This can be alot less stress. That is a good idea.

> We should generate a big file (1-5gb?) for PageRank example. We wanted to add this as
a part of the contrib, but we skipped/lost it somehow.
> I started crawling several pages, starting from google news. But then my free Amazon
EC2 qouta expired and had to stop the crawl.
> > We need some cloud to crawl
> > We need a place to make the data available
> The stuff we need is already coded here: 
> http://code.google.com/p/hama-shortest-paths/source/browse/#svn%2Ftrunk%2Fhama-gsoc%2Fsrc%2Fde%2Fjungblut%2Fcrawl
> Afterwards a m/r processing job in the subpackage "processing" has to be run on the output
of the crawler. This job takes care that the adjacency matrix is valid.
