4步快速使用MapReduce服务

上传数据

如果您没有购买集群，请上传程序和数据到对象存储服务（OBS）中；如果您已经购买了集群，请上传程序和数据到HDFS。

购买集群

进入MapReduce管理控制台，单击“购买集群”并配置相关参数。用户可以指定集群类型用于离线数据分析和流处理任务，指定集群中预置的弹性云服务器实例规格、实例数量、数据盘类型、要安装的组件。

提交作业

您可以通过MRS控制台界面提交作业，也可以通过MRS集群节点使用命令提交作业。

查看作业执行结果

可在每个集群的“作业管理”页签查看作业运行记录和查询结果或者下载分析结果。也可以将结果转储到用户OBS上，转储成功后，使用OBS工具下载文件，查看结果。
