Rajini Sivaram created KAFKA-12996: -------------------------------------- Summary: OffsetOutOfRange not handled correctly for diverging epochs when fetch offset less than leader start offset Key: KAFKA-12996 URL: https://issues.apache.org/jira/browse/KAFKA-12996 Project: Kafka Issue Type: Bug Components: core Affects Versions: 2.8.0 Reporter: Rajini Sivaram Assignee: Rajini Sivaram Fix For: 3.0.0, 2.8.1
{color:#24292e}If fetchOffset < startOffset, we currently throw OffsetOutOfRangeException when attempting to read from the log in the regular case. But for diverging epochs, we return Errors.NONE with the new leader start offset, hwm etc.. ReplicaFetcherThread throws OffsetOutOfRangeException when processing responses with Errors.NONE if the leader's offsets in the response are out of range and this moves the partition to failed state. We should add a check for this case when processing fetch requests and ensure OffsetOutOfRangeException is thrown regardless of epochs.{color} -- This message was sent by Atlassian Jira (v8.3.4#803005)
