[jira] [Commented] (HDFS-4348) backup node document bug of 1.x
[ https://issues.apache.org/jira/browse/HDFS-4348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13619331#comment-13619331 ]
Luciano Curioni commented on HDFS-4348:
---------------------------------------
I don't believe this has been fixed, the documentation for 1.0.4 (http://hadoop.apache.org/docs/r1.0.4/hdfs_user_guide.html#Backup+Node
) still has the wrong statements.
