adoroszlai opened a new pull request, #9329: URL: https://github.com/apache/ozone/pull/9329
## What changes were proposed in this pull request? `testPurgeKeysRequestBatching` is flaky (HDDS-13661) and annotated as such. _integration (flaky)_ repeats the failing test, and it passes on re-run, but the CI check is still reported as failure. Tests in `TestKeyDeletingService` are in nested classes, except `testPurgeKeysRequestBatching`, which causes this problem. This is fixed by moving `testPurgeKeysRequestBatching` into its own nested class. The test is still flaky, but successful re-try is no longer reported as failure. https://issues.apache.org/jira/browse/HDDS-13959 ## How was this patch tested?
