> {{HdfsParquetScanner::ProcessFooter}} has an error message "File $0 has
> invalid file metadata at file offset $1." However, the value reported as
> "file offset" is an offset from the _end_ of the file, not from its
> _beginning_. This is very misleading, since without explicitly stating that
> the offset is from the end, it is usually understood to be counted from the
> beginning.
> Additionally, although the function name is clearly about a "footer", two
> comments explicitly mention processing the "header". This falsely suggests
> that metadata is at the beginning of the file, when in reality it is at the
> end.
