Jason Gustafson created KAFKA-4298: -------------------------------------- Summary: LogCleaner does not convert compressed message sets properly Key: KAFKA-4298 URL: https://issues.apache.org/jira/browse/KAFKA-4298 Project: Kafka Issue Type: Bug Reporter: Jason Gustafson Assignee: Jason Gustafson Priority: Critical Fix For: 0.10.1.1
When cleaning the log, we attempt to write the cleaned messages using the message format configured for the topic, but as far as I can tell, we do not convert the wrapped messages in compressed message sets. For example, if there is an old compressed message set with magic=0 in the log and the topic is configured for magic=1, then after cleaning, the new message set will have a wrapper with magic=1, but the nested messages will still have magic=0. If this happens, there does not seem to be an easy way to recover with manually fixing up the log. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
