 ## Known Issues & Limitations
 
 ### JobManager High-availability
-The Operator supports both [Kubernetes HA Services](https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/ha/kubernetes_ha/) and [Zookeeper HA Services](https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/ha/zookeeper_ha/) for providing High-availability for Flink jobs. The HA solution can benefit form using additional [Standby replicas](https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/ha/overview/), it will result in a faster recovery time, but Flink jobs will still restart when the Leader JobManager goes down.

 ### JobResultStore Resource Leak
 To mitigate the impact of [FLINK-27569](https://issues.apache.org/jira/browse/FLINK-27569) the operator introduced a workaround [FLINK-27573](https://issues.apache.org/jira/browse/FLINK-27573) by setting `job-result-store.delete-on-commit=false` and a unique value for `job-result-store.storage-path` for every cluster launch. The storage path for older runs must be cleaned up manually, keeping the latest directory always:
