>                 Key: SPARK-10444
>                 URL: https://issues.apache.org/jira/browse/SPARK-10444
>             Project: Spark
>          Issue Type: Bug
>          Components: Mesos
>    Affects Versions: 1.5.0
>            Reporter: Iulian Dragos
>            Priority: Major
>              Labels: bulk-closed, refactoring

> Currently coarse-grained and fine-grained Mesos schedulers don't share much code, and that leads to inconsistencies. For instance:
> - only coarse-grained mode respects {{spark.cores.max}}, see SPARK-9873
> - only coarse-grained mode blacklists slaves that fail repeatedly, but that seams like generally useful
> - constraints and memory checking are done on both sides (code is shared though)
> - framework re-registration (master election) is only done for cluster-mode deployment
> We should find a better design that groups together common concerns and generally improves the code.
