Overview

Drive better business decisions with an overview of how big data is organized, analyzed, and interpreted. Apply your insights to real-world problems and questions. ********* Do you need to understand big data and how it will impact your business? This Specialization is for you. You will gain an understanding of what insights big data can provide through hands-on experience with the tools and systems used by big data scientists and engineers. Previous programming experience is not required! You will be guided through the basics of using Hadoop with MapReduce, Spark, Pig and Hive. By following along with provided code, you will experience how one can perform predictive modeling and leverage graph analytics to model problems. This specialization will prepare you to ask the right questions about data, communicate effectively with data scientists, and do basic exploration of large, complex datasets. In the final Capstone Project, developed in partnership with data software company Splunk, you’ll apply the skills you learned to do basic analyses of big data.

Good content - very poor execution, evaluation, and practical excercises This course has all the right stuff, but fails in the execution phase. Content is appropriate, but after course one, the level of instruction suffers greatly. Basically sets of slides with a person in the corner reading to you...

Terrible Offering for a highly-technical subject Completed the 4th course, Machine Learning with Big Data, in a mere 2 hours. Storming through videos at x2.0 speed, still can grasp everything. Why? Because the contents are so generic there's nothing to really capture. Most of the stuffs you can read...

Waste of time and money

Sad to say but this specialization (at least first 3 courses at the moment) is worst I saw on Coursera. Lecturers show no evidences of ability to teach, have no own materials, ask obscure questions during quizzes with data not covered in videos/slides nor official documentation of used software solutions.

All issues with assignments or software are not covered by staff members and you only can rely on other students help.

Material which covers topics from 1st part of spec is just words about how cool is to work with Hadoop and Hadoop-based products.

2nd course talks about basics you can grab from official documentation.

3d course includes parts not used in modern Big Data installations (try to find actual info on Pig usage).

Worst. Specialization. Ever.

I completed the first course of the series and started the second. Every other comment is spot on. There is ZERO effective instruction.

One of the "lectures" consisted of the instructor reading the online tutorial (but not admitting that she was just doing this). Worse yet, in the video, she overlooked some of the steps in the tutorial, so that any student who tried to follow the video step-by-step would be unable to replicate the instructor's results.

All of the videos were set up as Powerpoint presentations (even when they were trying to walk through some practical programming exercises). The quizzes were jokes, and the assignments were completely unrelated to the instruction videos.

Poor value

Dropped after the second course.

The introduction looked interesting, but the "Hadoop Platform and Application Framework" was extremely disappointing.

The lectures are not structured and presented in an interesting way (and copying illustrations from the web does not help). The lecturer reads the bullet points or a script, and repeats a lot of what was said in the previous course from the specialization. The coding exercises basically consist in copy/pasting code and execute it, while the quizzes test for simple facts.

I was considering doing the full specialization but I am glad I had a look at the content first, for the price one would expect much higher quality.

Finished first 3 courses out of 6.

I absolutely agree with others. Specialization is bad.

Yes, I learned something on the very (very, very) high level. I can download cloudera VM and perform some computations on the file that is more than the volume of RAM using Hue. But, of course, it is not the level that most of those who are interested in Hadoop was seeking for.

They try to teach you Hadoop on the level that is suitable maybe for Excel but nothing more than that.

Don't pay for it. Just check courses first (you can save your answers and take a certificate after that very fast).

Bugs in scripts, poor audio, glossing over important details lead to a poor learning experience

The title says it all. I've been in IT for over 35 years. I consider myself technically competent. I wanted exposure to Hadoop. I'm enrolled in the specialization. I spend the majority of my time trying to decipher the lecture (ironically, even subtitles flash [inaudible] on a regular basis) and understand the concepts presented at lightning speed. Thank goodness I'm proficient with UNIX and she'll scripting. Non-technical people should NOT take this course. Finally, zero support from UC.

Don't start here. Take more Python instead.

I took the first 3 of 6, and after reading these reviews decided not to proceed to 4. I put in the recommend effort and a bit extra.My grades were fine, but the courses don't seem fully tested or cooked. Get your python skills in order before tackling course 2. There are good resources on the internet to support you in the course outside of the course (manuals, tutorials, etc.). I took them out of curiousity. The other comments are pretty much on point. I did use Excel a few times to check/validate my results.

Interesting and good, even if not full satisfying for a software engineer

As a software developer with poor knowledge of the big data environment, I would say that this course is useful, it will open your mind to the infrastructure and algorithm used, but it does not goo so deep in technical details. But at least it scratch the surface of the Hadoop framework, so you end up with some more material to research on and you get in touch with the basic concept of the Big Data universe.

I would give no star if I had a choice

Poor quality material for the cost of the course.

Grading and peer assignments are a joke. Despite having correct assignments, there is a chance you will fail those assignments since peers who did not understand the course will evaluate you. There is no way to guarantee that experts will review your work.

Better to take free courses on big data and learn by yourself.

Badly delivered of an otherwise very interesting subject.

If you want to learn Big Data, go somewhere else. UCSD's Coursera specialization really screwed up. Materials are okay, but are badly organized and delivered, like scatter-brained. They also messed up royally on the final capstone, not only delayed 5-6 months, but also put out some really pitiful idea for the project.

Terrible

Don't buy this specialization. I'm on the 3rd course now, and If I knew it before I wouldn't take it even for free. Absolutely useless assignments and quizzes. Videos just reading intro tutorials. Practical assignments are not explained correctly. Tutors are absent from discussions.

They changes the specialization without notice and I lost all my work & money

Coursera changed the specialization without prior notice. I have finished 4 courses out of 5 and now I lost it all because they decided to change the specialization without prior notice. Quite a scam in my opinion.

The worst Coursera course ever. I wish I could give neagtive starts.

Steer away from this course. Waste of time and money.

They should return the money to everybody attending it with an letter of apology.

The only reason I finished it is because I paid for it.

complete waste of money

No content, very slow and absolutely not worth the money. Promised was 3 weeks of 3-5 hours a week of content/work. It was 1.5 hours ALLTOGETHER. False advertisement and no assistance from Coursera staff or UCSD.

Awful.

Course is poorly designed. Material is covered extremely superficially. Lectures have factual errors. Quizzes are poorly worded and dont really test understanding. Stay away from this course. It is a waste of time and money.
