[jira] [Created] (KAFKA-5369) Producer hangs on metadata fetch from
broker in security authorization related failures and no meaningful
exception is thrown
Koelli Mungee created KAFKA-5369:
------------------------------------
Summary: 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.
