Hadoop Platform and Application Framework

I am enrolled and almost done with this course. I cannot wait to get done! I have taken many other courses on Coursera, and this one is the worst. I do not feel that it is giving me a true sense of what Hadoop or big data is all about, nor any "hands on" practice on applications to real world projects.
There is no feedback from instructors or mentors who normally respond to posts from other students requesting help or information. The only feedback seems to be from a few other interested students taking the course. And, most of the posts on the discussion board are outdated, giving the impression that there is no one else is taking the course.
The quizzes ask a student to "Choose all that apply". Most of the questions are in this format. I understand that an auto-grader usually does not give partial credit for partially correct answers, but there lies a huge disadvantage in even taking these quizzes if there is no feedback provided. Such is the case in the format of the quizzes for this course.
Additionally, the quizzes have nothing to do with the course content. I practically had to google every question to find out what I needed. You will learn more if you get a copy of the quizzes and research the answers for yourself.
Taking this course forced me to decipher through inaudible videos whose instructors mumble off of the bullet points in their slides. I have never given a Coursera course a bad review, but this one deserves it.

The Course videos are poor in content and in explaining what the tools do. The Quizzes ask questions that have not been covered in the video material and the programming assignments are in many cases unrelated to what is explained in the videos, instructions are unquestionably useless in many cases and you are expected to know how to to program. I can't quite understand how they would be so bold to say it is for business people (i.e. a high level course with minimal programming knowledge).
Certainly not worth the cost of the course. If I had not already paid for it I would drop and make better use of my time and money.
You are left to your own as the only help you get is that of other students and the posts they put. There is no way how to contact the instructors.

It's a joke of course. Take some other course not Coursera San Diego.
The course team DO NOT PUT any hours of EFFORT into developing the course. No material, not good examples, not good exercises. The The tech are exercises that later you realize they are in the hadoop platform.
The team is not involved at all in he discussions.
The assignments degree of difficulty/complexity are not related with the few "bla, bla, bla" they talk about in the course. So I had to spend many many many hours learning in internet what I had to know for completing the assignments. And of course because they did not answer to any of the students questions
The material offered for learning is no a joke is even worse.
I really recomend some other course not Coursera San Diego
