Über den Kurs

Interested in increasing your knowledge of the Big Data landscape? This course is for those new to data science and interested in understanding why the Big Data Era has come to be. It is for those who want to become conversant with the terminology and the core concepts behind big data problems, applications, and systems. It is for those who want to start thinking about how Big Data might be useful in their business or career. It provides an introduction to one of the most common frameworks, Hadoop, that has made big data analysis easier and more accessible -- increasing the potential for data to transform our world! At the end of this course, you will be able to: * Describe the Big Data landscape including examples of real world big data problems including the three key sources of Big Data: people, organizations, and sensors. * Explain the V’s of Big Data (volume, velocity, variety, veracity, valence, and value) and why each impacts data collection, monitoring, storage, analysis and reporting. * Get value out of Big Data by using a 5-step process to structure your analysis. * Identify what are and what are not big data problems and be able to recast big data problems as data science questions. * Provide an explanation of the architectural components and programming models used for scalable big data analysis. * Summarize the features and value of core Hadoop stack components including the YARN resource and job management system, the HDFS file system and the MapReduce programming model. * Install and run a program using Hadoop! This course is for those new to data science. No prior programming experience is needed, although the ability to install applications and utilize a virtual machine is necessary to complete the hands-on assignments. Hardware Requirements: (A) Quad Core Processor (VT-x or AMD-V support recommended), 64-bit; (B) 8 GB RAM; (C) 20 GB disk free. How to find your hardware information: (Windows): Open System by clicking the Start button, right-clicking Computer, and then clicking Properties; (Mac): Open Overview by clicking on the Apple menu and clicking “About This Mac.” Most computers with 8 GB RAM purchased in the last 3 years will meet the minimum requirements.You will need a high speed internet connection because you will be downloading files up to 4 Gb in size. Software Requirements: This course relies on several open-source software tools, including Apache Hadoop. All required software can be downloaded and installed free of charge. Software requirements include: Windows 7+, Mac OS X 10.10+, Ubuntu 14.04+ or CentOS 6+ VirtualBox 5+....

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.

For a newcomer like me in this subject, it was an interesting learning, after this first course I am even more motivated to continue and to complete this specialization. As English is not my first language, I could still note some errors in the subtitle script.

I got difficulties with the last Quizz (the 2 questions on Hadoop) since the "out" directory already exist (created throughout the step by step videos and lectures) I could'nt process with the alice.txt question, the system can't overwrite the existing files and exixting directory. I had to delete first the out directory (thanks google with linux commands I don't know) with hadoop fs -rm -r out command. I had to repeat the same for the question #2 (Shakespeare text). Please udpate your instructions to clean the place prior to start an other exercice.

Thank you

I​ enjoyed the course very much, I think the start is very begginer friendly but by the end you increase the complexity of the material to make everyone more aware of various terms associated with Data processing, cloud computing, etc.

A​lthough the addition of hands-on Hadoop was good, I wish there were more assignments to review and put the knowledge into practice.

L​astly, there are a lot of questions in the quizzes that are a bit confusing to understand, especcially in the earlier modules. Additionally, it would be good to include explanations on why we are wrong for every question.

O​verall I feel like I learned a lot, but there are a few places that could be improved to make the course more engaging and accessible to everyone.

For an introduction class in Big Data this is excellent: concepts down to the point; good example analogies used; material provided to reinforce concepts and knowledge (transcripts, slides) were great. Videos were pretty good. Content of lessons are good; lab and software downloading/exercise with Hadoop give you a good sense of what expected in more advance classes.

I would add a bit more of information regarding to the downloading software and its purposes for those with no computing background (like what OS used when running the Hadoop... maybe I missed that?).

The class worth the money paid.

Overall an excellent introductory course. My only complaint were the practical exercise. Overall it was pretty simplistic which was fine but irequired understanding the syntax and of specific applications. That would be fine for introductory courses in those applications but I don't see the value in an introductory level course. Also, it was very difficult to download the virtual box application and get it to work. I don't see any value in going through that pain just to learn how to do a wordcount on the text of a book. I'd delete that exercise for this first course.

As an introductory course, it covers each and everything related to Big Data. But in my opinion, it's a theory-based course not much of lab works. Those who are looking for theory kind of stuff come to enroll this course. But if you are looking for practical usage it is not quite enough. Actually, it's my first course in Coursera so I enjoyed it a lot but first two weeks of this course are very much boring. Instructors repeat things over and over again. Overall, I thanks to the instructors to offer such a wonderful course. I am looking for further courses on this topic.

Overall quite ok. The presentation materials looked amateurish (the PowerPoint presentations). Some of the multiple choice questions were more word picking than actual checking your understanding of the topic. In the final Hadoop exercise I missed information how to set up the keyboard to German in the Cloudera setup. It took me over half an over to find how I can change my keyboard settings, otherwise I would have had a really hard time to finish the exercise because finding elements like "/" or ":" on a German keyboard with English settings is a chore.

It is a nice course, however I found my self struggling to find interest especially in the first 2 weeks. The problem is that during the first 2 weeks it is all theory and it is not as captivating as I would like. The third week is much better, especially when you get to install hadoop and try it a little bit. I would much prefer to get all the info for the big data as I progress with the specialization in order to find it interesting, instead of getting a big dose of it at the start of the specialization.

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.
