[jira] [Created] (SAMZA-2046) Startpoints - job coordinators need to re-map startpoints from SSP key to SSP+TaskName key

Daniel Nishimura created SAMZA-2046:
---------------------------------------

             Summary: Startpoints - job coordinators need to re-map startpoints from SSP key to SSP+TaskName key
                 Key: SAMZA-2046
                 URL: https://issues.apache.org/jira/browse/SAMZA-2046
             Project: Samza
          Issue Type: New Feature
    Affects Versions: 1.1
            Reporter: Daniel Nishimura
            Assignee: Daniel Nishimura


The job coordinators need to call the StartpointManager#groupStartpointsPerTask method that handles the re-mapping. What needs to be implemented is when this method should be called in the job coordinators.

YARN - ClusterBasedJobCoordinator should call the method before starting the processing containers.

Standalone - The job coordinator should call the method when the leader is elected and before the other processors begin processing.
