Bibin A Chundatt commented on YARN-4478:
----------------------------------------
IIUC {{new Configuration()}} is loading from classpath {{core-site.xml}} with
{{HADOOP_SECURITY_TOKEN_SERVICE_USE_IP}} value as {{false}}
{code}
public static final String HADOOP_SECURITY_TOKEN_SERVICE_USE_IP =
"hadoop.security.token.service.use_ip";
{code}
Since the value is loaded as false for hostname resolution
{{QualifiedHostResolver}} is used which is causing probelm
default value of {{hadoop.security.token.service.use_ip}} is true which should
have used {{StandardHostResolver}}. To check the same for yarn-client project
fix have uploaded patch in YARN-4982.
