Spark Architecture & RDD Basics

Level Intermediate to Advanced
Estimated Time ~2.5 Hours
Curriculum 6 Lessons
Course Mission

"Master Apache Spark's runtime cluster architecture — understanding Driver vs Executor JVMs, Client vs Cluster execution modes, and low-level Resilient Distributed Datasets (RDDs) with DAG lineage fault tolerance."


What You'll Master

Cluster Topology

Driver process coordination, Executor JVM worker pools, & Cluster Managers (YARN, K8s).

Execution Modes

Client Mode (edge-node interactive submission) vs Cluster Mode (production YARN execution).

RDD Lineage & DAGs

Immutability, lazy evaluation, & automatic partition recovery without data duplication.

Transformations & Actions

Narrow dependencies (map, filter) vs Wide dependencies (reduceByKey, groupByKey).


Learning Path & Course Syllabus

Driver vs Executor JVM processes, standalone/YARN/Kubernetes cluster managers, and Client vs Cluster deployment modes.

Low-level RDD core properties: immutability, partitioning, lazy evaluation, DAG graph lineage, and fault recovery.

Clickstream log dataset tracing through narrow transformations, wide shuffles, and driver action collections.

Scenario questions covering Driver OOM collect crashes, lineage fault tolerance, reduceByKey vs groupByKey shuffle boundaries, and Client vs Cluster modes.
