[I] [test] Unstable test FlussAdminITCase.testClusterHealthDuringRollingUpgrade [fluss]
wuchong opened a new issue, #4722:
URL: https://github.com/apache/fluss/issues/4722
### Search before asking
- [x] I searched existing issues by test name, class, cluster health, and the GREEN/RED assertion and found no matching test-failure report.
### Fluss version
Development (`1.1-SNAPSHOT`, PR #4242).
### Description
`FlussAdminITCase.testClusterHealthDuringRollingUpgrade` fails in Java 11 / core:
https://github.com/apache/fluss/actions/runs/39205033760/job/117905902415?pr=4242
Observed in PR #4242, CI run `39205033760` (attempt 1, 2026-10-19), PR head `e8f8200f14315c2153900bdcb4e638e007e0eb92`, tested merge commit `4d8702cee717db6e0654eed6ecf83544694ae262`.
```
[ERROR] org.apache.fluss.client.admin.FlussAdminITCase.testClusterHealthDuringRollingUpgrade Time elapsed: 0.35 s <<< FAILURE!
org.opentest4j.AssertionFailedError:
expected: GREEN
but was: RED
at org.apache.fluss.client.admin.FlussAdminITCase.testClusterHealthDuringRollingUpgrade(FlussAdminITCase.java:2909)
at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

```
The failure is at the initial health assertion, after `waitAllReplicasReady(tableId, 3)` and before the test stops any TabletServer. The expected cluster status is `GREEN`, but `getClusterHealth()` returns `RED`.
[Failing assertion in the tested source](https://github.com/apache/fluss/blob/4d8702cee717db6e0654eed6ecf83544694ae262/fluss-client/src/test/java/org/apache/fluss/client/admin/FlussAdminITCase.java#L2909).
### Investigation
Check whether replica readiness and cluster-wide leader activation have both settled before the initial health assertion. The CI log establishes the assertion failure; its root cause still needs investigation.
