Summary: Workflow for gang scheduling frameworks
Key: MESOS-1334
URL: https://issues.apache.org/jira/browse/MESOS-1334
Project: Mesos
Issue Type: Bug
Reporter: Niklas Quarfot Nielsen
Today, schedulers need to know up-front what to run on an offer. This doesn't
fit well with gang scheduling where multiple resources are reserved and the
launch mechanism not known up front.
With a couple of primitives already in the pipeline, this should be possible by:
- Being able to run an empty job which is marked as TASK_IDLE. Together with
preemptable resources, the idle resource can be used in the interim.
- When all resources have been acquired, use replace task to launch gang
scheduled job.
I'd love to hear some input on gang scheduling, if this would be sufficient and
if you have other ideas on how to address this issue.
