Benoy Antony commented on HDFS-5661:
------------------------------------
------the client presents this DT to authenticate with DN.
This s not correct. How can DN validate and read DT ?
The DT is issued by NN. client/agent can authenticate using DT only with NN.
Both NN/DN use
https://hadoop.apache.org/docs/current2/hadoop-project-dist/hadoop-common/HttpAuthentication.html
to authenticate a user's access to their http interfaces.

> If authentication is enabled on the web ui, then a cookie is used to keep
> track of the authentication information. There is normally a domain
> associated with the cookie. Since ip address doesn't have any domain , the
> cookie will not be sent by the browser while making http calls with ip
> address as the destination server.
> This will break browsing files system via web ui , if authentication is
> enabled.
