Travis Crawford updated HIVE-3323:
----------------------------------
Attachment: HIVE-3323_enum_to_string.5.patch
Ok, I believe this patch is complete.
Its interesting to see the megastruct serde-reported schema in the test output.
For example, binary is reported as:
my_binary
struct<hb:binary,offset:int,isreadonly:boolean,bigendian:boolean,nativebyteorder:boolean>
from deserializer
This is because its a HeapByteBuffer; we have a followup patch that fixes this
that can be submitted after this issue is resolved.
Also note how sets are structs with no fields.
my_stringset struct<> from deserializer
I'm not sure how to resolve this yet (turn them into lists?) but is an issue
that we now have visibility into.

> Issue Type: Improvement

> Reporter: Travis Crawford
> Assignee: Travis Crawford
> Attachments: HIVE-3323_enum_to_string.1.patch,

>
>
> 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.
