[jira] [Commented] (AVRO-1893) UUIDs are deserialized into Strings and not UUIDs

["Ryan Blue (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-1893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15406565#comment-15406565 ] 

Ryan Blue commented on AVRO-1893:
---------------------------------

It looks like you're using a different {{ReflectData}} instance to read and write. When you instantiate {{ReflectDatumReader}}, it uses {{ReflectData.get()}} but you've added the UUID type to {{ReflectData.AllowNulls.get()}}. You should use the same data model for both.

I also don't think it is a good idea to add conversions to the singleton instances of {{GenericData}} and subclasses, like {{ReflectData}}. If you want to change the conversions that are used, then I think the best practice is to create a new instance.

> Here is a test that shows UUIDs are deserialized back into a string instead of UUID.
> Applications would expect UUID fields in their objects instead of strings when avro reads them back.
