new KafkaProducer hangs when no write permissions to topic

[Zhuo Liu <zz...@tigermail.auburn.edu>]

Hello everyone,


I am using 0.8.2 KafkaProducer in storm to publish to a topic.

I create with no write acls,

then use the new producer to try to publish and it will hang.


I guess we would expect some exception  instead.

Hey Zhuo,

I suspect the authorization errors are occurring when the producer tries to
fetch topic metadata. Since authorization wasn't supported in 0.8.2, it
probably ignores the errors silently and retries. I think this has been
fixed in the 0.9.0 branch if you want to give it a try.

Thanks,
Jason
