> Add a new hook in makeOffers in CoarseGrainedSchedulerBackend
> -------------------------------------------------------------
>
> Key: SPARK-16455
> URL: https://issues.apache.org/jira/browse/SPARK-16455
> Project: Spark
> Issue Type: New Feature
> Components: Scheduler
> Reporter: YangyangLiu
> Priority: Minor
>
> In our case, we are implementing restartable resource manager mechanism which
> will let master executor survive when resource manager service is temporarily
> down. So when resource manager service is not available, scheduler should
> stop scheduling new tasks. I added a hook inside
> CoarseGrainedSchedulerBackend class, in order to avoid new task scheduling
> when it's necessary.
