Hi everyone, I had a chat with some folks behind the H2O project (http://h2o.ai), and they would be interested in having H2O run on top/inside of Flink. H2O is a very performant system focused on Machine Learning.
A similar integration has been implemented for H2O on Spark (called sparkling water - https://github.com/h2oai/sparkling-water). This would be a very cool project for someone that is interested in getting started with Flink, and it should not be too hard to get started by following sparkling water as a blueprint. So if someone wants to jump on that, it would be great! Michal, the creator of sparkling water is also willing to guide/give advice.
