[PR] HDDS-8714. Fix flaky TestScmHAFinalization#testFinalizationWithRestart [ozone]
jojochuang opened a new pull request, #10790:
URL: https://github.com/apache/ozone/pull/10790
## Summary
- Fix flaky `TestScmHAFinalization#testFinalizationWithRestart[2]` (`AFTER_POST_FINALIZE_UPGRADE`), which timed out in `waitForFinalizationFromClient()` after restarting all SCMs.
- Speed up the mini-cluster in `init()` with fast heartbeat, pipeline creation, transaction buffer flush, and report intervals (matching other upgrade finalization tests), plus `hdds.scm.safemode.rule.refresh.interval=0s`.
- After SCM restart, wait for the leader to reach `FINALIZATION_COMPLETE` via `waitForScmToFinalize()` before polling the client for finalization status.
- Remove `@Flaky("HDDS-8714")`.
## Jira
https://issues.apache.org/jira/browse/HDDS-8714
## Test plan
- [x] `./hadoop-ozone/dev-support/checks/checkstyle.sh`
- [x] Fork flaky-test-check (10x10, Java 25): https://github.com/jojochuang/ozone/actions/runs/29600190535

Good to know. It was failing 11 out of 100 times for me before https://github.com/jojochuang/ozone/actions/runs/29468880808
Let me trigger more test runs.

Fix makes sense at a high level, but according to this [Jira comment](https://issues.apache.org/jira/browse/HDDS-8714?focusedCommentId=17844941&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17844941) 100 runs may not be enough to verify the problem is actually fixed.

Review Comment:
The PR description says that after SCM restart the test now waits for the leader to reach FINALIZATION_COMPLETE (via waitForScmToFinalize()) before polling the client in waitForFinalizationFromClient(). In the current diff, testFinalizationWithRestart() still goes directly from cluster.waitForClusterToBeReady() to waitForFinalizationFromClient(), so the described flakiness fix is not reflected in the code changes. Please either add the missing wait in the restart test (as described) or update the PR description/test plan to match what is actually changed.
