[jira] Commented: (HADOOP-6647) balancer fails with "is not authorized for protocol interface NamenodeProtocol" in secure environment

    [ https://issues.apache.org/jira/browse/HADOOP-6647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12847566#action_12847566 ] 

Allen Wittenauer commented on HADOOP-6647:
------------------------------------------

Does that mean if I create a fake realm with the same short name I can run balancer?

> user logs in as hdfs/something@something and tries to run balancer.
> balancer is using NameNode Protocol which authorizes based on server principal key.
> but NameNode key is hdfs/_HOST@.. now. so it fails. 
> To fix we need to compare the short names only.
