> Avro deserialization corrupts data
> ----------------------------------

> Key: DRILL-4056

> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Other
> Affects Versions: 1.3.0

> 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".
