Hadoop with MapReduce structure is being utilized as an option answer for investigating informational collections with tremendous size. However, Hadoop has demonstrated helpful for chipping away at colossal informational collections, its MapReduce structure is low level and it expects software engineers to compose custom projects which are difficult to keep up and reuse.
