hue default password after new cluster install

Just installed CDH5.11.1 on a new cluster of 16 hosts. What's is the Hue WebUI default login? hue/hue ; admin/admin; cloudera/cloudera none of these works... Service seems to be running.

Re: hue default password after new cluster install

@HMC

 

The default uid/password is admin/admin. Below are few recommendations where you can focus to fix this issue

 

1. Adding required userid/pwd in hue.ini may help to fix this issue

2. Make sure you have created the hue user & granted required access on your meta database (mysql, postgresql, etc)

 Ex: create user 'hue' identified by 'hadoop1'; grant all on hue.* to hue;

3. if you have configured Hue with LDAP then the above credential will not work until you add admin user in your ldap

4. some configuration issue with hue

Re: hue default password after new cluster install

@HMC 

 

By default, CDH Hue has no superuser user/pass since the backend is "desktop.auth.backend.AllowFirstUserDjangoBackend" by default.

 

Whatever user and password you enter on first login will be the superuser.

If your authentication is failing, it means that someone already logged in with a username and password.

 

This page can help you change a password or create a new superuser (assuming you are still using desktop.auth.backend.AllowFirstUserDjangoBackend)
