Kursteilnehmer-Bewertung und -Feedback für Introduction to Big Data von University of California San Diego

very boring

The initial presentation is a bit bloated, naming all the ways big data can be useful could have been 5 minutes. The default configuration of oracle VB and cloudera quickstart did not work for me at all (windows 7 64bit, 32g of ram), I had so many issues that I spent much more time trying to get that to work than I did everything else in this class. Finally, the course at no point mentioned any of the potential social/legal issues of using dig data, just what the value of tracking information. I have done a few certificates from either EDX or Coursera, and this was the worst one.

These UCSD "big data" course series is not great. I am pretty sure the "instructors" are reading straight from a public wiki. The dropping of acronyms and buzz words indicates the instructors are not familiar with the core content nor able to actually instruct. Glossing over actual execution and installation of sample virtual machines is abhorrent and completely ruins what minimal value a student may have learned. There are many free YouTube videos on Hadoop that are more informative than this course series.

I found this course mostly vague and the videos highly redundant and unorganized into a useful building of knowledge. This quizzes were hard but not because the material is difficult, but only because it quizzed you on subjective things the lecturer said instead of objective big data knowledge. Only useful thing I took away from this courses was a general view of the Zoo and the cloudera install. I think this course can be combined with the second course int he specialization and then cleaned up.

this course is really all about theory. Initially i liked the course but then i realised instructor is just reading a book instead of explaining the topics practically. I wont reccommend this course if you want to learn it practially. I suggest dont buy course in first glance, first go with the audit mode and see if you really liked the content or not.

Unable to download and install cloudera vm instructions. Even after putting the request in discussion forum and flagging the assignment with details to issue. There is no assistance. Wasted so much time and unable to complete the course . Can't move forward to next step. There should be a message center to connect with instructors.

The Hadoop assignment is a disaster. Cloudera VM didn't work and there was no help in the forum. I needed to workaround the last assignment so that I finally can move on after two days trying. I hope the next courses in this specialization will be better.

Please update this course or delete it completly

The course do not have technical support when practicing with HADOOP or installing the Virtual Machine. This is supposed to be for Marketing Managers too who are not engineers or Informatic experts in this issue. We pay for having support not for reading slices from 10 years ago!!!!!

Most of the information is useless, there spent two weeks talking about how you should manage your data that is something you can find anywhere in the internet. The only useful thing are the videos about Hadoop in the last week.

No peers are available to grade assignments. My credit card was dinged because no one grade my assignment within the 7 days, so the course was incomplete. To top it off, most of the labs don't work, and run on an obsolete VPS.

Very disappointing. Poorly written quizes and presentations. The level of the course is far too basic to be of value, but is required for the specialization. Why not offer an option to test out of basic introduction courses?

The bad things: Way too basic and outdated. The first 2 weeks of the course had no value to me.

The good things: It is an online course so easy to speed through first 2 weeks. Intro to mapreduce and exercise in week 3 was good.

Honestly, for the price paid, the value given is quite low. I expected to have more hands-on working with the Hadoop ecosystem rather than this course's focus on background that really does not help one to become productive.

I don't need this course, and I'm trying to unenroll bc I'm already doing a certification that is better suited to my goals, I hate seeing this on my list of courses!! I will not finish it, please remove it!!

Too many things I already know and which are quite obvious, when you have some little computer science knowledge, less practical information; the explanations for installing Cloudera etc are insufficient!!!

Very basic. All this information of this course can be self taught by Googling and the hands on exercise at the end of the course is a joke. For the $59 price of the course, expected more.

Presenter is very bad lecturer. She seems to be reading (badly) from a tele prompt, rather than lecturing. The quality of the slides is very poor. Not the level of a reputable University.

The lectures are just not very good. Terms are confused. Just not that good. The material is not difficult at all, it is just the lectures and slides are poor.

Last exercise is half the course and took many frustrating hours to install and for me never worked. No support provided by instructors. You are on your own.

Shallow. Perhaps useful for a student of management to skim over, but there is nothing that a student with technical background would gain from this course.

Instructors have very good knowledge but courseis very very theoretical with less examples and your subconscious mind is not even listening tovideo.

Everything at high level, people have to imagine things to really understand what is being said. Seriously has to work on the deliverable and plan.

THIS COURSE IS COMPLETELY USELESS FOR STUDENTS WITHOUT HIGH END INFRASTRUCTURE AS THEIR ARE NO CLOUD LABS FOR PRACTICING THE IMPLEMENTATION.

I cannot complete the course due to installations problem of the software required even if I have all the requirements needed on my laptop.

Very bad course. The lecturors are not talking in a greenhand-friendly way. I cannot understand anything after I took the entire course.
