Welcome to the domain of Big Data – Hadoop Part 1

Hi all welcome to the domain of Big data – Hadoop, Myself sachin will share my experience to you through this journey. Today , Big data is a common buzzword in IT and it is important to know what it means. Where did the phrase Big Data come from and what does it mean? The phrase Big Data comes from the computational sciences. Specifically, it is used to describe scenarios where the volume and variety of data types overwhelm the existing tools to store and process it. In 2001, the industry analyst Doug Laney described Big Data using the three V’s of volume, velocity, and variety. Volume refers to the amount of data being generated. Think in terms of gigabytes, terabytes, and petabytes. Many systems and applications are just not able to store, let alone ingest or process, that much data.
