I am looking at POCing Mesos in our environment to run not only data analytics but scheduling long lived services across clusters with something like Aurora. So my question is : Is it possible to dynamically add to the pool across which Mesos schedules at runtime?
E.g. We have Openstack clusters and I would like to dynamically make a pool of VMs available to schedule across if needed (in addition to bare metal machines) Also, are there any efforts underway to run HBase via Mesos? I see it mentioned in a few places, but it is not listed as a Mesos Framework.
