What types of algorithms are difficult to express in MapReduce v1 (MRv1)?
A) Algorithms that require applying the same mathematical function to large numbers of individual binary records.
B) Relational operations on large amounts of structured and semi-structured data.
C) Algorithms that require global, sharing states.
D) Large-scale graph algorithms that require one-step link traversal.
E) Text analysis algorithms on large collections of unstructured text (e.g, Web crawls).

Question

MapReduce v1 is not well-suited for algorithms that require global state sharing because it is designed for parallel processing without shared state.
