At BackType, we are heavy users of Hadoop. We use it to run computations on our 30TB datastore of social data. We've even open-sourced some significant projects that are built on top of Hadoop.
Unfortunately, Hadoop has problems. It's sloppily implemented and requires all sorts of arcane knowledge to operate it. We would be the first to try out a replacement for Hadoop if a viable alternative existed. In this post, we'll look at some of the darker aspects of Hadoop.
This latest trend to devise and deploy legal strategies against open source seems to me to represent an admission on Microsoft's part that it can no longer compete on technology. Instead, the dinosaurs have decided that it's time to play really dirty – and nothing is dirtier than enforcing bad monopolies using worse laws.
