSIX equivalent is: /cygdrive/c/CYGWIN~1/home/user/HADOOP~1.1/build/native 
    CYGWIN environment variable option "nodosfilewarning" turns off this warning. 
    Consult the user's guide for more details about POSIX paths:

任何人都可以幫助我刪除此錯誤。 謝謝

看來你有一個問題，你的換行符可以防止hadoop找到你的java二進制文件。請參閱this關於stackoverflow的問題。

嘗試在hadoop-env.sh上運行dos2unix。
