Subject [jira] [Commented] (HDFS-3331) Some admin methods in NN do not checkSuperuserPrivilege
Date Fri, 27 Apr 2012 15:46:51 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13263749#comment-13263749
] 

Robert Joseph Evans commented on HDFS-3331:
-------------------------------------------

Nicholas,  I really would like to see this in as part of 0.23 as well.  However, because 0.23
does not have HA the patch is not completely compatible.  So, I have created a version for
0.23.  Would you prefer that I file a separate JIRA for the port to 0.23, or is it OK with
you if I just tack that patch on here too?

and I am +1 (non-binding) on the fix.  I am not an HDFS expert so take it for what it is worth.
