Hi, Google doesn't use Hadoop. Google published some papers on their distributed computing environment that they invented. Then some Java programmers implemented Hadoop after reading the papers published by Google. Hadoop is grossly inefficient, as it is written in Java. But it does work. Folks who use Hadoop include Yahoo. I believe Amazon uses it as well. If you care about CPU cycles, then you really don't want to get involved with Hadoop.
