----------------------------------------
Summary: DataStreamAllroundTestProgram should define pause between
checkpoints
Key: FLINK-12467
URL: https://issues.apache.org/jira/browse/FLINK-12467
Project: Flink
Issue Type: Bug
Components: Test Infrastructure
Affects Versions: 1.9.0
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Since the {{DataStreamAllroundTestProgram}} does not define a minimum pause
between checkpoints it can happen that the {{CheckpointCoordinator}} attempts
to start a checkpoint while another one is still on-going.
This results in a failed checkpoint if this checkpoint exceeds the maximum
number of concurrent checkpoints, which in our e2e tests results in a test
failure since the logs contain exceptions.
