Scala & Spark-Master Big Data with Scala and Spark - Spark Architecture

The video provides an overview of Spark architecture, focusing on the Spark context, driver node, and cluster manager. It explains how tasks are distributed among worker nodes and how data is communicated back to the Spark context for final output. The video aims to build understanding and interest in Spark's distributed behavior.

What happens to the output data after a worker node completes its task?

Explain the distributed behavior of Spark as mentioned in the overview.
