Grant Henke commented on KAFKA-2580: ------------------------------------ Marking as Unassigned as I need to shift my focus to some other jiras. > Kafka Broker keeps file handles open for all log files (even if its not > written to/read from) > --------------------------------------------------------------------------------------------- > > Key: KAFKA-2580 > URL: https://issues.apache.org/jira/browse/KAFKA-2580 > Project: Kafka > Issue Type: Bug > Components: core > Affects Versions: 0.8.2.1 > Reporter: Vinoth Chandar > > We noticed this in one of our clusters where we stage logs for a longer > amount of time. It appears that the Kafka broker keeps file handles open even > for non active (not written to or read from) files. (in fact, there are some > threads going back to 2013 > http://grokbase.com/t/kafka/users/132p65qwcn/keeping-logs-forever) > Needless to say, this is a problem and forces us to either artificially bump > up ulimit (its already at 100K) or expand the cluster (even if we have > sufficient IO and everything). > Filing this ticket, since I could find anything similar. Very interested to > know if there are plans to address this (given how Samza's changelog topic is > meant to be a persistent large state use case). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
