```
public static final ConfigOption<String> HA_STORAGE_PATH
```
    File system path (URI) where Flink persists metadata in high-availability setups.
  - HA_JOB_MANAGER_PORT_RANGE
```
public static final ConfigOption<String> HA_JOB_MANAGER_PORT_RANGE
```
    Optional port (range) used by the job manager in high-availability mode.
