On December 18th, we held the first of a series of Spark development meetups, for people interested in learning the Spark codebase and contributing to the project. There was quite a bit more demand than we anticipated, with over 80 people signing up and 64 attending. The first meetup was an introduction to Spark internals. Thanks to one of the attendees, there’s now a video of the meetup on YouTube. We’ve also posted the slides. Look to see more development meetups on Spark and Shark in the future.
