| <p><em><em>Ozone 是 Hadoop 的分布式对象存储系统，具有易扩展和冗余存储的特点。<p> |
| Ozone 不仅能存储数十亿个不同大小的对象，还支持在容器化环境（比如 Kubernetes）中运行。</em></em> <p></p> |
| <p>Apache Spark、Hive 和 YARN 等应用无需任何修改即可使用 Ozone。Ozone 提供了 <a href="../zh/interface/javaapi.html">Java API</a>、<a href="../zh/interface/s3.html">S3 接口</a>和命令行接口，极大地方便了 Ozone |
| 在不同应用场景下的使用。</p> |
| <p>Ozone 的管理由卷、桶和键组成：</p> |
| <ul> |
| <li>卷的概念和用户账号类似，只有管理员可以创建和删除卷。</li> |
| <li>桶的概念和目录类似，用户可以在自己的卷下创建任意数量的桶，每个桶可以包含任意数量的键，但是不可以包含其它的桶。</li> |
| <li>键的概念和文件类似，用户通过键来读写数据。</li> |
