[FLINK-6040] [table] DataStreamUserDefinedFunctionITCase occasionally fails
Type: Bug
Priority: Major
Components: table, test
Problem Definition: DataStreamUserDefinedFunctionITCase occasionally fails
Design:
Three test cases in `DataStreamUserDefinedFunctionITCase` forgot to call
the method `StreamITCase.clear method`. This will cause the case occasionally
fails. Because the result of one case may affect another sometimes. The patch
the is simply adding the missing methods.
Impact Analysis:
Only the tests. No impacts on the core code.
Test:
Tested `DataStreamUserDefinedFunctionITCase` locally.
