Min Zhou commented on TAJO-475:
-------------------------------
[~hyunsik] [~jihoonson]
Please notice that I add a verification in LogicalPlanVerifier.java.
Previously user can create partitioned table like this way
{noformat}
CREATE TABLE (foo int, bar string) PARTITION BY COLUMN( another_col int);
{noformat}
This verifier will forbid that kind of sql, because as an offline discussion
with Hyunsik. The partitioned condition will support expression as well.
Furthermore, only column partitioned table support virtual column. If we
continue to support hash/range/list partition, I think we should add this
verification.
