all is great except the idea of struct function it is a little bit confusing .however all awesome hand-on practice please do more coursers

Interesting but no dept

This course is too short and too simple. I was expecting some details in Pyspark or mechanism in RDD. But nothing was shown but just some SQL operations.

Too easy for intermediate level.

This course has help equip me with a lot of experience on data analysis and i really love it. Thank you Ahmad Varasteh.

A big thanks to Coursera for creating such a wonderful opportunity.

Best guided project for an introduction to the PySpark

Excellent course and instructor.

Awesome course for beginners!

Good explaining

Great course

pretty good

Instructor is great but the project itself is very short and shallow. If you have no idea where to start - it's ok to start with this course, but if you already have little practice with pandas or want to know how to use PySpark in real HDFS environment - i'm afraid it wont be helpful.

Ok, but needs a longer explanation of the functions that are used and its range of possibilites.

The execution of this course is pretty good. But I wished the PySpark part was way bigger. It's basically a 3 minute introduction into PySpark and the rest done using Spark-like sql-queries.

This project is way too easy. Not tech enough to put on my resume. But may be a good intro of da and pyspark

The forms aren't maintained but its a good intro to pyspark - yet it doesn't include any theory.

The user interface is too clunky.
