Very interesting course. Explained concepts I'd heard of but didn't really know about. It is a foundation course for a specialization, it's not enough by itself but very good as a foundation course.

It is a comprehensive introduction to big data which covers significant components with enough content that can be absorb at this stage. A very good kick-start and excited for the next course ahead.

The course was awesome. It taught me the ins and outs of Big Data. Although its only the basics, I'd still recommend it to everyone before deciding whether you want to keep going as a Big Data specialist or not.
Some steps are not uptodate e.g. hadoop and wordcount aren't in the same folder as listed by this course. They were in the other folder /usr/lib... . It'd be nice if you guys put a "find" command with that description, because I've had to search it myself. That's why I took one star out of it.

Excellent course. Well presented and very informational. A very good first course to get introduced to this topic. The quality of the presenters is outstanding.
My only feedback for improvement would be that some (very few) questions/answers in the assessments were possibly somewhat unclear as did not directly related to presentation contents. Therefore it was more difficult to understand what was required.
But otherwise everything was clear and useful.

This is very good course. It help you to understand the importance of Big Data, especial how nowadays big companies can take advantage of their large data storage to came out with lot of stuff like: innovation, user experience improvement. Big Data is also useful for organization. This course let me discover how Big Data is being user in US for social purpose. Mostly, I also learn technical skill with Hadoop which is a Widely user Big Data framework.

It was a very nice introductory course, and I'm looking forward to the future modules! As the lectures in this particular module are very verbose, I would've liked occasional in-lecture quizzes (not marked, of course) to keep me more engaged as there is a lot of factual information to assimilate. Prof. Daphne Koller does this during her PGM lectures and I found such quizzes very beneficial in keeping me in sync with what she's talking about.

Overall a good introduction to Big Data. Needed no prior experience, but ironically I found I'd misunderstood the way Map:Reduce worked. Reading around afterwards I worked out exactly how it worked, but I didn't think it was explained very well. Overall though, a great intro into a subject which is highly hyped in the IT industry, and demystifies some of the concepts, explaining what Big Data is good for, and hinting at it's limitations.

It's not easy to understand all the concepts and definitions. The questions and quiz are a little abstract. For example, the task for mapreduce algorithem is absolutely inconvenient. Preparing the Hadoop environment is a very time-consuming job. It would be better to find a way for the learners to easily understand everything and not just physically memorize them. And a clould environment with Hadoop preinstalled would be a good idea.

This course is a really good introduction to Big Data. I come from an EE background and barely have any experience in IT/CS field. I was able to adapt and get a really good introduction to the Big Data world. My favorite part of the course is Hands On exercises at the end and quiz based on the hands-on exercise that provides you experience with Cloudera, Hadoop and MapReduce. I enjoyed this course and would recommend this course.

This is an excellent introductory course on Big Data in general and introduce to basic usage of Hadoop using Cloudera on a virtual machine. This course could be improved further especially to working professionals by spreading the course over 4 - 6 weeks instead as the 3 weeks duration is very short as the coverage of this course is quite broad. Thank you to the course instructors for preparing this wonderful course.

Overall information on Big Data. I enjoyed the course though it could be refreshed. Short introduction and then straight o Hadoop, it would be good to have some helicopter view on different possibilities application wise and then I will say more practical uses of Hadoop. The tasks were great althou I would love to see it gets more tricky. Some more difficult guided task, to deliver actual insights would be great.

The Cloudera Hands-On demo was good, but a bit outdated and it could've been longer than introducing to wordcount or wordmedian. Perhaps, that's as simple as it gets. But maybe that's enough for an intro. It'd be nice to know how to take the foundations from this course to the next level with a related course or one with more advanced topics particularly one with challenges encountered in industry.

good overview on Big Data. I like the intoroduction to Hadoop using the Cloudera VM, that's where things start to be more quantitative than qualitattive , some parts of the lectures could be improved. Also would be nice to be able to download the entire scripts for the lectures as a pdf at the end of each lecture or each week rather than only having it as a .txt file per lecture.

Some of final lab instructions were out dated, i.e. the jar file was not in the directory listed. Perhaps too much time was spent on covering the introductory material. It could have been better with more actual examples and/or talking more about determining whether a data set would be a candidate for using Hadoop.
I enjoyed the class and look forward to the next course.

The course in general is good and useful. However, there are a few caveats here and there. For instance, sometimes the questions in the quizes are not comprehensible. Maybe this is the problem of English proficiency for teaching. Also some case-studies can be added to the assignments and course. To train our eyes to figure out various data sources, and potential values.

I usually do not provide bad review if I get to learn. But the problem with this course is a lot of outdated applications (i.e., old virtual box installation, cloudera old version which is no longer supported so you need to use an alternative bitnami vm or such). This course needs to be updated (or maybe I started this too late). Either an annoying experience.

Great course for those new to big data - it helps you understand the core components and processes of big data analytics. As a heads up, the last assignment will require significant computer bandwidth to support the program needed. Overall, very useful, understandable course on a topic that is becoming a foundation for business, society, and government.

I can't give the 5th star because of the hands on exercises that are frozen in time. First, with Windows 10 and 11 we have Hyper-V and the course only provides Oracle VMs that are incompatible with Hyper-V. Than, the exercises are in Python 2, and in 2022 it's dead and most of the things we can't make them work because there isn't support for that.

Last assignment is hard to understand. You should included a proper direction in how your clear your "out" directory when trying to solve the question. I had to search for quite some time on other sites before I understood how I could create a new folder/directory and run the query from there. Other than that, great introduction to a new field!

I learned some new things because I'm a total beginner,I think the contents are updated but not very structured,the hands-on part is just a small peek of the whole big data process system and not very useful.It's not a complete course if you don't take the later courses of the whole specialization.So I gave 4 stars for this introduction course.

It's starts slow, building a foundation for people who are completely new to the subject, but by the end, I felt I got a lot from the course. I wish there was a hands-on assignment the first week. Also, it's too bad there wasn't much conversation in the forum. The questions posed between videos were interesting and deserved more attention.

Lorsque je me suis inscrit sur ce cours je ne le pensais pas ainsi, je l'ai sous estime les outils que vous mettez à notre disposition sont de hautes factures et les cours sont très attractifs. Si j'ai donné 4 étoiles au lieu de 5 c'est parce que la transcription en Français n'existe pas encore et c'est un embattant pour les francophones.

This course has been a wonderful start of this journey. Looks like I am glued to Coursera due to these courses. Paucity of time, good/comprehensive material and other reasons had kept me from proceeding forward till I found this material. Thanks to the two professors and apt material that they have created, this seems to be taking off.

Good Course. But Lecturers read from the notes. Which removes the human element and sometimes seems too robotic. They should try to bring the person more to the course by not reading and making it more interesting to hear what they are saying. I think the human element was missing but content of the course was very good.

The content of the course was great, however, it was made several years ago and it needs to be updated. While I was taking the course, the presenter was saying the year of the content, and it made me feel like the data could be outdated material, and as we know, talking about technical topics, it isn't good.

I'm new to the subject. Content is appropriate for my experience, but it bugs me the poor design and presentation of the course. Activities are ok, but more hands-on exercises, or written tasks will definitely help increase understanding. Overall, course is a good introduction, and It can be completed quickly

I keep wondering when the lectures were recorded and which years data refer to. I do not think that we see 2018 numbers here. In a field such rapidly evolving like BD data and information referring to 2016 or even 2015 is outdated. @Coursera team: Can you please timestamp the videos and the data presented.
