Description

When migrating a file written by pre-tlp ORC (before HIVE-4243) to a more modern ORC version, the file column names are breaking PPD by throwing

java.lang.IllegalArgumentException: Field tool_id not found in struct<_col0:bigint,_col1:bigint,_col2:timestamp,_col3:string,_col4:string,_col5:int,_col6:int,_col7:int,_col8:timestamp,_col9:string>

even though the Reader.Options has forcePositionalEvolution(true)
