# Apache Hadoop Ozone
|
|
|
|

|
|
*_Ozone is a scalable, redundant, and distributed object store for Hadoop. <p>
|
|
Apart from scaling to billions of objects of varying sizes,
|
|
Ozone can function effectively in containerized environments
|
|
like Kubernetes._* <p>
|
|
|
|
Applications like Apache Spark, Hive and YARN, work without any modifications when using Ozone. Ozone comes with a [Java client library]({{<
|
|
ref "JavaApi.md"
|
|
>}}), [S3 protocol support] ({{< ref "S3.md" >}}), and a [command line interface]
|
|
({{< ref "shell/_index.md" >}}) which makes it easy to use Ozone.
|
|
|
|
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.
