I think you can improve this video by actually demoing the application and walking through each step. I am new and I got almost no understanding after finishing watching it once, and then I watched other videos and came back to this it made a little sense only then.. I hope I make sense..?

its showing connection refuse error while creating the sparksession
great effort. I believe you are technically very sound but little more improve in teaching in explaining the concepts, it is like you are reading a PPT.
On the 2nd line of code, I am getting message: ModuleNotFoundError: No module named 'pyspark'
Could you please make sure you have pyspark package installed through the anaconda command prompt and please let me know?
