Hadoop Download issue

[Gary Beckler <garybeckler@xxxxxxxxx>]

When I type the command

wget http://mirror.stjschools.org/public/apache/hadoop/common/hadoop-3.0.0.tar.gz

from ubuntu linux I get the error

Connecting to mirror.stjschools.org (mirror.stjschools.org)197.84.43.531:80...connected.
HTTP request sent, awaiting response...404 Not Found
ERROR 404: Not Found

Do you know what the issue is?  I have also tried the 2.9 release as well as another mirror site and have received the same error.  Which release should I download?  This is for non-production use.

Thanks,

Gary
