PSpeaker who is a man is not very good communicating the lectures it's very difficutl to follow him as his tone is not very good for e-learning.

I enjoyed the practical introduction to Hadoop and Spark. I appreciated the quizzes, which exposed me to both platforms via hands on experience.

Challenging hands on experience working with both structured and unstructured data, and creating value out of it by using SPARK and MongoDB.

Content was good however we need to get more support on hands on as sometime we feel that we are stuck due to non availability of the right

Environment setup instructions for final assignment do not work as expected and need to be updated to avoid time spent in troubleshooting.

All of a sudden this course is enriched with hands on practice. I think it should be more improved as everything is not clear that much.

The final project is a bit tough but worth it. If you manage to finish it you'll have a new understanding of Spark RDDs and DataFrames.

Technical support for hands-on work is ridiculously out of date at the rare occasion it is available. and i’m paying for this course!

this course is great , its giving many hands-on sessions that allow the student to be on the way of being professional in this career

It is good course. Some instructions followed not working, course instructions and supplied resources requires update. thank you

Need more hands-on for final test, would really help to have extra two weeks split with just good handson. Before final test

More Hands on experience should be included.

Reading of Apache Spark documentation should be made mandatory for beginners.

The last quiz was very hard to complete. I didn't found enough content to solve que questions in the course material.

Need more explainaion. There are few videos such as that of RDD where I found difficulty in understanding the concept

The course is very instructive! however, I believe it should be updated (in terms of software version for cloudera)

Except for the exercise where it was frustrating to get the Spark Streaming to work, it was a very good learning.

Need a references for any one want to read more about each subject. I recommend have it at the end of each Week.

Helpful course to learn the basic components and processing on Apache Spark. Course quiz for MongoDB is great.

The assignments for Week6 was really tough, request to provide more hints or support in completing the same.

I learnt a lot in this course, but is hard. Many times the instructions in the assignments were not enough.

For better practice, more question sets should be provided apart from the quizzes that we already have.

course is very good. Excercises are very good. learnt alot about the mongodb and spark sql and RDD's

This is mre interesting than the previous courses on the Big Data Specialization. More hands on...

The most interesting part in this course dealing with spark and the final quiz is really amazing

that last spark exam was really hard. the script took a long time to finally get working
