    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.
