start-ozone environment

This is an example environment to use/test ./sbin/start-ozone.sh and ./sbin/stop-ozone.sh scripts.

There are ssh connections between the containers and the start/stop scripts could handle the start/stop process similar to a real cluster.

To use it, first start the cluster:

docker-copmose up -d

After a successfull startup (which starts only the ssh daemons) you can start ozone:

./start.sh

Check it the java processes are started:

./ps.sh
