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.
