Looks like there is an intermittent failure in `TestScmHaFinalization#testSnapshotFinalization`. However, it is the leader, not the SCM that finalized from a snapshot, that hit the error:
```

```
The error is
```
org.apache.hadoop.hdds.upgrade.TestScmHAFinalization.testSnapshotFinalization Time elapsed: 73.328 s <<< FAILURE!
java.lang.AssertionError

```
Which indicates the leader scmNode-1 did not cross the `FINALIZATION_COMPLETE` checkpoint in this check, even though the logs show that it already had earlier. I will need investigate this.
