I'm seeing a problem where I have some compacted topics on my kafka cluster (3 node). When there is a fresh startup of kafka and zookeeper, and I create compact topics with a service running that writes to this topic, I see log cleaner thread is not running. It has no logs in /var/log/kafka/log-cleaner.log. How can I manually start the log cleaner thread if it doesn't start by itself? What is a good way to monitor log cleaner thread?
