> Configuration is not passed to ORC's Reader.Option in OrcFileInputFormat which causes
someĀ [ORC configurations|https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/Reader.java#L170-L176]
to not be able to be picked up.
> Related issues:
> For example, the ORC upgrade in Hive 2.3.x changed schema evolution from positional to
column name matching. A backwards compatibility configuration "orc.force.positional.evolution"
could be set in ORC Reader.Options by [ORC-120|https://issues.apache.org/jira/browse/ORC-120]
however it could not be picked up resulting in null values when querying ORC tables where
the column names do not match.
