Quizplus · Accepted Answer

The first step in MapReduce is the map step, which involves processing input data and converting it into key-value pairs. This is followed by the reduce step, which involves aggregating and combining the key-value pairs produced by the map step. Column and column family are concepts specific to columnar databases and not directly related to the MapReduce process.
