             Summary: ExternalTableSource fails to add the processing time and the event time attribute in the row type
                 Key: FLINK-6780
                 URL: https://issues.apache.org/jira/browse/FLINK-6780
             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.
