      Description

      Hive currently supports merging small files with MR as the execution engine. There are options available for this, such as

      hive.merge.mapfiles
      hive.merge.mapredfiles
      

      Hive.merge.sparkfiles is already introduced in HIVE-7810. To make it work, we might need a little more research and design on this.
