NameNode URL not accesible on Kerberos Cluster

 Hi Community,

 

I have a few of CDH clusters with Kerberos enabled but I've been facing issue to not able to access the NN URL. Here is error message:

=================

HTTP ERROR 401

Problem accessing /index.html. Reason:

    Authentication required

 

Powered by Jetty://

=================

 

 

However, Yarn NM, Job history and Spark URLs are just working fine. I've checked with my team who are using both Windows and Mac laptops and they are facing same issue. THis issue still happens with latest CDH5.10

 

Is there a workaround to address this issue for Mac OS?

 

Thanks,

Silaphet

Re: NameNode URL not accesible on Kerberos Cluster

You have HTTP Authentication turned on for HDFS.

CM > HDFS > Configuration > Enable Kerberos Authentication for HTTP Web-Consoles.

You can turn it off if you don't require it.

Or you can follow the below link to configure your browser to auth for the site.
