Sergio Peña commented on HIVE-14055:
------------------------------------
What about throwing a checked exception? I agree with you of invalid values. I
see that a NULL value can be returned in case the filter couldn't be formed
correctly. If NULL means an error, then a checked exception should be better
handled by developers, shouldn't it?
> directSql - getting the number of partitions is broken
