Till Rohrmann commented on FLINK-10914:
---------------------------------------
I guess waiting wouldn't hurt since it is not a super urgent problem.
> 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
> Priority: Major
> 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]?
