Nice video on laziness, type inferrence ... Good video.. I did not find any video that explains these finer details. I understand that there is a lot of hard work behind this... Good work.. congrats. I am waiting for more videos from you.

Honestly, I was watching another video on Spark but after switching to your video I could not go back to the other one. Your tutorial is very well explained. My doubts about RDD and Immutability are all cleared now.

Thank God for the other video on Spark - like Brian Clapper.  This video gave me a 4 aspirin headache - I gave up and watched the other ones.  Sorry for the dislike - but this guy is extremely hard to understand and follow.

Hey awesome video.. helped me to bridge the gaps in my understanding.. I hav a question for u.. if I have done rdd caching and my underneath data has changed say that it has appended few more rows.. then wat happens to my rdd in d cache?? Does it hav d old data or does it hav a mechanism to understand that data has changed n it has to also consider the new data..?!
Conventional wisdom says data in cache ll hav d same data as previous..!! Is it like d same..?
And of coarse, I've given a thumbs for this video...
