Hortworks 作为Apache Hadoop2.0社区的开拓者,构建了一套自己的Hadoop生态圈,包括存储数据的HDFS,资源管理框架YARN,计算模型MAPREDUCE.TEZ等,服务于数据平台的PIG.HIVE&HCATALOG.HBASE,HDFS存储的数据通过FLUME和SQOOP导入导出,集群监控AMBARI.数据生命周期管理FALCON.作业调度系统OOZIE.本文简要介绍了各个系统的概念.另外大多系统都通过Apache开源,读者可以自行下载试用. Hortworks Had

This document is a starting point for users working with Hadoop Distributed File System (HDFS) either as a part of a Hadoop cluster or as a stand-alone general purpose distributed file system. While HDFS is designed to "just work" in many enviro
1 Hadoop是什么? Google公司发表了两篇论文:一篇论文是“The Google File System”,介绍如何实现分布式地存储海量数据:另一篇论文是“Mapreduce:Simplified Data Processing on Large Clusters”,介绍如何对分布式大规模数据进行处理.Doug Cutting在这两篇论文的启发下,基于OSS(Open Source software)的思想实现了这两篇论文中的原理,从而Hadoop诞生了. Hadoop是一种开源的适合
