--------------------------------------
Summary: support a cluster service job priority
Key: AURORA-1111
URL: https://issues.apache.org/jira/browse/AURORA-1111
Project: Aurora
Issue Type: Story
Components: Scheduler
Reporter: Jay Buffington
I propose we support a "cluster service" (I'm open to alternative names)
priority level which is higher than production. Jobs in this priority would be
able to preempt production jobs and would not be subject to quota. Only a very
small set of cluster administrators would be able to start jobs at this
priority level.
Thermos observer in it's current incarnation is the best example of something
that would run at this priority. We currently accomplish guaranteeing that the
observer is running by starting it out of band of mesos. With this change we
would be able to start an observer on a slave through aurora, even if that
particular slave is "full" of production tasks.
There are other examples of cluster services, such as a splunk forwarder, or
the mesos-slave process (eek! turtles!)
