Hello, I am trying to use the new org.apache.kafka.clients.producer.KafkaProducer to take advantage of error reporting that is lacking in the current "stable" Scala client (import kafka.javaapi.producer.Producer). Two questions:
* I know that 0.8.2 is not yet released but is the new Producer feature-complete and ready for testing? * If so, how should I check for errors in KafkaProducer#send()? In my tests I brought down the Kafka sever and hoped to detect errors in the producer so that I could respond by re-queueing failed requests. However, I was not getting any exceptions on KafkaProducer#send(), instead I got an exception inside the producer Thread: WARN org.apache.kafka.common.network.Selector - Error in I/O with localhost.localdomain/127.0.0.1 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:232) at org.apache.kafka.clients.NetworkClient.poll(NetworkClient.java:178) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:175) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:115) at java.lang.Thread.run(Thread.java:744) Should this be bubbling up the the send() method, or should there be a getError() method in the RecordMetadata that is asynchronously returned? Basically, I don't understand the error-reporting API. Thanks, Steve Tarzia
