--------------------------------------
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.
