> Key: IMPALA-5763
> URL: https://issues.apache.org/jira/browse/IMPALA-5763
> Project: IMPALA
> Issue Type: Documentation
> Components: Docs
> Affects Versions: Impala 2.9.0
> Reporter: Lars Volker
> Assignee: Alex Rodoni
> Priority: Minor
> Fix For: Impala 2.13.0, Impala 3.1.0
>
>
> Starting impalad with -logbufsecs 0 makes it spin in the thread that tries to
> delete old logfiles.
> [~tarmstrong], [~henryr] - Is this intended? If not, one fix would be to
> sleep for {{std::max(1, FLAGS_logbufsecs)}} in {{LogMaintenanceThread()}}.
> Another option would be to require a value >0 for logbufsecs.
