This textbook adopts a unique approach to helping developers and CS students learn Hadoop MapReduce programming fast in an easy-to-setup, virtual 4-node Linux YARN cluster on a Windows laptop. Rather than filled with disjointed, piecemeal code snippets to show Hadoop MapReduce programming features one at a time, it is designed to place your total Hadoop MapReduce programming learning process in a common application context of mining customer spending patterns ensconced in large volumes of credit card transaction record data. Precise, end-to-end procedures are given to help you set up your Hadoop MapReduce development environment quickly on Eclipse with Maven on Windows. Step-by-step procedures are also given on how to set up a four-node Linux cluster at minimum so that you can run your MapReduce programs not only in local but also in standalone and fully distributed mode on a real cluster. In fact, all MapReduce programs presented in the book have been tested and verified on such a Linux cluster. This textbook mainly focuses on teaching Hadoop MapReduce programming in a scientific, objective, quantitative approach. Rather than heavily relying on subjective, verbose (and sometimes even pompous) textual descriptions with sparse code snippets, this textbook uses Hadoop Java APIs, Hadoop configuration parameters, complete MapReduce programs and their execution logs and outputs to demonstrate how Hadoop MapReduce framework works and how to write MapReduce programs. Specifically, this text covers the following subjects: * Introduction to Hadoop * Setting up a Linux Hadoop Cluster * The Hadoop Distributed FileSystem * MapReduce Job Orchestration and Workflows * Basic MapReduce Programming * Advanced MapReduce Programming * Hadoop Streaming * Hadoop Administration No matter what role you play on your team, this text can help you gain truly applicable Hadoop skills in a most effective and efficient manner. The book can also be used as a supplementary textbook for a distributed computing or Hadoop course offered to upper-division CS students.

This book adopts a unique approach to helping enterprise Java developers learn Spring 4 fast. Rather than filled with disjointed, piecemeal samples to show Spring features one at a time, it is designed to base your total Spring learning experience on a functioning, end-to-end integrated sample named SOBA (Secure Online Banking Application), which runs on any one of the three operating systems (Windows, Linux and Mac OS X), any one of the four Java App Servers (Tomcat, GlassFish, JBoss and WebLogic), and any one of the four RDBMS (MySQL, PostgreSQL, Oracle and SQL Server). The book also includes another standalone sample application named MyNotes, which is simpler than SOBA. Specifically, this book helps you learn the following latest Spring technologies: * Spring Core Framework * Spring MVC Web Framework * Spring Data Access Framework (JDBC and Hibernate) * Spring RESTful Web Services Framework * Spring Security Framework * Spring Transaction Management Framework * Spring Validation Framework * Spring Aspect Oriented Programming (AOP) Framework * Spring Testing * Spring Integration with EJB * Spring Web Flow Framework At the end of your learning experience with this book, you will gain truly applicable skills and will be able to start contributing to the success of your Spring-based enterprise application project immediately.
