It was a good course, it could have been better if some examples of Spark were also provided in other Languages like Java, people without having background of python may find it difficult.

I think the last project was very badly positioned and explained. First the Coursera is using Cloudera VM, but if you execute and run the Cloudera Express to set the Cloundera environment up the Coursea exercises do not run There should be a warning!. If you do then the simplest Jupyter exercise it fails - this took me about 10 hours to figure out.
Then for the final Project, technically to succeed you must miss country names in all lower case and you cannot match with countries with a 'space' e.g. 'Cape Verdi' and if you try to take any of this into account you do not get the same numbers to pass the test. There needs to be some warning on how to interpret and manage the files so that you get the same numbers being asked for in the test. Again this too me about 10 hours to resolve. Both resolutions ONLY because another colleague is doing the same course and we problem solved together. THIS IS AN AWFUL EXERCISE in frustration due to incomplete details. Not a learning exercise. Just AWFUL....

In week 3 I was asked to give up my personal information to a 3rd party in order to complete this course, including full name, email, telephone, zip code and permission to send spam to my email. This is not acceptable.
As I used a fake telephone number they denied my registration:
Thank you for your interest in Splunk.
Please be patient as we assess your registration at Splunk.com. This process may take a few days. If you do not receive a welcome email from Splunk after 2 business days, feel free to contact email@example.com. Be sure to provide your full name, complete mailing address, email, and the Splunk.com username you created during your registration. We will respond as soon as possible. Thank you for your patience and understanding."
I'm pretty sure you can work something with Splunk to provide a direct link for future editions of this course so your students don't have to give up their privacy in order to complete it, as you're giving that company the publicity anyways.

Content-wise is okay.
Hands on material is not properly prepared. Software installation has some many errors, even the course is using a standard VM. This shows the provider paying little attention to prepare the course material. Very disappointing attitude.
Another error spotted, mongoexport give wrong instructions.. using the instruction, there is no way to extract just the tweets column. I really doubt if the instructors have ever tested on whatever they have provided to the students lol
I dont know how can i express my disappointment to this course. Quiz instructions are very unclear as well. If the instructors have ever tried their own instructions, they would discover these naive mistakes. Please be responsible when selling knowledge

The contents are too old, its time to upgrade. And it only has very less basic theory with lots of unnecessary theory part which dont even explains anything useful. In spark only wordcount example, nothing else. Not even efficient or useful even for a beginner. I will never recommend this course. Its better to choose free on very cheap courses in Udemy which have good content, practicals and examples. Or even youtube free courses are far better. Here they have included splunk, after going through the course I googled to understand what actually splunk is. Total waste. I am cancelling my subscription today.

While the teacher are excellent and the course enjoyable, the instructions are simply not working (especially week 6). Just check on the forums, the instructions are so outdated. The Internet changed. Many script must be debugged to add parameters like --no-check-ssl and add classpathes and without this, the test on week 6 is too hard without guessing and retrying. This a shame to sell courses that no longer work.
The whole course would need a serious refresh to get it working with some recent version. Remember, it is based on outdated software from 2014 or 2015.
Please update ! Thanks

I really liked the instructors. They have a really good way of showing the content and are very helpful. However, none of the examples in this whole course will work. The images used in the virtual machines are so old that they cannot be even updated anymore, because the servers changed and/or the linux distribution is not even developed anymore. Coursera has to immediately update this course and all the courses in this specialization! This is not fair with the student. Please, Coursera! I have always supported the work on the the platform. This was a great disappointment.

This course falls down a cliff almost instantly. The quizzes are based on terminology that is not yet introduced, the exercises barely scratch the surface of what is needed on the assignments. Reading in between the lines and hours of experimentation and trial and error are needed for the assignments and quizzes. That is not a way to learn. If you like to have the instructor just read off the slides and tell you to copy this, and run that, and not really understand what you are doing, then I guess this course is for you. I got nothing out of this course.

There have been major updates to the software, and the instructions in the course have not been updated to accommodate them. Neither have the moderators provided working solutions to the common technical problems in the discussions and forums nor can we find solutions pertaining to Cloudera on Google. The Hands-On exercises are totally impossible to be implemented at this stage due to lack of proper guidance.

This course was absolutely terrible. You spend 2 hours per assignment troubleshooting the install of the various tools used and literally no time do the assignments and experiments. Its like no one at the University even tried the steps that they published, they were simply incorrect. I am lucky to have a background using some of these tools. Course should be removed until content is corrected.

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.
