The data flow CDHWriteFileFromDB used for finalization is a non-resumable run, which for db sources happens when we use a table that doesn't have a primary key.  For non-resumable runs, we expect to almost always see duplicate results in case of node shutdown. We checked the generated table used by data flow during file template finalization and it doesn't have any primary key.

The HFix-B1887 will add primary key pyguid  in order to automatically add the primary key in auto-generated table as new file templates are created.
