             Summary: Add master endpoint to deactivate / activate agent
                 Key: MESOS-7317
                 URL: https://issues.apache.org/jira/browse/MESOS-7317
             Project: Mesos
          Issue Type: Improvement
          Components: agent, master
            Reporter: Neil Conway


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 receive an offer for the unused resources on the 
agent, which will often result in respawning the killed task on the same agent.
