They have employed over 100 illustrations and many worked-out examples to convey the concepts and methods used in big data, the inner workings of MapReduce, and single node/multi-node installation on physical/virtual machines. This book covers almost all the necessary information on Hadoop MapReduce for most online certification exams. Upon completing this book, readers will find it easy to understand other big data processing tools such as Spark, Storm, etc.

• understand what big data is and the factors that are involved
• understand the inner workings of MapReduce, which is essential for certification exams
• learn the features and weaknesses of MapReduce
• set up Hadoop clusters with 100s of physical/virtual machines
• create a virtual machine in AWS
• write MapReduce with Eclipse in a simple way
