hevinhsu opened a new pull request, #8936:
URL: https://github.com/apache/ozone/pull/8936
## What changes were proposed in this pull request?
Speed up ```TestFailureHandlingByClient``` by using a shared
```MiniOzoneCluster```, reducing execution time by about 30%.
Please describe your PR in detail:
* Share a single ```MiniOzoneCluster``` instance across all test cases to
eliminate repeated cluster creation.
* Add a clean up method to make cluster reusable:
* Restart any stopped DNs.
* Run ```TestFailureHandlingByClient#testBlockWritesWithDnFailures```
first to avoid container cleanup, since only this test case needs to verify the
container block count.
