Big Data Cartoon - What is text analytics?

Analytics may be the next big thing in Big Data, but it is very hard to define what it really is. Firstly, this word shows as misspelled in the browser and in Word or OpenOffice. Secondly, it's too vague and nebulous. As always, when in doubt, we turn to our illustrator, and our RK can illuminate us with a simple to understand cartoon that even data scientists can get.

Big Data Cartoon - What's the latest and greatest in Hadoop?

What's the latest and greatest in Hadoop? Ask this question, and many people will say "Real-time" and point to Spark. Look at Berkeley's AMP labs two-day seminar going on right now, for example.

But what is Spark, really? What are those RDD's? They stand for Resilient Distributed Datasets, but is it any clearer? We asked our illustrator to clarify this, and hopefully we got it explained.
