+本页介绍如何通过以下组件在 Spark 中使用 Ozone 对象存储：
+
+ - OzoneFS (兼容 Hadoop 的文件系统)
+ - Hadoop 2.7 (包含在 Spark 发行包中)
+ - Kubernetes 的 Spark 调度器
+ - 本地 Spark 客户端
+
+
+## 准备
+
+下载 Spark 和 Ozone 的最新发行包并解压，本方法使用 `spark-2.4.0-bin-hadoop2.7` 进行了测试。
+
+你还需要准备以下内容：
+
+ * 用来上传下载 spark+ozone 镜像的仓库（本文档中使用 Docker Hub）
+ * 自定义镜像的名称，形如 repo/name（本文档中使用 _myrepo/ozone-spark_）
+ * 专门的 Kubernetes 命名空间（本文档中使用 _yournamespace_）
+
+## 为 driver 创建 docker 镜像
+
+### 创建 Spark driver/executor 基础镜像
+
+首先使用 Spark 的镜像创建工具创建一个镜像。
+在 Spark 发行包中运行以下命令：
+
+```bash
+./bin/docker-image-tool.sh -r myrepo -t 2.4.0 build
+```
+
+_注意_: 如果你使用 Minikube，需要加上 `-m` 参数来使用 Minikube 镜像的 docker 进程。
+
+```bash
+./bin/docker-image-tool.sh -m -r myrepo -t 2.4.0 build
+```
+
+`./bin/docker-image-tool.sh` 是 Spark 用来创建镜像的官方工具，上面的步骤会创建多个名为 _myrepo/spark_ 的 Spark 镜像，其中的第一个镜像用作接下来步骤的基础镜像。
+
+### 定制镜像
+
+创建一个用于定制镜像的目录。
+
+从集群中拷贝 `ozone-site.xml`：
+
+```bash
+kubectl cp om-0:/opt/hadoop/etc/hadoop/ozone-site.xml .
+```
+
+然后对它进行定制：
Review comment:
Original text:
> And create a custom `core-site.xml`.
It refers to `core-site.xml`, not `ozone-site.xml` below.
Suggestion:
> 然后创建 `core-site.xml`：
