---------------------------------------
Summary: Reuse cluster across safe test classes
Key: HDDS-12183
URL: https://issues.apache.org/jira/browse/HDDS-12183
Project: Apache Ozone
Issue Type: Sub-task
Components: test
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
Cluster startup/shutdown is the most time-consuming part of the test for
several classes. Time breakdown by test case can be seen by setting
{{-Dsurefire.reportFormat=plain}}. For example, each test case in the
following three classes is finished in sub-second time, but total execution
time is 30+ seconds due to setup.

Safe integration tests (ones which do not stop / restart components) can be run
on the same {{MiniOzoneCluster}} to save time.
