Date Mon, 30 Nov 2015 22:03:11 GMT


Chris updated MESOS-4027:
    Summary: Improve task-node affinity  (was: Improve task-node affinit)

> Improve task-node affinity
> --------------------------
>                 Key: MESOS-4027
>                 URL:
>             Project: Mesos
>          Issue Type: Wish
>          Components: allocation, general
>            Reporter: Chris
>            Priority: Trivial
> Improve task-to-node affinity and anti-affinity (running hadoop or spark jobs on a node
currently running hdfs or to avoid running Ceph on HDFS nodes).
> Provide a user-mutable Attribute in TaskInfo (the Attribute is modified by a Framework
Scheduler) that can describe what a Task is running.
> The Attribute would propagate to a Task at execution. The Attribute is  passed to Framework
Schedulers as part of an Offer's Attributes list. 
> A Framework Scheduler could then filter out or accept Offers from Nodes that are currently
labeled with a desired set or individual Attribute.
