Detailed explanation-1: -MapReduce Algorithm Generally MapReduce paradigm is based on sending map-reduce programs to computers where the actual data resides. During a MapReduce job, Hadoop sends Map and Reduce tasks to appropriate servers in the cluster.
Detailed explanation-2: -The “MapReduce System” (also called “infrastructure” or “framework") orchestrates the processing by marshalling the distributed servers, running the various tasks in parallel, managing all communications and data transfers between the various parts of the system, and providing for redundancy and fault tolerance.
Detailed explanation-3: -With MapReduce, rather than sending data to where the application or logic resides, the logic is executed on the server where the data already resides, to expedite processing.
Detailed explanation-4: -Explanation: The reduce is the type of function which are responsible for consolidate the overall result that are technically produced by the map() function in the system.
