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

             Summary: Change api.scala.DataStream to api.datastream.DataStream 
in HarnessTestBase
                 Key: FLINK-11222
                 URL: https://issues.apache.org/jira/browse/FLINK-11222
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: Hequn Cheng


Thanks to FLINK-11074, we can create harness tester from a DataStream which 
makes easier to write harness test.

However, it would be better if we change the parameter type from 
api.scala.DataStream to api.datastream.DataStream for the 
\{{createHarnessTester()}} method, so that both java.DataStream and 
scala.DataStream can use this method.
