> Key: FLINK-7221
> URL: https://issues.apache.org/jira/browse/FLINK-7221
> Project: Flink
> Issue Type: Bug
> Components: Batch Connectors and Input/Output Formats
> Affects Versions: 1.3.1
> Environment: Java 1.8.0_131, PostgreSQL driver 42.1.3
> Reporter: Ken Geis
> Assignee: Fabian Hueske

> I have a data set with ~17000 rows that I was trying to write to a PostgreSQL table that I did not (yet) have permission on. No data was loaded, and Flink did not report any problem outputting the data set. The only indication I found of my problem was in the PostgreSQL log.
> With the default parallelism (8) and the default batch interval (5000), my batches were ~2000 rows each, so they were never executed in {{JDBCOutputFormat.writeRecord(..)}}. {{JDBCOutputFormat.close()}} does a final call on {{upload.executeBatch()}}, but if there is a problem, it is logged at INFO level and not rethrown.
> If I decrease the batch interval to 100 or 1000, then an error is properly reported.
