Jun Rao created KAFKA-6780:
------------------------------
Summary: 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
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.
