Thank you for reporting, [~planka]. So, this is a bug only at ORC 1.7.0, right?

> ORC-577 introduced the ability to specify filters to allow row filtering.
> Schema evolution of a missing column is not handled leading to
>  {{java.lang.IllegalArgumentException: Filter could not find column with name:}}
> It is triggered in the following scenario:
>  * Read schema is supplied
>  * File schema is missing a column
>  * Provide a filter that uses that column during read
> The expectation is that the column is read as null and the filter applied on the read column.
