Krish,

What is the exact error you get in the browser when accessing nn using= the hostname?

Make sure that the hosts file of the machine that is running the brows= er can resolve the hostname.

Hi Johny,

I have all the entries for my namenode and datanode in the below forma= t in /etc/hosts
ipaddress=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 hostname=C2=A0=C2=A0=C2= =A0=C2=A0 fully_qualified_hostname

But still I am not sure why I am facing this issue.

Thanks
Krish

Hi Krish,

make sure that the host your using to acc= ess the UI can resolve the name of the UI.=C2=A0 You can do this by modifyi= ng the /etc/hosts/
for example, if the name of the UI host is namenode m= ake sure in the host file is like this : 192.168.1.10 namenode
