Disable authentication for name node UI (Web GUI)

[#1]

I can't find where could I disable authentication for a Web UI.

I'm using HDP 3.1.

Any help appreciated!

Check the config property hadoop.http.authentication.type, if this is set to kerberos , then accessing UIs would need kerberos credentials on client. By default this is et to kerberos in HDP 3.x version when cluster is kerberized. 

If you want to disable kerberos auth then change below config properties. 

->  Ambari > HDFS> Configs> in core-site

hadoop.http.authentication.type=simple

hadoop.http.authentication.simple.anonymous.allowed=true
