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

             Summary: Create ContainerID; Rename ResourceID into ProcessID and InstanceID into RegistrationID
                 Key: FLINK-4755
                 URL: https://issues.apache.org/jira/browse/FLINK-4755
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.2.0
            Reporter: Till Rohrmann
            Priority: Minor


Currently, the {{ResourceID}} is used to identify a container as well as the process running in the container. With Flip-6, we should introduce a dedicated {{ContainerID}} and rename {{ResourceID}} into {{ProcessID}}. The {{ProcessID}} would then be constructed from the {{ContainerID}} and some {{UUID}}, for example.

Additionally we could rename {{InstanceID}} into {{RegistrationID}} which would better reflect its true purpose.
