Paolo Patierno commented on KAFKA-3925: --------------------------------------- In my opinion, putting the log in /tmp is great for all developers who start to use Kafka or for testing as well. They don't need to remember to delete such logs after "playing" around with Kafka. I think that as default is good. If people need persistence of such logs, they should change the logs dir. I think that just warning on startup could be enough. > Default log.dir=/tmp/kafka-logs is unsafe > ----------------------------------------- > > Key: KAFKA-3925 > URL: https://issues.apache.org/jira/browse/KAFKA-3925 > Project: Kafka > Issue Type: Bug > Components: config > Affects Versions: 0.10.0.0 > Environment: Various, depends on OS and configuration > Reporter: Peter Davis > > Many operating systems are configured to delete files under /tmp. For > example Ubuntu has > [tmpreaper|http://manpages.ubuntu.com/manpages/wily/man8/tmpreaper.8.html], > others use tmpfs, others delete /tmp on startup. > Defaults are OK to make getting started easier but should not be unsafe > (risking data loss). > Something under /var would be a better default log.dir under *nix. Or > relative to the Kafka bin directory to avoid needing root. > If the default cannot be changed, I would suggest a special warning print to > the console on broker startup if log.dir is under /tmp. > See [users list > thread|http://mail-archives.apache.org/mod_mbox/kafka-users/201607.mbox/%3cCAD5tkZb-0MMuWJqHNUJ3i1+xuNPZ4tnQt-RPm65grxE0=0o...@mail.gmail.com%3e]. > I've also been bitten by this. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
