Klaus Ma commented on MESOS-3366:
---------------------------------
Not sure whether we'll support hot update hardwares, for example, increasing
memory/disk without shutting down the slave. If so, modules/decorators or
child-process are necessary to report hardwares info periodically; and master
adjust resources accordingly.
> Allow resources/attributes discovery

> URL: https://issues.apache.org/jira/browse/MESOS-3366
> Project: Mesos
> Issue Type: Improvement
> Components: slave
> Reporter: Felix Abecassis
>
> In heterogeneous clusters, tasks sometimes have strong constraints on the
> type of hardware they need to execute on. The current solution is to use
> custom resources and attributes on the agents. Detecting non-standard
> resources/attributes requires wrapping the "mesos-slave" binary behind a
> script and use custom code to probe the agent. Unfortunately, this approach
> doesn't allow composition. The solution would be to provide a hook/module
> mechanism to allow users to use custom code performing resources/attributes
> discovery.
