--------------------------------------
Summary: 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
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.
