What is Hadoop?
Hadoop is a frame work written in Java language which allows us to deals with large set of data using a simple programming model. The two core components of Hadoop are, HDFS – Hadoop Distributed file system for storage. Map Reduce – A programming model to process the data. Using Hadoop framework it is very easy to store and process the different variety and the huge volume of data.. Initially this open source framework started with just two core components – HDFS and map reduce. But later on there are more than 15 components were integrated to the ecosystem.
What we do at Besant Technologies, OMR for Hadoop?
We always encourage the students to explore more on all the components; as a result the candidates from every batch are able to deliver a PROOF OF CONCEPT. Below are some of the POCs done by our previous batch students
- A Web page added to HDFS web UI to upload the files to hadoop distributed file system.
- A complete English – English Dictionary application using MAP REDUCE program.
Whom Hadoop is suitable for?
Hadoop and Big Data related Technology is suitable for all the IT professionals who look forward to become Data Analyst / Data Scientist in future and those who have a good passion towards data handling techniques and to become industry experts on the same. Moreover, hadoop can be pursued by Java as well as non- Java background professionals (including Mainframe, DWH etc.)
Job Opportunity for hadoop?
The demand for Hadoop skills never dies as this technology is like the reactant of a chain reaction where one leads to the growth or creation of another. As we are living in Internet era, we know how much of data is getting generated every day in every aspects of our life starting from the social media, e-commerce, banking, etc… So, it is indispensible need to handle the data. A growing number of companies have begun to tap the technology to store and analyze petabytes of data such as weblogs, click stream data and social media content to gain better insights about their customers and their business. Hence there is a very huge demand for Hadoop professionals.
