Excellent overview of Spark, including exercises that solidify what you learn during the lectures. The development environment setup tutorials were also very helpful, as I had not yet worked with sbt.
The sessions where clearly explained and focused. Some of the exercises contained slightly confusing hints and information, but I'm sure those mistakes will be ironed out in future iterations. Thanks!

This is my first cource review on English, but I want to do accent on Heather's high professionalism, great explanations abilities and great organisation of material. I need to say that I have education of computer science teacher and I can say that it's wonderful cource. It was difficult for me and I've really increased my skill. Thanx.

As always, Coursera delivered another top quality courses on Spark with Scala. I have learned a lot of details, understood the underlying working principles of Spark in the last few days. Thanks to Dr. Miller for such a great course. I hope in the future versions of this course the overall presentations will be more smooth and typo-free.

this course help me form a basic understanding of Spark and how to use it to analyze large scale dataset. Besides fundamental knowledge of how to use, the lecturer also provide students with some deeper concept of how to optimize the performance of spark programming, which can be very useful in running code on large dataset.

Thank you Dr. Heather Miller and the EPFL team along with coursera team for this course. I found it interesting. It gave me complete insight of spark. I had a great start with spark.
The internal working of spark API, the shuffle operations, query optimization and many more tips are really useful. Thank you once again.

This course is a great introduction to Spark. The only thing I think could be improved is that each programming assignments has unit tests that drive students towards the final solution. I saw lots of people complaining in the forums about this slow and tedious back and forth of having the grader testing their code.

This course was by far the best of 22 courses I've done on Coursera. Prof Miller has this rare ability of presenting material in concise and interesting way and yet going into nitty gritty aspects when needed (in another course on Spark technology, such intricacies weren't covered). Thanks a lot for this course!

excellent introduction to Spark. I was always looking for some course which touches the underlying functional aspect of Spark then just showing syntactic values. Moreover this course also teaches how parallelism and distributed process works with Spark. You also get an idea why Spark is written in Scala.

I thought it was very good, hands on. I think they need to add a lesson 3 homework to bridge the gap between the lectures. Week 4 lecture is really long. The HW4 is a bit tricky and requires alot of research and lack of any provided unit tests makes it alot of work to figure out what is wrong.

This course is indeed introductive to learn all the necessary stuffs about Spark. It is pretty good to tell much about shuffling. Because we should not only be familiar with how to operate on Spark, but we should really have a good understanding of what's going on underneath the hood. Thanks!

It is a great course with excellent material.
There is a lot to try in this course, concepts that one has to try oneself which opens opportunities to learn.
Please go ahead with the course if you are starting to work on Scala and Spark. Iterations run great on a decent 8 GB 64 bit machine.
The information was explained really well for someone coming in with no spark and minimal scala knowledge. Due to this course I understood basic spark concepts well enough to begin understanding pipelines built on top of spark such as ADAM.
I would highly recommend this course to everyone.
By Edgar D•
Favorite so far out of the Scala Specialization Course. It was executed really well, and taught really well, too. Kinda wish they would add more exercises to help us get more experience with some of the concepts, but that's something you can always just do by yourself either way.

Excelente curso. Já trabalhei com Spark, mas tive a oportunidade de aprender muitas coisas novas sobre ele. Achei muito interessante a abordagem sobre as novas estruturas de dados que chegaram nas novas versões (para mim, pelo menos, pois trabalhei com a versão 1.6). Recomendo.
By Markus B•
Great course overall. The feedback on failed tests and out of memory errors on the assignments can be improved to make it more user-friendly.
Would be great to see a more advanced version of this course that dives deeper into the machine learning features of Spark, etc.
By Jaseer A•
Really enjoyed this course. Unlike previous courses where I had to wrestle with algorithms and only learn the subject as a side effect, the assignments in this course directly addressed the subject. One of the best in this series except for the first course in scala.
By Mugren A•
Perfect. One of the most summarized course, to the point, and straight forward without any trouble. Special thanks to Prof. Heather for focusing on the optimization part and performance and easily explained the lazy transformation and how it could highly cost us.
By Gustavo H L d S•
Such a great course! Prof. Miller gives a very good coverage about spark, it's perfect for beginners who never deal with his technology and advanced users who wants o refresh their knowledge about this subject. The didactic of teaching is also excellent!
By Šejla Č•
Brilliant lecturer and slides! The only problem is assignments not being clear on the expected outputs. Sometimes it takes more time to figure out what exactly is asked than to find the solution. A few more test cases or detailed examples would help.
By Kevin L•
I loved this course - it was a great introduction to Spark. At the end, I wasn't (and am still not) clear on type-safe operations on Datasets, and now to write Tests to verify this.
These will be one of the targets of my upcoming research and study.
By AJ C•
This course is a nice guided way to get started with Apache Spark! I wish I took this course earlier when i was using Spark at my previous company. It would've come in handy. Plenty of great content and the course exercises supply good practice.
By Abhishek K•
The course has a great content. The assignments are a bit tough for beginners but if you keep on trying, you will get some great insights of the technology. Also has the best and unique use case scenarios which keep questioning your knowledge.
By Dario G•
Lovely presentation of Apache Spark fundamentals using Scala. I believe that this course gives you enough background to do just about anything you want (as long as you have some familiar with Scala and SQL, and are willing to dig deeper).
This is the best content among the tutorials I've seen in Spark, the Prof. Heather maintains perfect balance between internals of spark and general usage. The examples given and assignments are realistic when compared word count problems.
By Dennis Y•
Thank the teacher, the course is very good, the teacher is also very nice. The first three weeks of feeling learned a lot of new knowledge, the last week may be each class time is relatively long. It would be better if you could split it.

Teacher has excellent teaching skills. She takes enough time to go through to concepts. Before introducing a new technique she teaches why the new technique is needed and explains how it solves existing problems. Absolutely great course.
