Actually, my prepareStatement queries works well with kylin version v2.0.
After I upgrade kylin to version v2.1, all queries have no results return,
Then I write test：
Return no results, and after that I change the query to statement
Finally, I got return values.
I have no idea whether it is a bug or I have done something wrong with upgrade?
As I have removed HBase tables “kylin_metadata_user” and “kylin_metadata_acl", I think
I can't come back to version v2.0 any more
I also try changed dependency kylin-jdbc to version 2.1.0 but help nothing.
