If I could get in a time machine and go back to 2015, and do this course then, this would have been a five star (or maybe four and a half) course. It's an introduction to the ideas behind the technologies and I think back then it would been really really good. The theoretical underpinnings are still good. Clearly a lot of work and attention went into it.

Sadly, the course has been left to fester and rot. There don't appear to have been any updates since around 2017, and a certain amount of the coursework is impossible with the tools they provide you with. Be prepared to have to figure out how old Python programs work in Python 2 and work around the fact that their ClouderaVM cannot get vital updates that you NEED in order to the exercises. It will be an uphill battle trying to get the tech to work. It's so so sad as this clearly was a labour of love from the designers, and there are a few things - like the real time Twitter plot graph - that would have been amazing when they worked. Now, alas, the modules and the authorisations are so different that you will have to do a lot of reasonably advanced work to get any of it even operate at a minimum level.

The discussion forums are useful to an extent, but no-one from the course seems to have paid much attention to it. Think of it as an old abandoned funfair that used to be amazing, where you can still go on some of the rides but where some of them only work if you've brought a spanner and some tech know-how.

This is a difficult subject to teach in an online introduction course, but this was assembled poorly and in need of a reboot. The lectures appear dated, lengthy, and lack much substance (outside of the final lecture). The final, peer graded assessment is a joke. 5/6 peer assignments I graded were the exact, word-for-word copied answers from an internet source. I received a failing review on my first submission with 0 explanation for the grades. I spent the majority of my time in this course not gaining knowledge about BDM, but overcoming bugs associated with running outdated Oracle VM and petitioning to get valid reviews of my final assessment. Easily the worst course taken so far on Coursera.

The course a materials are interesting and with significant value, same comment on the teachers, this would be perfect if the third party(the VM) is working fine, I can't say I'm happy about the course where the frustration is probably the right word describing my feeling right now, wish me luck for this week, I might pass might not ......

I think some real polish needs to be applied to the final assignment in this course. Some of the questions are not formatted well for the coursera web site.. and even on my macbook pro retina I am seeing text overrunning the text box. Really want to see UCSD represented better

Cannot finish Twitter activities as commands shown in the video apparently don´t work with the most recent pyhton version. I am very disappointed about it, since I am mostly focused on Twitter-related data.

The course does not add much knowledge if you came from computer science field. It touches the very basics. The exercises are simple, and the final project is very vague.

Very poor in practical content. The maximum you will see is to run done python scripts in the virtual machine; But you can also run in your personal PC.

I wish the courses are more project oriented. This is a very good introduction but, atleast you could provide some optional projects or some tasks.

The content is good but this course needs an extensive update of the course material (labs and power point presentations).

I spent a lot of time setting up VM, as packages from python and libreoffice wasn't working

I have found this course less attractive to follow than other Big Data courses

Barely an introduction, it could be somehow merged with the course #1

some concepts are too concisely explained to get on clearly

The material seem buggy. I cannot proceed in the exercise.

Too simple for a persona that's already in the BI industry

Too simple.

Worst course I had ever. The hands-on materials are out of date. The teachers are not available for discussions. The course in unclear. Even, the final project description is ambiguous. Waste of time and money

It uses technologies which has no support, and the activities where there are problems reported by the users, are days ago abandoned by the moderators.

Very old course and all hands on materials are outdated and you spend more time figuring it out than the actual course

Too slow and i didnt get a certificate after completing course 1.

Setup with the virtual enviroment does not work.

Not worth your time or money.
