--------------------------------
Summary: Error with unit test for hdds.container-service
TestSchemaOneBackwardsCompatibility
Key: HDDS-5099
URL: https://issues.apache.org/jira/browse/HDDS-5099
Project: Apache Ozone
Issue Type: Bug
Reporter: Neil Joshi
Assignee: Neil Joshi
Attachments: intermittent_err.png, intermittent_fix.png
The unit test _testDelete_ from _TestSchemaOneBackwardsCompatibility_
(_hadoop-hdds/container-service_) has an observed reproducible intermittent
error. This error is due to the test launching a background task
(_BackgroundService.java_) that it expects to block to completion, however it
does not. The test, through a thread pool executor launches a task to delete
blocks and expects to block until completion. After blocked until completion
it checks the worker result. Since the current implementation does not block,
at times the worker is not done before the test checks the condition, hence the
intermittent error.
Observed error:
{code:java}
mvn -Dtest=TestSchemaOneBackwardsCompatibility test{code}
(see attachment err)
With waiting until worker task is finished before checking condition: (see
attachment showing test passed)
