> 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.
