-------------------------------------
Summary: provide a mechanism to run a task on every slave
Key: AURORA-389
URL: https://issues.apache.org/jira/browse/AURORA-389
Project: Aurora
Issue Type: Task
Components: Client, Scheduler
Reporter: David Robinson
Priority: Minor
Aurora does not provide a mechanism for running a task on every slave. The
config for a job requires that the number of instances be specified in advance,
but it's not practical to adjust this number whenever slaves are added or
removed. If this mechanism were available it could be used to run Thermos
Observer or other tasks which need to be run on every slave. Without this
mechanism everyone will need to duplicate Aurora's deployment mechanism outside
of Aurora. If we could use Aurora to deploy these components we'd avoid this
duplication.
