MapReduce Model and Optimization for Parallel Efficiency and Network Utilization

Context

You are designing a large-scale batch processing job (e.g., feature extraction, log aggregation, joins) over a distributed file system. The job must scale across many machines while keeping both CPU and network well utilized.

Tasks

Explain the MapReduce programming model, including key stages (map, shuffle/sort, reduce), data partitioning, combiners, and fault tolerance.
Describe how you would optimize a MapReduce job for parallel-computation efficiency (task sizing, skew handling, locality, memory/IO).
Identify techniques to minimize network overhead and improve throughput when running large-scale parallel computations.
