Understand the project

Practical overview

When it fits

Consider it when a machine-learning workflow or cluster application already uses Apache Spark and needs H2O functionality within that environment.

Who it is for

  • Teams building machine-learning workflows on Apache Spark that want to incorporate H2O functionality.
  • Developers integrating H2O capabilities into existing Spark cluster applications.

Documented uses

  • Use H2O functionality in Spark-based machine-learning workflows.
  • Bring H2O capabilities into applications running with Spark clusters.
Before you choose

Requirements & limits

  • The project is infrastructure for integrating H2O with Spark, not documented here as a standalone model-serving application.
  • The repository lists Scala as its primary language and Apache-2.0 as its license.
  • The project links to documentation for Sparkling Water 3.3 latest-stable.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Choose Sparkling Water documentation and binaries for a Spark version

Locate the user documentation and binary download page for a listed Spark version.

Before you start

  • Choose a Spark version listed by the project: 2.3, 2.4, or 3.0 through 3.5.

Steps

  1. Open the Sparkling Water README.

  2. Under Getting Started, select the User Documentation link for your Spark version.

  3. Select the corresponding Download Binaries link to open that version’s binary download page.

Expected outcome

You reach the version-specific documentation and binary download page for the selected Spark version.

Guide limitations

  • The README lists versions 2.3, 2.4, and 3.0 through 3.5; it does not document installation or execution steps here.
  • The README states releases are published to Maven Central but provides no Maven coordinates in the available content.
