MapReduce program to analyse the production activities of a Book Publication House
##Data set Description: The Book-Crossing dataset consists of 3 tables.
##BX-Users: This file contains the list of the users, their age and where they are collected. If that data is unavailable for any field then it is filled with NULL.
##BX-Books:
It gives us the details about the book such as Book-Title, Book-Author, Year-Of-Publication,
Publisher, Image-URL and ISBN. Here ISBN will act as a unique code for a book. Invalid ISBNs
have already been removed from the dataset. URLs linking to cover images are also given, appearing
in three different flavors (Image-URL-S, Image-URL-M, Image-URL-L) i.e. small, medium, large.
These URLs point to the Amazon web site.
#BX-Book-Ratings: It contains the book rating information. Ratings are either explicitly expressed on a scale from 1-10 (higher values denoting higher appreciation) or implicitly expressed by 0.
##Goal:
- To find out the frequency of books published each year.
- To find out the frequency of books published every 5 year.
- To find out the frequency of books published every 10 years.
- To find out which year maximum number of books was published.
- To find out how many book were published based on ranking in the year 2002.
