Tutorial
This document serves as a tutorial to setup and run a simple application in Hadoop MapReduce framework A job in Hadoop MapReduce usually splits input data-set into independent chucks which are processed by map tasks Later the output form maps are sorted and then input to the reduce tasks Usually all the outputs are stored in file systems |

Introduction to MapReduce and Hadoop
Getting Started with Hadoop • Download from hadoop apache • To install locally unzip and set JAVA_HOME • Guide: hadoop apache org/common/docs/current/quickstart html • Three ways to write jobs: – Java API – Hadoop Streaming (for Python Perl etc) – Pipes API (C++) |
What is MapReduce ?
The term MapReduce refers to two separate and distinct tasks. The first is the map operation, takes a set of data and converts it into another set of data, where individual elements are broken down into tuples (key/value pairs).
What are the benefits of using Hadoop MapReduce?
The very first advantage is parallel processing. Using Map Reduce we can always process the data in parallel. As per the above diagram, there are five Slave Machines and some data are residing on these Machines. Here, the data gets processed parallelly using Hadoop Map Reduce and thus processing becomes fast.
What are the benefits of using MapReduce?
The major advantage of MapReduce is that it is easy to scale data processing over multiple computing nodes. Under the MapReduce model, the data processing primitives are called mappers and reducers. Decomposing a data processing application into mappers and reducers is sometimes nontrivial.
