---------------------------------------
Summary: E2E test timeout keeps CI running until the timeout ends,
even after the test passes
Key: FLINK-40451
URL: https://issues.apache.org/jira/browse/FLINK-40451
Project: Flink
Issue Type: Technical Debt
Components: Build System / CI
Reporter: Sergey Nuyanzin
Assignee: Sergey Nuyanzin
When an end-to-end test starts, it also starts a hidden sleep timer (e.g. 900s)
as a safety timeout. When the test passes early, we stop the timer's watchdog —
but the sleep itself keeps running. That leftover sleep holds the CI output
pipe open, so the CI step can't finish until the full timeout ends.
