Most likely the Kafka jars are in the wrong spot. Whats the path that are they extracted to? Was you logstash built with the make file or manually?

Installation mode: Manual Kafka jars are at: /home/abacus/kafka/logstash-1.4.0/vendor/jar/kafka_2.8.0-0.8.1

joekiller commented 10 years ago

Make sure the jars are in /home/abacus/kafka/logstash-1.4.0/vendor/jar/kafka_2.8.0-0.8.1/libs instead of just /home/abacus/kafka/logstash-1.4.0/vendor/jar/kafka_2.8.0-0.8.1

I think you are missing the libs directory. It needs to be relative to this include https://github.com/joekiller/logstash-kafka/blob/master/lib/logstash/outputs/kafka.rb#L18

/home/abacus/kafka/logstash-1.4.0/vendor/jar/kafka_2.8.0-0.8.1/libs Worked for me!!

Thanks mate for such a great tool.
