I really liked the course, it gave me head start on spark definitely there is much more to learn, nice intro course.

Very good course, it is a must for anyone who is starting in spark using scala, thanks a lot, it did really help me

Good course, it goes beyond functional algorithms and teaches also about how to improve performance of the cluster

Good course, shows a lot of useful and unobvious things about Spark. But not always has well described assignments

I learned a great deal about the Spark API. I recommend it to anybody eager to self educate after working hours.

This class is great! Highly recomended! It helped me to understand and perform better at my daily working tasks!

This course is awesome. I got a pretty good idea of spark. In fact this course helped me understand scala well.

This is my first completed course on Coursera! It's good for understanding Apache Spark's RDD and its usage.

I like the course tempo very much. It kept me away from doing anything else while listening to the lectures.

Great, short course, which gives great insight into Spark and ad-hoc data processing on Hadoop-ish clusters.

Very good course for a great start in Spark. Require some initial knowledge and coding experience in Scala.

Great subject, well explained with solid weekly assignments make this course a stellar learning experience.

Thank you for the great introduction in to the Spark, What it is and What are the most commonly used APIs.

Great Introduction to spark. Programming assignments helped me to improve my skills. Thank you very much.

Very nice explanation, trainer has good knowledge, course materials are good, video quality is too good.

Very nice in depth learnings. The teacher is very good and keeps the lessons short but still meaningful.

Thanks to this course I think that I have finally understood partitioning and everything about Datasets.

Excellent course!

Well-developed lectures and good-structured modules

With hands-on programming examples

It was well worth the wait! The instructor was good. Assignments were challenging as well as hands on!

It is an excellent course with good clear explanation of theoretical concepts and practical examples.

A very natural application of functional programming to real world distributed computation problems.

Brilliant intro to Spark. I really like the enthusiasm with which Heather explains the key concepts.

Course with excellent content, methodology and teacher. It was an extraordinary learning experience

Quite advanced; links seamlessly with the previous courses in the specialization. Very rewarding.

Wish we could have an in-depth spark class that cover spark streaming and structure streaming.
