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

             Summary: enhance Deserialize to add a method to show whether the 
column names are derived from the Deserializer 
                 Key: HIVE-3163
                 URL: https://issues.apache.org/jira/browse/HIVE-3163
             Project: Hive
          Issue Type: Bug
            Reporter: Namit Jain


There are some serdes: ThriftDeserializer and AvroDeserilizer which 
contain the column information. I mean, the user does not need to specify the
column schema.

Currently, this information is hard-coded. SerDeUtils has a method to get this
information from the name of the serde.

Ideally, Deserializer should be extended to add this method.
