I'm forced to give 5 stars. I don't want to have a certification on a poor quality course (another coursera mistake). This material needs tremendous amount of work to get finished and revised.

Learned about Hadoop Ecosystem, limitations of map-reduce approach and Spark as a solution to overcome some of limitations.Thanks for giving me the opportunity to participate in this MOOC.

This is one of the most disappointing classes I ever took on Coursera. I am a Coursera believer and have taken so many classes here. But with all due respect, the instructor in week 2 and 3 was just mumbling to himself in front of the camera. I feel kind of disrespected. This course is not well prepared and should not be on Coursera.

The instructor in week 2 makes me want to kill myself. There are people who can teach, there are people who can't teach, and there is this guy who absolutely cannot be allowed to teach due to safety reasons.

This is a good introductory course. The content is good, but the presentation is not great. The presenters speak with a low, mumbling voice.
The programming exercises could also be improved: they are based on a contrived example (TV shows and view counts). The presentation of the exercise gives several clues on how to progress on the exercise, but in at least one case, that was not straightforward and there was a simpler solution.

The course presents a general introduction to Hadoop world, but some explanations aren' t clear.
I appreciated links and references proposed to study other (ex. Python), and section quiz.
Are there problems with guides of Cloudera, but can be solved searching on the web (thank you Stackoverflow).
FInally, I didn't like sections presents by the Indian professor, because he "ate the words" and without underline text a lot of phrases were incomprehensible

I hope they update the virtual machine provided and the scripts. Getting the VM to work in its current state requires familiarity with linux (in order to solve the permissions issues among other things).
As for the theory and the pace of the lectures. I really concerned myself to have learnt about these subjects.
To the lecturers and the staff, Thank you very much!

Great simple course to get started in the Hadoop zoo. The VM provided makes getting set up easy enough and is a great tool for assignments. I'd encourage the course creators to keep the VM up to date however, as it's beginning to accrue technical problems. Make sure you skim the forums for issues with the VM!

Outdated (like what... 5y old?!)
A LOT of struggle with the old VM
Week1 is 1:1 the cloudera quickstart tutorial not even with additional comments
Liked the week 4&5 modules though but had to install spark locally

This is a very bad course. The VM image provided is very buggy and does not work. ( It took me 4 hours to make it to the second part of the first tutorial just to find out that the second part is broken due to miss-configured HUE server ). Professors do not respond to questions in forums as well. PLEASE do not waste your money/time on this course. The main issue is that other courses in the same specialization are very good but without passing this course, you can not earn specialization.

I took this course as part of "Big Data" specialization.
Unfortunately after taking break for half year the specialization changed and currently this course is not part of active "Big Data" specialization.
I cannot buy the complete specialization and cannot take single courses because specialization surprisingly can change so I prefer not to take more courses by this platform.

I was almost done with this course but I ended up finishing it. I have taken other courses on Coursera, and this one is the worst so far. You may get to know the basics of the Hadoop Platform but the lectures aren't much interesting and the lecturer reads the bullet points or a script. I was disappointed, frankly.

A bit more explanation along the slides would be really appreciated. Also it was a bit disappointing was the fact that the hands-on exercises were every word read from Cloudera, no addition/ additional information or clarification.

A walk-through of Cloudera's tutorials. Way overrated and over-hyped. Not worth the money.

The course starts to get weighed down by all of the material being shared, but just in the nick of time come the hands-on exercises. There are only a handful, and they come with pseudocode, so you aren't on an island, but they still add a ton of value because they put you in the driver's seat and get you thinking in terms of how you might solve a real-world problem in MapReduce or Spark.

Overall the course is very good. It helps you gain systematic knowledge on Hadoop and some very popular applications. But I have to say that the coding assignments are a little bit hard for those who don't have any programming experience. I would suggest add more hints in the assignments so that students do not need to put too much time researching about the basic syntax...

This course is very useful and provide technical insight about Hadoop and Spark framework architecture. This course teach you about what is big data and how to develop application using the Hadoop platform and I would like to recommend this course for those who want to become big data developer, this course is very helpful to start your career and understand the framework.

All the labs were really helpful in building the understanding of different applications. One area I felt could be helpful for labs is example of what output would look like at key intermediate steps. Writing up code stepwise and comparing results against some sample example would help as it would re-affirm the solution works as expected all the way through the exercise.

The course gave me an entry into Hadoop and Spark. I recommend revisiting the lectures and reading the forums if you get stuck. You will need a machine with enough RAM to run the Cloudera virtual box to do the programming assignments. I got stuck on a ubuntu 14.04 linux machine with only 8 gigs of ram but was able to run it on a iMac with 20 gigs of ram.

I did this course to get new knowledge about Big Data and better understand the technology and your practical applications.
The course was excellent and the classes well taught by the Teachers.
Congratulations to Coursera team and Teachers.

Great course. I really liked the lectures. They were quite information-filled, so I really needed to pay attention. But I think I learned a lot and got a lot out of the course after knowing nothing about Hadoop. You do really need to know Python beforehand. Writing out Map and Reduce tasks and Spark jobs is hard enough with the syntax.

I loved this course very much. The methodology used for teaching the students in order to build their basic concepts and basic understanding about the hadoop platform and application frameworks is astounding. I would like to thank all the instructors who guided and instructed throughout the course.
ThankYou so much.

This course was really good ..The exercises were just right, neither too tough nor very easy. However I personally feel that Spark section could be described a little more in detail. However, it doesn't take anything away from the course. A fantastic introduction to Big data tools with Hands on experience.

The best Hadoop introductory course on the market. Thankfully to the well structured course program it was easy to grasp all the Hadoop concepts with the reasonable time investment. The hands on assignment are challenging, but doable for anyone with no prior Hadoop or Python experience.

The concept given for HDFS write & read was ok. But it requires to elaborate on the Map Reduce flow from the memory & process side. But the thing I really liked is Spark. It really changed my vision towards Hadoop. With such an advancement Hadoop has become one of my favourite.

The course was amazing. I think this is the most appropriate course in this specialization. Other courses are also good but this one is different. This one was more about Big Data implementation, and was very good for students looking for development.
