Hadoop MAPREDUCE in Depth | A Real-Time course on Mapreduce (Udemy.com)

Up to date October 2020. All programs work. Beginner friendly. The professor literally gives you a detailed Line by line explanation of every line of code with descriptive comments too. He literally turns a super hard subject into something a beginner can understand. I recommend basic java programming (build a project, OOP, loops, etc) and you should be good to start this course. Best investment ever!

First of all, I would like to thank you for this course. Useful and quite understandable for a person who is familiar and has some experience, but it is difficult to read source code. Some Ideas did not expand to the "A to Z" level. Maybe it could be better to improve the existed solutions, make it complex.

Very great and informative content on MapReduce frameworks. I gained great insight and understood deeper concepts like multiple mappers, customer informat formats and so forth. I got to understand the real-world use cases of MapReduce. Happy with the knowledge I have gained.

Even though the course covers all the topics about Mapreduce but it is very poorly made and very distructive presentation. There are plenty number of examples but input text files don't have headers, and its difficut to remember what represents every field. In addition, the questions in quizzes are unclear and confusing.

The course goes into good depth of map reduce, which is the unique feature to this course only. Other courses only explain basics of map reduce. How ever like all other Mapreduce courses this course also fails to setup initial premise and directly dive into technicalities. There should be videos like what is mapreduce, why we are learning, when and why to use, explaining terminologies. in first video Instructor uses words like Mapper and reducer when student doesn't even understand the context. Which is not unique to this course, every course on MR out there is like that. However if you have a basic knowledge of MR and you want to expand on that, then this course is the best one available. Instructor dives into great depths and cover almost all topics of MR. I would definitely recommend this course if you are looking to make career in Big Data.

See it is a very nice course. Since I am not from JAVA background and only know OOPS concepts so I was looking for such a course for a long time. I knew only theory of MR but did not know how to write even a wordcount program. Now finally I could write some MR programs after learning one by one code explanation from this course. Kudos to the instructor.

This course is excellent to understand the MapReduce concepts from basics to advance. After doing this course I have very much confident about my MR skills. The instructor is very much responsive to query. I will recommend this course to those who want to get the clear understanding of Mapreduce programming skills.

The course is so interesting and engaging that I finished it in just 1.5 days including the assignments. This course is a wish come true for absolute beginners who have zero knowledge of mapreduce. Guys, mark my words take this course and you wont repent. All it takes maximum 2 days to learn mapreduce from this course. And this instructor is very quick in answering questions. You will feel like you are chating with him and he wont mind answering any number of questions.

I had bought this course after reading the comments of other students. The 5 star ratings they have given to this course are clearly reflected in the content of this course. For ex- The resources, examples, and other course material the instructor has provided is very knowledgeable & up to the point. Obviously, very knowledgeable and experienced instructor.

Very informative and very easy to understand Mapreduce course, I would say! In my case, I grasp each and every thing in the very first go. A "must" course for people who want to learn Mapreduce. No need to join any institute to learn Hadoop, just buy courses on Udemy. You will learn more and pay less. Thanks Sir!
