For this problem, the concept of cloud computing is a more appropriate choice. In this thesis, based on the architecture of Hadoop with HDFS(Hadoop Distributed File System) and Hadoop MapReduce software framework and Pig Latin language, we design and implement an enterprise Weblog analysis system...
大多数云都在一定程度上遵守SOA(Service-Oriented Architecture,面向服务的架构)的设计规范。SOA的意思是将应用不同的功能拆分为多个服务,并通过定义良好的接口和契约来将这些服务连接起来,这样做的好处是能使整个系统松耦合,从而使整个系统能够通过不断演化来更好地为客户服务。而一个普通的云也同样由许许多多的服务组...

As we have seen, HBase classic data model is not designed with SQL in mind. Under the hood it is a sorted multidimensional Map. That is where Phoenix comes to the rescue; it offers a SQL skin on HBase. Phoenix is implemented as a JDBC driver. From architecture perspective a Java ...
Traditional relational database and distributed computing and data processing have been becoming more and more not suitable to the increasing network data. This paper establishs a multi-layer architecture based on Hadoop storage platform of Weibo public opinion application according to the characteristics...
2.1.The Hadoop Architecture on vSphere 当Hadoop被虚拟化后,Hadoop的所有组件的进程包括NameNode,ResourceManager,DataNode和NodeManager,都是在一组VM的OS中运行,而不是基于裸机的OS。这些进程有时被称为Hadoop服务或者守护进程。VM中包含与物理机器完全相同的进程,可以如图1进行布局。 本篇文档,我们使用术语虚机(virtua...
Hadoop Architecture(hadoop的架构) Hadoop公共框架 支持所有其他模块的Common Utilities HDFS:Hadoop Distributed File System: 跨越Hadoop集群中所有节点以进行数据存储的文件系统,链接本地节点上的文件系统,使它们成为一个大文件系统 分布式数据存储系统 Hadoop MapReduce: ...
Internally, a file is split into one or more blocks and these blocks are stored in a set of DataNodes. HDFS: Namenode and Datanode HDFS has a master/slave architecture The NameNode executes file system namespace operations like opening, closing, and renaming files and directories. It also ...
