the class OuterJoinITCase method testJoinWithAtomicType1.

@Test

    final ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
    DataSet<Tuple3<Integer, Long, String>> ds1 = CollectionDataSets.getSmall3TupleDataSet(env);
    DataSet<Integer> ds2 = env.fromElements(1, 2);
    DataSet<Tuple2<Tuple3<Integer, Long, String>, Integer>> joinDs = ds1.fullOuterJoin(ds2).where(0).equalTo("*").with(new ProjectBothFunction<Tuple3<Integer, Long, String>, Integer>()).returns(new GenericTypeInfo(Tuple2.class));
    List<Tuple2<Tuple3<Integer, Long, String>, Integer>> result = joinDs.collect();
    String expected = "(1,1,Hi),1\n" + "(2,2,Hello),2\n" + "(3,2,Hello world),null\n";
    compareResultAsTuples(result, expected);
