Can I MERGE INTO ... INSERT with a column list in Hive? Here's a good example of a MERGE statement:

MERGE INTO target AS T 
USING source AS S
ON T.ID = S.ID and T.tran_time = S.tran_time 
WHEN MATCHED UPDATE SET quantity = S.quantity
WHEN MATCHED AND S.quantity IS NULL THEN DELETE
WHEN NOT MATCHED THEN INSERT VALUES (S.ID, S.quantity, S.tran_time);


When doing the INSERT, does it have to exactly match the structure of the target table, or can a column list be somehow be specified like in a simple INSERT statement? I don't like hard coding value lists that have to match the order of the columns in the table, I like my statements to be column order independent.
Every example I've seen includes all of the columns.  I also found this note about updates (though nothing specific to insert):


  Note that you cannot update only a part of a complex structure field. For example, suppose you have a structure stored as one field in a Hive table:
  {"name":"Johnson","surname":"Fall","age":23,"gender":"MALE"}
  You cannot update only the age field in the structure. You can only replace all values of the structure with new ones.
