| <title>简介</title> |
| <p>Hadoop On Demand(HOD)是一个能在大型物理集群上供应虚拟hadoop集群的系统。它使用Torque资源管理器分配节点。它可以在分配的节点上启动Hadoop Map/Reduce和HDFS的守护进程。它会自动为Hadoop守护进程和客户端生成合适的配置文件（hadoop-site.xml）。HOD还可以将Hadoop分发到它分配出来的虚拟Hadoop集群的节点上。简而言之，HOD使管理员和用户轻松地快速搭建和使用hadoop。它也是Hadoop开发人员和测试人员非常有用的一个工具，他们可以使用HOD共享一个物理集群来测试各自的Hadoop版本。</p> |
