Meng Zhu created MESOS-9359:
-------------------------------
Summary: Test `DefaultExecutorTest.MaxCompletionTime` is flaky.
Key: MESOS-9359
URL: https://issues.apache.org/jira/browse/MESOS-9359
Project: Mesos
Issue Type: Bug
Reporter: Meng Zhu
Attachments: DefaultExecutorTest.MaxCompletionTime
The test is flaky because its task with simple command `exit 0` took more than
2 seconds to complete (even though the container successfully transitioned to
running state) which is not expected by the test, log snippets:
