>
> An external application (an Ops script, or some CLI-based tool) can change
> the configuration of the Capacity Scheduler (change the capacities of various
> queues, for example) by updating its config file. This application then needs
> to tell the Capacity Scheduler that its config has changed, which causes the
> Scheduler to re-read its configuration. It's possible that the Capacity
> Scheduler may need to interact with external applications in other similar
> ways.
