      Description

      ExecMapper is Hive's mapper implementation for MapReduce. Table rows are read by MR framework and processed by ExecMapper.map() 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.

        It seems it's easier to use ExecMapper directly than any refactoring. Postpone this item for now for later consideration.

        We have implement native HiveMapFunction instead of using ExecMapper directly in HIVE-7675, reopen this JIRA to track further refactoring.

        Since Hive on Spark doesn't use ExecMapper directly now, this is no longer an issue. Closed this for now.
