How to coordinates distributed operations in Spark Core using SparkContext object

SparkContext Task

In Spark’s architecture, the SparkContext object connects your driver program to a Spark cluster, manages jobs, and hands out tasks to worker nodes.

It’s the primary object in Spark Core that allows your application to talk to the Spark cluster.

SparkContext Task

Connecting to the cluster manager (Standalone, YARN, Mesos, Kubernetes)

Coordinating executors and task scheduling

Creating RDDs from data sources or collections

Managing configuration and job execution

Providing access to services like the Hadoop FileSystem, broadcast variables, and accumulators.
