摘要
Hadoop是一个可实现大规模分布式计算的开源软件平台,已经被广泛应用在云计算领域。本文从Hadoop分布式文件系统架构的整体入手,对其分布式数据存储、分布式任务分配、分布式并行计算和分布式数据库四方面进行了分析。使开发人员深入地理解了Hadoop架构的工作原理与实现过程,为云计算背景下的应用程序开发提供重要的参考。
Hadoop is an open-source software platform which can achieve large-scale distribution computation.It has been widely used in cloud computing.The paper starts from Hadoop distributed file system and analyses distributed data storage,task allocation,parallel computation and database.It makes developers know the working principle and implementation procedure of Hadoop structure.It provides important reference for development of the application program under cloud computing background.
