Recently I've noticed following article about Hadoop - HadoopVsGridGain. And to my understanding it's just an adv :) Or a kind of because only those one who is scared will put things like this on official site. I think competitors must be polite and compete instead of comparing.

I agree, GridGain and Hadoop are very different. That is why I spent time comparing them.
10,000 cores and petabytes aren't just random numbers. They are the scale that Hadoop is currently used in production.
http://developer.yahoo.com/blogs/hadoop/2008/02/yahoo-worlds-largest-production-hadoop.html
And trust me, no tool scales to that level without a lot of work testing at that scale.
All of the comparisons that had been done previously, used very difficult to understand terminology that is specific to GridGain. So, I wanted to specifically look at the map/reduce implementation in each.
GridGain may have other features that are very useful, but it isn't a useful implementation of map/reduce for anything but toy examples. The fact that there is a single reduce and that all of the map outputs have to fit in memory make it a non-starter for almost all of the applications we use map/reduce for.
