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