Tobias Weingartner commented on AURORA-285:
-------------------------------------------

Through setting a scheduling constraint, and updating/rolling a (portion of a) job.  Other
options?

> in order to support testing and other host specific uses, it would be nice to be able
to reserve a set of hosts (possibly through a slave attribute) from being considered for scheduling,
unless a set of constraints forces tasks onto these specific hosts.
> The "dedicated" attribute is too much, as it restricts the tasks to be of a certain role.
 In this case, we'd like to allow any task in any role to be able to request to these reserved
resources.
