Google的核心竞争技术是它的计算平台。Apache上就出现了一个类似的解决方案，目前它们都属亍Apache的Hadoop项目，对应的分删是： Chubby-->ZooKeeper GFS-->HDFS BigTable-->HBase MapReduce-->Hadoop 目前，基亍类似思想的Open Source项目迓径多，Hadoop是其中最为流行的框架，本文就将简要介绍hadoop的一个开发流程。-Hadoop got its start in Nutch. A few of us were attempting to build an open source

web search engine and having trouble managing computations running on even a

handful of computers. Once Google published its GFS and MapReduce papers, the

route became clear. They’d devised systems to solve precisely the problems we were

having with Nutch. So we started, two of us, half-time, to try to recreate these systems

as a part of Nutch
