Review Comment:
@kovjanos try below scenario:
````
create table target (a int, b int) partitioned by (p int, q int) clustered
by (a) into 2 buckets stored as orc TBLPROPERTIES ('transactional'='true');
insert into target partition(p,q) values (1,2,1,2), (3,4,1,2), (5,6,1,3),
(7,8,2,2);
create table source (a int, b int, p int, q int);
insert into source values (9,10,1,2), (11,12,1,3), (5,13,1,3);
merge into target t using source s on t.a=s.a
when matched then update set b=s.b
when not matched then insert values(s.a, s.b, s.p, s.q);
