I love the course. It goes deep into the foundations, and then finishes up with an actual lab where you learn by practice. I greatly benefited from it and feel I have achieved a milestone in big data.

A step by step approach stating from basic big data concept extending to Hadoop framework and hands on mapping and simple MapReduce application development effort.\n\nVery smooth learning experience.

Overall it is a good course introducing Big Data concepts. However, there is no technical help on how to get the tools working. Some posts in the forums help. The course designers should mine the forums for problems and solutions and develop FAQs or technical tips for the tools. I had to change settings in windows control panel, app features based on a cryptic (but helpful) post and finally g

The course was very useful with what knowledge it provides. However, it would be better if there were more hands-on exercises on relevant stuff. The exercises are too easy and boring. Tougher exercises should be added and more time should be spent on the Hadoop Ecosystem part. Knowing the history helps but it should not replace more important topics.

A good introduction to big data (last time I was working with it was in the 1990s when a few 10s of MB was a huge dataset!). Slightly let down by the forums, despite loads of mentors there seems to be almost no presence of the teaching staff beyond setting up a few posts to spark discussion which in reality just prompt short responses and no replies.

Week 3 should have been broken down into at least 2 weeks and probably 3 weeks. We probably needed more guidance on using Hadoop as there were a lot of technical issues such as removing directories and local files that were not explained. It is easy to spend numerous hours running the same program over and over and not realizing the problem.

The installation part was tough and there were many issues with starting Virtual Box. Crossed each and every step by searching for the answers in discussion forms. Many are unanswered there so had to google extensively. Finally I am done with this course and I hope the rest of the courses are not so technically challenging.

Sometimes difficult to follow. I'm a computer person but the program discussed were completely new to me and I found I struggled with the material at some points. A lot of new terms as well but overall do-able. I feel like I learned something but not confidently enough to list any skills on a resume or anything like that.

The first week or so feels inconsistent and oversimplified. After that, when you get into the actual content, it gets much better. It then ends on a peer-graded assignment. While the assignment itself is creative and fun to complete, I've never been a fan of peer-graded assignments so early in an introductory course load.

The course is well structured with relevant theories & definitions. However, my opinion there was too much stress upon theory and less focus on practical. It didn't cover all possibilities where Hadoop Code might not run, given the fact that almost most of the learners were using Hadoop for the first time.

I little slow to start but the pace picks up nicely. Content is generally easy to follow. Some differences between spoken and voice recognition subtitled text. Practical tests were interesting but not particularly well explained for the MapReduce shapes task, which seemed to leave a few puzzled.

Bom curso, por ser um inicio ao haddop e nao informar que é direcionado para pessoas que tenham um conhecimento prévio, precisa procurar na internet comandos e dicas sobre como atuar em algumas situações que nao ão discutidas em aula, mas no geral material muito bom.

I believe this course can be performed much faster, beware that it is really an introduction, and IT professionals persons may feel it slow, in addition the presenter speaks English very slowly, good for non English proficient persons, but bad for the others.

Better content needed. While I understand this was an introductory course, it was challenging only in semantics (remembering exactly what subjective thing Ilkay mentioned/ selecting one of two partially correct options etc.) and not in concepts

Very informative, and I've learned a lot. But I felt it a little bit slow and boring. There are so many ways to make it so much interesting, and it's important too. I think that's why I took a long time to finish this course.

The course is nice for people without any background. With some background in physics/math/computer science it moves very slowly and doesn't provide much technical details. I wouldn't call it a specialization though.

Very Basic course. Don't expect in depth expectations. Inadequate hands on exercises in the course. You will get 10,000 ft view of Big Data after completing this course. Don't expect much from this course.

An introductory course that seems like it should have been the first week of a more in-depth course instead of being a stand-alone course. The cost vs benefit of this particular course is questionable.

The content is good, but the VM is bad, slow, and old version of everything. I have downloaded a Docker Container to continue with the program. They should update the VM or provide a Docker link.

I'm not sure who the target audience is for this course. The level of presentation seems rudimentary to me. I had a hard time sustaining interest in the course and did not finish.

The time / usefulness rate of this course is very low. Most of the stuff they teach (at least in introduction) is very basic theory that's presented in not really interesting way.

The course is a lot about talking and theory which is not very interesting. Final part of course is trying to work with hadoop using virtualbox and provided virtual image.

De momento he aprendido conceptos nuevos e interesantes, pero todavía no entiendo las herramientas utilizadas. Hadoop me parece muy confuso y dificil de utilizar

An amazing course to get a brief understading about Big Data, the course needs an improvement in the slides, and additional resources for better understading.

Very informative but the structure is a lecture where the concepts are basically read from a paragraph. Perhaps I'd give more stars if I only saw diagrams.

Was expecting more hands on stuffs, the class is too conceptual. The sound volume of the videos is not consistent, hope Coursera can improve a bit on this.

Interesting concepts and basics about Big Data. However, it could include more practical exercises or quiz to continuously learn and evaluate the student.
