             Summary: Master asks agent to shutdown upon auth errors
                 Key: MESOS-8987
                 URL: https://issues.apache.org/jira/browse/MESOS-8987
             Project: Mesos
          Issue Type: Bug
          Components: master, security
    Affects Versions: 1.6.0, 1.5.1, 1.4.1, 1.7.0
            Reporter: Gastón Kleiman


The Mesos master sends a {{ShutdownMessage}} to an agent if there is an [authentication|https://github.com/apache/mesos/blob/d733b1031350e03bce443aa287044eb4eee1053a/src/master/master.cpp#L6532-L6543] or an [authorization|https://github.com/apache/mesos/blob/d733b1031350e03bce443aa287044eb4eee1053a/src/master/master.cpp#L6622-L6633] error during agent registration.
 
Upon receipt of this message, the agent kills alls its tasks and commits suicide. This means that transient auth errors can lead to whole agents being killed along with it's tasks.

I think the master should stop sending the {{ShutdownMessage}}s in these cases, or at least let the agent retry the registration a few times before asking it to shutdown.
