Ismael Juma resolved KAFKA-4832.
--------------------------------
Resolution: Auto Closed
The Scala producers have been deprecated for a while and no further work is
planned. Please upgrade to the Java producer whenever possible.
> kafka producer send Async message to the wrong IP cannot to stop
> producer.close()

>
> Key: KAFKA-4832
> URL: https://issues.apache.org/jira/browse/KAFKA-4832
> Project: Kafka
> Issue Type: Bug
> Components: producer
> Affects Versions: 0.8.2.2
> Environment: JDK8 Eclipse Mars Win7
> Reporter: Wang Hong
>
> 1.When I tried to send msg by Async with wrong IP in loop 1400times 10batches.
> 2.I use javaapi.kafkaproducer designed by Factory.
> 3.1 of 10 batches I take Producer.Connected() and Producer.Closed().
> 4.I know I send msg to a wrong IP finally, But I noticed the terminal was
> blocking. It can't close normally.
> function just like that :
> public static void go(int s) throws Exception {
> KafkaService kf = new KafkaServiceImpl();//init properties
> for (int i = 0; i < 1400; i++) {
> String msg = "a b 0a b c d e 0a b c d e 0" + s + "--" +
> i;
> System.out.println(msg);
> kf.push(msg); //producer.send()
> }
> kf.closeProducerFactory();//producer.closed()
> System.out.println(s);
> Thread.sleep(1000);
> }
> kf.closeProducerFactory() is used by producer.closed(),
> But Async send was always waiting for kafka server .I gave it a wrong IP.
> I think it waits for long time Will bring problem with whole system.it occupy
> resources.
> And another problem was I sending kafka msg with true IP and Runnable
> ,Threadpools, all is right .Also use ↑ examples for loop.
> It take error that said wait for 3 tries.
> I also configered
> advertised.host.name=xxx.xxx.xxx.xxx
> advertised.port=9092
> Now I think it maybe cannot get so much concurrent volume in a time.
> Our System is over 1000tps.
> Thank you .
