list_bucket_dml seems to be a diff mismatch

The order of printing is different [466, 287, 82] vs [466, 82, 287] - possibly irrelevant
hash traversal order related.

> Some of the original "date" related functions return string values rather than Date values,
because they were created before the Date type existed in Hive. We can try to change these
to return Date in the 2.x line.
> Date values should be implicitly convertible to String.
