Joseph Wu commented on MESOS-3220:
----------------------------------

Keep in mind there's a distinction between maintenance and inverse offers.  
Maintenance uses inverse offers, but due to maintenance's operator-heavy 
nature, all killing is must be done by the operator.

If inverse offers were used for trimming specific tasks, perhaps as part of a 
custom allocator, it would make sense for the custom allocator to implement 
automated killing.  But it would not make sense for the default allocator to 
auto-kill.

> We are investigating adding a {{dcos task kill}} command to our DCOS (and 
> Mesos) command line interface. Currently the ability to kill tasks is only 
> offered via the scheduler API so it would be useful to have some ability to 
> kill tasks directly.
> This would complement the Maintenance Primitives, in that it would enable the 
> operator to terminate those tasks which, for whatever reasons, do not respond 
> to Inverse Offers events.
