@@backslash8874 brotha, it's just like 3 months internship wasn't that hard, my brother is the owner of the company so he just accepted to let me in. I was told to do a couple of work and understand d the concept first, I tried my best to go to internship coz I wanna become a senior like you. And see, that's the difference, I will introduce myself as a intern not a senior like you. 🤗🤗 I really admire you guys,🤗🤗 I waiting to finish my education and I wanna work! Infact I'm kinda girl who watches "the office"😂😂
Most excited video of 2023 for an diagrammatic representation and clear cut explanation ❤❤❤ really great. College staff wants people like you to teach.
The most complex name explained with the most simplest scenario. I understand this better now
The professors we want in Indian engineering colleges ❤
finally i know what is MapReduce, thanks !
Very clear and understanding explanation.
What a wonderful explanation!
What a quality sir, hand off
I watched many videos but your's 🔥🔥. I understood, thankyou!! 👏😊
this video made a complex topic in a very simpler way ♥️☺️💯
Thank you for this! I have a data engineering interview tomorrow and the example really helped me understand the concept well enough to be able to explain it myself if I am asked.

Very helpful. thank you:)
Best one I've seen yet
Amazing explanation!
Very nice explanation
Bro you are awesome 👍
This is what I wanted
Thank you for this super helpful video! What I have not understood yet is, how can I turn the process back? For example, if I am looking at the output file, how do I know in how many of those input files has the word 'apple' been? From what I understood, it could have been twice in the first (or second) file or once in each.
Excellent explanation
great vid. thanks
Tqsm ☺️
Great video! Now do spark!
the example is pretty straight forward
@ByteMonk dank video, very clear and concise but I've got a question: at 8:20 you say we're tasked with finding all the videos with a certain number of likes. Do we really need to go through ALL of the metadata if we're just looking for the condition "number of likes >= [some amount]"??
very good video
Thanks!

thank you so much, but maybe explain the example directly after the motivation next time.
Amazing explanation sir. Would like to know how FB store likes and comments. Suppose user from India likes a video, and another user from the USA likes the same video, are they stored in same place or in a sharded db (country wise), would like to know your perspective
Thanx 😊

Hadoop, in its original form, has reached a mature stage. It's less of a buzzword and more of a foundational technology upon which other systems are built. Many companies heavily invested in Hadoop infrastructure during its peak years and still rely on it. For example Yahoo! likely still has large-scale Hadoop systems for storage and batch processing. Facebook has also Built a huge Hadoop infrastructure for data warehousing and analytics. While they've moved a lot of processing to newer systems, legacy Hadoop clusters probably remain. These companies probably don't use Hadoop in exactly the same way they did during its peak. They likely have layered newer technologies like Spark or cloud-based analytics on top of their Hadoop foundations.
Excellent explanation!! Thank you.
