Subject [jira] [Created] (KAFKA-7791) Not log retriable exceptions as errors
Date Mon, 07 Jan 2019 17:06:00 GMT
Yaroslav Klymko created KAFKA-7791:
--------------------------------------

             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
