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

             Summary: Add a string to the print method to identify output for DataStream
                 Key: FLINK-9850
                 URL: https://issues.apache.org/jira/browse/FLINK-9850
             Project: Flink
          Issue Type: New Feature
          Components: DataStream API
            Reporter: Hequn Cheng


The output of the print method of {[DataSet}} allows the user to supply a String to identify the output(see [FLINK-1486|https://issues.apache.org/jira/browse/FLINK-1486]). But {[DataStream}} doesn't support now. It is valuable to add this feature for {{DataStream}}
