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

Owen O'Malley resolved ORC-644.
-------------------------------
    Fix Version/s: 1.7.0
                   1.6.4
                   1.5.11
       Resolution: Fixed

Thank you for the added test cases! Since ORC-626 came in first, I went with their configuration knob. Your tests cases also called out that the handling for arrays was wrong with ORC-626.

> 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.
