Hi,

I am using Logstash **5.3.0**.

When I use Kafka output plugin in my config file as follows:  
output {  
kafka {  
codec =\> plain {  
format =\> "%{message}"  
}  
bootstrap\_servers =\> "dev02n.wh:9092"  
topic\_id =\> "hdfs\_audit\_log\_test"  
retries =\> 3  
batch\_size =\> 3  
client\_id =\> "hdp-nn-audit"  
}  
}

I get the following warnings:

```
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 for more info.

```

I do not receive any messages in the intended Kafka topic and I guess the reason is probably because that log4j is not setup properly.

What am I missing here?

my kafka version is 0.9. Java version 1.8.

downgrading the logstash to 2.3 solved the problem.

No, that's not likely.
