Chesnay Schepler created FLINK-6567:
---------------------------------------
Summary: ExecutionGraphMetricsTest fails on Windows CI
Key: FLINK-6567
URL: https://issues.apache.org/jira/browse/FLINK-6567
Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.3.0, 1.4.0
Reporter: Chesnay Schepler
Priority: Minor
The {{testExecutionGraphRestartTimeMetric}} fails every time i run it on
AppVeyor. It also very rarely failed for me locally.
The test fails at Line 235 if the RUNNING timestamp is equal to the RESTARTING
timestamp, which may happen when combining a fast test with a low resolution
clock.
A simple fix would be to increase the timestamp between RUNNING and RESTARTING
by adding a 50ms sleep timeout into the {{TestingRestartStrategy#canRestart()}}
method, as this one is called before transitioning to the RESTARTING state.
