[jira] [Created] (FLINK-13407) Fix thread visibility of checked SlotManager.failUnfulfillableRequest in StandaloneResourceManagerTest

Andrey Zagrebin created FLINK-13407:
---------------------------------------

             Summary: Fix thread visibility of checked SlotManager.failUnfulfillableRequest in StandaloneResourceManagerTest
                 Key: FLINK-13407
                 URL: https://issues.apache.org/jira/browse/FLINK-13407
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.9.0
            Reporter: Andrey Zagrebin
             Fix For: 1.9.0, 1.10.0


One of the potential reasons of the test instability, described in FLINK-13242, is that the test checks _failUnfulfillableRequest_ directly in its thread but it is set in the main RPC thread of _StandaloneResourceManager#initialize_. It can lead to a potential problem with the visibility of _SlotManager.failUnfulfillableRequest_ in _StandaloneResourceManagerTest#testStartupPeriod_.

The idea for the fix is to read _SlotManager.failUnfulfillableRequest_ in the main thread of _StandaloneResourceManager_, get future result and check in the _StandaloneResourceManagerTest.assertHappensUntil_.
