Christopher Hunt commented on MESOS-6136:
-----------------------------------------
Thanks for the reply. However I'm not asking for either of those things.
In the case of MESOS-4659, the suggestion there is that Mesos kills tasks given
the instruction of a framework. What I'm stating is that Mesos shouldn't be
responsible for killing tasks unless an operator (human) intervenes. Killing
tasks is a serious business and can possibly impact a business dramatically.
In the case of the fail over timeout, we're already setting our timeout to 1
week as suggested in order to mitigate this situation. What I'm stating though
is that we shouldn't have to do this.
My point again: only frameworks should instruct Mesos to kill tasks unless
overridden by an operator. The frameworks and operators know best, not Mesos.

> Key: MESOS-6136
> URL: https://issues.apache.org/jira/browse/MESOS-6136
> Project: Mesos
> Issue Type: Improvement
> Components: general
> Affects Versions: 0.28.1
> Environment: DCOS 1.7 Cloud Formation scripts
> Reporter: Christopher Hunt
> Priority: Critical
> Labels: framework, lifecyclemanagement, task
>
> We have observed a situation where Mesos will kill tasks belonging to a
> framework where that framework times out with the Mesos master for some
> reason, perhaps even because of a network partition.
> While we can provide a long timeout so that Mesos will not kill a framework's
> tasks for practical purposes, I'm wondering if there's an improvement where a
> framework shouldn't be permitted to re-register for a given id (as now), but
> Mesos doesn't also kill tasks? What I'm thinking is that Mesos could be
> "told" by an operator that this condition should be cleared.
> IMHO frameworks should be the only entity requesting that tasks be killed
> unless manually overridden by an operator.
> I'm flagging this as a critical improvement because a) the focus should be on
> keeping tasks running in a system, and it isn't; and b) Mesos is working as
> designed.
> In summary I feel that Mesos is taking on a responsibility in killing tasks
> where it shouldn't be.
