Review comment:
When the port number is not specified, it will be retrieved from config key
`ozone.om.address` if defined or fall back to default port 9862.
With this, we can eliminate, last lines from 109-111.

+
+ozone.om.address
+0.0.0.0:6789
+

+When we run command:

+
+The above command is essentially equivalent to:

+
+Note only the port number in the config is relevant. The host name in config
`ozone.om.address` is ignored in this case.
Review comment:
Can we reword this as:
Note: In the above case, port number from the config is used, whereas
hostname in the config `ozone.om.address` is ignored.
