Install OS X 10.10 Yosemite in VirtualBox

Due to the high usage of this guide and the lack of comfort in Gist's commenting area, I decided to make a blog post out of this which you can find here:

http://blog.frd.mn/install-os-x-10-10-yosemite-in-virtualbox/

Info

This guide sets up a non-clustered Nutch crawler, which stores its data via HBase. We will not learn how to setup Hadoop et al., but just the bare minimum to crawl and index websites on a single machine.

Terms

Nutch - the crawler (fetches and parses websites)
HBase - filesystem storage for Nutch (Hadoop component, basically)
