Jim, Currently, we don't have a tool to forcefully delete log files. If you want to clean the log files after a test run, assuming that no producers/consumers are running, you can simply delete the log directory. The next time a kafka server starts up, it will recreate the log directory. If you want to delete some log files while a Kafka server is running, assuming that there are no consumers running, you can delete all but the latest log segment for each partition and then restart the Kafka server. If you have consumers actively consuming data from older log segments, they will run into errors if you delete the log segments that the server was trying to serve messages from.
