growth in data volume. Every day people create unstructured large datasets of different types such as GPS coordinates, payment transactions, web data, e-mails or smart meter values that are termed as "big data" \cite{nasscom}. The need to derive useful information from such data requires the development of specific tools that are based on techniques as data mining, statistics, artificial intelligence, neural networks and other advanced analytics methods \cite{russom}. The analysis of big data is widely

huge demand to store, process and carefully study this large amount of data to make it usable. Hadoop is definitely the preferred framework to analyze the data of this magnitude. 4.1 Hadoop Data Analysis Technologies While Hadoop provides the ability to collect data on HDFS (Hadoop Distributed File System), there are many applications available in the market (like MapReduce, Pig and Hive) that can be used to analyze the data. Let us first take a closer look at all three applications and then analyze
