All our other kafka 0.9 clients work fine with 0.10 brokers. But whenever I start a kafka-output logstash hangs, and can only be recovered with kill -9. Nothing in the logs. (Have not run with -debug yet.) kafka-input does not seem to have the same effect. But I don't really know if it's working at all as no input can send logs. ---

Just noticed that I have v 2.x of the plugins install. Seems I should have 3.x. Trying that now... Nope, same behavior with 3.x plugins. ---

But I do know the plugin is starting, from logstash.err: log4j:WARN No appenders could be found for logger (org.apache.kafka.clients.producer.ProducerConfig). log4j:WARN Please initialize the log4j system properly. log4j:WARN See [http://logging.apache.org/log4j/1.2/faq.html#noconfig](http://logging.apache.org/log4j/1.2/faq.html#noconfig) for more info. ---

The logstash team put together a nice compatibility matrix on the logstash plugin page > **[logstash-plugins/logstash-output-kafka](https://github.com/logstash-plugins/logstash-output-kafka)** > > logstash-output-kafka - Kafka Output for Logstash Do you see any connections from logstash to kafka when running something like netstat? ---

I had two problems, both user error. The first was the EC2 security groups did not allow egress to kafka. The second, I was using the docs released docs, not the master docs. It seems that 3.x has unified the plugin parameters between input and output. Just a few minutes ago we finished updating the production environment from rabbit to kafka and all is good. thanks! ---
