Edward Capriolo commented on HIVE-3163:
---------------------------------------
I member looking at elephant bird aupport. Iirc it required the user to
generate an addition class . I took this approach because I wanted hive to work
with the protobuf class directly. I also figured that somehow the reflection
inspector would have something that did not work the way I wanted so coding the
entire piece from scratch was very attractive to me. If your data is in a
different format you can likely reuse almost all of the code, you just have to
customize the input format.
> enhance Deserialize to add a method to show whether the column names are

> URL: https://issues.apache.org/jira/browse/HIVE-3163
> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> 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.
