Dongjoon Hyun resolved ORC-644.
-------------------------------
Resolution: Fixed
> nested struct evolution does not respect to orc.force.positional.evolution
> --------------------------------------------------------------------------
>
> Key: ORC-644
> URL: https://issues.apache.org/jira/browse/ORC-644
> Project: ORC
> Issue Type: Bug
> Components: Java
> Affects Versions: 1.5.10, 1.6.3, 1.7.0
> Reporter: Arvin Zheng
> Assignee: Arvin Zheng
> Priority: Major
> Fix For: 1.7.0, 1.6.4, 1.5.11
>
>
> I noticed that even when orc.force.positional.evolution is set to true, the
> nested Struct evolution is still Hive field name based, which caused some of
> our queries to return incorrect values for fields inside a nested Struct
> since our Hive column name does not match to ORC column name.
