It's very hard to follow a bot's voice. Not at all interactive. A machine keeps speaking at a speed. That's not a way to learn something.

To me, this seems like general BS full of buzzwords, but you won't learn anything practical anout how to use these tools

Personally, I've found that the knowledge delivering method should be redone in a more attractive manner. Concretly, the fact of giving too many texts and theories in the slides easily make students get bored and lack of motivation to continue listening. For such kind hands-on courses, we need more and more practical exercises instead of too many theories lectures without showing any demo neither coding in the slides

IBM stopped to maintain/support it's platform where the jupyter exercises are hosted since more than 1 year !

It's a true shame, we discover at the end of the formation than it is impossible to finish it...

Too dry and technical plus I couldn't get some of the codes with the notebook to work. There is a better video especially for Hadoop on Udacity that gives a much better explanation and I do hope you try to make the material more digestable. Each video is trying so hard to cram as much information into it as possible without giving the students much time to understand what is going.

It is Presentation deck with AI bot giving Voiceover narration. No one really teaching anything .

It is a great course on the theory part but there is no practical part " I guess they was depending on the next course in the specialization", also it would be better for more non robotic way in delivering the lectures.

The worst course of this specialization by far. The lectures demanded a strong dev background, threw tech concepts in our face without caring no dev people would understand. The project was focused on data manipulation, joins/selects, without exploring the true potentials of Spark. Suggestions: applied study cases, real distributed dataset so we could test the different resources allocations, design and run a real spark environment with real data, not only csvs that fit in the computer memory.

To much concepts and theory, i need more practice examples and less theory concepts

All the thinks I need to know about Big Data, Spark, Hadoop and Hive and explained in details

Fantastic blend of theory and practical (labs). The labs are short and have concise material.

Since I already had a previous banckground using Spark this course refreshed the theoretical foundations about its main topics: RDD, parellelism amog other. It was good to remember the way Spark works. On the other hand I must say there are some troubles with some labs environments where is not possible to work on the practical exercises.

Good course on the theoretical concepts needed to understand these tools. However, there is not much practice.

No project. Labs are only copy-paste commands.

A lot of contents that are only explained using text (it will be nice if diagrams, images, examples are more used!)

In general, it's a OK course, with the following course it could be a overall good in order to start your Big Data Journey!

i feel, it should be good if they add more hands-on work for learning spark and Hadoop

Muy pocos ejemplos prácticos para comprender el funcionamiento. La teoría se podría aplicar con muchos casos prácticos fácilmente aplicable en los hands-on-lab como en otros cursos que he completado anteriormente.

I found this course very interesting, great for an aspiring data engineer! It starts by introducing the concept of big data in general and then goes into more and more detail, analyzing Hadoop and Spark in depth. I highly recommend it!

That is a well packaged course allow you crate bıg data applıcatıon. You can download as pdf files the application hands on practise and follow them and update them depending on ypur own appication

Solid and in-depth introduction to core elements of Spark. All you need to know on RDD, architecture, drivers and UI in one place!

A very very indepth couse by IBM. As someone who studies most courses on Coursera, I think IBM offers an in depth course so far

the lecture was clearly understandible and I feel very gratefull to have this lecture

thank you it was phenomenal😊

Course was full of information and details for a beginner In big data technology

well-structured course with comprehensive content and practical skills

good for new person who want to understand about hadoop and spark

leesons also the time i spend was unnoticable thank you so much
