Docker on YARN Node. Manager提供三种Container. Executor实现： Default. Container. Executor：以管理员身份运行Container启动脚本。 Linux. Container. Executor：以Container所属用户身份运行Container启 动脚本。使用cgroups进行资源隔离。 Docker. Container. Executor：在Docker中运行Container。

总结 • 设计目标：资源统一管理与调度平台 • 基本组件： Client Node. Manager Resource. Manager Application. Master • 调度器： 基于队列 FIFO、Capacity、Fair • 修改Node. Manager执行器支持Docker • 支持的框架： Hbase Spark Storm … 可方便的扩展
