Description

Hi,

We are going by Mesos Maintenance Primitives documentation here http://mesos.apache.org/documentation/latest/maintenance/. My requirement is "that during a Agent maintenance we want to move all running tasks from this agent to other Agents without task failed/stop". This is how you do zero downtime maintenance without affecting the running tasks. I see that in the documentation "we submit a maintenance schedule" which sends inverse offer to Framework to plan tasks according to the agent(s) unavailability. But Drain mode is not working here. I mean b/w submissions maintenance-schedule and Agent-down, tasks are not moved from the agents going under maintenance to other agents. As a result we cannot achieve a 100% full proof maintenance process.

Can you please elaborate on the "framework respond to inverse offer" process or "Drain mode" step. This is very critical part in the maintenance. Other steps are fine and working for us (de-registering and re-registering agent from&to cluster)

Thanks
