[jira] [Created] (KAFKA-10101) recovery point is advanced without flushing the data after recovery

Jun Rao created KAFKA-10101:
-------------------------------

             Summary: recovery point is advanced without flushing the data after recovery
                 Key: KAFKA-10101
                 URL: https://issues.apache.org/jira/browse/KAFKA-10101
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 2.5.0
            Reporter: Jun Rao


Currently, in Log.recoverLog(), we set recoveryPoint to logEndOffset after recovering the log segment. However, we don't flush the log segments after recovery. The potential issue is that if the broker has another hard failure, segments may be corrupted on disk but won't be going through recovery on another restart.

This logic was introduced in KAFKA-5829 since 1.0.0.
