Butao Zhang updated HIVE-28015:
-------------------------------
    Description: 
Some writer engines require primary keys on a table so that they can use them 
for writing equality deletes (only the PK cols are written to the eq-delete 
files).

Hive currently doesn't reject setting PKs for Iceberg tables, however, it just 
ignores them. This succeeds:
{code:java}
create table ice_pk (i int, j int, primary key(i)) stored by iceberg;
{code}
