Ozone is a scalable, redundant, and distributed object store for Hadoop.
Ozone是一个可扩展的,冗余的,分布式的对象存储组件,它是Hadoop生态系统中的一员。
Apart from scaling to billions of objects of varying sizes, Ozone can function effectively in containerized environments like Kubernetes.
除了可以扩展到数十亿大小不同的数据文件存储之外,Ozone还可以有效地在容器环境中发挥作用,比如像Kubernetes等。
Applications like Apache Spark, Hive and YARN, work without any modifications when using Ozone. Ozone comes with a Java client library, S3 protocol support, and a command line interface which makes it easy to use Ozone.
像Spark、Hive和Yarn等应用,可以直接运行在Ozone之上,不需要进行任何修改。Ozone自带有Java客户端和命令行接口以及对S3协议的支持,这使得它非常易于使用。其中的Java客户端同时支持RPC协议和REST协议。
Ozone consists of volumes, buckets, and Keys.
Ozone具体由Volumes(卷)、buckets(桶)和Keys(键)组成。
-
Volumes are similar to user accounts. Only administrators can create or delete volumes.
-
Volumes(卷)类似于用户帐户,只有管理员可以创建或者删除Volumes(卷)。
-
Buckets are similar to directories. A bucket can contain any number of keys, but buckets cannot contain other buckets.
-
Buckets(桶)类似于目录,单个桶可以包含任意数量的Keys(键),但是Buckets(桶)不能包含其他Buckets(桶)。
-
Keys are similar to files. A bucket can contain any number of keys.
-
Keys(键)类似于文件,Buckets(桶)可以包含很多的Keys(键)。
