> FieldParsers do not correctly set EMPT_COLUMN error state
> ---------------------------------------------------------
>
> Key: FLINK-8331
> URL: https://issues.apache.org/jira/browse/FLINK-8331
> Project: Flink
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.5.0, 1.4.1
> Reporter: Fabian Hueske
> Assignee: sunjincheng
>
> Some {{FieldParser}} do not correctly set the EMPTY_COLUMN error state if a
> field is empty.
> Instead, they try to parse the field value from an empty String which fails,
> e.g., in case of the {{DoubleParser}} with a {{NumberFormatException}}.
> The {{RowCsvInputFormat}} has a flag to interpret empty fields as {{null}}
> values. The implementation requires that all {{FieldParser}} correctly return
> the EMPTY_COLUMN error state in case of an empty field.
> Affected {{FieldParser}}:
> - BigDecParser
> - BigIntParser
> - DoubleParser
> - FloatParser
> - SqlDateParser
> - SqlTimeParser
> - SqlTimestampParser
