-----------------------------------------

             Summary: Multiple ResourceManagers register at JobManager in standalone HA mode
                 Key: FLINK-3982
                 URL: https://issues.apache.org/jira/browse/FLINK-3982
             Project: Flink
          Issue Type: Bug
          Components: ResourceManager
    Affects Versions: 1.1.0
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels
            Priority: Minor
             Fix For: 1.1.0


In HA mode, multiple ResourceManagers may register at the leading JobManager. They register
one after another at the JobManager. The last registering ResourceManager stays registered
with the JobManager. This only applies to Standalone mode and doesn't affect functionality.

To prevent duplicate registration for the standalone ResourceManager, the easiest solution
is to only start registration when the leading JobManager runs in the same ActorSystem as
the ResourceManager. Other ResourceManager implementations may also run independently of the
JobManager.
