Resolving this as duplicate of KAFKA-4764, KAFKA-5920
> Producer hangs on metadata fetch from broker in security authorization
> related failures and no meaningful exception is thrown
> -----------------------------------------------------------------------------------------------------------------------------
>
> 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.
