I'm enjoying the course.

The lecture quality is not satisfactory.

It helps a lot.

You explained Hadoop very well. Thank you for the great lecture~

It was a good lecture on the basic concepts of Hadoop.

It is very good for learning Hadoop basics, installation methods, and environment configuration. It is a lecture that organizes basic MapReduce development in Python and Java step by step, so it is easy to follow and less burdensome. However, since the instructor lives abroad, the native pronunciation is somewhat difficult to hear, and some terms do not match the Korean pronunciation, so it can be confusing (Maven: Maven, Cobic: Covid) And the word order in which it is explained is often unfamiliar, with the subject coming last, so it can be difficult to understand what is being explained. ex) A is B and C and has D characteristics -> A with D characteristics of B and C (I think this is probably because Koreans are not familiar with English word order) Excluding these parts, I recommend it to those who are just starting out with Hadoop basics.

The lessons are easy to understand.

It seems like a good start for beginners. Since it only has Hadoop, I hope you think about it before purchasing. However, I think it is very attractive to proceed only with Hadoop without something like Cloudera.

Instructor, thank you so much for providing such a high-quality lecture at such a low price! I am a new data engineer, and I was considering a thick book while thinking about how to start with big data frameworks such as Hadoop and Spark, and I came across this lecture that I had purchased in the past. I have never used Java before, so it will take some time to understand, but I will complete it well! You said you are planning a Spark lecture at the end of this year or early next year, so I am really, really looking forward to it! Please, I hope that this lecture can be explained as easily as this one based on pyspark!

It was a lecture that helped me understand the overall system of Hadoop. Thank you~^^
