THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
This is the traditional method. Please follow the build instructions first (see Build Ozone).

Once the package is built, you can start Ozone services by going to the hadoop-dist/target/ozone-0.?.?-SNAPSHOT directory. Your Unix shell will expand the '?.?.?' wildcard to the correct Ozone version number.
Configuration
Save the minimal snippet to hadoop-dist/target/ozone-?.?.?-SNAPSHOT/etc/hadoop/ozone-site.xml in the compiled distribution.

Run
To start ozone, you need to start SCM, OzoneManager and DataNode. In pseudo-cluster mode, all services will be started on localhost.
| Code Block | ||

bin/ozone scm -init
bin/ozone --daemon start scm
bin/ozone om -createObjectStore
bin/ozone --daemon start om
bin/ozone --daemon start datanode |
Run Ozone Commands
Once you have ozone running you can use these Ozone shell commands to create a volume, bucket and keys.
Clean up your Dev Environment
Remove the following directories to wipe the Ozone pseudo-cluster state. This will also delete all user data (volumes/buckets/keys) you added to the pseudo-cluster.
| Code Block |
|---|
rm -fr /tmp/ozone
rm -fr /tmp/hadoop-${USER}* |
