---------------------------------
Assignee: Benno Evers (was: Vinod Kone)
> 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: Improvement
> Reporter: Vinod Kone
> Assignee: Benno Evers
>
> 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.
