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

             Summary: DataStreamUserDefinedFunctionITCase occasionally fails
                 Key: FLINK-6040
                 URL: https://issues.apache.org/jira/browse/FLINK-6040
             Project: Flink
          Issue Type: Bug
            Reporter: Zhuoluo Yang
            Assignee: Zhuoluo Yang
            Priority: Trivial


Three test cases in DataStreamUserDefinedFunctionITCase forgot to call the StreamITCase.clear method. This will cause it occasionally fails. Because the result of one case may affect another sometimes.
