What it is, and why we need it?
With Big data, there was a requirement of a faultless system, for processing, parsing, storing, and retrieving such Big data. We cannot do this through the traditional database. They cannot store the data coming out of heterogeneous sources. Also, they cannot process fast the big data.

Here comes the Hadoop

Hadoop is an open-source software framework developed in 2008, for storing and processing Big data. It comes with huge processing power as well as the capability of parallel processing and handling any number of jobs.
Hadoop comes with unique features and can store large data. It cannot process as fast as Spark as its cluster-based programming, though Hadoop too is quite fast and cheaper. It also ensures fault tolerance, scalability and as mentioned is more cost-effective. And that is why various businesses still go for Hadoop. And it is not just a word, it's an entire ecosystem which we call the Hadoop ecosystem which is another reason for the companies going for Hadoop for big data analysis. It caters to us all required for big data analysis under one roof.
And ...
... that is why the Hadoop market is seeing growth each day and has a good future in front of it hence. Also, Spark can work over the HDFS from Hadoop, and hence you can easily become a Spark developer if you know Hadoop in deep.

Big Data and Hadoop in various Domain
Hadoop is on large scale helping various businesses in solving their issues in various domains, where they are being run.

Banking and Finance
This industry is facing real challenges like tick analytics, card frauds, credit risk reporting at various levels, audit trail archival, and various others. Hadoop is used to ensure early warning of fraud as well as trade prominence. This sector makes use of Hadoop in transforming and analyzing the customer data to come up with highly accurate insights, as well as decision support analytics before the trade.

Media, Entertainment and Communication

These sectors are facing challenges in the collection of analysis of the consumer data for squeezing out the insights, coming up in real-time the patterns, making use of social media, as well as analyzing content from mobile. Through Hadoop, these companies can analyze all these and come up with more accurate insights, and formulate personalized content.
Like Coca Cola can use it for finding the countries where the demand is huge and a complete insight based on various metrics for Cold drink consumption.

In Healthcare

Hadoop can analyze patient history, and various other histories related to the patients, and hospitals can come up with a more elaborate report about the patients that their doctors treat. And thus, they can serve the patients better. Also, it helps in disease identification, and a list of the precautions to be taken by the patients, as well as if the medicine is available for the patient in the hospitals and many such questions.
Various universities are making use of the public health data as well as Google Maps for visualizing the data which ensures faster identification of the spreading of various diseases and various queries like that.


Various universities are up with learning management systems and track the log time of the students and a detailed research report of the student's presence in the LMS. And thus, they can analyze the overall performance report of the students over some time, and from time to time. A detailed analysis ensures better education and growth of the students. Hadoop is used for such analysis.


Government executes various schemes, and they make use of the big data for detecting and studying various patterns, and squeezing various insights out of the data collected.
