> Cannot reuse MiniOzoneCluster dir due to RocksDBCheckpointDiffer instance

> Key: HDDS-8557
> URL: https://issues.apache.org/jira/browse/HDDS-8557
> Project: Apache Ozone
> Issue Type: Bug
> Components: test
> Affects Versions: 1.4.0
> Reporter: Attila Doroszlai
> Assignee: Dave Teng
> Priority: Major
>
> {{RocksDBCheckpointDiffer}} has single instance per DB, which may cause
> failure if MiniOzoneCluster reuses the same directory between runs.
> Apparently this can happen if cluster is started in {{@BeforeAll}} method and
> test is repeated due to {{@Flaky}} annotation. The result is that if the
> first run fails, repeated attempts always run into the error.
