Hadoop MapReduce概念学习系列之MapReduce 资源组织方式（六）

　MapReduce计算框架并没有直接调用CPU和内存等多维度资源，它把多维度资源抽象为“slot”，用“slot” 来描述资源的数量。管理员可以在每个节点上单独配置slot个数。slot可以分为map slot和reduce slot。从一定程度上，slot可以看做“任务运行并行度”。如果某个节点配置了5个map slot，那么这个节点最多运行5个Map Task；如果某个节点配置了3个red....

你想知道的关于Hadoop数据资源池的一切

随着Hadoop数据资源池的概念进入主流IT，越来越多的企业开始试水Hadoop。但很多只是将一部分数据池化，还没有开发出成熟的Hadoop环境。数据资源池使用基于开源Hadoop框架和商业硬件，以池化资源的形式处理、存储和管理大数据，尤其是支持分析应用。支持者认为数据池架构提供了一个更便宜的替代传统数据仓库的选项，能够处理结构化、半结构化以及非结构化数据。不过，数据资源池的概念还相对较新，带....
