Jiangjie Qin commented on KAFKA-6264: ------------------------------------- [~hachikuji] Yes, that may be a workaround. If the first message was the problem. One corner case is that if the segment is the first segment, i.e. 000000000000000.log, in addition to change the segment name to use the first offset of the message, we need to add an empty log segment at 000000000000000.log, otherwise the log starting offset will change. > Log cleaner thread may die on legacy segment containing messages whose > offsets are too large > -------------------------------------------------------------------------------------------- > > Key: KAFKA-6264 > URL: https://issues.apache.org/jira/browse/KAFKA-6264 > Project: Kafka > Issue Type: Bug > Components: core > Affects Versions: 0.10.2.1, 1.0.0, 0.11.0.2 > Reporter: Jiangjie Qin > Assignee: Jiangjie Qin > Priority: Critical > Fix For: 1.0.1 > > > We encountered a problem that some of the legacy log segments contains > messages whose offsets are larger than {{SegmentBaseOffset + Int.MaxValue}}. > Prior to 0.10.2.0, we do not assert the offset of the messages when appending > them to the log segments. Due to KAFKA-5413, the log cleaner may append > messages whose offset is greater than {{base_offset + Int.MaxValue}} into the > segment during the log compaction. > After the brokers are upgraded, those log segments cannot be compacted > anymore because the compaction will fail immediately due to the offset range > assertion we added to the LogSegment. > We have seen this issue in the __consumer_offsets topic so it could be a > general problem. There is no easy solution for the users to recover from this > case. > One solution is to split such log segments in the log cleaner once it sees a > message with problematic offset and append those messages to a separate log > segment with a larger base_offset. > Due to the impact of the issue. We may want to consider backporting the fix > to previous affected versions. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
