Jun Rao commented on KAFKA-6780: -------------------------------- The fix is probably to further bound firstUncleanableDirtyOffset by the high watermark. > log cleaner shouldn't clean messages beyond high watermark > ---------------------------------------------------------- > > Key: KAFKA-6780 > URL: https://issues.apache.org/jira/browse/KAFKA-6780 > Project: Kafka > Issue Type: Bug > Affects Versions: 1.1.0 > Reporter: Jun Rao > Priority: Major > > Currently, the firstUncleanableDirtyOffset computed by the log cleaner is > bounded by the first offset in the active segment. It's possible for the high > watermark to be smaller than that. This may cause a committed record to be > removed because of an uncommitted record. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
