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.
