Ozone is a work in progress and there is no official release. To use it, you have to build a package and deploy a cluster.

Build Ozone

  git clone git://git.apache.org/hadoop.git
  cd hadoop && git checkout trunk
  mvn clean package install -Phdds -DskipTests=true -Dmaven.javadoc.skip=true -Pdist -Dtar -DskipShade

Initial compilation may take over 30 minutes as Maven downloads dependencies. skipShade makes compilation a little faster for development and it is not required.

This will give you a tarball in your distribution directory. Here is an example of the tarball that will be generated.

hadoop-dist/target/hadoop-project-dist-3.2.0-SNAPSHOT.tar.gz

Start Cluster Using Docker

After building the package, run the following command in the git root directory.

  cd $(git rev-parse --show-toplevel)/hadoop-dist/target/ozone-?.?.?-SNAPSHOT/compose/ozone
  docker-compose up -d

For more docker-compose commands, please check the end of the Getting started with docker guide

To Shutdown the cluster, please run the command docker-compose down

Run Commands Against Ozone

To run commands on your Ozone cluster please ssh into any DataNode.

  docker-compose exec datanode bash

The Ozone command shell is documented here.

Alternatively, you can try running freon, the load generator for ozone. The following command creates a volume, ten buckets and writes one hundred keys to each bucket using corona.

  ozone freon -mode offline -validateWrites -numOfVolumes 1 -numOfBuckets 10 -numOfKeys 100

You can check the OzoneManager UI to see the activity generated by corona. The docker-compose configuration forwards port 9874 of the docker host to the OzoneManager web UI.

While you are there, please check out the ozone documentation.
