Review comment:
       Null order is not depending the setting `hive.default.nulls.last`:
   I tried to tackle this in #2227 but I experienced some regression in SMB joins: result
set mismatch because rows with nulls introduced.
   Let me check how was this handled prior this patch: I think the null order came from the
parent RS (which introduce the sort by ROWID) not the child (enforce bucketing + sort by ROWID).
