Example 91 with ExecutionEnvironment

use of org.apache.flink.api.java.ExecutionEnvironment in project flink by apache.

the class CoGroupOperatorTest method testCoGroupKeyFields2.

@Test(expected = InvalidProgramException.class)
public void testCoGroupKeyFields2() {
    final ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
    DataSet<Tuple5<Integer, Long, String, Long, Integer>> ds1 = env.fromCollection(emptyTupleData, tupleTypeInfo);
    DataSet<Tuple5<Integer, Long, String, Long, Integer>> ds2 = env.fromCollection(emptyTupleData, tupleTypeInfo);
    // should not work, incompatible cogroup key types
    ds1.coGroup(ds2).where(0).equalTo(2);
}
