----------------------------------------
Summary: Improve consumer group coordinator unavailable message
Key: KAFKA-10839
URL: https://issues.apache.org/jira/browse/KAFKA-10839
Project: Kafka
Issue Type: Improvement
Reporter: Lucas Bradstreet
When a consumer encounters an issue that triggers marking a coordinator as
unknown, the error message it prints does not give context about the error that
triggered it.
{noformat}
log.info("Group coordinator {} is unavailable or invalid, will attempt
rediscovery", this.coordinator);{noformat}
These may be triggered by response errors or the coordinator becoming
disconnected. We should improve this error message to make the cause clear.
