>             Project: Flink
>          Issue Type: Improvement
>          Components: Mesos
>    Affects Versions: 1.3.2

>
> In our setup, we have multiple mesos-workers. Inspite of this, flink application master most of the times ends up spawning all task-managers on same mesos-worker.
> We intend to ensure HA of task managers. We would like to make sure each task-manager is running on different mesos-worker as well as such mesos-worker which does not share the AZ attribute with earlier task manager instances.
> Netflix-fenzo supports adding UniqueHostAttribute and BalancedHostAttribute contraints. Flink-mesos should also enable us to add these kind of constraints.
