Ozone and Hadoop Distributed Data Store

Hadoop Distributed Data Store (HDDS) is a distributed, replicated block layer.

Ozone is a distributed key-value store built using HDDS. Ozone supports RPC and REST APIs as well as a Hadoop Compatible File System called OzoneFS.

Ozone is a work in progress and currently in alpha state. To try it out, you need to build it from the source code.

Getting started

You have multiple options to run an Ozone cluster:

1. Use prebaked docker images from the docker hub (no build is required, but these images are not from the Apache Hadoop project)

2. Build a new Ozone cluster from the source code and start a cluster with docker (also useful for development)
3. Build new Ozone cluster from the source code and start it with the startup scripts without docker.

Additional information

• To follow the progress of Ozone development you can check the JIRA dashboard

• A detailed discussion of Ozone file system and design docs can be found here. 
• A detailed and work items for the security of  Hadoop Distributed Storage Layer is tracked in this JIRA

• The documentation is part of the source code, but you can check out directly from github: https://github.com/apache/hadoop/tree/trunk/hadoop-ozone/docs/content See the markdown files with Ozone prefix (Or you can generate a new site from the feature branch)
