Spark SQL and Spark 3 using Scala Hands-On with Labs (Udemy.com)

Excellent course for practice CCA 175 certification exam. It helps me a lot to get used to with the certification environment and solving the questions with in given time for exam. I passed the exam using this course. The only improvement could be now Cloudera certification comes with 9 question which you can answer with API or SQL . Hence RDD solutions kind of no use now.

One of the most exhaustive material on big data stack . This tutorial surely gives lot confidence . Illustrations & examples cited , reflects practical use cases from IT world .. not just theoretical hello world sort of examples . The author has in depth knowledge of the Big data eco system and I thank him for helping me to venture into big data domain.

Wonderful Content Sir, Thank you for that. Also i feel this online udemy training is more advantage than a class room training, only small concern is that we may not get immediate help if we are struck somewhere as part of practice, but i hope we can get help from discuss.itversity as part of this course itself. Thank you once again.

It is amazing how much work has been put into this. For the last chapters the concept is getting a bit unclear: they have a lot of redundancy from previous chapters but do not contribute that strong (could be shortened by just giving the solution and pointing to previous chapters). The over-all time frame of 32 hours is very long (even if demands for other topics exist, this time frame – to my opinion - should not be extended).

I have finished this course recently. A very good real time examples explained in details. I have set up my own cluster and did practice. I love instructor effort a lot. This course is not for absolute beginner. He must have some prior knowledge into Big Data world and its eco-system. It will be very useful for them who didn't have practice well. Please do have this course into your bucket if you want to clear the exam. I have already purchased few courses from him and finished almost all. Got very nice grip. Subrat Gupta

I waited until I finished the course to write this review. You cannot properly evaluate a course after one or two lessons. I think Udemy does this, because most people won't finish the course anyway, so they ask for reviews early in the course. Anyway, this course is exactly what I needed. Durga, the instructor is experienced and gives in-depth explanations, and supporting information about coding, and frameworks, etc. I took the CCA-175 before taking this course, about 2 months ago, and I did not pass. This course really clarified some things for me, like solving business cases using core Spark and Scala APIs vs. SQL and Data-frames. I especially like Durga's course over others, because he actually shows you how to write the code in real-time, on-screen, and even makes mistakes, then corrects them. Other courses simply move at light-speed through the material, using code they have already pre-written and debugged, and also without giving proper explanation and context. Fortunately, Durga doesn't do this... This course is almost like being in a real classroom. I am also an instructor, and have delivered technical classroom training on subjects like Linux and Solaris to fortune 500 companies around the country. That being said, I appreciate the way Durga takes his time and clearly explains each topic, as well as telling you and showing you where to find additional information and resources. I have attended real classroom training before taking this course, and sadly I learned more from Durga. I also bought two other Big Data courses on Udemy. One was good, but not as good as Durga's, and the other just plain bombed! If you want to really learn how to code Hadoop, and Spark applications in Scala, especially how to write applications in Spark/Scala - get this course! It's the best one on Udemy! You won't be sorry! FYI: I also took an additional Scala Fundamentals course, and an SQL course while taking this one. I plan to sit for the CCA-175 again by the end of this month. I hope this helps someone.

WASTE OF MONEY!! COMPLETELY USELESS INSTRUCTOR!! ALWAYS ADVERTISES HIS CLUSTER!! Too many corrections in the lectures. Keeps changing the code and his statements. In Section 2 Lecture 15 at 6:24 he says after writing some code "If I run like this it will fail. Most likely, let us see". The code executes well and his reply "No, it didn't fail. That's good". Is he literally doing trial and error during the course? Not just once but happens a lot of times during the course. Unprofessional instructor, a complete waste of money. Expect at least​ some kind of professionalism and confidence when teaching a course online. For anyone thinking about joining the course, DON'T. It's a complete waste of money. They are using this platform to make people sign up for their cluster.

Anvar: 05/03/2018 Hello Durga I have taken the CCA 175 Ceritification Exam today and Passed successfully with 8 out of 9 questions. This Course is simply great and very Practical oriented and I am happy that I have learned Big-Data from this and got the cloudera certification. Thank you very much And Appreciated your effort. Thanks Anvar Roy S

Gadiraju explained each and every topic very much in details. Every command/function been explained using a use case which really helps to understand its applicability. It is really very good training and providing me utmost satisfactory feeling. Here we have only 5 start ratings. I would like to give more than 5 but here the limitation is 5 only.

Thanks Durga sir for well structured course, concepts are explained clearly with examples and easy to understand. I strongly recommend this course for anyone who have strong desire to learn Spark and big data. Thanks again for the great course. I have cleared my CCA175 exam last week. This course helped me to learn the exam related topics in details and helped me to clear the certification.
