Jason Altekruse commented on DRILL-4056:
----------------------------------------
We've been having some weird issues with maven running out of permgen space
during the build. There isn't an error message in the snippet you posted, but
I'm guessing this is the issue.
Try increasing the permgen that maven will start up with by setting this
environment variable.
export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"
If you are on windows:
set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m

> Key: DRILL-4056
> URL: https://issues.apache.org/jira/browse/DRILL-4056
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - Other
> Affects Versions: 1.3.0
> Environment: Ubuntu 15.04 - Oracle Java
> Reporter: Stefán Baxter

> 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".
