------------------------------------
Marking as Unassigned as I need to shift my focus to some other jiras.

> 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).
