Sergey Shelukhin commented on HIVE-14055:
-----------------------------------------
Hmm... the thing is that not being able to push down a filter is not an error,
it's an expected condition - most filters cannot be pushed down here, only a
narrow set of filters is supported. I could separate it into two functions, one
returning boolean, and the other non-nullable, but an exception shouldn't be
used in this case.
> directSql - getting the number of partitions is broken
