这篇文章是我来Hulu这一年做的主要工作,结合当下流行的两个开源方案Docker和YARN,提供了一套灵活的编程模型,目前支持DAG编程模型,将会支持长服务编程模型. 基于Voidbox,开发者可以很容易的写出一个分布式的框架,Docker作为运行的执行引擎,YARN作为集群资源的管理系统. 同时这篇文章也发表在Hulu官方的技术博客上:http://tech.hulu.com/blog/2015/08/06/voidbox-docker-on-yarn/ csdn在线:http://huiyi…

Overview ... YARN Architecture The fundamental idea of YARN is to split up the functionalities of resource management and job scheduling/monitoring into separate daemons. [基本思想是将资源管理和任务调度/监控分开.] The idea is to have a global ResourceManager(RM) and pe…

YARN Architecture Link: http://hadoop.apache.org/docs/r2.7.2/hadoop-yarn/hadoop-yarn-site/YARN.html YARN结构图.图中有两个Application,因此有两个ApplicationMaster.4个节点,其中一个节点运行ResourceManager,另外3个节点运行NodeManager. Yarn的基本思想就是让资源管理器和作业调度/监视器分别成为守护进程.RM和NM构成了数据计算框架. 1…
