MartijnVisser opened a new pull request, #28757:
URL: https://github.com/apache/flink/pull/28757
## What is the purpose of the change
Backport to `release-2.3` of four test-stabilization fixes for
`RescaleTimelineITCase`, cherry-picked in master-chronological order:
- `[FLINK-40009]` Enforce timeout in the `RescaleTimelineITCase` wait helper
(master commit `1268adfdb03`)
- `[FLINK-40010]` Fix race in
`testRescaleTerminatedByNoResourcesOrNoParallelismsChange` (master commit
`ad2dee480a6`)
- `[FLINK-40076]` Fix race in
`testRecordNonTerminatedRescaleMergingWithNewRecoverableFailureTriggerCause`
(master commit `7f770b87178`)
- `[FLINK-40067]` Fix race in `testRescaleTerminatedByJobFinished` (master
commit `edba4901475`)
`RescaleTimelineITCase` exists only on `release-2.3` (not 2.2/2.1/2.0/1.20),
and its siblings FLINK-39902 (#28413) and FLINK-39903 (#28414) were already
backported here, so these fixes close the remaining parity gap. Without
FLINK-40009 in particular, the same race surfaces as a watchdog hang on 2.3
rather than a clean `TimeoutException`. Bundled into a single PR because all
four touch the same file.
## Brief change log
- Cherry-picked the four commits above (`-x`), each preserving its original
`[FLINK-xxxxx][tests]` message. The resulting `RescaleTimelineITCase.java` is
byte-identical to master's.
## Verifying this change
This change is a test-only stabilization backport and is covered by existing
tests:
- `RescaleTimelineITCase`
- `flink-runtime` `test-compile` passes on `release-2.3`.
