Learn By Example: Hadoop, MapReduce for Big Data problems (Udemy.com)

knowing about hadoop from basics is really good. This course seems to start from a very basic level where a layman can understand. Good explanation

This is the most detailed MR course I have come across anywhere. Coding along the course material will give anyone enough confidence to approach MR problems with great confidence. Kudos to the Loony Corn team.

Very well explained right from the scratch. If you're writing Hive queries not knowing how it works in the background this is a very good course to understand.

The visuals are very good and provide a very good explanation. Unfortunately, the speaker has a accent which makes hearing the lectures difficult. That can be seen when I turn on the closed captioning and the speaker's words do not translate well.

What an amazing course this is! No assumptions are made of the skill levels of the students. Core concepts are reiterated again and again throughout. Code is explained line by line. Clear graphics are used to demonstrate difficult concepts. Important information is always written out to facilitate the learning process. I cannot remember a course where I can recall concepts the way I can with this course. This course is above and beyond, bar none. Thanks Loony Corn!!!

The contents of the course are very good, diving deep into the MapReduce inner workings and with code examples ranging from the simple to the complex. However, the presenter's diction is, unfortunately, subpar, which can make it difficult to understand what is being said. Also, I believe the pacing to be too slow. I feel that sometimes there's too much redundancy in what's being said, which makes the lessons longer than they need to be. Still, for anyone trying to go beyond basic "Hello World" tutorials on MapReduce, I still recommend this course as a very good way to better understand and visualize the parallel concepts and its implementations in Hadoop.

I am loving the instructions so far. Installtion instructions were easy to follow so far, will leave complete rating later once the program is finished,

Course was pretty thorough and went through a fair bit of detail. Couple of things that could have made it better: 1. Reducing repetitions. A lot of the times concepts covered earlier were reviewed more than once. A simple link back to the appropriate section would have sufficed (eg on partitioning). 2. A few more examples on TotalOrderPartitioning could have helped. But other than that the course was great. Learnt a lot and hadoop and MR dont seem as daunting any more!

Course is very well-structured and quite good for a beginner in Hadoop. I haven't come across an online Hadoop course that has explanations so clear and concise. I am giving 4 stars instead of 5 because the team takes time to respond to queries and that may not be good for a beginner especially when stuck at some step during an installation or the execution of a job. Also, the instructors use Mac and if you are a windows user, you might need some additional steps or google searches to accomplish the tasks that are part of the course.

The material is great and really well explained. Coming from other object oriented prog language, I would love it to see the IDE setup and tips for using Eclipse or Intellij. the instructors are great at answering questions and providing additional resources.
