             Summary: flink-mesos: Support for adding unique attribute / group_by attribute constraints
                 Key: FLINK-7486
                 URL: https://issues.apache.org/jira/browse/FLINK-7486
             Project: Flink
          Issue Type: Improvement
          Components: Mesos
    Affects Versions: 1.3.2
            Reporter: Bhumika Bayani


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.
