Description

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
