Point out the wrong statement.(a) The map function in Hadoop MapReduce

1.	Point out the wrong statement.(a) The map function in Hadoop MapReduce have the following general form:map:(K1, V1) -> list(K2, V2)(b) The reduce function in Hadoop MapReduce have the following general form: reduce: (K2, list(V2)) -> list(K3, V3)(c) MapReduce has a complex model of data processing: inputs and outputs for the map and reduce functions are key-value pairs(d) None of the mentionedI have been asked this question at a job interview.I'm obligated to ask this question of Data Flow topic in division HDFS – Hadoop Distributed File System of Hadoop
Answer» Correct option is (c) MapReduce has a COMPLEX MODEL of data processing: inputs and outputs for the MAP and reduce functions are key-value pairs Easy explanation: MapReduce is relatively SIMPLE model to implement in HADOOP.
