hadoop - 执行 hadoop namenode -format

Question

我正在尝试在 hadoop 上工作，因此我使用:-

Java 1.6 Eclipse 欧罗巴 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:

谁能帮我消除这个错误。 谢谢

您的换行符似乎有问题，这会阻止 hadoop 找到您的 java 二进制文件。参见 this关于 stackoverflow 的问题。

尝试在你的 hadoop-env.sh 上运行 dos2unix。
