>                 Key: KAFKA-5369
>                 URL: https://issues.apache.org/jira/browse/KAFKA-5369
>             Project: Kafka
>          Issue Type: Improvement
>          Components: consumer, producer 
>    Affects Versions: 0.10.0.0
>            Reporter: Koelli Mungee
>
> Debugging security related misconfigurations becomes painful since the only symptom is
a hang trying to fetch the metadata on the producer side
> at java.lang.Object.wait(Native Method) 
> at org.apache.kafka.clients.Metadata.awaitUpdate(Metadata.java:129) 
> at org.apache.kafka.clients.producer.KafkaProducer.waitOnMetadata(KafkaProducer.java:528)

> at org.apache.kafka.clients.producer.KafkaProducer.doSend(KafkaProducer.java:441) 
> at org.apache.kafka.clients.producer.KafkaProducer.send(KafkaProducer.java:430) 
> at org.apache.kafka.clients.producer.KafkaProducer.send(KafkaProducer.java:353)
> There are no meaningful errors on the broker side either. Enabling Djavax.net.debug=all
and/or Dsun.security.krb5.debug=true is an option, however this should be improved to get
a meaningful error.
