---------------------------------------

             Summary: add a backward compat option for external users to 
HIVE-11985
                 Key: HIVE-17731
                 URL: https://issues.apache.org/jira/browse/HIVE-17731
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


See HIVE-11985.
Some external callers (e.g. Presto) do not appear to process types from 
deserializer correctly, relying on DB types. Ideally, it should be resolved via 
HIVE-17714, hiding the custom SerDe logic from users.
For now we can add a backward compatibility config for such cases.
