Zhitao Li commented on MESOS-6177:
----------------------------------
[~anandmazumdar], I'm strongly inclined to return the full {{AgentInfo}}
instead of only {{AgentID}} for agents in {{recovered}} state.
My primary intention is to have a hold of {{pid}}, so the operator/subscriber
can know the ip:port the agent is listening at. If we only return {{AgentID}},
the operator can do little additional babysitting steps to validate the state
of the agent, except for waiting for {{--agent_reregistration_timeout}} to pass.
This is also pretty easy to implement IIUIC: we can simply change the
{{slaves.recovered}} from {{hashset<SlaveID>}} to {{hashmap<SlaveID,
SlaveInfo>}}. The {{SlaveInfo}} is already available after Registrar recovers
it.
> Return unregistered agents recovered from registrar in `GetAgents` and/or
> `/state.json`

> Use case:
> This can be used for any software which talks to Mesos master to better
> understand state of an unregistered agent after a master failover.
> If this information is available, the use case in MESOS-6174 can be handled
> with a simpler decision of whether the corresponding agent is removed.
