> When we run command "hadoop dfsadmin -refreshSuperUserGroupsConfiguration",
> it failed and report below message:
> 14/08/05 21:32:06 WARN security.MultiRealmUserAuthentication: The
> serverPrincipal = doesn't confirm to the standards
> refreshSuperUserGroupsConfiguration: null
> After check the code, I found the bug was triggered by below reasons:
> 1. We didn't set
> CommonConfigurationKeys.HADOOP_SECURITY_SERVICE_USER_NAME_KEY, which needed
> by RefreshUserMappingsProtocol. And in DFSAdmin, if no
> CommonConfigurationKeys.HADOOP_SECURITY_SERVICE_USER_NAME_KEY set, it will
> try to use DFSConfigKeys.DFS_NAMENODE_KERBEROS_PRINCIPAL_KEY:
> conf.set(CommonConfigurationKeys.HADOOP_SECURITY_SERVICE_USER_NAME_KEY,
> conf.get(DFSConfigKeys.DFS_NAMENODE_KERBEROS_PRINCIPAL_KEY, ""));
> 2. But we set DFSConfigKeys.DFS_NAMENODE_KERBEROS_PRINCIPAL_KEY in
> hdfs-site.xml
> 3. DFSAdmin didn't load hdfs-site.xml
