Cygwin ssh-host-config on windows for hadoop

Question

I'm new to cygwin and hadoop, please anyone could explain

• which mirror link is the proper to install cygwin
• what version of hadoop is bug free ( .sh works good )

• is it must to run below commands before running ssh-host-config

  • $ chmod +r /etc/passwd
  • $ chmod u+w /etc/passwd
  • $ chmod +r /etc/group
  • $ chmod u+w /etc/group
  • $ chmod 755 /var
  • $ touch /var/log/sshd.log
  • $ chmod 664 /var/log/sshd.log

  or http://www.kgx.net.nz/2010/03/cygwin-sshd-and-windows-7/

• for ssh-host-config what all options should i give yes and no for running sshd service and hadoop proper

• "Please enter the password for user 'cyg_server'? " if i do configuration does it necessary to login with cyg_server user id, else for running hadoop all.sh asking for password and the given password is not accepting too.
• once i tried to connect, I could do till all process to run, tried to connect through Eclipse, but it shows connection failed to localhost.

Till now I was going through different tutorials, if cygwin part goes fine then will get issue with hadoop, else get stuck with cygwin itself.

If any one could guide right way, will be helpful and even could give suggestions.
