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I was taking the course, the presenter was saying the year of the content, and it made me feel like the data could be outdated material, and as we know, talking about technical topics, it isn't good.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.

The course material is overall very good and easy to understand, although a bit abstract at certain points (mostly when it comes to technical things like what MapReduce consists of and what Programming Models are). Regardless, the instructors do a great job of explaining the concepts. Great course overall

Getting the right computer that can run the virtual machine is a must. After that, there were still all kinds of error messages due to various reasons. The discussion forum on this topic was helpful to a certain extent but can be improved. Running the virtual machine was quite straightforward after that

I loved this courses real life examples of the materials being discussed. It not only held my attention but also gave me a better understanding of how I might use it. The materials took what could be very complex realities and broke them down to 'bite size' pieces. OVERALL: GREAT COURSE FOR BEGINNERS.

it was my first experience of an online course . the course was very suitable for the beginners as describes and was very easy to learn . Just had a little problem in starting the cloudera virtual machine by following the given steps in the course . coursera is very good learning platform . Thank You.

I'm grateful to the instructor(s). However, when I turned on closed caption to get used to the accent, the CC text covered part of the slide information. Overall, this is a good course to take. I'm glad I took it. Also, I was hoping that there's a clear instruction of Cloudera Quick Start on Linux.

Overall the course was excellent.

A minor annoying issue was that the volume level is not constant between videos, so using earplugs was not an option, if you had the chance to take various lessons in a row.

In the end, I had to turn off the volume and use the subtitles instead, to avoid ear damage.

This is a great introduction to the concepts of Big Data. Compared to whats available online, this course does a great job of digging into the components and definition of big data vs just diving in with code examples. Well worth it for anyone trying to get a holistic understanding of big data.

It's good as an introductory course! A lot of topics are covered briefly and excellent examples are presented to help people understand the concepts! There is a need to update the "Hadoop hands-on training" examples as cloudera has stopped the support for virtual VMs mentioned in the course.

Fantastic course and all concepts were very well explained. Interesting quiz at end of every section that tests understanding of the topic and the glimpse of Hadoop in the final section is the best part of the entire course.

Hadoop fs -Thanks Ilkay Altintas and Amarnath Gupta :)

The content is good, however the presenters just read a text which makes it a bit boring to follow. Due to the style of presentation I find it rather distracting that the presenters are embedded in the presentation.

Further sources for additional reading would be great a well.

Great contents, and the way they explain them makes it easier to understand. If I had to mention an area, it would be to make the slides a bit more visual (the strong blue color sometimes made it more difficult to watch a few videos at a time). But overall great course!!

Dr Altintas is an excellent presenter and very thorough. I would have enjoyed more practical exercises instead of mainly theory videos. The ones done with Hadoop in the last week were very enjoyable. I also enjoyed Dr Gupta's videos as well. Excellent intro to Big Data.

I enjoyed this introductory course because it really provided the scope for this area of study and helped chart the course for the rest of the specialization as I move forward. Excited to move on through to the next course armed with what I have learned in this one!

Nice course with proper foundation of big data. Instructors were describing things nicely. It would be more better if you add some more reading material of each content so that something which is not described in detail then we can go through it. Thanks coursera.

Does a good job of providing foundational information about Big Data and the Hadoop ecosystem. The end of the course has a fairly easy hands on MapReduce exercise. I wish it had more exercises but I assume the other courses in the specialization would offer this.

El hecho de que mis compañeros revisen el trabajo de otros es muy poco objetivo, desde mi experiencia personal mandé un trabajo bien hecho que lo calificaron con un 40%, luego reenvié el mismo y obtuve un 100%, la calificación que merecía desde un inicio.
