HDFS-7240 and build it.

git checkout HDFS-7240 mvn clean package -DskipTests=true -Dmaven.javadoc.skip=true -Pdist -Dtar -DskipShade |
Note: *skipShade* is just to make compilation faster and not really required.
This will give you a directory tarball in your distribution directory. Here is an example of the tarball that will be generated.
* `~/apache/hadoop/hadoop-dist/target directory which could be mapped to the docker containers.

/hadoop-project-dist-3.1.0-SNAPSHOT.tar.gz`
At this point, we have an option to set up a physical cluster or run ozone via docker.
