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-ozone/dist/target/ozone-*/ directory. Your Unix shell should expand the '*' wildcard to the correct Ozone version number.
Configuration
Save the minimal snippet to hadoop-ozone/dist/target/ozone-*/etc/hadoop/ozone-site.xml in the compiled distribution.

Start Services
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 --init
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. E.g.
| Code Block | ||||
|---|---|---|---|---|
| ||||
bin/ozone sh volume create vol1
bin/ozone sh bucket create vol1/bucket1
dd if=/dev/zero of=/tmp/myfile bs=1024 count=1
bin/ozone sh key put vol1/bucket1/key1 /tmp/myfile
bin/ozone sh key list vol1/bucket1 |
Stop Services
| Code Block | ||
|---|---|---|
| ||
bin/ozone --daemon stop om
bin/ozone --daemon stop scm
bin/ozone --daemon stop datanode |
Clean up your Dev Environment (Optional)
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}* |
