Neil Conway commented on MESOS-7317:
------------------------------------
Yes, this is for maintenance-unaware frameworks.
"Operator manually drain" is killing task processes by hand, e.g., via
{{pkill}} or a framework-level (e.g., Marathon/Aurora/etc.) {{killTask}}.
> Add master endpoint to deactivate / activate agent

> Issue Type: Improvement
> Components: agent, master
> Reporter: Neil Conway
> Labels: mesosphere
>
> This would allow the operator to deactivate and then subsequently activate an
> agent. The allocator does not make offers for deactivated agents; this
> functionality would be useful to help operators "manually (incrementally)
> drain" the tasks running on an agent, e.g., before taking the agent down.
> At present, if the operator causes a framework to kill a task running on the
> agent, the framework will often receive an offer for the unused resources on
> the agent, which will often result in respawning the killed task on the same
> agent.
