Anu Engineer commented on HDDS-1127:
------------------------------------
+1, Please do. Let us also spend some time on these tests, some times they are
flaky by design. So it might be a good idea to rewrite them or modify code to
be more testable.
> Fix failing and intermittent Ozone unit tests
> ---------------------------------------------
>
> Key: HDDS-1127
> URL: https://issues.apache.org/jira/browse/HDDS-1127
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Reporter: Elek, Marton
> Assignee: Elek, Marton
> Priority: Blocker
>
> Full Ozone build with acceptance + unit tests takes ~1.5 hour.
> In the last 30 hours I executed a new full build at every 2 hours and
> collected all the results.
> We have ~1200 test method and ~15 are failed more than 4 times out of the 17
> run.
> I propose the following method to fix them:
> # Turn them off immediately (@Skip) to get real data for the pre-commits
> # Create a Jira for every failing tests *with assignee* (I would choose an
> assignee based on the history of the unit test). We can adjust the assignee
> later but I would prefer use a default person instead of creating unassigned
> jira-s.
> # Fix them and enable the tests again.
> Failing tests are the following:
