TisonKun created FLINK-10914:
--------------------------------
Summary: Prefer notifying status changed to waiting and checking
in ExecutionGraph tests
Key: FLINK-10914
URL: https://issues.apache.org/jira/browse/FLINK-10914
Project: Flink
Issue Type: Improvement
Components: Tests
Affects Versions: 1.8.0
Reporter: TisonKun
Assignee: TisonKun
Fix For: 1.8.0
Currently there are several tests of {{ExecutionGraph}} based on
{{ExecutionGraphTestUtils#waitUntilJobStatus}} and
{{ExecutionGraphTestUtils#waitUntilExecution(Vertex)State}}. I notice that we
have {{JobStatusListener}}s and {{ExecutionStatusListener}}s registered on a
{{ExecutionGraph}}. It is possible to replace the waiting version with a
notifying version, which is with less cpu workload and more reliable(the
waiting version might miss some very quick status/state changes).
What do you think [~till.rohrmann] [~Zentol]?
