This post has been published on the Cloudera blog and summurises the results and takeaways of a week-long hackathon happened in Lanzarote in December 2015. The goal was to prototype a recommender systems for retail customers of shops in Bristol in Bristol, UK. The article shows how the stack composed by Scala and Spark was great for quickly writing some prototyping code to run locally in a single laptop and at the same time scalable for larger dataset to process in the cluster.
