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.
