Everything in this course is new to me, but it provides me with many practice so I can gradually get familiar with all these new stuff. I find it a bit challenging, but overall it's quite good.
The course takes you from basic level , step level .But It is quite fast for beginners , you may need pause video in between and try to understand the concept.

The main drawback of the course are the practical assignments. It was frequently unclear, what the requirements were and where to find materials mentioned in the assignments. You should also take into account, that 1) the main focus of the course is the hadoop streaming, 2) knowledge of docker is not a requirement for the course, but still is very useful

While the theory is great and the course is fully loaded with the information, the Spark grading is very buggy and unpredictable.
One of my solutions for Spark Twitter assignment was based on lookup() and every time I changed numPartitions, I had a new path sequence 😂
Due to problems with grader, I gave the course only 3 stars out of 5.

Learned a lot, but the videos alone aren't really enough to get you through the assignments. Also, the assignments have a 'bottleneck' at the grading system where you know the answer is correct yet the grader won't accept it because your route to the answer is different than standard.
The course content is good, but you will have a horrible time with the grader system. You will have to spend lot of additional hours which you shouldn't be. I could have learned a lot more if the assignments are clear and if the mentors are active. Many links are broken as well.

Although the faculties were knowledgable, it was very difficult to understand them sometimes. Also, the course is not up to date. The instructions given in the video to upload assignments was not matching to the ongoing scenario.

Practical tasks could use some work: it would not hurt to have more of them, but to improve them with good notebooks like Andrew NG's deep learning course (maybe not as simple as his, but mode informative for sure)

Quizzes in this course ask questions that are not covered in lectures. Subtitles are full of mistakes and typos. Other than that, the material of the course is very interesting.

Good (not excellent) as a technical presentations, but mediocre as a university class .
Clearly. done by an engineer, not a professional teacher
Great course but the assignments are a mess. The grader is unreliable and they are all sorts of problems. The content is great though.

Bad support, terrible problems with the UI, some homeworks are poorly explained. Nevertheless, the course's content is very good.

Good material, but very slow system for check hadoop and spark notebooks. I spent much more hours for complete practice tasks.

It's interesting course, but the loss of time due to incorrect operation of the task verification system is frustrating

Too advanced for beginners. Some working knowledge needed in big-data stream before starting this course.

The lectures are very fast and to me accent for some of the presenters are difficult to understand.
創建者 Papadopoulos K•
The subject is very interesting but the grading system is very problematic and difficult.
I can't say this is an easy-understanding course.
I have some knowledge on the Hadoop, MapReduce, and Spark. But the lectures in this course are not well organized and clearly presented. Many concepts are too abstract for people to digest and follow. They only talk about very limited theoretical knowledge, and the examples only mess up with your knowledge base.
Two points for the free access.

Material is good and detailed explanation.
I've faced an issue with Grader submission (not just me, everyone who was accessing Grader). I've tried to reach coursera team via Discussion forums, direct mail, contact-us portal. But coursera team asked me to wait for 7 days to get this fixed.
Issue was fixed after 7 days. So prepare to complete your Graders asap.

The content of course is quite good and I really appreciate the instructors taking time to prepare the videos. The grading system for the programming assignments is appalling though. Coding tasks are not hard, but hours are spent deciphering cryptic messages from the automatic grader and little feedback is provided for debugging.
