Hadoop 0.20.2 with eclipse in windows

Hi all,

 I have been working with Hadoop0.20.2 in linux nodes. Now I want to try the
same version with eclipse on a windows xp machine. Could someone provide a
tutorial/guidelines on how to install this setup.

thanks,
Matthew

This is because you probably edited the hadoop related files (conf or
scripts) with a Windows-specific editor, like Notepad/Wordpad (which
adds /n/r newlines instead of /n which is accepted in UNIX-like
environments -- some editors do worse, but hopefully that's not the
case yet).

Open all edited files with Vim, set the newline mode to UNIX and save
it. This error should go away then. (Or any other editor/command that
changes the newline format of a file -- a linux coreutil called
dos2unix does this for you, if installed in cygwin)

I tried installing using this link, but as in the tutorial when I try to run
bin/hadoop namenode -format
it gives the following error :

bin/hadoop: line 2 : $'\r' : command not found
and many such statements..

I ve given the local jdk folder as the java_home.
Not sure why this is showing up. Ve not used Cygwin till now..

Windows + the Plugin w/ Cygwin:
