+ hadoop.security.token.service.use_ip

+
+ 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.
