Apache Ozone === Ozone is a scalable, redundant, and distributed object store for Hadoop and Cloud-native environments. Apart from scaling to billions of objects of varying sizes, Ozone can function effectively in containerized environments such as Kubernetes and YARN. • MULTI-PROTOCOL SUPPORT: Ozone supports different protocols like S3 and Hadoop File System APIs. • SCALABLE: Ozone is designed to scale to tens of billions of files and blocks and, in the future, even more. • CONSISTENT: Ozone is a strongly consistent object store. This consistency is achieved by using protocols like RAFT. • CLOUD-NATIVE: Ozone is designed to work well in containerized environments like YARN and Kubernetes. • SECURE: Ozone integrates with Kerberos infrastructure for authentication, supports native ACLs and integrates with Ranger for access control and supports TDE and on-wire encryption. • HIGHLY AVAILABLE: Ozone is a fully replicated system that is designed to survive multiple failures.

Quick start Run Ozone with Docker Compose The easiest way to start a cluster with docker is by using Docker Compose: • Obtain Ozone’s sample Docker Compose configuration: • Start the cluster • Note: By default, the cluster will be started with replication factor set to 1. It can be changed by setting the environment variable to the desired value. And you can use AWS S3 cli: • First, let’s configure AWS access key and secret key. Because the cluster is not secured, you can use any arbitrary access key and secret key. For example: • Then we can create a bucket and upload a file to it: Run Ozone from released artifact If you need a more realistic cluster, you can download the latest (binary) release package, and start a cluster with the help of docker-compose: After you untar the binary: The folder contains different sets of configured clusters (secure, HA, mapreduce example), you can check the various subfolders for more examples. Run on Kubernetes Ozone is a first class citizen of the Cloud-Native environments. The binary package contains multiple sets of K8s resource files to show how it can be deployed. Build from source Ozone can be built with Apache Maven: And can be started with the help of Docker: For more information, you can check the Contribution guideline Contribute All contributions are welcome.
