Description

This command currently renames a directory under 1 table to be under another table's name space. This can't work for Acid since data itself has embedded transaction info.

If src is not full acid, it could be added to target side like Load Data - into delta/base, but if source side is also Acid the IDs won't make sense in target table. It could match if using global txn ids but may not match with per table write ids if some ID from src is committed but the same ID in target is aborted.

Does this command currently work with bucketed tables?
