Subject [jira] [Commented] (HIVE-3323) Enable enum to string conversions
Date Tue, 14 Aug 2012 22:51:38 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13434607#comment-13434607

Travis Crawford commented on HIVE-3323:
---------------------------------------

Hey all, any chance I could get some feedback on this patch? Today we found another thrift-related
issue where a struct with no fields is not handled correctly (yes a bizarre field choice but
valid thrift). Fixing would depend on updating megastruct and its test (added here), and I'd
like to avoid piling more changes into this 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.
