["Mark Wagner (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/AVRO-1228?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mark Wagner updated AVRO-1228:
------------------------------

    Attachment: TestEvolvedSchema.java

I'm getting different default value behaviors between Avro and Trevni (with this patch) when there are records with default values (whose fields may or may not have default values). I've attached a revised test demonstrating this.

> Giving AvroColumnReader an evolved schema (with a default value) to project down to causes a runtime exception, with a message of "No column named: *". As part of Trevni's support for Avro, additional columns should be given the default value.
