From Source

Requirements
  • x86 or ARM64
  • Linux or MacOS
  • JDK 1.8 or higher
  • Maven 3.6 or later
  • Internet connection for first build (to fetch all Maven and Ozone dependencies)

You will also need to install the following dependencies to build native code (optional):

  • gcc
  • cmake

If you want to build from sources, Please untar the source tarball (or clone the latest code from the git repository).

ARM-based Linux

If you are using an ARM-based Linux, patch protobuf 2.5.0 and build it from source.

sudo yum install -y make cmake gcc g++ patch
# or for Ubuntu and Debian:
# sudo apt-get install -y make cmake gcc g++ patch

# Download protobuf 2.5.0 tarball
curl -sSL https://github.com/protocolbuffers/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.gz | tar zx

Build Ozone

Run the ozone build command.

mvn clean package -DskipTests=true

This will build an ozone-\<version\> directory in your hadoop-ozone/dist/target directory.

You can copy this tarball and use this instead of binary artifacts that are provided along with the official release.

Depending on the network speed, the build can take anywhere from 10 minutes to 20 minutes.

To create tarball file distribution, use the -Pdist profile:

mvn clean package -DskipTests=true -Pdist

Other useful Maven build options

  • Use -DskipShade to skip shaded Ozone FS jar file creation. Saves time, but you can’t test integration with other software that uses Ozone as a Hadoop-compatible file system.
  • Use -DskipRecon to skip building Recon Web UI. It saves about 2 minutes.
  • Use -Dmaven.javadoc.skip=true to skip building javadocs.
  • Use -Drocks_tools_native to build the RocksDB native code for the Ozone Snapshot feature. This is optional and not required for building Ozone. It is only needed if you want to build the RocksDB native code for Ozone.

How to run Ozone from build

When you have the new distribution, you can start a local cluster with docker-compose.

cd hadoop-ozone/dist/target/ozone-X.X.X...
cd compose/ozone
docker-compose up -d

How to test the build

compose subfolder contains multiple type of example setup (secure, non-secure, HA, Yarn). They can be tested with the help of robotframework with executing test.sh in any of the directories.
