---------------------------------------
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_.
