Honestly, you are one of the best one that knows how to teach, because most of the video clips on KZbin have no idea of fundamental principles of teaching! Please do more of this kind of work especially in the area of massively confusing materials about Spark, we need people like you on KZbin. Thanks so much, and please let me know how to find more of the clips have you down so far. Unfortunately the link that you provided does not work and it is broken, would you please leave a connecting link to get in touch with you. Thanks

[@Raghav54321]

Could you please help me in below query. .suppose I need to create a application where I need to load multiple files (CSV) using DF , if any of the file structure ids different from our defined structure(we defined in beginning) then we need to redirect those files into some error folder and load the file only with correct structure..how will we achieve this in spark. Ex . file columns should be id,name,roll but in some files id,name,city,subject.. i need to load the files which are having id,name,roll columns only

What is RDD first ? You have explained how the data is stored in RDD but what is the architecture of RDD and why does we need that ?

Thanks for the explanation! Can a RDD be stored as a file or stored on a hard drive (and not just in a memory)? If yes, then a link towards an article describing it will be very helpful.

You should first explain what exactly RDD is rather than explaining how it is made and other things.Please clear the basics of the viewer first.Thank you :)
