-------------------------------
Somehow I believe this was fixed. Need to verify again on latest code.

> I got this error in a cube which has one fact table and one lookup table; All dimensions are normal, which looks be a very simple case (and the FK column does exist on rowkey descriptor), but I got this error on every query that uses columns on the lookup table; The error log is as below:

> Finally I found the data types of PK/FK column are different, one is varchar(6), the other is varchar(256); I changed them to be the same in hive, re-sync the metadata, then everything goes well.
>
> When I create the data model, Kylin Web GUI already detected this mismatch, and gave me an warning, but I choose to ignore it and move one. I think this check need be strengthened.
