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!

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.

Slow videos repeating several times the same thing (not a pedagogical / "good to fix an idea" kind of repetition), which makes them hard to follow.
However the worst are the exercises: the first time after 3-4 other Coursera Scala related courses where I have to actively check the forums for minute details about what is expected / implied for the solutions to pass the grading.
Things like what to do when updating the kmeans and you have duplicates, subtle differences between average and mean, etc. ...
In all other courses the expectation of the exercises were sufficiently clear and straight forward that I never had to check the forums to solve them.
Also, the code style of the exercises is literally an anti-pattern in idiomatic Scala, against everything learnt in the previous Scala courses: "var" all over the place, low level loops like in C or Java, etc. ...

I don't know what happened but it seems they had technical or some other problem while preparing this course. Some assignments were more oriented to solving marginal problems then using Spark and distributed and parallel computing. And that is really annoying. Previous 3 courses were great, maybe this one will improve.

I can't give more than one star since the exercises contain too many mistakes, which are thoroughly discussed in the forums, have been acknowledged by the staff, and could be fixed in no time. As for the content I think it provides a good first overview.

good lectures another case of lectures not matching the assignment in terms of what you should pick up. inadequate resources and not enough depth on actual transformations and methods.

Material not updated and assignments quite confusing. Also lectures are too verbose and not to the point.

The assignments are very confusing and unexplained. They do not take long to reply to the forum.

The course is too basic.
