Qian Zhang commented on MESOS-4027:
-----------------------------------
[~ct.clmsn], I think there is already a "labels" field in TaskInfo, is that
enough for your use case?
And what did you mean about "The Attribute is passed to Framework Schedulers as
part of an Offer's Attributes list."? I think offer's attribute list will only
consist of the attribute of Mesos agent (slave), it should not include anything
about task.
> Improve task-node affinity

> URL: https://issues.apache.org/jira/browse/MESOS-4027
> 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.
