> Currently, union operation is supported by DataSet/DataStream API, not available in Table API. To union two tables, user has to transform the parameter input to DataSet/DataStream, for example:
> {code:java}
> val unionDs = left.union(right.toDataSet[Row])
> {code}
> It should be more API friendly to user if add union operation to Table API, like:
> {code:java}
> val unionDs = left.union(right)
> {code}
