MapReduce Programming Model and Execution
MapReduce provides a programming model for processing large datasets across distributed clusters through two primary phases. The Map phase transforms input data into intermediate key-value pairs with each mapper processing a portion of input data independently. Shuffle and sort phase redistributes intermediate data grouping all values associated with the same key together. The Reduce phase aggregates values for each key producing final output. MapReduce framework handles job scheduling, task distribution, failure recovery, and data movement between phases.
Input splits determine how data divides among mappers with typical split size matching HDFS block size ensuring data locality where computation runs on nodes storing relevant data. Combiners perform local aggregation after map phase reducing data transfer during shuffle. Partitioners control how intermediate data is distributed among reducers enabling custom distribution strategies. Multiple reducers enable parallel aggregation improving job completion time.
