<description>
Controls whether tokens always use IP addresses.
DNS changes will not be detected if this option is enabled.
Existing client connections that break will always reconnect
to the IP of the original host. New clients will connect
to the host's new IP but fail to locate a token.
Disabling this option will allow existing and new clients
to detect an IP change and continue to locate the new host's token.
In secure multi-homed environments, this parameter will need to
be set to false on both cluster servers and clients (see HADOOP-7733).
If it is not set correctly, the symptom will be inability to
submit an application to YARN from an external client
(with error "client host not a member of the Hadoop cluster"),
or even from an in-cluster client if server failover occurs.
