Subject Producer connection unsucessfull
Date Fri, 05 Dec 2014 13:34:33 GMT
Hi,

I've installed the Hortonworks Sandbox and try to get into Kafka.

Unfortunately, even the simple tutorial does not work :(
http://kafka.apache.org/documentation.html#introduction

If I try to send a message via

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

I get

 ERROR Producer connection to localhost:9092 unsuccessful
(kafka.producer.SyncProducer)

java.net.ConnectException: Connection refused

        at kafka.producer.async.ProducerSendThread.processEvents(ProducerSendThread.scala:66)

In my server.properties the
host is set to host.name=sandbox.hortonworks.com, which is correct.

Thanks for any help,
Marco
