> If the design for an existing cube is not good, which means its prebuilt cuboid set is not suitable for query, there should be a way to adjust this cuboid set. This is phase two of cube planner, also called cube optimization. Its data source should be base cuboid rather than the original data source, like hive, for the original one may be changed. Thus for cubing jobs, like cube optimization, we introduce a new input , base cuboid formatted by sequence file.
