      Description

      Configuration is not passed to ORC's Reader.Option in OrcFileInputFormat which causes someĀ ORC configurations 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 however it could not be picked up resulting in null values when querying ORC tables where the column names do not match.
