说明：  程序源码,《Hadoop高级编程——构建与实现大数据解决方案》本书关注用于构建先进的、基于Hadoop的企业级应用的架构和方案，并为实现现实的解决方案提供深入的、代码级的讲解。本书还会带你领略数据设计以及数据设计如何影响实现。本书解释了MapReduce的工作原理，并展示了如何在MapReduce中重新定制特定的业务问题。在整本书中，你将会发现深入的Java代码示例，这些代码示例可以直接使用，它们均源自于已经成功地构建和部署的应用程序。
(Source program the Hadoop programming, construction and large data address scheme, the book concern for building advanced, based on Hadoop enterprise application architecture and solution, and for the realization of practical solutions provide in-depth, code level to explain. This book will show you how to understand the data design and data design to achieve. This book explains the working principle of MapReduce and shows how to re customize the specific business issues in MapReduce. Throughout this book, you will find the Java code example, which can be used directly, both of which are derived the application that has been successfully constructed and deployed.)
