> Add support for multiple offers in launchTasks
> ----------------------------------------------

> Key: MESOS-749
> URL: https://issues.apache.org/jira/browse/MESOS-749
> Project: Mesos
> Issue Type: Improvement
> Reporter: Niklas Quarfot Nielsen
> Assignee: Niklas Quarfot Nielsen
> Fix For: 0.17.0
>
>
> Running tasks on more than one offer (which belong to a single slave) can be
> useful in situations with multiple out-standing offers. Currently, only one
> offer can be used per launch.
> Offer resources can be aggregated and used for traditional task launch.
> Feature involves:
> - Extending the scheduler API with launchTasks(offers, tasks, filters) with
> takes a list of offers and opposed to a single offer.
> - Extending LaunchTasksMessage to carry offer list.
> - Extend the offer to offer list in call-path from scheduler to master.
> - Master applies offer visitors to validate and aggregate offers into a
> single resource, before task validation and launch is carried out.
> Java and Python interfaces should support both the new and old launchTasks()
> for backward compatibility.
