---------------------------------
Summary: Log cleaner thread should not exit on errors
Key: KAFKA-1755
URL: https://issues.apache.org/jira/browse/KAFKA-1755
Project: Kafka
Issue Type: Bug
Reporter: Joel Koshy
Fix For: 0.8.3
The log cleaner is a critical process when using compacted topics.
However, if there is any error in any topic (notably if a key is missing) then
the cleaner exits and all other compacted topics will also be adversely
affected - i.e., compaction stops across the board.
This can be improved by just aborting compaction for a topic on any error and
keep the thread from exiting.
Another improvement would be to reject messages without keys that are sent to
compacted topics although this is not enough by itself.
