After posting Impressions About Hive, Pig, Scalding, Scoobi, Scrunch, Spark , I've found myself wondering why so many of these libraries are built in Scala and what's their main purpose. A day later and I've found Age Mooij 's presentation about Scoobi and Scalding which provide an answer to my question. Plus a quick intro to Scoobi 1 and Scalding 2 . Check the slides after the break.
