-----------------------------------

             Summary: Scala TypeAnalyzer does not consider ResultTypeQueryable
                 Key: FLINK-9556
                 URL: https://issues.apache.org/jira/browse/FLINK-9556
             Project: Flink
          Issue Type: Bug
          Components: Scala API
            Reporter: Timo Walther
            Assignee: Timo Walther


Scala's TypeAnalyzer does not consider the ResultTypeQueryable interface. This means that type information that has been specified manually is ignored in many cases.

For example:
{code}
val myConsumer: FlinkKafkaConsumer010[Row] = new FlinkKafkaConsumer010(topics, new MyDeserializationSchema(jsonSchema), properties)
 val inputStream: DataStream[Row] = env.addSource(myConsumer)
{code}

The row type is always generic even though a type information has been specified in the DeserializationSchema.
