I'm forced to give 5 stars. I don't want to have a certification on a poor quality course (another coursera mistake). This material needs tremendous amount of work to get finished and revised.

Super hands on introduction to key Hadoop components, such as Spark, Map Reduce, Hive, Pig, HBase, HDFS, YARN, Squoop and Flume.\n\nI can't wait to the next course on the specialization.

Very poor quality of both video luctures and exercises: knowledge required to complete tasks often not related to lectures or overall average skillset.
Lots of tecnical issues with software needed to complete course.
No help from TAs at all, students only helped by other students.

Very bad design. The instructor is nervous and not well prepared. The contents are very redundant, they keep repeating the general definitions but neither go deeply inside nor provide some application examples. I regret to take this course and waste time and money.

I took this course as part of "Big Data" specialization.
Unfortunately after taking break for half year the specialization changed and currently this course is not part of active "Big Data" specialization.
I cannot buy the complete specialization and cannot take single courses because specialization surprisingly can change so I prefer not to take more courses by this platform.

Too vague, many things have not been well explained. Sometimes quizzes are hard compared to the explained materials; assignments are not also explained appropiately. Think also San Diego Supercomputing Centre should provide resources for more realistic assignments rather than providing a virtual machine that needs high local resources.

The instructors just review everything so fast. They don't intend to teach you something they just want to review their knowledge.

This course is bad, in every possible sense. The video is rambling nonsense. The quizzes are arbitrary. There's no homework, no assignments, no projects, no learning.
The first course in this series shared many of these problems but did include a lesson involving installation of cloudera's VM, which was very useful, however simply installing the VM and going through their tutorial is the most learning you'll get from the first two months of this specialization.

This Course is very unsuitable for total beginners, the instructors use high level terms without actually bothering to explain them. The instructors are not explaining anything except reading out their prepared slides.I can only understand the course as I have some amount of experience at using Hadoop at my previous job. I have taken many courses on Coursera , this is by far the worst course I have taken. I regret paying for this course.

Lectures are very bad explained, ambiguous definitions, leading to very hard quizzes.
Also some exercises have python syntax errors which for me it's not a problem since I have a background as python developer but it surely has been a pain for people without programming experience.

It looks like the presenters have put very little effort into this.

The course is slow and bored. Only the surface is explained without detail.

I have an Ubuntu machine and found it difficult to install Cloudera's QuickStart VM. Very little help found on the web as well. Please, provide some documentation as to how one can install this software. Thanks!

There's no way to complete the course if you don't have previous coding experience (and they DO NOT mention it before, actually, they say you don't need it). The staff also do not help to complete the assignments. The lectures are poor as well.

If I can't upload my assignments , I can't contact with a teacher and I am evaluated what kind of course is this.

This course was more challenging and well explained, there are still some things that I think are missing, in some of the quiz questions, I could not find reference from the slides/presentations, even though we need to self learn this using more material I'd like to get more material like recommended books, online sites (besides the apache technical guides or hortonworks).
Feedback: Most of the learners that did not complete this specialization before the new version was launched are going to hang there not being able to complete the old specialization (2015) because of the Coursera Platform technical limitations. Please, if you plan to take a specialization, try to complete ASAP as apparently if a newer version comes, they won't care about the old version learners.

Labs have inaccurate and insufficient instructions, tests are ambiguous and include material not covered in the videos.

Having to do python scripting without any assistance and incomplete instructions has wasted an inordinate amount of time. Either you need to make python a prerequisite or give step by step instructions without having to interpret the code. This has been so frustrating that I do not think I'll ever use Coursera again. Too bad, because I was really looking forward to learning Hadoop. Now I'll have to find an alternate method to learn it.
