             Summary: follower can hit OffsetOutOfRangeException during truncation
                 Key: KAFKA-12153
                 URL: https://issues.apache.org/jira/browse/KAFKA-12153
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 2.7.0
            Reporter: Jun Rao
            Assignee: Jason Gustafson


Currently, we have the following code path.

log.truncateTo() => updateLogEndOffset() => updateHighWatermarkMetadata() => maybeIncrementFirstUnstableOffset() => convertToOffsetMetadataOrThrow() => read()

This path seems problematic. The issue is that updateLogEndOffset() is called before loadProducerState() in log.truncateTo(). At that point, the producerState is not reflecting the truncated state yet and producerStateManager.firstUnstableOffset(called in maybeIncrementFirstUnstableOffset() to feed read()) could return an offset larger than the truncated logEndOffset, which will lead to OffsetOutOfRangeException.

 

This issue is relatively rare since it requires truncation below the high watermark.
