liyang commented on KYLIN-2718:
-------------------------------
I see the introduction of a log of the combination... which makes things
complicated. Concerning it is really an edge case, I don't feel it worth that
complexity. Why don't we just detect the long overflows and throw an exception
or cap at Long.MAX_VALUE?
Just want to keep things as simple as possible.
