> 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
> Assignee: Abhishek Dasgupta
> Labels: mesosphere
>
> 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.
