Target Version/s: 1.6.0 (was: 1.5.0)
> Support for agent lifecycle management.
> ---
>
> Key: MESOS-7426
> URL: https://issues.apache.org/jira/browse/MESOS-7426
> Project: Mesos
> Issue Type: Epic
> Components: agent
>Reporter: Anand Mazumdar
>Assignee: Anand Mazumdar
> Labels: agent-lifecycle, mesosphere
>
> This epic co-ordinates the work for introducing agent lifecycle management in
> Mesos allowing a framework to be notified in case of agent node failures. The
> existing {{Event::Failure}} is not enough for frameworks to know that the
> given agent node isn't ever coming back.
> The primary motivations for introducing such a feature would be:
> - Currently, when an agent running a task fails, there is inherently an
> operator interference needed (manual step) to remove the node via a
> configuration API exposed by the framework e.g., dcos cassandra node replace
> for the cassandra framework. This needs to be done once for every stateful
> framework running on the cluster.
> - When an agent is marked as unhealthy, the removal rate is bounded if the
> `--agent_rate_removal_limit` option is set. This is specifically problematic
> for operators relying on EC2 autoscaling groups or for workload bursting to
> another cloud.
> - When an agent is marked as unhealthy, the removal rate is bounded if the
> `--agent_rate_removal_limit` option is set. This is specifically problematic
> for operators relying on EC2 autoscaling groups or for workload bursting to
> another cloud.
> - When the fault domain associated with an agent changes (e.g., it is moved
> from an unallocated rack to an allocated rack), there is no feedback
> mechanism for the framework.
