From Hive to Spark, How Bizo made the Jump

If you’re currently using Hive and thinking about what Spark might offer this talk is for you. At Bizo, we wrote all of our cluster computing jobs in Hive for several years. We think Hive is great, but it comes with some less than pleasant tradeoffs. A year ago we tried Spark; the ability to write normal Scala code has made unit testing and custom functions a breeze, but it’s also not perfect. This talk will cover how we transitioned from Hive to Spark, including our best practices and some painful lessons learned along the way so you don’t have to repeat the same mistakes.
