             Summary: Support automatic type conversion (or fail) when using 
struct_in with different types
                 Key: HIVE-14134
                 URL: https://issues.apache.org/jira/browse/HIVE-14134
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin


E.g. if the struct in int and double, this should work or fail to compile: 

{noformat}
select * from test_4 where struct(`my_bigint`, `my_double`)
IN (struct(1L, "a", 1.5BD), ...)
{noformat}

Right now in vectorization it all depends on serialization format so it doesn't 
work; in non-vector it also doesn't work for some other reason. See HIVE-13945
