> It seems that the FlinkKafkaConsumer is just logging the errors when trying to get the initial list of partitions for the topic, but its not failing.
> The following code ALWAYS runs, even if there is no broker or zookeeper running.
> {code}
>  def main(args: Array[String]) {
>     val env = StreamExecutionEnvironment.getExecutionEnvironment
>     val properties = new Properties()
>     properties.setProperty("bootstrap.servers", "localhost:9092")
>     properties.setProperty("zookeeper.connect", "localhost:2181")
>     properties.setProperty("group.id", "test")
>     val stream = env
>       .addSource(new FlinkKafkaConsumer082[String]("topic", new SimpleStringSchema(), properties))
>       .print
>     env.execute("Flink Kafka Example")
>   }
> {code}
> The runtime consumers are designed to idle when they have no partitions assigned, but there is no check that there are no partitions at all.
