The Write Range Map stage takes any input in which at least one column is identified as Key.

It figures out the values of the key that give the most even spread of records when Range partitioning is used subsequently on the data, and writes these values into a file called the "range map" which is used by a later job that specifies the Range partitioning algorithm (based on the same key).
