[jira] [Updated] (ORC-644) nested struct evolution does not respect to orc.force.positional.evolution

     [ https://issues.apache.org/jira/browse/ORC-644?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Arvin Zheng updated ORC-644:
----------------------------
    Summary: nested struct evolution does not respect to orc.force.positional.evolution  (was: nested struct evaluation does not respect to orc.force.positional.evolution)

> 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: master
>            Reporter: Arvin Zheng
>            Priority: Major
>
> 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.
