> Per the Javadocs for ResultSetMetaData#getColumnTypeName():
> "type name used by the database. If the column type is a user-defined type, then a fully-qualified
type name is returned."
> Hive's type for array, struct and map is not String. It is array, struct or map, using
a JSON string serialization. Returning the Hive type here will allow you to programmatically
determine if you should parse the value in the ResultSet as JSON.
> ResultSetMetaData#getColumnType() should potentially return OTHER to indicate the column
is a database-specific return type.
> This would replace the fix provided HIVE-1378.
