Chris created MESOS-4027: ---------------------------- Summary: Improve task-node affinit Key: MESOS-4027 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
