[jira] [Created] (KAFKA-3834) Consumer should not block in poll on coordinator discovery

Jason Gustafson created KAFKA-3834:
--------------------------------------

             Summary: Consumer should not block in poll on coordinator discovery
                 Key: KAFKA-3834
                 URL: https://issues.apache.org/jira/browse/KAFKA-3834
             Project: Kafka
          Issue Type: Improvement
          Components: consumer
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


Currently we block indefinitely in poll() when discovering the coordinator for the group. Instead, we can return an empty record set when the passed timeout expires. The downside is that it may obscure the underlying problem (which is usually misconfiguration), but users typically have to look at the logs to figure out the problem anyway.
