Wei-Chiu Chuang commented on HADOOP-12847:
------------------------------------------
Thanks [~cnauroth] and [~xyao] for comments.
How do you think about support both http and https? Should the tool use an
option to specify the protocol, or let it attempt to connect to https and then
retry http?
For authentication, {{KerberosAuthenticator}} automatically falls back to
simple, so it should not require additional configuration.
On thing to consider is that https connection may need additional parameters to
supply the path to trust store file.
> 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.
