---------------------------------
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.
