Moritz Siuts commented on KAFKA-3802: ------------------------------------- This https://github.com/emetriq/kafka/commit/94bca24bcef5d479f1e4350c65faad2bf7a09246 seems to fix the issue. Before I do a PR I need to add a good unit tests for the change, but maybe you already have feedback. > log mtimes reset on broker restart > ---------------------------------- > > Key: KAFKA-3802 > URL: https://issues.apache.org/jira/browse/KAFKA-3802 > Project: Kafka > Issue Type: Bug > Affects Versions: 0.9.0.1 > Reporter: Andrew Otto > > Folks over in > http://mail-archives.apache.org/mod_mbox/kafka-users/201605.mbox/%3CCAO8=cz0ragjad1acx4geqcwj+rkd1gmdavkjwytwthkszfg...@mail.gmail.com%3E > are commenting about this issue. > In 0.9, any data log file that was on > disk before the broker has it's mtime modified to the time of the broker > restart. > This causes problems with log retention, as all the files then look like > they contain recent data to kafka. We use the default log retention of 7 > days, but if all the files are touched at the same time, this can cause us > to retain up to 2 weeks of log data, which can fill up our disks. > This happens *most* of the time, but seemingly not all. We have seen broker > restarts where mtimes were not changed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
