What is Hadoop? 

An open-source framework written in Java, Hadoop allows distributed processing of large datasets across clusters of computers using simple programming models. Hadoop was first developed by Doug Cutting and Mike Cafarella. It has been designed to scale up from a single server to thousands of machines, each of them offering local computation as well as storage. A Hadoop framework application is built to work in an environment that provides storage across a cluster of computers. If you wish to learn more about the concept, you can also take up a Hadoop Map Reduce course and upskill today.

Hadoop mainly has two layers as shown below:

  • Processing/Computation layer (MapReduce), and
  • Storage layer (Hadoop Distributed File System).

Where is Hadoop used?

Hadoop can be used in various scenarios, such as-

  • Search – Yahoo, Amazon, Zvents
  • Log processing – Facebook, Yahoo
  • Data Warehouse – Facebook, AOL
  • Video and Image Analysis – New York Times, Eyealike 

Advantages of Hadoop


An estimate of 20% of data in organizations is structured and the rest is known to be unstructured data. It is extremely crucial to manage unstructured data that goes unattended. Hadoop can manage different types of data whether it is structured or unstructured. It is simple and relevant. Hadoop supports Java, but with the help of the MapReduce technique, any programming language can be used. It can be used on various operating systems such as BSD and OS X but works best on Windows or Linux. 


New nodes can easily be added to the systems when required. There is no requirement to alter data formats or modify existing applications to do so. It is an open-source platform and is fault-tolerant. This means that if a node goes out of service, the system automatically allocates work to another location and continues to work. 


Hadoop is loaded with great features and generates cost benefits by bringing parallel computing to commodity servers. This results in substantial cost reduction per terabyte of storage, in turn making it reasonable to model all our data.


Hadoop is becoming more and more real-time as it can stream information into a cluster and analyze it. A standard approach is provided to a wide set of APIs for big data Analytics which comprises MapReduce, query languages, and so on.

Which Companies are using Hadoop in India? 

There has been an increase in the use of Hadoop over the years. As of 2017, the Hadoop market was valued at $13.9 billion. With the growth in the market, the number of jobs and companies making use of Hadoop have increased as well, companies such as Google, Yahoo, Apple, Amazon, Oracle, Microsoft, EMC Corporation and many more are making use of Hadoop today.

Product Managers, Software testers, Database administrators, Hadoop Developers, Senior Hadoop Developers, etc., are required by these companies. These companies are looking to hire freshers as well as professionals with work experience, as long as they have the required skills and knowledge. Knowing AWS or Open-stack is a big plus point.

Managing Big Data has become a crucial requirement in most companies and the requirement of Hadoop skills is accelerating at an increasing pace. Check out these Hadoop courses to upskill yourself today!
