-----------------------------------

             Summary: Setting logbufsecs to 0 causes Impala to spin on one core
                 Key: IMPALA-5763
                 URL: https://issues.apache.org/jira/browse/IMPALA-5763
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.9.0
            Reporter: Lars Volker
            Priority: Critical


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.
