Our logs are being flooded with this message from the producer since we updated
the broker to 0.9. I was hoping somebody could review this PR to see if it is
an acceptable solution to the problem.

> This can be reproduced successfully by doing the following :
> * Start a 0.8.2 producer connected to the 0.9 broker
> * Wait 15 minutes, exactly
> * See the error in the producer logs.
> Oddly, this also shows up in an active producer but after 10 minutes of
> activity.

[jira] [Created] (KAFKA-3112) One incorrect bootstrap server will prevent Kafka producer from opening
Jonathan Bond created KAFKA-3112: Summary: One incorrect bootstrap server will prevent Kafka producer from opening Key: KAFKA-3112 URL: https://issues.apache.org/jira/browse/KAFKA-3112 Project: Kafka Issue Type: Bug Components: clients Affects Versions: 0.8.2.1 Reporter: Jonathan Bond Priority: Critical If any of the servers specified in bootstrap.servers are not resolvable through DNS the configuration is taken as an error, and the client won't start up. We pass in 30 possible servers, and one had an issue so the client wouldn't start. It would be better if the client will attempt to start if there is at least one server available from DNS. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
