> When counting dimension number of aggregation group, the joint dimensions should be count as 1 instead of the real dimension numbers, which cause the exception below.
> java.lang.IllegalStateException: Aggregation group 0 has too many combinations, use 'mandatory'/'hierarchy'/'joint' to optimize; or update 'kylin.cube.aggrgroup.max.combination' to a bigger value.
