Review comment:
We should use
`HighAvailabilityMode.isHighAvailabilityModeActivated(conf)` instead here.
The following is the pre-check in Flink.
```
public int getReplicas() {
final int replicas =
flinkConfig.get(KubernetesConfigOptions.KUBERNETES_JOBMANAGER_REPLICAS);
if (replicas < 1) {
throw new IllegalConfigurationException(
String.format(
"'%s' should not be configured less than one.",
KubernetesConfigOptions.KUBERNETES_JOBMANAGER_REPLICAS.key()));
} else if (replicas > 1
&&
!HighAvailabilityMode.isHighAvailabilityModeActivated(flinkConfig)) {
throw new IllegalConfigurationException(
"High availability should be enabled when starting
standby JobManagers.");
}
return replicas;
}
```
