> 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.
