Getting Started

In this section we'll get you started using Hazelcast Jet. First we'll show you how to set up a Java project with the proper dependencies. This will be followed by two tutorials through which you'll learn about Jet's distributed computation model, its Core API, and how to use it to create and execute batch and streaming computation jobs.

Requirements

In the good tradition of Hazelcast products, Jet is distributed as a JAR with no other dependencies. It requires JRE version 8 or higher to run.

Using Maven and Gradle

The easiest way to start using Hazelcast Jet is to add it as a dependency to your project.

Hazelcast Jet is published on the Maven repositories. Add the following lines to your pom.xml:

<dependencies>
  <dependency>
    <groupId>com.hazelcast.jet</groupId>
    <artifactId>hazelcast-jet</artifactId>
    <version>0.4</version>
  </dependency>
</dependencies>

If you prefer to use Gradle, execute the following command:

compile 'com.hazelcast.jet:hazelcast-jet:0.4'

Downloading

Alternatively you can download the latest distribution package of Hazelcast Jet and add the hazelcast-jet-<version>.jar file to your classpath.

Distribution Package

The distribution package contains the following scripts to help you get started with Hazelcast Jet:

• bin/start-jet.sh and bin/start-jet.bat start a new Jet member in the current directory.
• bin/stop-jet.sh and bin/stop-jet.bat stop the member started in the current directory.
• bin/submit-jet.sh and bin/submit-jet.bat submit a Jet computation job that was packaged in a self-contained JAR file.
• bin/cluster.sh provides basic functionality for Hazelcast cluster manager, such as changing the cluster state, shutting down the cluster or forcing the cluster to clean its persisted data.
