Subject Re: Understanding what happens when a job is submitted to a cluster
Date Thu, 13 May 2021 16:38:43 GMT
Thank you. This was helpful. I have follow up questions.

1. How does spark know the data size is 5 million?
2. Are there any books or documentation that takes one simple job and goes
deeper in terms of understanding what happens under the hood?
