Ozone is a distributed key-value store that can efficiently manage both small and large files alike. While HDFS provides POSIX-like semantics, Ozone looks and behaves like an Object Store.

This series of articles will help you get started contributing to the Apache Hadoop Ozone project.

What is Ozone?

Ozone is a distributed key-value store designed to scale to billions of objects and run on clusters of thousands of nodes.

Ozone supports RPC and S3 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, please download a release from Ozone website.

Try it out!
