Question

我正在尝试在hadoop上工作，所以我使用： -

Java 1.6 Eclipse Europa 3.3.2 安装Cygwin hadoop 0.19.1 当我使用命令时发生错误： -

$ hadoop-*/bin/hadoop namenode -format

cygwin warning:
  MS-DOS style path detected: C:\CYGWIN~1\home\user\HADOOP~1.1\/build/native
  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:

任何人都可以帮我删除此错误。谢谢

你的新行字符似乎有问题，这会阻止hadoop找到你的java二进制文件。请参阅stackoverflow上的this问题。

尝试在dos2unix上运行hadoop-env.sh。

执行hadoop namenode -format
