+Apache Flink 使用文件系统来消耗和持久化地存储数据，以处理应用结果以及容错与恢复。以下是一些最常用的文件系统：*本地存储*，*hadoop-compatible*，*Amazon S3*，*MapR FS*，*OpenStack Swift FS*，*阿里云 OSS* 和 *Azure Blob Storage*。
-The file system used for a particular file is determined by its URI scheme.
-For example, `file:///home/user/text.txt` refers to a file in the local file system, while `hdfs://namenode:50010/data/user/text.txt` is a file in a specific HDFS cluster.
+文件使用的文件系统通过其 URI Scheme 指定。例如 `file:///home/user/text.txt` 表示一个在本地文件系统中的文件，`hdfs://namenode:50010/data/user/text.txt` 表示一个在指定 HDFS 集群中的文件。
-File system instances are instantiated once per process and then cached/pooled, to avoid configuration overhead per stream creation and to enforce certain constraints, such as connection/stream limits.

-It can be used by default without additional configuration. Local files are referenced with the *file://* URI scheme.

-The Apache Flink project supports the following file systems:
+Apache Flink 支持下列文件系统：
+ - [**Amazon S3**](./s3.html) 对象存储由 `flink-s3-fs-presto` 和 `flink-s3-fs-hadoop` 两种替代实现提供支持。这两种实现都是独立的，没有依赖项。
- - [**Amazon S3**](./s3.html) object storage is supported by two alternative implementations: `flink-s3-fs-presto` and `flink-s3-fs-hadoop`.
- Both implementations are self-contained with no dependency footprint.
+ - **MapR FS** 文件系统适配器已在 Flink 的主发行版中通过 *maprfs://* URI Scheme 支持。MapR 库需要在 classpath 中指定（例如在 `lib` 目录中）。
- - **MapR FS** file system adapter is already supported in the main Flink distribution under the *maprfs://* URI scheme.
- You must provide the MapR libraries in the classpath (for example in `lib` directory).
+ - **OpenStack Swift FS** 由 `flink-swift-fs-hadoop` 支持，并通过 *swift://* URI scheme 使用。该实现基于 [Hadoop Project](https://hadoop.apache.org/)，但其是独立的，没有依赖项。
+ 将 Flink 作为库使用时，使用该文件系统需要添加相应的 Maven 依赖项（`org.apache.flink:flink-swift-fs-hadoop:{{ site.version }}`）。
- - **OpenStack Swift FS** is supported by `flink-swift-fs-hadoop` and registered under the *swift://* URI scheme.
- The implementation is based on the [Hadoop Project](https://hadoop.apache.org/) but is self-contained with no dependency footprint.
- To use it when using Flink as a library, add the respective maven dependency (`org.apache.flink:flink-swift-fs-hadoop:{{ site.version }}`).
-
- - **[Aliyun Object Storage Service](./oss.html)** is supported by `flink-oss-fs-hadoop` and registered under the *oss://* URI scheme.
- The implementation is based on the [Hadoop Project](https://hadoop.apache.org/) but is self-contained with no dependency footprint.
+ - **[阿里云对象存储](./oss.html)**由 `flink-oss-fs-hadoop` 支持，并通过 *oss://* URI scheme 使用。该实现基于 [Hadoop Project](https://hadoop.apache.org/)，但其是独立的，没有依赖项。
- - **[Azure Blob Storage](./azure.html)** is supported by `flink-azure-fs-hadoop` and registered under the *wasb(s)://* URI schemes.
- The implementation is based on the [Hadoop Project](https://hadoop.apache.org/) but is self-contained with no dependency footprint.

-Except **MapR FS**, you can and should use any of them as [plugins](../plugins.html).
+除 **MapR FS** 之外，上述文件系统可以并且需要作为[插件](../plugins.html)使用。
-To use a pluggable file systems, copy the corresponding JAR file from the `opt` directory to a directory under `plugins` directory
-of your Flink distribution before starting Flink, e.g.
+使用外部文件系统时，在启动 Flink 之前需将对应的 JAR 文件从 `opt` 目录复制到 Flink 发行版 `plugin` 目录下的某一文件夹中，例如：
{% highlight bash %}
mkdir ./plugins/s3-fs-hadoop
cp ./opt/flink-s3-fs-hadoop-{{ site.version }}.jar ./plugins/s3-fs-hadoop/
{% endhighlight %}
-<span class="label label-danger">Attention</span> The [plugin](../plugins.html) mechanism for file systems was introduced in Flink version `1.9` to
-support dedicated Java class loaders per plugin and to move away from the class shading mechanism.
-You can still use the provided file systems (or your own implementations) via the old mechanism by copying the corresponding
-JAR file into `lib` directory. However, **since 1.10, s3 plugins must be loaded through the plugin mechanism**; the old
-way no longer works as these plugins are not shaded anymore (or more specifically the classes are not relocated since 1.10).
+<span class="label label-danger">注意</span> 文件系统的[插件](../plugins.html)机制在 Flink 版本 1.9 中引入，以支持每个插件专有 Java 类加载器，并避免类隐藏机制。您仍然可以通过旧机制使用文件系统，即将对应的 JAR 文件复制到 `lib` 目录中，或使用您自己的实现方式，但是从版本 1.10 开始，**S3 插件必须通过插件机制加载**，因为这些插件不再被隐藏（版本 1.10 之后类不再被重定位），旧机制不再可用。
-It's encouraged to use the [plugins](../plugins.html)-based loading mechanism for file systems that support it. Loading file systems components from the `lib`
-directory will not supported in future Flink versions.
+尽可能通过基于[插件](../plugins.html)的加载机制使用支持的文件系统。未来的 Flink 版本将不再支持通过 `lib` 目录加载文件系统组件。
-## Adding a new pluggable File System implementation
+## 添加新的外部文件系统实现
-File systems are represented via the `org.apache.flink.core.fs.FileSystem` class, which captures the ways to access and modify files and objects in that file system.
+文件系统由类 `org.apache.flink.core.fs.FileSystem` 表示，该类定义了访问与修改文件系统中文件与对象的方法。

-The file system used for a particular file is determined by its URI scheme.
-For example, `file:///home/user/text.txt` refers to a file in the local file system, while `hdfs://namenode:50010/data/user/text.txt` is a file in a specific HDFS cluster.
+文件使用的文件系统通过其 URI Scheme 指定。例如 `file:///home/user/text.txt` 表示一个在本地文件系统中的文件，`hdfs://namenode:50010/data/user/text.txt` 表示一个在指定 HDFS 集群中的文件。
-File system instances are instantiated once per process and then cached/pooled, to avoid configuration overhead per stream creation and to enforce certain constraints, such as connection/stream limits.
+文件系统在每个进程实例化一次，然后进行缓存/池化，从而避免每次创建流时的配置开销，并强制执行特定的约束，如连接/流的限制。
