[jira] [Commented] (MESOS-6177) Return unregistered agents
recovered from registrar in `GetAgents` and/or `/state.json`
[ https://issues.apache.org/jira/browse/MESOS-6177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15572997#comment-15572997 ]
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.

> 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.
