The material has never been made easier to understand. I like how you introduce the concepts step by step and describe each process especially assessing the data so thoroughly and in an efficient way! Thank you!!
Brooooooo!! I was so confused before I found this video!!! Thanks!!! Your in-depth instructions allowed me to walk through this step by step and get things rolling!! I’m no longer confused!!
Thank you for the step-by-step walk-through regarding AWS IAM, not many easy-to-follow tutorial videos exist about this topic, glad to have come across this
Wow. I was really struggling with this but you explained it so clearly. Thank you, I really appreciate this video
THANK YOU, I’ve been struggling with the concept of spark but this video helped me understand it’s applicational value. I look forward to any upcoming videos !
Amazing explanation, straight to the point and very informative! It improved my understanding of the topic soooo much, thank you!!!
This it concise and covers a lot ground. Thank you so much for putting this together! Hats off to you my friend!
Holy cow, this is definitely the best explanation and hands-on examples out there, thanks!
Thanks for the great walk through! made it very easy to follow along and understand
Great explanation, have been struggling to understand how databricks and aws are connected .. this makes it clear ... thank you !
Excellent, clean and very easy guide! Helped a lot thanks Man!
Good stuff man! Really informative
Thank you for the detailed explanation. Really informative!!

Great video!
Great Video!
excellent tutorial!
Thanks for the information
Thanks!
I am confused at the part of adding json inline policy 12.41. How do I get this policy?
I could not find those features in databrick community edition. Is it a premium edition ?
Can you tell me, what issues you faced with EMR and why did you switch to data bricks? like the advantage of DataBricks over EMR??
Can anyone tell me where to get the sample data from?
If you’re struggling with finding the inline JSON policy, please use the link below and follow the steps: docs.databricks.com/administration-guide/account-api/iam-role.html#language-Databricks%C2%A0VPC scroll down, go to step #6, choose "Databricks VPC", then copy the code! Please don’t forget to like, sub, and leave a comment :).

@abdulzedan Thanks for the detailed setup video. After setting up and using the Databricks platform for almost a week now, I noticed that terminating cluster in databricks would also stop EC2 instance in AWS, but the NAT Gateway keeps running (hence incurring cost, if it runs for a month : 30days*24hours/day*0.045$/hr=32.4$ ). Since Databricks creates private subnet in 3 availability zone multiply that cost by 3. Is there a way to kill this NAT Gateway along with cluster termination? And spin it up when the cluster is restarted.

@@GohitBhat Thanks for the kind words! You're right in that when you terminate the cluster, you'll have incurring costs from the NAT gateways that are created on your behalf when you deploy your cluster. Because it's apart of AWS infrastructure, Databricks doesn't have permissions to delete this on your behalf. One suggestion would be to create a lambda function that checks whether or not a Databricks cluster has been terminated, and if so, deletes the NAT Gateways that were created upon creation of the clusters by DB.
am fro Azure background so this is very good sample video for me understanding from starting point regarding creating resources in AWS for Databricks etc...as I am moving towards AWS, Thank you! Do you have time for technical support, if someone needed, what is your personal contact info, can I have it?
I need some help pyspark, can you provide you availability and time ?
Commands written on notebook are hardly readable….seems good demo. I have set 1080 resolution.
Your code is impossible to see on my 1366 by 768 screen.
from where to copy the databricke VPC at JSON

In the Trust Relationships make sure you enter databricks aws ID not your AWS ID this line should be this - "AWS": "arn:aws:iam::414351767826:root"
