[jira] [Created] (KAFKA-10808) Improve LogCleaner logs

Omnia Ibrahim created KAFKA-10808:
-------------------------------------

             Summary: Improve LogCleaner logs
                 Key: KAFKA-10808
                 URL: https://issues.apache.org/jira/browse/KAFKA-10808
             Project: Kafka
          Issue Type: Improvement
          Components: log cleaner
    Affects Versions: 2.4.1
            Reporter: Omnia Ibrahim
            Assignee: Omnia Ibrahim


When LogCleaner take long time to clean, it doesn't give enough clues for us to know if it's taking long time because it's not working at all or is it slow because of the partition that it is cleaning right now, which make troubleshooting bit tricky, for example, when LogCleaner take long time to clean or keep retrying it doesn't log anything to address the following

- which topic partition causing the LogCleaner to grow the I/O Buffer
- what is the reason to grow the I/O Buffer

It would be nice to add more debugging messages for the thread to help pointing where is the problem.
