------------------------------------
Hi, [~t3hnar] thanks for your report. I get commit offset timed out error log
in 1.1.0 version. As commit offset timed may cause consuming duplicate
messages. Should this log be error level?
> 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
> Priority: Minor
>
> 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
