Build From Git Repo

Get the Apache Hadoop Ozone source code from the Apache Git repository. Then check out trunk and build it with the the hdds Maven profile enabled.

  git clone https://gitboxgithub.com/apache.org/repos/asf/hadoop/ozone.git
  cd hadoop-ozone
  mvn clean install -Phdds -DskipTests=true -Dmaven.javadoc.skip=true -Pdist -Dtar -DskipShade

...

Download and extract a source tarball from https://hadoopozone.apache.org/ozone/downloads/ E.g.

  tar xf hadoop-ozone-01.32.0-alpha1-src.tar.gz
  cd hadoop-ozone-01.32.01-alpha-src-with-hdds/
  mvn clean install -Phdds -DskipTests=true -Dmaven.javadoc.skip=true -Pdist -Dtar -DskipShade

Partial build

Ozone requires just a subset of the hadoop submodules (for example hdfs/common projects are needed but mapreduce/yarn projects are not). The build could be make faster with building just the ozone-dist project (-pl :hadoop-ozone-dist) and all of the dependencies (-am)

  mvn clean install -Phdds -DskipTests=true -Dmaven.javadoc.skip=true -Pdist -Dtar -DskipShade -am -pl :hadoop-ozone-dist

Download Binary Release

Download and extract a binary release from https://hadoopozone.apache.org/ozone/downloads/ E.g.

  tar xf hadoop-ozone-01.32.0-alpha1.tar.gz
  cd hadoop-ozone-01.32.0-alpha1/

Start Cluster Using Docker

If you downloaded or and built a source release, run to start the docker cluster using the package you built, please add "-Ddocker.ozone-runner.version=dev" to the maven build command line.  Run the following commands to start an Ozone cluster in docker containers with 3 datanodes.

Replace SCM-HOSTNAME and OM-HOSTNAME with the names of the machines where you want to start the SCM and OM services respectively. It is okay to start these services on the same host. If you are unsure then just use any machine from your cluster.

ozone-env.sh

The only mandatory setting in hadoopozone-env.sh is JAVA_HOME. E.g.

...

bin/ozone om --createObjectStoreinit
bin/ozone --daemon start om
