***This is a guide on how to build the ozone sources.  If you are <font
color="red">not</font>
planning to build sources yourself, you can safely skip this page.***

If you are a Hadoop ninja, and wise in the ways of Apache,  you already know
that a real Apache release is a source release.

If you want to build from sources, Please untar the source tarball and run
the ozone build command. This instruction assumes that you have all the
dependencies to build Hadoop on your build machine. If you need instructions
on how to build Hadoop, please look at the Apache Hadoop Website.

```bash
mvn -f pom.ozone.xml clean package -DskipTests=true
```

This will build an ozone-\<version\>.tar.gz 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.

## How to test the build
You can run the acceptance tests in the hadoop-ozone directory to make sure
that  your build is functional. To launch the acceptance tests, please follow
 the instructions in the **README.md** in the `smoketest` directory. 

```bash
cd smoketest
./test.sh
```

 You can also execute only a minimal subset of the tests:

```bash
cd smoketest
./test.sh --env ozone basic
```

Acceptance tests
 will start a small ozone cluster and verify that ozone shell and ozone file
 system is fully functional.
