> CoordinatorShutdownTest relies on race condition for success
> ------------------------------------------------------------
>
> Key: FLINK-4972
> URL: https://issues.apache.org/jira/browse/FLINK-4972
> Project: Flink
> Issue Type: Improvement
> Components: Tests
> Affects Versions: 1.2.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Fix For: 1.2.0
>
>
> The CoordinatorShutdownTest verifies that the CheckpointCoordinator is
> properly shutdown when a job has succeeded/failed. For this purpose a job is
> submitted to a cluster without TaskManagers, resulting in immediate failure.
> The ExecutionGraph is then retrieved, from which the CheckpointCoordinator
> can be accessed.
> This test relies on being able to access the ExecutionGraph for a finished
> job even though it is only accessible for a short amount of time: until it
> was archived and removed from the currentJobs map in the JM. From that point
> on you can only retrieve an ArchivedExecutionGraph, which doesn't contain the
> CheckpointCoordinator anymore.
> The tests should be changed to block the job execution, retrieve the
> ExecutionGraph, resume the job and then verify the test conditions.
