I am writing a Flink Kafka integration program as below but getting timeout error for kafka :
import org.apache.flink.streaming.api.scala._
import org.apache.flink.streaming.connectors.kafka.{FlinkKafkaConsumer010,
FlinkKafkaProducer010}
import org.apache.flink.streaming.util.serialization.SimpleStringSchema
import java.util.Properties
object StreamKafkaProducer {
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("serializer.class", "kafka.serializer.StringEncoder")
val stream: DataStream[String] =env.fromElements(
("Adam"),
("Sarah"))
val kafkaProducer = new FlinkKafkaProducer010[String](
"localhost:9092",
"output",
new SimpleStringSchema
)
// write data into Kafka
stream.addSink(kafkaProducer)
env.execute("Flink kafka integration ")
}
}
From terminal I can see kafka and zookeeper are running but when I run above program from Intellij it is showing this error :
