Ozone is a multi-protocol file system. There are different protocols by which users can access data on Ozone.
Ozone ships with its own client library that supports RPC. For generic use cases the S3 compatible REST interface also can be used instead of the Ozone client. Creating an Ozone client The Ozone client factory creates the ozone client. To get a RPC client we can call OzoneClient ozClient = OzoneClientFactory.getRpcClient(); If the user want to create a client based on the configuration, then they can call. OzoneClient ozClient = OzoneClientFactory.

All the files and directories will be stored as keys in this bucket.
Ozone File SystemOzone provides S3 compatible REST interface to use the object store data with any S3 compatible tools. Getting started S3 Gateway is a separated component which provides the S3 compatible APIs. It should be started additional to the regular Ozone components. You can start a docker based cluster, including the S3 gateway from the release package. Go to the compose/ozones3 directory, and start the server: docker-compose up -d You can access the S3 gateway at http://localhost:9878
