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

             Summary: CsvTableSource.getDataSet() expects Java ExecutionEnvironment
                 Key: FLINK-4247
                 URL: https://issues.apache.org/jira/browse/FLINK-4247
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
    Affects Versions: 1.1.0
            Reporter: Till Rohrmann
            Priority: Minor


The Table API offers the {{CsvTableSource}} which can be used with the Java and Scala API. However, if used with the Scala API where on has obtained a {{scala.api.ExecutionEnvironment}} there is a problem with the {{CsvTableSource.getDataSet}} method. The method expects a {{java.api.ExecutionEnvironment}} to extract the underlying {{DataSet}}. Additionally it returns a {{java.api.DataSet}} instead of a {{scala.api.DataSet}}. I think we should also offer a Scala API specific CsvTableSource which works with the respective Scala counterparts.
