--------------------------------------
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.
