This paper address the how supplant MapReduce with Apache Spark as the default preparing for Hadoop.Apache Spark is superior to MapReduce towards leads issues and difficulties in taking care of Big Data with the target of giving an outline of the field, encouraging better arranging and administration of Enormous Information ventures ,larger amount reflection and speculation of MapReduce.
