[jira] [Created] (YUNIKORN-302) flaky reservation tests caused by timing issue

----------------------------------------------

             Summary: flaky reservation tests caused by timing issue
                 Key: YUNIKORN-302
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-302
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: core - scheduler, test - unit
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg


The reservation tests are not stable. They can fail for a number of reasons.
Reservations are normally not triggered unless the request is more than 2 seconds old. In some tests we lower this to 10 milliseconds. Most tests use 1 nanosecond. The tests that use the 10 msec fail intermittantly.

In the case that we have a fast(er) system to test on this delay is too long all scheduling actions will be finished before we get to the 10 msec delay.
