------------------------------------
HI, [~wheat9] If I understand you correctly, your meant currently the external
table source not implement both {{DefinedRowtimeAttribute}} and
{{DefinedProctimeAttribute}} interface. e.g: {{CsvTableSource}}, when we using
{{CsvTableSource}} by register {{registerExternalCatalog}},
{{FlinkLogicalTableSourceScan#deriveRowType}} will get None
{{XXXtimeAttribute}}. Please tell me if i understand you incorrectly.
And it's great if you can add test case for the error above.
Thanks,

> Project: Flink
> Issue Type: Bug
> Reporter: Haohui Mai
> Assignee: Haohui Mai
> Priority: Critical
>
> We observed that all streaming queries that refer to external tables fail
> when the Volcano planner converting {{LogicalTableScan}} to
> {{FlinkLogicalTableSourceScan}}:
> {noformat}
> Type mismatch:
> rowtype of new rel:
> RecordType(<table schema>, TIMESTAMP(3) NOT NULL proctime) NOT NULL
> rowtype of set:
> RecordType(<table schema>, ...) NOT NULL
> {noformat}
> Tables that are registered through
> {{StreamTableEnvironment#registerTableSource()}} do not suffer from this
> problem as {{StreamTableSourceTable}} adds the processing time / event time
> attribute automatically.
