             Summary: Add a master flag to disallow agents that are not configured with fault domain
                 Key: MESOS-8115
                 URL: https://issues.apache.org/jira/browse/MESOS-8115
             Project: Mesos
          Issue Type: Bug
            Reporter: Vinod Kone
            Assignee: Vinod Kone


Once mesos masters and agents in a cluster are *all* upgraded to a version where the fault domains feature is available, it is beneficial to enforce that agents without a fault domain configured are not allowed to join the cluster. 

This is a safety net for operators who could forget to configure the fault domain of a remote agent and let it join the cluster. If this happens, an agent in a remote region will be considered a local agent by the master and frameworks (because agent's fault domain is not configured) causing tasks to potentially land in a remote agent which is undesirable.

Note that this has to be a configurable flag and not enforced by default because otherwise upgrades from a fault domain non-configured cluster to a configured cluster will not be possible.
