MapReduce is a distributed storage and processing framework in the Hadoop ecosystem that provides high-level abstractions for processing large datasets. It operates by breaking down tasks into smaller, manageable chunks that are distributed across a cluster of machines for parallel processing. Although MapReduce was one of the early frameworks in the Hadoop ecosystem, it's still widely used for batch processing tasks in big data applications.
