Hi everyone, as a follow-up to the earlier discussions, I'm happy to announce that we just landed a patch series that adds the `--reconfiguration_policy=[equal|additive]` flag to the Mesos agent, which allows an agent to change parts of its configured state while still reconnecting to live, running executors and keeping its old agent id.
# What changes are allowed? For now, we opted to keep the set of allowed configuration changes somewhat restricted, mainly because we felt that in particular changing the hostname has some nasty corner-cases that we didn't have the time yet to fully think about. This means that right now, you can only - add additional attributes, - increase static resources, or - add a fault domain. However, if you are compiling Mesos yourself and think you could benefit from relaxing these requirements, I would encourage you to apply https://reviews.apache.org/r/64384/ and share the feedback about any issues it causes (or doesn't cause). Best regards, -- Benno Evers Software Engineer, Mesosphere
