# Apache Hadoop Ozone
|
|
|
|
Ozone is a scalable, distributed object store for Hadoop. Applications like
|
|
Apache Spark, Hive and YARN, can run against Ozone without any
|
|
modifications. Ozone comes with a [Java client library]({{< ref "JavaApi.md"
|
|
>}}) and a [command line interface] ({{< ref "CommandShell.md#shell" >}}) which makes it easy to use Ozone. This client library supports both RPC and REST protocols.
|
|
|
|
Ozone consists of volumes, buckets, and Keys.
|
|
|
|
* Volumes are similar to user accounts. Only administrators can create or delete volumes.
|
|
* Buckets are similar to directories. A bucket can contain any number of keys, but buckets cannot contain other buckets.
|
|
* Keys are similar to files. A bucket can contain any number of keys.
