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.

Best course taking into account the first three. Good material, more in depth than the other ones. Very well explained. Useful to get a sense of various interesting topics and orientative.

The final pyspark project was too hard for me and I don't exactly understand without massive python knowledge how can this be solvable, while the weeks lessons were way too easy compare to this final project.
This whole course was a little bit too superficial, without comprehensive tasks.

Interesting material and good lectures however some of the hands-on work was difficult / impossible to complete due to issues with SparkSQL, which have gone unanswered in the discussion forums, so had to export the data and use other tools to perform those analyses.

Low score because professor team/staff seemed to completely ignore discussion forums. A lot of participants have had problems running shell scripts and other setup instructions that are necessary to perform some tasks, and their posts have been ignored.

Tedious exercises through VM where instructions oftentimes do not work out of the box. It is a hassle to download the slides in small sets and their design awful. Definitely one of the worse courses I have taken.

The supplied tools are broken in hard to debug ways, as is evident from the discussion forums, where literally thousands of questions are raised. Somebody should do sentiment analysis on these forums, I suppose.

Quizes are inconsistent with given dataset. Questions are bad: i.e. what is the difference between "number of distinct countries mentioned" and "number of countries mentioned in tweets".

La virtual box de cloudera va muy lenta y es imposible hacer los ejercicios de manera fluida y satisfactoria.

I miss a proper buildup from the theory to the practical exercises. Especially the last quiz I found very difficult based on the limited number of exercises presented upfront.

Practice activities files are outdated and a lot of the installation of downloaded tools requires manual fixing, there is no support at all from the course publishers.

Links do not work and you must spent a lot of time in the Discussion Forum to know how to run the programs.
Instructions for the quiz are not clear and confused

I had many problems with the final two programming assignments with running Spark in the VM and there isn't a lot of help available online.

The materials explaining the course are too poor. This is a core course in the specialization.
The quizzes are out of the material's league

Too many different software packages, not enough depth, and no support. Good high level overview.

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 firstname.lastname@example.org. 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

To avoid. For 4 years, instructors / Coursera / UCSD have never updated the course. In this course, when you follow the instructions "localhost: 8889" it doesn't work, you have to go through the terminal to start pyspark. In addition, the connection ports have been obsolete for over 4 years, therefore the function "rtd.hpwren.ucsd.edu", 12028) (or 12024, 12020) does not work. Students are left to fend for themselves, wasting their time finding solutions in forums where unanswered questions to the same issues were asked 4 years ago. Even their VM is obsolete and no longer supported by Coursera. Find other Big Data training if you want to have a higher level training. If I could put a negative star on this course, I would.

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.
