Example 21 with Meta

use of com.yahoo.bullet.result.Meta in project bullet-storm by yahoo.

Example 22 with Meta

use of com.yahoo.bullet.result.Meta in project bullet-storm by yahoo.

the class JoinBoltTest method testUnknownAggregation.

@Test

    // Lowercase "top" is not valid and will not be parsed since there is no enum for it
    // In this case aggregation type should be set to null and an error should be emitted
    Tuple query = TupleUtils.makeIDTuple(TupleClassifier.Type.QUERY_TUPLE, "42", "{\"aggregation\": {\"type\": \"garbage\"}}", EMPTY);

    BulletError expectedError = Aggregation.TYPE_NOT_SUPPORTED_ERROR;
    Meta expectedMetadata = Meta.of(expectedError);
    List<Object> expected = TupleUtils.makeTuple("42", Clip.of(expectedMetadata).asJSON(), FAILED).getValues();
    List<Object> actual = collector.getNthTupleEmittedTo(TopologyConstants.RESULT_STREAM, 1).get();
    Assert.assertTrue(isSameResult(actual, expected));
}

Example 23 with Meta

}

Example 24 with Meta

use of com.yahoo.bullet.result.Meta in project bullet-storm by yahoo.

the class JoinBoltTest method testUnhandledExceptionErrorEmitted.

@Test

    // An empty query should throw an null-pointer exception which should be caught in JoinBolt
    // and an error should be emitted
    Tuple query = TupleUtils.makeIDTuple(TupleClassifier.Type.QUERY_TUPLE, "42", "", EMPTY);
