To process the huge volume of data in Hadoop cluster MapReduce framework is used. MapReduce is a framework which is written in Java. To get meaningful information from the data you have to write code in terms of map and reduce logic. Map phase performed parallelly on different nodes where as reduce phase aggregates the output from different map phase. Map and Reduce phase is driven by the Driver code. MapReduce code can be written in Java, C++, Ruby, and Python. I am a Hortonworks certified Hadoop Developer. http://bcert.me/swfssczm read less

Hello, I am Ali from Hyderabad, and I am into Telecom field as a Network Performance Engineer from the past 3 years, and as I don't find any growth in Telecom Field due to stability I am thinking to switch into IT field. And so far whatever I have researched I found Big Data is the demand in IT sector. 1. Can a non-IT guy with no programming/coding knowledge can step into Big Data? 2. How much scope does Big Data have or for how much years can we except Big Data around? 3. If I opt the course into your institute, will there be any real-time exposure during the course? 4. Can I easily get a job into Big Data as I am a non-IT person? And any experts or who have already taken course from any Institution and got helped in getting placements, please do suggest me which would be the best.

Can anyone suggest about Hadoop?
Hadoop is good but it depends on your experience. If you don't know basic java, linux, shell scripting. Hadoop is not beneficial for you.
