Description

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.

java.lang.AssertionError: 
Expected :MutableList(Anna#44,1, Anna#44,2, Anna#44,Anna#44, Jack#22,1, Jack#22,2, Jack#22,Jack#22, John#19,1, John#19,2, John#19,John#19, nosharp,1, nosharp,2, nosharp,nosharp)
Actual   :MutableList(Anna#44,1, Anna#44,2, Anna#44,Anna#44, Jack#22,1, Jack#22,2, Jack#22,Jack#22, John#19,1, John#19,2, John#19,John#19, Miller,13.56, Smith,180.2, Williams,4.68, Williams,69.0, nosharp,1, nosharp,2, nosharp,nosharp)
