What is new in Sparkling Water 2.0.3 Release?

This release has H2O core – 3.10.1.2

Important Feature:

This architectural change allows to connect to existing h2o cluster from sparkling water. This has a benefit that we are no longer affected by Spark killing it’s executors thus we should have more stable solution in environment with lots of h2o/spark node. We are working on article on how to use this very important feature in Sparkling Water 2.0.3.
