> Currently in a secured HDFS cluster, 401 error is returned when clicking the 
> "NameNode Logs" link.
> Looks like the cause of the issue is that the httpServer does not correctly 
> set the security handler and the user realm currently, which causes the 
> httpRequest.getRemoteUser (for the log URL) to return null and later be 
> overwritten to the default web name (e.g., "dr.who") by the filter. In the 
> meanwhile, in a secured cluster the log URL requires the http user to be an 
> administrator. That's why we see the 401 error.
