> ```
> ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
> DataSet<String> input = env.readTextFile(IN_FILE).name("source1");
> 			
> IterativeDataSet<String> iteration1 = input.iterate(100);
> IterativeDataSet<String> iteration2 = input.iterate(20);
> 		
> iteration1.closeWith(iteration2.map(new IdentityMapper<String>())).print();
> ```
> The code if wrong (closing iteration 1 with the step function of iteration 2), but it should not give the unsupported operation exception.
