Let’s take Walmart for example. Walmart records nearly 1 million transactions per hour worldwide and sends it to their huge database on a regular basis. Now, analyzing all that data is important for Walmart to figure out customer preferences based on geographical location. specific product performance, likes and dislikes and many other customer oriented parameters.

Making sense of big heaps of data is the challenge here, a challenge Hadoop is ready to take by its horns! Hadoop is the perfect solution for handling the complexities of Big Data: High volume, velocity and variety of data. But what exactly is it?
