Hi, @fhueske , sorry for the late update for this PR. Codes have been
modified.
> 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: Improvement
> Components: Table API & SQL
> Reporter: Timo Walther
> Priority: Minor
>
> 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.
