Hadoop's Distributed File System is designed to reliably store very large files across machines in a large cluster. It is inspired by the Google File System. Hadoop DFS stores each file as a sequence of blocks, all blocks in a file except the last block are the same size. Blocks belonging to a file are replicated for fault tolerance.Powered by a free Atlassian Confluence Open Source Project License granted to Apache Software Foundation. Evaluate Confluence today .

This makes the actual reduce operation simple: the file is read sequentially and the values are passed to the reduce method with an iterator reading the input file until the next key value is encountered. See ReduceTask for details. At the end, the output will consist of one output file per executed reduce task.
