MapReduce Advanced allows efficient counting of the number of friends by parallelizing tasks across multiple nodes, where the Map phase assigns key-value pairs of users and friends, and the Reduce phase aggregates the total count for each user. This approach enables handling large-scale datasets by distributing computation, optimizing speed and scalability. Lion567
