Joel Koshy created KAFKA-1755: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
