Fraud — absolutely.

Apps on which other technologies do a really great job — not so much.

It would be interesting to comment on real world use cases for Hadoop/MR for enterprise *structured* data. Google, Facebook and Yahoo have unique data requirements, but that’s 3 super high volume sites. OK so Hadoop is great for them. What about everyone else.

Are folks using it for call center monitoring? Sales territory assignment? Incentive comp calculations? Mapping journal lines to sub-ledgers? Fraud detection? Time-phased correlations?

If the answer is well, no, then why is it reasonable for database vendors to invest so much dev and mktg resources into such an extremely niche technology.

I didn’t realize NZ, Tera and SenSage were doing MR as well. I really look forward to your webinars.

This is an area in which information/education channels has been lacking IMHO. Yes there’s been plenty of online material and papers on it but no centalized/big picture view that common mortal can wrap their heads around.

That’s one of the reasons I wanted to address it in my latest blog post, from a much higher altitude than I’m sure you will.

Thanks for bringing this forward in digestable ways!
