To many wrong subtitles, to little explanation for people who wouldnt know how to find stuff out for them selves. I have been working on the week 2 exam for 2 hours because my downloadfile was in the wrong directory.... you should make ik way more easy for students to learn and not fix your faulty explanations in the downloading and installing part of the course. The theory part is great.

The course was informative but some of the scripts in the exercises were wrong. Example is WGET for example has to be changed to CURL. I spent countless hours just on figuring out what is wrong. There is no support to ask about the any issues with the lab except for the coursera community. The community is supportive, it's just that they dont give the best answers at times.

In this course a virtual machine is used that can no longer be updated. Also it is no longer impossible to install software with the machine's package manager which makes the setup as described in the course impossible. Participants of this course need to find a workaround themselves which is most likely not possible for all. Without this issue this course would be great

Material out of date. Virtual Machine set up does not run properly. The forum is full of people asking for help with errors and nobody cares. It is extremely frustrating if you spend half your weekend trying to fix a problem that should not be there in the first place if someone cared for this course in the past 4 years.

I would not recommend this course to beginners as youtube courses are better because of the fact that they are not teaching the basics at all, also there is a significant gap between what they should tell and what should be told. I would rather learn on my own. They do not know how to teach at all.

While the concepts and materials are good in general, the final project quiz is terrible. It has outdated guides, unclear instructions and out-of-sync hints.

If you want to torture yourself, feel free to try it. If you know nothing about linux or coding, forget about completing this course.

I tried giving zero stars. This course is very poor. In particular the last portion of the class wherein you are tested on things that were not taught. If I had wanted to spend hours in google trying to learn this stuff I would not have spent money on this course.

Final assignment is not working properly. Whatever you choose - you are right.

There is no enough information how to dump tweets into file and how to use that in assignment.

This course doesn't worth any cent and should be either reworked or excluded.

Forcing users to install demo software which requires a registration is just too lame.

Other than that, courser is very boring, introductory, jumps constantly between things and doesn't explain much. Stack overflow and 2 hours would do a better job.

Outdated exercises with no support from instructors or mentors. Many students just cannot finish the courses. This is a shame to keep this PAID course on the platform if nobody is able to keep it up to date or to provide alternative solutions.

I have enrolled in this twice but can't see the course content. Every time I click "go to course" I get directed to the description of the course. Where are the lecture videos and other course content?

Instructors were not responsive at all. Many of the participants faced technical issues in the hands-on exercises involving Spark. Questions in the discussion boards were never answered.

One cannot do anything. One is just busy installing the required software, which only works partially, because the course content have not been updated for several years.

No followup from course mentors and admin. A lot of the software also had bugs and caused errors, which is why there was a need for mentors assistance.

The course is ok until the final project which is totally not compatible with the level of the hands on during the course ,the final project is a mess

Les fonctions ne fonctionnent pas sur Jupyter. Il faut revoir ces TP !! j'ai perdu beaucoup de temps à chercher sur internet les bonnes fonctions.

It's a good course but sadly there is no support from TA. Cloudera Virtual Machine Does not work well. I have to use a Docker image of pyspark.

anaconda file not working when bigdata3 file is extracted. Very bad experience in doing the project. Local host 8889 not opeening. Dont know why

The course cost too much for the gain of knowledge. Feels like this course could be merge with the first or the third course.

the programming assignments are designed very poorly. it takes lot of time to install and trouble shoot the installation.

Poorly designed, no help whatsoever from the staff, Forum is totally worthless. Worst course I ever had on Coursera.

It is very difficult when the environments don't work. This course has been very difficult to navigate

No any support, the soft versions are old. The control data in quiz does not correspond to real data

the quiz at the end is impossible to solve with the course content.

Materials for hands on exercies are not working. Bad stuff
