Summary: CoordinatorShutdownTestrelies on race 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.
