> In JdbcExportJob AVRO_COLUMN_TYPES_MAP is being set with the full schema of
> the output table. This causes the AvroExportMapper to fail with unknown
> fields if --columns was used to restrict the columns to export (it then tries
> to set a value on the generated class which doesn't exist).
> There are multiple ways I can see to solve this.
> * Filter the columnTypes passed on to the Mapper in
> JdbcExportJob.configureInputFormat
> * Pass the --columns value on to the AvroExportMapper and let it ignore
> things that are not in there
> * Let AvroExportMapper not fail when it can't set a field.
> I might be able to provide a patch and I'd go with the simplest (the first
> one probably) if there are no objections.
