-----------------------------------

             Summary: Allow different field names for unionAll() in Table API
                 Key: FLINK-2985
                 URL: https://issues.apache.org/jira/browse/FLINK-2985
             Project: Flink
          Issue Type: Bug
          Components: Table API
            Reporter: Timo Walther
            Assignee: Timo Walther


The recently merged `unionAll` operator checks if the field names of the left and right side are equal. Actually, this is not necessary. The union operator in SQL checks only the types and uses the names of left side.
