Hi ?????? (1) Cube merging will merge the files under ??cube_statistics?? directory of the merging segments. (2) ??cube_statistics?? save the cube's estimated information(like cuboid rowcount, cuboid size), and it is used in many places, like spliting hbase region, estimating the partition num in spark cubing. So you'd better not delete it.
