[jira] [Created] (FLINK-21380) Restarting/Canceling/Failing expose globally-terminal EG

Chesnay Schepler created FLINK-21380:
----------------------------------------

             Summary: Restarting/Canceling/Failing expose globally-terminal EG
                 Key: FLINK-21380
                 URL: https://issues.apache.org/jira/browse/FLINK-21380
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.13.0


When the declarative scheduler is in the Restarting state it can expose a fully Canceled EG, because it only overrides {{getJobStatus}}, but the archived execution graph still contains the Canceled job state.
This breaks the contract that the EG only transitions into a terminal state once, and never transitions into another state afterwards.

Related to that the Canceling/Failing states can also expose such an EG because {{State#onGloballyTerminalState}} is called asynchronously. A globally-terminal EG should only be visible in the Finished state however.
