----------------------------------------

[~jojochuang], thank you for posting the patch.

[~xyao], did you already have a patch in progress on an earlier JIRA for this, 
or am I mistaken?  I just want to figure out if there is a duplicate issue.  If 
not, then we can help code review this one.

> hadoop daemonlog should support https and SPNEGO for Kerberized cluster

> {{hadoop daemonlog}} is a simple, yet useful tool for debugging.
> However, it does not support https, nor does it support a Kerberized Hadoop 
> cluster.
> Using {{AuthenticatedURL}}, it will be able to support SPNEGO negotiation 
> with a Kerberized name node web ui. It will also fall back to simple 
> authentication if the cluster is not Kerberized.
