Resolution: Duplicate
> Support dynamic allocation for coarse-grained Mesos
> ---------------------------------------------------
>
> Key: SPARK-4922
> URL: https://issues.apache.org/jira/browse/SPARK-4922
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 1.2.0
> Reporter: Andrew Or
> Priority: Critical
>
> This brings SPARK-3174, which provided dynamic allocation of cluster
> resources to Spark on YARN applications, to Mesos coarse-grained mode.
> Note that the translation is not as trivial as adding a code path that
> exposes the request and kill mechanisms as we did for YARN is SPARK-3822.
> This is because Mesos coarse-grained mode schedules on the notion of setting
> the number of cores allowed for an application (as in standalone mode)
> instead of number of executors (as in YARN mode). For more detail, please see
> SPARK-4751.
> If you intend to work on this, please provide a detailed design doc!
