> Scheduler for Mesos in fine-grained mode launches tasks on wrong executors
> --------------------------------------------------------------------------

> Key: SPARK-2204
> URL: https://issues.apache.org/jira/browse/SPARK-2204
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 1.0.0
> Reporter: Sebastien Rainville
> Priority: Blocker
> Fix For: 1.0.1, 1.1.0
>
>
> MesosSchedulerBackend.resourceOffers(SchedulerDriver, List[Offer]) is
> assuming that TaskSchedulerImpl.resourceOffers(Seq[WorkerOffer]) is returning
> task lists in the same order as the offers it was passed, but in the current
> implementation TaskSchedulerImpl.resourceOffers shuffles the offers to avoid
> assigning the tasks always to the same executors. The result is that the
> tasks are launched on the wrong executors.
