What is Hadoop?
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.

Big Data and Hadoop Various Domains
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.
Education
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.
