Difficult for newbies, but good for intermediate

I learned some useful information and got some experience in working with Hadoop MapReduce and Apache Spark, even though there was plenty about the course that made it a real headache. I do feel like I spent much more time trying to figure out how to make my answers pass the autograder rather than learning how to structure my code to solve big data problems. Even though I won't bother to finish this course, because I don't need it to get a new job right now, I figure that what I have learned will give me a headstart if and when I really do need to learn this material.

There are a lot of unclear things about the homeworks. So even when you can run your homework successfully in the docker image, you still can't pass the online tests. Besides, the error msgs shown by online test system (not logs) are also unclear. It can't tell you the real reason of failure.

This course system had lots of bugs in grader system as well in the practice environment. Also the course journey was not suitable for a beginner point of view.

Task is easy, but takes a lot of time for debbuging on hdfs and understending whats wrong with submission.

fantastic content, terrible English.

Interesting material, but roughly structured, and the assignments are ambitious in scope but poorly executed

extremely difficult to understand some of the trainers, lots of errors, hard to follow material presented, lots of material tested but not covered well in training.

garbage

It was absolutely a great learning experience with Yandex. Many of doubt got cleared after watching these awesome videos.Lectures have in depth knowledge and understanding about Bigdata and Spark.Looking forward for the next course.

The instructors teach very well, and the course content is excellent. The assignments are also good, and touch the taught course contents comprehensively. Overall a great introduction to Hadoop and Spark.

Absolutely essential for everyone who wants a proper introduction to HDFS, MapReduce and Spark. Brought to you by a great team of geniuses of their time ;)

Gostei muito do curso, espero poder me dedicar mais nas próximas semanas

I really enjoyed the course, I hope I can dedicate more in the coming weeks

The course gave me more techical skill with Hadoop and Spark that help me can confidence in my career. Thank coursera and yandex so much.

lots of content to learn from. sometimes it is hard to understand what the lecturer is saying. Assignments are really tough too

I am very glad that I completed this course, everything is extremely affordable. Teachers are competent and erudite

A well structured, to the point description, well designed exercises taught by brilliant instructors.

This course offers an understandable way to start working on Big Data! Highly recommended

Very great course for beginner in mapreduce...In detail and working map reduce knowledge

The nice and helpful course as usual because it was made by Yandex and BDTeam

This course really takes you deep into Hadoop with the technical stuff.

This course very nice and cool, sometimes I want just stop it =)

This week was pretty good and insightful around Map Reduce

Awesome course, goes very deep into the details.

Excellent course content covering in depth.
