Thanks @rich7420 for working on this. I have a few concerns:

1. This Dockerfile is mostly unused. Ozone's Docker image is in a separate repository: https://github.com/apache/ozone-docker I'll file a task to remove it and related parts of the POM.
2. We should create alternative "slim" image, not strip content from existing image.
3. Deleting files in a RUN step does not reduce size grown in previous steps (ADD in this case), because images are layered.

oh ok, understood. I'll close this one and open a PR in ozone-docker repo.
