--------------------------------------
Summary: Not log retriable exceptions as errors
Key: KAFKA-7791
URL: https://issues.apache.org/jira/browse/KAFKA-7791
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 2.1.0
Reporter: Yaroslav Klymko
Background: I've spotted tons of kafka related errors in logs, after
investigation I found out that those are harmless as being retried.
Hence I propose to not log retriable exceptions as errors.
Examples of what I've see in logs:
* Offset commit failed on partition .. at offset ..: The request timed out.
* Offset commit failed on partition .. at offset ..: The coordinator is
loading and hence can't process requests.
* Offset commit failed on partition .. at offset ..: This is not the correct
coordinator.
* Offset commit failed on partition .. at offset ..: This server does not host
this topic-partition.
Here is attempt to fix this: https://github.com/apache/kafka/pull/5904
