[jira] [Created] (MESOS-155) Add preemption scheduling via a new
allocation module
Add preemption scheduling via a new allocation module
-----------------------------------------------------
Key: MESOS-155
URL: https://issues.apache.org/jira/browse/MESOS-155
Project: Mesos
Issue Type: Task
Components: master
Reporter: Andy Konwinski
Priority: Minor
Mesos currently has an allocation module that provides Dominant Resource Fairness (essentially, fair sharing across multiple resources), but it does not currently support preemption so the allocation module cannot currently enforce the scheduling rules by bringing a scheduler down to its fair share of resources when necessary.
For example, if Framework A registers with the master when no other frameworks are registered, it will be offered all resources. Then if Framework B registers as well, it won't be offered any resources until at least one of Framework A's tasks finish running. Ideally the Allocation Module should be able to preempt (kill) some of Framework A's tasks to guarantee Framework B receives offers so that it could get up to its fair share.
