In the earlier video, you said that when any action is performed the data goes to the driver but in this video, you are saying the data goes to DAG Scheduler. Can you please explain this?
You said "DAG helps to achieve fault tolerance. Thus we can recover the lost data". It is true, but it is kinda referring mapreduce does not have fault-tolerance. MapReduce has fault tolerance as well.
Thanku Sir🙏

Driver has lots of components under the hood. DAG scheduler is one of them.
