A timely Hadoop reality check
"And Redshift also has the analytics piece. Does that mean it’s essentially AWS’s answer to Hadoop?Talking the Cloud Business with Amazon CTO Werner Vogels | Re/code
I find that is slightly disappearing, actually. If you look at MapReduce by itself or Hadoop by itself, it’s just a distributed execution engine. You still have to write your own analytics programs, which turns out to be rather bothersome for businesses. … Among our customers like Netflix, they’re making heavy use of Elastic MapReduce. It drives their realtime operations; it drives their recommendation engine, their business dashboards. But we see quite a few other companies moving away from MapReduce and toward Redshift because you don’t need to write any analytics code anymore."
