Zhong Yanghong updated KYLIN-2732:
----------------------------------
Description: 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. (was: 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

For cube optimization, cuboids to be pre-calculated need to be adjusted. During
this phase, there are three kinds of cuboids:
# cuboids to be kept
# cuboids to be removed
# cuboids to be added
The *cuboids to be added* can be derived from the base cuboid. Thus for cubing
job, we introduce a new input , base cuboid formatted by sequence file)
