----------------------------------
Summary: Add liveness probe to the example k8s resources files
Key: HDDS-1668
URL: https://issues.apache.org/jira/browse/HDDS-1668
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Elek, Marton
Assignee: Elek, Marton
In kubernetes resources we can define livebess probes which can help to detect
any failure. If the define port is not available the pod will be rescheduled.
We need to add the liveness probes to our k8s resource files.
Note: We shouldn't add readiness probes. Readiness probe is about the service
availability. The service/dns can be available only after the service is
restarted. This is not good for us as:
* We need DNS resolution during the startup (See OzoneManager.loadOMHAConfigs)
* We already implemented retry in case of missing DNS entries
