Large businesses needed to go through terabytes and petabytes of data. This data was initially control by a single powerful computer. But due to its limitation, it can handle data up to certain limits. To solve this problem, Google publicized MapReduce. MapReduce : A system which supports distributed computing on large data sets on clusters. Many other businesses were facing the same problem of scaling. Therefore, Doug Cutting developed an open source version of MapReduce system called HADOOP.

Hadoop is framework of tools. The objective of hadoop is,it supports running application on big data. It is an open source set of tools and distributed under Apache License. It is powerful tool designed for deep analysis and transaction of very large data.

The keyword behind hadoop is BIG DATA. Big data facing challenges Velocity Variety Volume Big Data
