Complete Hadoop Framework including kafka,spark and mongo db (Udemy.com)

I am so glad that I took this course, it was really helpful , great introduction to the tool and all the datawarehousing concepts, and I would like to review the content once again after having some more hands on experience on the tool itself. Instructor is highly experienced and highly capable of teaching what he knows.

This course is very helpful. Concepts are explained very clearly. Trainer made sure that underlying concepts of all the topics are demonstrated in detail. Hands on examples are also very handy. Once you publish videos for kafka and any other new topics please publish.

Worst course on Udemy. Instead of this you can read tutorialspoint.com and understand concepts clearly.In fact he has copied most of the content from this site. In many videos he tells this concept will be covered in next video but that next video never comes. Regretting by decision to buy this course. It was too late to ask for refund.

there is some audio issue with one chapter. Some chapters are not even there in course for instance, in kafka introduction, he says that in next class, he was going to explain the flow with example but there was no following chapter having this but instead, it went to Oozy. this is a beginner course for all of these components.

Discussed the topic very well and provided an example that helps me understand and appreciate how it works.

Spoken English needs to improve. Technical skills are good. However, ensure that you check what have you delivered in your previous lectures since you tend to repeat the same things again. But keep up the good work. I certainly learnt a lot.

The course content is very good. It will provide a good understanding. Presentation can be improved. The other reviews have highlighted the flaws quite well and I don't need to comment on that. I am more concerned about the knowledge.

Is interesting course with good information but also with some of videos that doesn't explain the correct behavior because lot of command fail and we don't see the correction or reason of failure. Some topics, more towards the end, are not sufficiently in-depth so less interesting.

Update: I have updated my rating with an increase because though the presentation is not enjoyable, but content is and I am learning from it. Very good for the beginner. Hope you polish it and add some more content on 1. Twitter setup with Flume 2. Kafka and Spark integration.

The instructor goes through the course just typing in example code or copy pasting it in without any explanation of the principles or concepts of the underlying technologies. There's no high level overviews, no reasoning behind which technologies make sense in different situations. It's literally just "type in this and this happens" which is a poor way to explain in my opinion.
