> I have an Avro file that support the following data/schema:
> {"field":"some", "classification":{"variant":"Gæst"}}
> When I select 10 rows from this file I get:
> +---------------------+
> |       EXPR$0        |
> +---------------------+
> | Gæst                |
> | Voksen              |
> | Voksen              |
> | Invitation KIF KBH  |
> | Invitation KIF KBH  |
> | Ordinarie pris KBH  |
> | Ordinarie pris KBH  |
> | Biljetter 200 krBH  |
> | Biljetter 200 krBH  |
> | Biljetter 200 krBH  |
> +---------------------+
> The bug is that the field values are incorrectly de-serialized and the value from the previous row is retained if the subsequent row is shorter.
> The sql query:
> "select s.classification.variant variant from dfs.<some> as s limit 10;"
> That way the  "Ordinarie pris" becomes "Ordinarie pris KBH" because the previous row had the value "Invitation KIF KBH".
