Subject [jira] [Created] (MESOS-7895) ZK session timeout is unconfigurable in agent and scheduler drivers
Date Wed, 16 Aug 2017 13:50:01 GMT
Ilya Pronin created MESOS-7895:
----------------------------------

             Summary: ZK session timeout is unconfigurable in agent and scheduler drivers
                 Key: MESOS-7895
                 URL: https://issues.apache.org/jira/browse/MESOS-7895
             Project: Mesos
          Issue Type: Improvement
    Affects Versions: 1.3.0
            Reporter: Ilya Pronin
            Assignee: Ilya Pronin
            Priority: Minor


{{ZooKeeperMasterDetector}} in agents and scheduler drivers uses the default ZK session timeout
(10 secs). This timeout may have to be increased to cope with long ZK upgrades or ZK GC pauses
(with local ZK sessions these can cause lots of {{TASK_LOST}}, because sessions expire on
disconnection after {{session_timeout * 2 / 3}}).
