Hi all, I have a single node, multi (3) broker Zookeeper / Kafka setup. I am using the Kafka 0.10 Java client.
I wrote following simple remote (on a different Server than Kafka) Producer (in the code I replaced my public IP address with MYIP): Properties config = new Properties(); try { config.put(ProducerConfig.CLIENT_ID_CONFIG, InetAddress.getLocalHost().getHostName()); config.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "MYIP:9092, MYIP:9093, MYIP:9094"); config.put(ProducerConfig.ACKS_CONFIG, "all"); config.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer"); config.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.ByteArraySerializer"); producer = new KafkaProducer<String, byte[]>(config); Schema.Parser parser = new Schema.Parser(); schema = parser.parse(GATEWAY_SCHEMA); recordInjection = GenericAvroCodecs.toBinary(schema); GenericData.Record avroRecord = new GenericData.Record(schema); //Fill in avroRecord byte[] bytes = recordInjection.apply(avroRecord); Future<RecordMetadata> future = producer.send(new ProducerRecord<String, byte[]>(datasetId+"", "testKey", bytes)); RecordMetadata data = future.get(); } catch (Exception e) { e.printStackTrace(); } My server properties for the 3 brokers look like this (in the 3 different server properties files broker.id is 0, 1, 2 and listeners is PLAINTEXT://:9093, PLAINTEXT://:9093, PLAINTEXT://:9094 and host.name is 10.2.0.4, 10.2.0.5, 10.2.0.6). This is the first server properties file: broker.id=0 listeners=PLAINTEXT://:9092 num.network.threads=3 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 log.dirs=/tmp/kafka1-logs num.partitions=1 num.recovery.threads.per.data.dir=1 log.retention.hours=168 log.segment.bytes=1073741824 log.retention.check.interval.ms=300000 zookeeper.connect=localhost:2181 zookeeper.connection.timeout.ms=6000 host.name=10.2.0.4 When I execute the code, I get following exception: java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Batch containing 1 record(s) expired due to timeout while requesting metadata from brokers for 100101-0 at org.apache.kafka.clients.producer.internals.FutureRecordMetadata.valueOrError(FutureRecordMetadata.java:65) at org.apache.kafka.clients.producer.internals.FutureRecordMetadata.get(FutureRecordMetadata.java:52) at org.apache.kafka.clients.producer.internals.FutureRecordMetadata.get(FutureRecordMetadata.java:25) at com.nr.roles.gateway.GatewayManager.addTransaction(GatewayManager.java:212) at com.nr.roles.gateway.gw.service(gw.java:126) at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:821) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:583) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1158) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:511) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1090) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:109) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:119) at org.eclipse.jetty.server.Server.handle(Server.java:517) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:308) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:242) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:261) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:95) at org.eclipse.jetty.io.SelectChannelEndPoint$2.run(SelectChannelEndPoint.java:75) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.produceAndRun(ExecuteProduceConsume.java:213) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.run(ExecuteProduceConsume.java:147) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:654) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:572) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.kafka.common.errors.TimeoutException: Batch containing 1 record(s) expired due to timeout while requesting metadata from brokers for 100101-0 Does anyone know what I am missing? Any help would be appreciated. Thanks a lot Best, Armin Kadiyan
