In HDP 3.x Spenego authentication will be enabled by default when you enable Kerberos
To access the UI you need to either configure Spnego auth in the browser OR disable spnego auth by setting the below properties in Hdfs =>Advanced core-site
hadoop.http.authentication.simple.anonymous.allowed = true
hadoop.http.authentication.type = simple

HTTP ERROR 401Problem accessing /ui2/. Reason: Unauthorized access
@Scharan thanks a lot for replying.The solution you suggested worked! But I just wanted to know whether modifying those two properties as you mentioned will cause any decrease in the security of my HDFS or cluster anyway?
@bvishal given properties will disable authentication for webui's and it will allow anonymous users to access the web UI's of hdfs, yarn, and mapreduce.
