Edward Capriolo commented on HIVE-3163:
---------------------------------------
You know I am not sure exactly why/when this is true. I have a serde not hard
coded in serde-utils that does not require columns to be defined. But yes we
should get rid of the hard codes. (the class mentions something about
lazy-loading as well in the comments)
> enhance Deserialize to add a method to show whether the column names are
> derived from the Deserializer

> 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.
