Travis Crawford commented on HIVE-3323:
---------------------------------------
Hey all -
Feng and I looked at this today and decided we missed the nested map value case
because we didn't have a good way to test. We have an update (running CI now,
will post patch after it passes) that adds a new test struct that contains all
thrift data types, as well as some gnarly cases we found in real data (enum map
keys, enum map values, etc).
https://github.com/traviscrawford/hive/blob/HIVE-3323_enum_to_string/serde/if/test/megastruct.thrift
This new struct will allow us to test this and other thrift cases, such as how
binary data is not handled correctly (its interpreted as a ByteBuffer struct
instead of byte[]).
Will post what we believe is the last version of this patch after tests finish.

> URL: https://issues.apache.org/jira/browse/HIVE-3323
> Project: Hive
> Issue Type: Improvement
> Affects Versions: 0.10.0
> Reporter: Travis Crawford
> Assignee: Travis Crawford
> Attachments: HIVE-3323_enum_to_string.1.patch,
> HIVE-3323_enum_to_string.2.patch, HIVE-3323_enum_to_string.3.patch,
> HIVE-3323_enum_to_string.4.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.
