--------------------------------------
Summary: Cannot reuse MiniOzoneCluster dir due to
RocksDBCheckpointDiffer instance cache
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
{{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.
