Subject [jira] [Created] (MESOS-5368) Consider introducing persistent agent ID

----------------------------------

             Summary: Consider introducing persistent agent ID
                 Key: MESOS-5368
                 URL: https://issues.apache.org/jira/browse/MESOS-5368
             Project: Mesos
          Issue Type: Improvement
            Reporter: Neil Conway


Currently, agent IDs identify a single "session" by an agent: that is, an agent receives an
agent ID when it registers with the master; it reuses that agent ID if it disconnects and
successfully reregisters; if the agent shuts down and restarts, it registers anew and receives
a new agent ID.

It would be convenient to have a "persistent agent ID" that remains the same for the duration
of a given agent {{work_dir}}. This would mean that a given persistent volume would not migrate
between different agent IDs over time, for example (see MESOS-4894). If we supported permanently
removing an agent from the cluster (i.e., the {{work_dir}} and any volumes used by the agent
will never be reused), we could use the persistent agent ID to report which agent has been
removed.
