Oleg Zhurakousky commented on YARN-1841:
----------------------------------------

More, in 
_org.apache.hadoop.yarn.server.resourcemanager.ApplicationMasterService_ line: 
123
The actual comment states IF authentication is not simple, but no IF statement 
is provided, 
{code}
    // If the auth is not-simple, enforce it to be token-based.
    serverConf = new Configuration(conf);
    serverConf.set(
        CommonConfigurationKeysPublic.HADOOP_SECURITY_AUTHENTICATION,
        SaslRpcServer.AuthMethod.TOKEN.toString());
{code}
