Flink Jira Bot updated FLINK-19928:
-----------------------------------
Priority: Minor (was: Major)
> Introduce test configuration to detect instabilities better
> -----------------------------------------------------------
>
> Key: FLINK-19928
> URL: https://issues.apache.org/jira/browse/FLINK-19928
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination, Tests
> Reporter: Robert Metzger
> Priority: Minor
> Labels: auto-deprioritized-major
>
> As part of debugging FLINK-19805, I noticed that invalid system states
> sometimes depend on configuration values.
> For example the "heartbeat.interval" is configured to 10 seconds by default.
> Many tests are not running that long, making it difficult to find test
> failures related to the heartbeat.
> Similarly, to intervals, also retry configurations can cause failures to be
> hidden.
> It will be difficult to spread this to all tests, but adding it to the
> {{MiniClusterResource}} would be a start.
