[jira] [Created] (HDDS-2535) TestOzoneManagerDoubleBufferWithOMResponse is flaky

Marton Elek created HDDS-2535:
---------------------------------

             Summary: TestOzoneManagerDoubleBufferWithOMResponse is flaky
                 Key: HDDS-2535
                 URL: https://issues.apache.org/jira/browse/HDDS-2535
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Manager
            Reporter: Marton Elek


Flakiness can be reproduced locally. Usually it passes, but when I started to run it 100 times parallel with high cpu load it failed with the 3rd attempt (timed out)
{code:java}

 {code}
Independent from the flakiness I think a test where the timeout is 8 minutes and starts 1000 threads to insert 500 buckets (500_000 buckets all together) it's more like an integration test and would be better to move the slowest part to the integration-test project.
