> ExecMapper is Hive's mapper implementation for MapReduce. Table rows are read by MR framework
and processed by method, which invokes Hive's map-side operator tree starting
from MapOperator. This task is to extract the map-side data processing offered by the operator
tree so that it can be used by other execution engine such as Spark. This is purely refactoring
the existing code.
