Date Wed, 27 May 2015 14:16:17 GMT
Rico Bergmann created FLINK-2101:
------------------------------------

             Summary: Scheme Inference doesn't work for Tuple5
                 Key: FLINK-2101
                 URL: https://issues.apache.org/jira/browse/FLINK-2101
             Project: Flink
          Issue Type: Bug
          Components: Kafka Connector
    Affects Versions: master
            Reporter: Rico Bergmann


Calling addSink(new KafkaSink<Tuple5<String, String, String, Long, Double>>(
						"localhost:9092",
						"webtrends.ec1601",
						new Utils.TypeInformationSerializationSchema<Tuple5<String, String, String, Long,
Double>>(
								new Tuple5<String, String, String, Long, Double>(),
								env.getConfig())));

gives me an Exception stating, that the generic type infos are not given.

Exception in thread "main" org.apache.flink.api.common.functions.InvalidTypesException: Tuple
needs to be parameterized by using generics.
