---------------------------------------
Hi [[email protected]], for getting the totalLevels, spark cubing and
layered cubing are in different cases. Previously, there's a bug for spark
cubing, which has been fixed by
https://github.com/apache/kylin/commit/24042e2209d85b0c8de98a86d9a573aff182d9c9.
Let's me explain the details.

> Found two way of calculating the level of cuboids

> * via CuboidUtil.getLongestDepth(...)
> We should settle down on one approach.
