来自BIG DATA ANALYSIS: HIVE, SPARK SQL, DATAFRAMES AND GRAPHFRAMES的热门评论
content of the course is remarkable and the way they explained concepts is very lucid. I just want to give suggestions please give link to the data set they are using for illustrating the concepts.
Quite a good course, but weeks about graphs I found somewhat poor. Apart from that you learn basics of Hive, details of DataFrame API of Spark and how it internally works.
Unfortunately, I often spent more time trying to get my assignments to pass the automatic grader than on solving them. This made the course a bit frustrating at times.
I wish I could give more rating than 5 :). Excellent course. Thanks so much for such an excellent course. All the instructors are great.
