Hi Team,
I am trying with Kafka client on Windows 7 64bit -corporate pc which is backed
by proxy and Kafka is hosted in Ubuntu 12.04. This is my code:
Properties props = new Properties();
props.put("metadata.broker.list", "10.10.10.10:9092"); //Example IP
props.put("serializer.class", "kafka.serializer.StringEncoder");
props.put("request.required.acks", "1");
ProducerConfig config = new ProducerConfig(props);
Producer<String, String> producer = new Producer<String, String>(config);
But I am getting this error:
log4j:WARN No appenders could be found for logger
(kafka.utils.VerifiableProperties).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more
info.
Exception in thread "main" kafka.common.FailedToSendMessageException: Failed to
send messages after 3 tries.
