Apache Livy

Build Status

Apache Livy is an open source REST interface for interacting with Apache Spark from anywhere. It supports executing snippets of code or programs in a Spark context that runs locally or in Apache Hadoop YARN.

Pull requests are welcomed! But before you begin, please check out the Contributing section on the Community page of our website.

Online Documentation

Guides and documentation on getting started using Livy, example code snippets, and Livy API documentation can be found at livy.incubator.apache.org.

Before Building Livy

To build Livy, you will need:

Debian/Ubuntu:

Redhat/CentOS:

MacOS:

Required python packages for building Livy:

To run Livy, you will also need a Spark installation. You can get Spark releases at https://spark.apache.org/downloads.html.

Livy requires Spark 2.4+. You can switch to a different version of Spark by setting the SPARK_HOME environment variable in the Livy server process, without needing to rebuild Livy.

Building Livy

Livy is built using Apache Maven. To check out and build Livy, run:

git clone https://github.com/apache/incubator-livy.git
cd incubator-livy
mvn package

You can also use the provided Dockerfile:

git clone https://github.com/apache/incubator-livy.git
cd incubator-livy
docker build -t livy-ci dev/docker/livy-dev-base/
docker run --rm -it -v $(pwd):/workspace -v $HOME/.m2:/root/.m2 livy-ci mvn package

Note: The docker run command maps the maven repository to your host machine's maven cache so subsequent runs will not need to download dependencies.

By default Livy is built against Apache Spark 2.4.5, but the version of Spark used when running Livy does not need to match the version used to build Livy. Livy internally handles the differences between different Spark versions.

The Livy package itself does not contain a Spark distribution. It will work with any supported version of Spark without needing to rebuild.
