Subject [jira] [Commented] (HDFS-5854) WebHDFS file browsing not working on secure cluster -or displaying meaningful errors
Date Thu, 30 Jan 2014 16:54:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13886773#comment-13886773
] 

Kihwal Lee commented on HDFS-5854:
----------------------------------

Related to or possible dupe of HDFS-5796? 

bq. Perhaps the NN should be internally invoking the servlets to get the response direct webhdfs
calls would return. That retains the cool new UI and allows flexibility for authentication.

I agree, but HDFS-5796 is not heading that way. Please chime in.

> webhdfs is on by default and the new NN status UI is coming up (after setting the {{
'dfs.web.authentication.kerberos.principal}} property -but the FS browser failing with error
code 401 -unauth. 
> That's inevitably security related -somehow.  But
> # the principal is set -or does httpfs-site.xml need to be filled in too?
> # if it is invalid, then some statement in the GUI should be provided
