All others (outside/inside India) failed terribly to explain this concept. This guy has done it in 1 hour. My sincere thanks 🙏 to you. Please keep it up!
Secondary Name Node (SNN) in Hadoop takes snapshot of Name Node and is available for switchover in case of main Name Node failure. Manual switchover to SNN required.
it consist o a copy of all logs and files of name node so in case if primary name node fails , when there i a switch over they can access info from secondary name node...
I have spend 1 hour to listen this ..day before the final exam I really loved the way you explain ??.... It's makes me easy to understand!! During this pandamic situation we haven't listen classes properly...I am struggling a lot to understand... I feel really confident after watching this video Thank you so much...
Huge thanks for the knowledge the person has and the simplicity in which he explains complex concepts. Ignore the diction clearly English is not his 1st language. The simplicity in which he explains complex concepts is applaudable. Shout out to Sir Durga :) Keep it up.
RK sir you rock man. First time I understood something without watching another tutorial on same topic. I had one suggestion. If possible make links in the video that you can use to move back and forth to the key concepts. As an example if I want to listen about "input splits" again I can click the link to go to time 52:00 on the video for it. Thank you so much for a great tutorial.
The way Rama Krishna teaches is great! He explains the subject in a layman way which is well understood & clears the concept in the best possible way. Truly appreciated and thanks for sharing it online!!!
just paused my screen to pay bundle of thanks to you , you have explained all stuffs will relating to big data as i had miss my classes this semister , i was unaware of these contents and now because of you i have known big data analytics more than my other friends thankyou sir
Very clean explanation about hadoop filesystem architecture. Even a fresher can be confident to come into bigdata. Thank you Sir. Very Clearly explained.
WoW !! ... I am just new to Database world.... specially in Big data and Hadoop .... when i started to watch this video... i could not move for 1 hour as the way Sir explaining it i feel i am in my collage classroom and my favourite Teacher class is going on .... Really amazing ... The real time Example like Farmer and Platform Train which is Superb... !!!! Thank so much to explaining in such a simple Term..... will surely follow all your video.....
I agree with Sumit Sinha, He is an amazing teacher without a question. I did not even need to take notes, yet can explain this new skill to anyone. God Bless his knowledge. I hope he can up load some videos of Java Prog
This is the best video encountered so far in hadoop and hdfs . so clearly explained. hats off to you!! thankyou so much! and i m in love with that railway ticket example!
I always felt a nap when try to learn new things initially and even that things may be of my interest I felt boring. This is so because the presenter never or hardly explain what he/she wants to explain. This time I completed two consecutive sessions without a single nap and with all my interests and curiosity. I am sure if this video goes long for 4 hours in one go I, even in that case, would not leave it till end. Awesome !!
Feeling Proud When someone can teach technology like this, #ResectForSir. Sir the way you are understanding the technology is Remarkable. Thank you guys for this video. Sir you just made this technology interesting and fun while learning. Wishing you a good time. Appreciated Truly!!!
Great explanation of the core concepts of Hadoop. These are abstract concepts but you have made it really easy to understand with great examples and excellent illustrations. Keep it up!

really informative and useful video for hadoop beginners, the person can give an example only when the concept is completely known in and out , awesome.
thank you so much for opening up the brain and giving so much simple examples and making everything so easy, you are doing great, keep rocking and all the best
RK Sir...For me its too late to see this video. But its amazing one for beginners like me. You drag us into the concept with simple examples connected to nativity, agriculture and geography etc...So nice to see this video. You are an amazing teacher.
Sir your video is very ,very Good .Highly explainative and conscience at the same time. The Example that you provide are really good and easy to understand and map to Hadoop concepts. Thankyou for putting this up .
