Hadoop Introduction

I was browsing around when I chanced upon Hadoop. Now what exactly is Hadoop? Hadoop is a framework written in Java that allows you to write applications that will run in clusters of computers to process a large amount of data. Hadoop can work on single server to thousands of machines. You can even check out database design and database normalization

Below is a picture of Hadoop File System architecture. Hopefully it can give us a clearer picture of what HDFS is all about.

These are some of the Big Data Examples on internet usage as shown below:
