This document discusses why Hadoop is important to learn. It predicts that by 2020 there will be 40 zettabytes of data in the world and big data is being used by companies like Amazon, Twitter, and stock markets. Hadoop allows for the use of big data by being fast, flexible, scalable, cost effective and fault tolerant. The document outlines career paths working with Hadoop and that 2015 will see further adoption by enterprises and emergence of Hadoop distributions from companies like IBM. It concludes by answering that it is the right time to learn Hadoop due to its proven worth, growing adoption, disappearing skills shortage, and job opportunities.

Application of Big Data
Amazon handles 15 million
customer click stream user
data per day to
recommend products.
Stock market generates about one
terabyte of new trade data per day
to perform stock trading analytics to
determine trends for optimal trades.
294 billion emails sent every
day. Services analyse this data
to find the spams.
Systems / Enterprises generate huge amount of data from Terabytes to Petabytes of information

Can’t use Big Data without Hadoop
Current Scenario:
 Unstructured Data is Exploding
 Organizations take fact based decisions
 The Bigger the data, accurate is the decision!
Conclusion:
The use of Big Data is essential
 To Enable the use of Big Data one needs “Hadoop”
