需要安装 hadoop 的帮助
我是 Hadoop 新手，并尝试使用 cygwin 将其安装在我的 Windows 7 (x64) PC 上。 我按照本教程安装 http://alans。 se/blog/2010/hadoop-hbase-cygwin-windows-7-x64/#software
在此步骤之前一切正常 -
Only Hadoop 0.21.0: Next, one line has to be added to the hadoop-config.sh file in hadoop-0.21.-0/bin
CLASSPATH=`cygpath -wp "$CLASSPATH"`
Add this line before the line containing
JAVA_LIBRARY_PATH=''
这行是否 正确 CLASSPATH=cygpath -wp "$CLASSPATH" 需要按原样复制吗？
因为当我尝试运行下面的命令时。
$ bin/hadoop namenode -format
我从 cygwin 收到这样的错误，
/usr/local/hadoop-0.21.0/bin/hadoop-config.sh: line 15: $'\r': command not found
/usr/local/hadoop-0.21.0/bin/hadoop-config.sh: line 19: $'\r': command not found
/usr/local/hadoop-0.21.0/bin/hadoop-config.sh: line 21: $'\r': command not found
/usr/local/hadoop-0.21.0/bin/hadoop-config.sh: line 75: syntax error near unexpected token `$'in\r''
'usr/local/hadoop-0.21.0/bin/hadoop-config.sh: line 75: `case "`uname`" in
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
HDFS not found.
谁能解释一下出了什么问题？
I am new to Hadoop and trying to install it on my windows 7 (x64) PC using cygwin.
I followed this tutorial to install http://alans.se/blog/2010/hadoop-hbase-cygwin-windows-7-x64/#software
Everything goes correct before this step -
Only Hadoop 0.21.0: Next, one line has to be added to the hadoop-config.sh file in hadoop-0.21.-0/bin
CLASSPATH=`cygpath -wp "$CLASSPATH"`
Add this line before the line containing
JAVA_LIBRARY_PATH=''
Does this line
CLASSPATH=cygpath -wp "$CLASSPATH" need to be copied as it is?
Coz when I am trying to run command below.
$ bin/hadoop namenode -format
I am getting such error from cygwin
/usr/local/hadoop-0.21.0/bin/hadoop-config.sh: line 15:

您正在使用已弃用的命令。要获取 hadoop 命令列表，请在控制台上输入 hadoop。我相信该命令是 hadoop namenode -format
you are using a deprecated command. For a list of hadoop commands, enter hadoop on your console. I believe the command is hadoop namenode -format
我使用 cygwin 1.7 也遇到了这些错误：
这些文件似乎不是 DOS CR/LF 格式，而不是预期的 UNIX 格式。
您可以使用 Notepad++ 等文本编辑器来确认这一点。在窗口的右下部分，可以显示 Dos\Windows（很可能是您会看到的内容）或 UNIX。
为了解决这些错误，在 cygwin 窗口中，我根据需要在 bin 文件夹和其他文件夹（conf 等）中使用了命令 dos2unix *.sh。
希望这对您有帮助！
I also got these errors using cygwin 1.7:
It appears that these files are not in DOS CR/LF format instead of the expected UNIX format.
You can confirm this with a text editor like Notepad++. In the lower right hand part of the window, it can say Dos\Windows (very likely what you would see) or UNIX.
To work around these errors, in a cygwin window I used the command dos2unix *.sh in the bin folder and other folders (conf, etc...) as needed.
Hope this helps you!
使用 dos2unix filename （shell 命令）将 config.sh 文件或 d 构建中所需的任何配置文件转换为 unix 格式。看来文件默认更改为 DOS 格式。最好使用 (dos2unix ./*) shell 命令将 d 文件夹中的每个文件转换为 unix。
Convert the config.sh file or any config file needed in d build to unix format with dos2unix filename (shell command). It seems the files changes to DOS format by default. Better convert every file in d folder to unix with (dos2unix ./*) shell command.
Cygwin 的错误似乎是 npm 脚本的已知错误。您可以使用此处提到的解决方法，

The error with Cygwin seems to be a known error with npm script. You can use the work around mentioned here,
