Description

Problem from community user Sun:

Try to build our own test cube according to the offical tutorial. When
doing the step of Build Base Cuboid Data, error occurs.

I checked the mapreduce task log and found the following error stacktrace
:
Note that with defining measure step, I choose measure of GMV_MIN and
GMV_MAX both and these two measures are automatically defined as
decimal(19,4) and there is no way to modify that.

Super weird for this kind of exception info. Hope any experts can shed a
light on this.

Best regards,
Sun.
