$HOME/Downloads is probably not /home/user/Downloads ,
but /home/<user-name>/Downloads/ , like : /home/tahani/Downloads/
And : root is for administrative tasks only.
It is not recommended to work as root, unless absolute necessary.
And : The default build directory is e.g. /home/tahani/tmp/
Building in /home/tahani/tmp/, the commands would be :
1) cd tmp/
2) tar xvf ../Downloads/hadoop-1.0.3.tar.gz
