Arvin Zheng updated ORC-644:
----------------------------
Description: 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.
