H2O Sparkling Water Integration

1 post · Jun 2026

What this trail covers

H2O Sparkling Water integrates H2O's machine learning algorithms with Apache Spark, enabling users to perform Spark SQL queries, build models with H2O, and use the results within Spark. It supports computation from Scala, R, and Python, and allows for easy deployment of H2O models (POJOs/MOJOs) for scoring. The system runs as a regular Spark application, initializing H2O services on Spark and accessing data from both Spark and H2O data structures. It offers advanced machine learning for Spark and integrates with cloud platforms like Azure, AWS, and Google Cloud.
