Facing error while running training example "writing to Apache Kafka" - apache-flink

Question

I copied the sample code from the hands-on examples of Apache Flink, and tried to get it run. The code is as following :
public class RideCleansing {
private static final String LOCAL_KAFKA_BROKER = "localhost:9092";
public static final String CLEANSED_RIDES_TOPIC = "mytopic";
public static void main(String[] args) throws Exception {
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
DataStream<TaxiRide> rides = env.addSource(new TaxiRideGenerator("C://data/nycTaxiRides.gz", 1000.0f));
DataStream<TaxiRide> filteredRides = rides.filter(new NYCFilter());
filteredRides.addSink(new FlinkKafkaProducer<>(LOCAL_KAFKA_BROKER,
CLEANSED_RIDES_TOPIC,
new TaxiRideSchema()));
env.execute("Taxi Ride Cleansing");
}
I have Apache Kafka installed and running locally. I get the following error!
Any help is appreciated!

I used either of the two followings dependencies for the Kafka connector.
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-kafka-0.9_2.11</artifactId> <version>1.0.0</version>
</dependency>
or
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-connector-kafka-0.10.2</artifactId> version>0.10.2</version>
</dependency>
