i am on windows-64 bit hp machne.
i installed first latest cygwin(from local directory) to run hadoop on windows,but forgot to install tcp_wrappers pacakge.
so i deleted everything in C drive related to cygwin,also .ssh folder & .bashrc.profile
& installed again cygwin freshly.

i follow this tutorial:-http://v-lad.org/Tutorials/Hadoop/00%20-%20Intro.html
& run below command (u can see this commands in snapshot)
