Hadoop Administration: Online Hadoop Admin Training (Udemy.com)

yes the course is good and only thing is in some part video there is a some noise in sound.thats it than this the course is good

Describing the architecture is fine, but I guess there should be more points that can be share as some notes that can be remembered. Otherwise it would be good if we can save the videos once the course is over.

Excellent course and well explained by instructor

It's ok. As the audience are from different backgrounds, i suggest the following 1. Speak the new word less clearly. 2. Display the word on the screen. If someone didn't catch the word, they will find it on the screen. Make understanding better.

Introduction of Hadoop , what it is, why we use , who are all can learn and understand this ,like those who are having os knowledge or application knowledge, directly started the topic which is not good.

Good training, especially because of the focus on hands-on and examples, even building a cluster from scratch and turn it upside down several times, that's great, and thanks a lot. I just think it would be important to upgrade the contents to Hadoop v2, which has been around for a long time now, people are actually starting to look for Hadoop v3 upgrade nowadays, so Hadoop v1 is old. I also feel some parts of the explanation or details about configuration vs behavior (for instance, regarding timeouts/periods, purpose of the tasks, etc.) were not enough. Finally, I could not find the scripts being provided as part of the contents (I guess that's Udemy's fault, not the instructor's). I felt the last modules missed an explanation as to why we would do what we were doing before starting the steps, when an Admin would do them, etc. Important topics for Admins, like High-Availability, Tuning or Security would be great for the future. Good training overall and the instructor is very practical, experienced and delivers the information effectively and in short-enough sections. Thanks!

Informative however would like to see for hadoop 2.x . Plus do not see code and procedure used in the course in the resource section for the student to try later on their own

Content are good. User should use the terminal instead of VirtualBox. Sometimes it is hard to see and I have to come close to screen to see what is written. In the beginning , he had to elaborate all the .xml purposes, then start further.

You people were not interacting directly with the candidates. In this case the course is very poor and i too having a problem with software installation. After installation when I'm click on the reboot windows is not responding to the virtual machine. I'm not able to trace out the problem. so that I'm asking you to help me out of the this. Thank you, Regards K V R K Abhilash. kvrk.abhi@gmail.com

The course is just a shallow introduction and lacks the indepth explanation of concepts. I have also come across few incorrect explanations on some topics so far. Also as Hadoop 2.x is the new standard in Hadoop installations, this course sticks to the old version Hadoop 1.x which is a big negative. I wanted to learn YARN which is very important change in Hadoop 2.x.
