Hello, The new producer org.apache.kafka.clients.producer.KafkaProducer seems to block on send calls when the cluster is unavailable.
How do I disable this and make send calls fast fail in the event of unavailable brokers? I know the 0.8.1 Scala-based producer did not block in that case. Regards, /David The polling errors I get periodically for each unavailable broker: <156>1 2015-07-31T07:12:22.026Z - Audit [ezakus@18060 level="WARN" logger="org.apache.kafka.common.network.Selector"] Error in I/O with stag-xxxx-002/xx.xxx.xx.xxx java.net.ConnectException: Connection refused at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:739) at org.apache.kafka.common.network.Selector.poll(Selector.java:238) at org.apache.kafka.clients.NetworkClient.poll(NetworkClient.java:192) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:191) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:122) at java.lang.Thread.run(Thread.java:745)
