Major Description
The hadoop.cmd currently checked in into hadoop-common is in UNIX format, same as most of other src files. However, the hadoop.cmd is meant to be used on Windows only, the fact that it is in UNIX format makes it unrunnable as is on Window platform.
An exception shall be made on hadoop.cmd (and other cmd files for what matters) to make sure they are in DOS format, for them to be runnable as is when checked out from source repository.
