Description

When using serde-reported schemas with the ThriftDeserializer, Enum fields are presented as struct<value:int>

Many users expect to work with the string values, which is both easier and more meaningful as the string value communicates what is represented.

Hive should provide a mechanism to optionally convert enum values to strings.
